This little piece of code does something pretty cool. It will add an additional option to your settings menu with a link to "all settings" which will show you a complete list of all the settings you have within your database related to your WordPress site. The code below will only made this link visible to an administrator user and hide it for all other users.

        $height = HEADER_IMAGE_HEIGHT;
    }
    echo '<style>'.PHP_EOL;
    echo '.login h1 a {'.PHP_EOL; 
    echo '  background-image: url( '; header_image(); echo ' ) !important; '.PHP_EOL;

}
 

Modify the Login Logo & Image URL Link

Tested on: WordPress 3.0.1

This code will allow you to easily modify the WordPress Login page Logo as well as the href link and title text of this logo.

add_filter( 'login_headerurl', 'namespace_login_headerurl' );
/**
 * Replaces the login header logo URL
 *
 * @param $url
 */
function namespace_login_headerurl( $url ) {
    $url = home_url( '/' );
    return $url;
}

add_filter( 'login_headertitle', 'namespace_login_headertitle' );
/**
 * Replaces the login header logo title
 *
 * @param $title
 */
function namespace_login_headertitle( $title ) {
    $title = get_bloginfo( 'name' );
    return $title;
}

add_action( 'login_head', 'namespace_login_style' );
/**

 */
function namespace_login_style() {
    echo '<style>.login h1 a { background-image: url( ' . get_template_directory_uri() . '/images/logo.png ) !important; }</style>';
}

EDIT: If you want to use the site logo to replace the login logo, you can use the following to dynamically pull that information (tested on WP3.5):

function namespace_login_style() {
    if( function_exists('get_custom_header') ){
        $width = get_custom_header()->width;
        $height = get_custom_header()->height;
    } else {
        $width = HEADER_IMAGE_WIDTH;
        $height = HEADER_IMAGE_HEIGHT;
    }
    echo '<style>'.PHP_EOL;
    echo '.login h1 a {'.PHP_EOL; 
    echo '  background-image: url( '; header_image(); echo ' ) !important; '.PHP_EOL;
    echo '  width: '.$width.'px !important;'.PHP_EOL;
    echo '  height: '.$height.'px !important;'.PHP_EOL;
    echo '  background-size: '.$width.'px '.$height.'px !important;'.PHP_EOL;
    echo '}'.PHP_EOL;
    echo '</style>'.PHP_EOL;
}

Rimuovinotifica di aggiornamentopertuttigli utentitranne l'utente ADMIN

Testato su: WordPress 3.0.1

Questo codicegarantisce chenessun utente diverso da & quot; admin & quot; vengono avvisati da WordPress quando sono disponibili aggiornamenti ..

 // REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
   global $user_login;

   if ($user_login !== "admin") { // Change admin to the username that gets the updates
    add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
    add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );

Versionemodificatapermostrare solo lanotifica di aggiornamentopergli utenti amministratori (anziché soloper l'utente "admin"):

 // REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;

Remove Update Notification for all users except ADMIN User

Tested on: WordPress 3.0.1

This code will ensures that no users other than "admin" are notified by WordPress when updates are available..

    add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
   }

Changed version to only show update notification for admin users (as opposed to just the user 'admin'):

// REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;
       get_currentuserinfo();
       if (!current_user_can('update_plugins')) { // Checks to see if current user can update plugins

For what it's worth, there are a ton of great ideas for CONSTANTS that can be set on the Codex page Editing wp-config.php.

Remove "Wordpress" to "WordPress" filter

Tested on: WordPress 3.0.1

There was a filter added with WordPress version 3.0 that automatically converts all instances of "Wordpress" (no capital P) to "WordPress" (with a capital P) in post content, post titles, and comment text. Some people see this as intrusive, but I just have a need to mis-case WordPress from time to time and found the filter somewhat annoying.

// Remove annoying P filter
if(function_exists('capital_P_dangit')) {
    foreach ( array( 'the_content', 'the_title' ) as $filter )
        remove_filter( $filter, 'capital_P_dangit', 11 );

    remove_filter('comment_text', 'capital_P_dangit', 31 );

Enable Error Debugging And Logging To Use On Live Sites

This is a piece of code I wrote to make use of the WP_DEBUG constants that are normally disabled by default. Well, I created a way to not only enable WP_DEBUG so you can use it on a live site with no negative side-effects, but I also made use of the other debugging constants for forcing errors to be displayed, and for creating a log file of the errors and Notices in the /wp-content directory.

Drop this code in your wp-config.php file (AFTER YOU SAVE A BACKUP JUST IN CASE) and then you can pass the ?debug=1, 2, or 3 parameters at the end of any URL on your site.

?debug=1 = shows all errors/notices ?debug=2 = forces them to be displayed ?debug=3 = creates a debug.log file of all errors in /wp-content dir.

/**

if ( isset($_GET['debug']) && $_GET['debug'] == '1' ) {
    // Enable the reporting of notices during development - E_ALL
    define('WP_DEBUG', true);
} elseif ( isset($_GET['debug']) && $_GET['debug'] == '2' ) {
    // Must be true for WP_DEBUG_DISPLAY to work
    define('WP_DEBUG', true);
    // Force the display of errors
    define('WP_DEBUG_DISPLAY', true);
} elseif ( isset($_GET['debug']) && $_GET['debug'] == '3' ) {
    // Must be true for WP_DEBUG_LOG to work
    define('WP_DEBUG', true);
    // Log errors to debug.log in the wp-content directory
    define('WP_DEBUG_LOG', true);
}

I go into more detail on the guest post I wrote for Comluv if you're interested, here: http://comluv.com/dev/enable-debugging-and-logging-for-live-site-usage/

I'm still working on a way to make this either password protected, or preferrably somehow make it work on if (current_user_can('manage_themes') and is_logged_in().

But that's where it gets alot more tricky.

Nuovi ruolie funzionalità - Esegui solo una volta!

Litengo aportata dimano,questo èilmodo giusto perfarli senza unplugin. Impostano un singolo campo (prefix_user_roles)nel database delle opzionie non ènecessario unplug-inperimpostarli. Fare riferimento allapagina del Codexper unelenco dellefunzionalità disponibilie le descrizioni di ciò chefanno. Tu ho solobisogno di rimuovereil commento da uno di questiblocchi,caricare qualsiasipaginae quindi commentarli dinuovo! Qui sto creando un ruolo che abbia lefunzionalità di cui hobisogno:

 /* Funzionalità */

//Per aggiungereilnuovo ruolo,utilizzando "international" comenomebrevee
//"International Blogger" comenome visualizzatonell'elenco utentie nellapagina dimodifica:
/*
add_role ('international','International Blogger',array (
    'read'=>true,//True consente quella capacità,False la rimuove specificamente.
    'edit_posts'=> vero,
    'delete_posts'=> vero,
    'edit_published_posts'=> vero,
    'publish_posts'=> vero,
    'edit_files'=> vero,
    'import'=> vero,
    'upload_files'=>true//lastin arraynon habisogno di virgola!
));
*/


//Per rimuoverne uno o rimuovere uno dei valoripredefiniti:
/*
remove_role ("internazionale");
*/
 

A volte è utile aggiungere/rimuovere da un ruoloesistentepiuttosto che rimuovernee aggiungernenuovamente uno. Anchein questo caso,devi solo rimuovereil commento,ricaricare unapaginae quindi commentarla dinuovo. Ciòmemorizzerà correttamenteil ruolo/capacitànellatabella delle opzioni. (Ciò consente allo sviluppatore di controllarlie rimuoveil sovraccarico deipluginingombranti chefanno la stessa cosa.) Qui sto cambiandoil ruolo dell'autorepereliminarei loropostpubblicati (impostazionepredefinita),ma consentendo loro la capacità dimodificarei loropostpubblicati (cosa chenon èpossibileper questo ruoloperimpostazionepredefinita) - utilizzando * add_cap * o * remove_cap *.

 /*
$edit_role=get_role ('autore');
   $edit_role- > add_cap ('edit_published_posts');
   $edit_role- > remove_cap ('delete_published_posts');
*/
 

Tengo unfoglio di calcolo con lagriglia dallapagina Codexperi siti chemodificanoin questomodo,cosìposso ricordare come sonoimpostate le cose,anche se andràbene lasciareil codice commentatonelfilefunctions.php. Non lasciare questiesempinon commentati,altrimenti scriverànel database ad ogni caricamento dellapagina!

New Roles and Capabilities - Only run once!

I keep these handy, this is the right way to do them without a plugin. They set a single field (prefix_user_roles) in the options database, and you don't need a plugin to set them. Refer to the Codex page for a list of what capabilities are available and descriptions for what they do. You only need to uncomment one of these blocks, load any page and then comment them again! Here I'm creating a role that's got the capabilities I need:

/* Capabilities */

// To add the new role, using 'international' as the short name and
// 'International Blogger' as the displayed name in the User list and edit page:
/*
add_role('international', 'International Blogger', array(
    'read' => true, // True allows that capability, False specifically removes it.
    'edit_posts' => true,
    'delete_posts' => true,
    'edit_published_posts' => true,
    'publish_posts' => true,
    'edit_files' => true,
    'import' => true,
    'upload_files' => true //last in array needs no comma!
));
*/


// To remove one outright or remove one of the defaults:
/* 
remove_role('international');
*/

It's sometimes handy to add/remove from an existing role rather than removing and re-adding one. Again, you only need to uncomment it, reload a page and then comment it again. This will store the role/capability properly in the options table. (This allows you, the developer to control them and removes the overhead of the bulky plugins that do the same thing.) Here I'm changing the author role to delete their published posts (the default), but allowing them the capability to edit their published posts (which isn't possible for this role by default)-- using *add_cap* or *remove_cap*.

/*
$edit_role = get_role('author');
   $edit_role->add_cap('edit_published_posts');
   $edit_role->remove_cap('delete_published_posts');
*/

I keep a spreadsheet with the grid from the Codex page for sites that modify this way, so I can remember how things are set, though leaving the commented out code in your functions.php file will work to. Don't leave these examples uncommented, or it will write to the database with each page load!

Una delle cose chemi fannoimpazzire è un'area di amministrazione di Wordpressingombra. Uno deglielementi che ora ho sempreimpostato dall'inizionelmiofilefunctions.php è rimuovereil MetaBox dell'autoree le Opzioni schermoe quindi aggiungere l'opzionenelmetabox dipubblicazione. Secondome questo ha sensoe mantiene le cosepulite. Ciò rispetta anche le autorizzazioni applicabili.

Per raggiungere questo obiettivo,copiae incollail seguente codiceneltuofilefunctions.php.

Remove Author Metabox/Options & Move to Publish MetaBox

Tested on: Wordpress 3.0.1

One of the things that drive me crazy is a cluttered Wordpress Admin area. One of the elements which I now always setup from the start in my functions.php file is removing the Author MetaBox and Screen Options and then adding the option into the publish metabox. In my opinion this just makes sense and keep things clean. This also respects applicable permissions.

To achieve this goal, just copy and past the following code into your functions.php file.

If you feel there is a better way of doing this please suggest.

NOTE: UPDATED THE CODE TO FIX A CODING ISSUE

// MOVE THE AUTHOR METABOX INTO THE PUBLISH METABOX
add_action( 'admin_menu', 'remove_author_metabox' );
add_action( 'post_submitbox_misc_actions', 'move_author_to_publish_metabox' );
function remove_author_metabox() {
    remove_meta_box( 'authordiv', 'post', 'normal' );
}
function move_author_to_publish_metabox() {
    global $post_ID;
    $post = get_post( $post_ID );
    echo '<div id="author" class="misc-pub-section" style="border-top-style:solid; border-top-width:1px; border-top-color:#EEEEEE; border-bottom-width:0px;">Author: ';
    post_author_meta_box( $post );
    echo '</div>';

Determina rapidamenteil server & amp; Dettagli dell'ambiente

Se disponi dipiù servere più ambienti come ambienti di sviluppo,controllo qualitàe produzione,questopuòesseremolto utile.

Peri miei sistemi,l'ambiente è determinato dalleprime 3 lettere delnome host,ma questopotrebbeesserefacilmentemodificatoin base alletueesigenze.

 add_action( 'admin_notices', 'report_environment_status', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname('n');
    switch (strtolower(substr($server,0,3))) {
        case 'pXX':
            $msg = "PRODUCTION";
            break;
        case 'qXX':
            $msg = "QA";
            break;
        case 'dXX':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = 'UNKNOWN';
    }
    echo "<div id='update-nag'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}
 

Questomi ha salvatomolte volte dall'effettuare aggiornamenti all'ambiente sbagliato.

Quickly Determine Server & Environment Details

If you have multiple servers and multiple environments such as development, QA, and production environments, this can be very useful.

For my systems, environment is determined by the first 3 letters of the hostname, but this could easily be changed to whatever suits your needs.

add_action( 'admin_notices', 'report_environment_status', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname('n');
    switch (strtolower(substr($server,0,3))) {
        case 'pXX':
            $msg = "PRODUCTION";
            break;
        case 'qXX':
            $msg = "QA";
            break;
        case 'dXX':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = 'UNKNOWN';
    }
    echo "<div id='update-nag'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}

This has saved me many times from making updates to the wrong environment.

You can also turn this into a plugin and network activate it so all sites get the notification.

Remove XML-RPC when not in use for performance boost

Tested on: Wordpress 3.0.1

WordPress uses a CURL operation to test for SSL capability for XML-RPC. If you're using XML-RPC but not using, then you can remove the filter. This is a small performance boost (since basically WP does a cURL GET on the https url and either 1) gets a denied message, or 2) times out, and it can take upwards of 5 seconds), but in our case it actually prevented a gateway timeout where a proxy was timing out before the cURL GET was timing out rendering XML-RPC unusable.

}

Then call the field with a single line

<?php get_custom_field('custom-field-name', TRUE); ?>

Restituisceilnumero di commenti

È come count_user_posts(),ma restituisceinveceilnumero di commenti:

 function count_user_comments($id) {
global $wpdb;
$users = $wpdb->get_var("
        SELECT COUNT( * ) AS total
        FROM $wpdb->comments
        WHERE comment_approved = 1 
        AND user_id = $id");
return $users;
}
 

Altro: contai post dell'utente (inclusii tipi dipostpersonalizzati) oi commenti:

 function atom_count($user_id, $what_to_count = 'post') {
  global $wpdb;    
  $where = $what_to_count == 'comment' ? "WHERE comment_approved = 1 AND user_id = {$user_id}" : get_posts_by_author_sql($what_to_count, TRUE, $user_id);
  $from = "FROM ".(($what_to_count == 'comment') ? $wpdb->comments : $wpdb->posts);    
  $count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) {$from} {$where}"));
  return $count;
}
 

Esempi di utilizzo:

<?php echo atom_count(1, 'movie'); // displays 'movie' post type count ?>

<?php echo atom_count(1, 'comment'); // displays comment count ?>

Return the number of comments

This is like count_user_posts(), but returns the number of comments instead:

function count_user_comments($id) {
global $wpdb;
$users = $wpdb->get_var("
        SELECT COUNT( * ) AS total
        FROM $wpdb->comments
        WHERE comment_approved = 1 
        AND user_id = $id");
return $users;
}

More: Count User's posts (including custom post types) or comments:

function atom_count($user_id, $what_to_count = 'post') {
  global $wpdb;    
  $where = $what_to_count == 'comment' ? "WHERE comment_approved = 1 AND user_id = {$user_id}" : get_posts_by_author_sql($what_to_count, TRUE, $user_id);
  $from = "FROM ".(($what_to_count == 'comment') ? $wpdb->comments : $wpdb->posts);    
  $count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) {$from} {$where}"));
  return $count;
}

Usage examples:

<?php echo atom_count(1, 'movie'); // displays 'movie' post type count ?>

<?php echo atom_count(1, 'comment'); // displays comment count ?>

Post Word Count

Tested on: Wordpress 3.0.1

(Originally extracted from the Post Word Count plug-in by Nick Momrick)

Adds a count of total published words to the bottom of the "Right Now" box on the admin dashboard. Useful if you're using your blog as an outlet for something like NaNoWriMo or if you just want to keep track of how prolific your blogging skills have become.

function post_word_count() {
    $count = 0;
    $posts = get_posts( array(
        'numberposts' => -1,
        'post_type' => array( 'post', 'page' )
    ));
    foreach( $posts as $post ) {
        $count += str_word_count( strip_tags( get_post_field( 'post_content', $post->ID )));
    }
    $num =  number_format_i18n( $count );
    // This block will add your word count to the stats portion of the Right Now box
    $text = _n( 'Word', 'Words', $num );
    echo "<tr><td class='first b'>{$num}</td><td class='t'>{$text}</td></tr>";
    // This line will add your word count to the bottom of the Right Now box.
    echo '<p>This blog contains a total of <strong>' . $num . '</strong> published words!</p>';
}

// add to Content Stats table
add_action( 'right_now_content_table_end', 'post_word_count');
// add to bottom of Activity Box
add_action('activity_box_end', 'post_word_count');

Caricamento degli scriptin modo condizionale

Ecco unmodoper caricaregli script solo se èpresente unparticolare shortcode o widget. fonte: Caricamento di script solo se èpresente unparticolare shortcode o widget

 function has_my_shortcode($posts) {

    wp_print_scripts('my_script');
}
    return $posts;
}
add_action('the_posts', 'has_my_shortcode');
 

Edecco come caricaregli script solo se èpresente un certo widget

Per caricare lo script solonellapaginain cui è caricatoil widget,dovrai aggiungereil codiceis_active_widget (),nellatua classe widget. Adesempio,guardail widget dei commenti recentipredefinito (wp-includes/default-widgets.php,riga 602):

 class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array('classname' => 'widget_recent_comments', 'description' => __( 'The most recent comments' ) );
        $this->WP_Widget('recent-comments', __('Recent Comments'), $widget_ops);
        $this->alt_option_name = 'widget_recent_comments';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( 'wp_head', array(&$this, 'recent_comments_style') );
        add_action( 'comment_post', array(&$this, 'flush_widget_cache') );
        add_action( 'transition_comment_status', array(&$this, 'flush_widget_cache') );
    }
 

Loading scripts conditionally

Here is a way to load scripts only if a particular shortcode or widget is present. source: Loading scripts only if a particular shortcode or widget is present

function has_my_shortcode($posts) {
    if ( empty($posts) )
        return $posts;
    $found = false;
    foreach ($posts as $post) {
        if ( stripos($post->post_content, '[my_shortcode') )
            $found = true;
            break;
        }
    if ($found){
        $urljs = get_bloginfo( 'template_directory' ).IMP_JS;
    wp_register_script('my_script', $urljs.'myscript.js' );
    wp_print_scripts('my_script');
}
    return $posts;
}
add_action('the_posts', 'has_my_shortcode');

And here is how to load scripts only if a certain widget is present

To load the script in the page where the widget is loaded only, you will have to add the is_active_widget() code, in you widget class. E.g., see the default recent comments widget (wp-includes/default-widgets.php, line 602):

class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array('classname' => 'widget_recent_comments', 'description' => __( 'The most recent comments' ) );
        $this->WP_Widget('recent-comments', __('Recent Comments'), $widget_ops);
        $this->alt_option_name = 'widget_recent_comments';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( 'wp_head', array(&$this, 'recent_comments_style') );
        add_action( 'comment_post', array(&$this, 'flush_widget_cache') );
        add_action( 'transition_comment_status', array(&$this, 'flush_widget_cache') );
    }

        $classes[] = 'section-' . $post_data['post_name'];
    }
    return $classes;
}

This filter adds a unique body class based on the highest level parent of the current page. I use this for sites that have specific colours or layouts for each section of the site. It works best with sites based around pages. CSS examples:

.section-about { background: red; }
.section-portfolio { background: blue; }

Your theme must also make use of the body_class function.

Fix oEmbed flash objects

/***************************************************************

function my_oembed_wmode( $embed ) {
    if ( strpos( $embed, '<param' ) !== false ) {
        $embed = str_replace( '<embed', '<embed wmode="transparent" ', $embed );
        $embed = preg_replace( '/param>/', 'param><param name="wmode" value="transparent" />', $embed, 1);
    }
    return $embed;
}

I have had problems in the past where oEmbed Flash objects collide with drop down navigation menus. This filter fixes that problem by adding a transparent window mode to the embeds.

Remove the "comments" column from Admin page list

/***************************************************************

I hardly ever make use of commenting on pages and this helps keep things tidy in the WordPress dashboard.

Controlla se unpost ha contenutiincorporati.

Controlla se unpost ha contenutoincorporato,funziona all'interno del ciclo utilizzando l'ID delpost corrente o,in alternativa,puòesserepassato un IDper determinareilpostper controllareil contenutoincorporato.

 function has_embed( $post_id = false ) {
    if( !$post_id ) $post_id = get_the_ID();
    else $post_id = absint( $post_id );
    if( !$post_id ) return false;

    $post_meta = get_post_custom_keys( $post_id );
    $post_meta = array_map( 'trim' , $post_meta );

    foreach( $post_meta as $meta ) {
        if( '_oembed' != substr( $meta , 0 , 7 ) )
            continue;
        return true;
    }
    return false;
}
 

Utilizzeresti lafunzionenello stessomodoin cui controlli se unpost ha untag ..

 if( has_embed() ) {
   // do whatever
}
 

Lafunzione restituiscetrue se vienetrovato unembed,falsein caso dierrore.

Check if a post has embedded content.

Check if a post has embedded content, works inside the loop using the current post's ID, or alternatively can be passed an ID to determine the post to check for embedded content.

function has_embed( $post_id = false ) {
    if( !$post_id ) $post_id = get_the_ID();
    else $post_id = absint( $post_id );
    if( !$post_id ) return false;

    $post_meta = get_post_custom_keys( $post_id );
    $post_meta = array_map( 'trim' , $post_meta );

    foreach( $post_meta as $meta ) {
        if( '_oembed' != substr( $meta , 0 , 7 ) )
            continue;
        return true;
    }
    return false;
}

You'd use the function in the same way you check if a post has a tag..

if( has_embed() ) {
   // do whatever
}

Function returns true if an embed is found, false on fail.

Visualizzai post di diversitipi dipostpersonalizzati sulla homepage

Inserendoil seguente codicein fondo a questopostneltuofilefunctions.phppuoifarein modo che wordpress visualizzi automaticamentei post di diversitipi dipostpersonalizzati che hai creato. Attualmente,perimpostazionepredefinita,wordpressmostra soloi post che appartengono ai & quot;post & quot;tipo dipost.

Nell'esempiofornito di seguito sarànecessariomodificare la sezione che chiama:

 $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
 

Coni tuoitipi dipostpersonalizzati che desideriincluderenei risultati dell'elenco deipost della homepage. In questo caso chiediamo a wordpress di restituircituttii post appartenenti al & quot;post & quot;predefinitoe & quot;pagina & quot;post_type quindi chiedendo a wordpress diincludere ancheiltipo dipostpersonalizzato che abbiamo creatoperi & quot; servizi & quot;e infineiltipo dipost wordpresspredefinito di & quot; allegato & quot;il che significa semplicemente che ogni volta che viene aggiunto qualcosa alla libreriamultimediale,verrà automaticamente visualizzatonella homepage come voce separata.

 // CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( 'pre_get_posts', 'my_homepage_post_list' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars['suppress_filters'] )
        $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
    return $query;
}
 

Puoi anche utilizzare questa querypersonalizzatain posizioni diverse,adesempioin unfeedpersonalizzatotramite qualcosa di simile

 if (( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed())
 

Display Posts from Different Custom Post Types on homepage

By dropping the following code on the bottom of this post into your functions.php file you can get wordpress to automatically display posts from different custom post types you have created. Currently by default wordpress only display posts which belong to the default "posts" post type.

In the example provided below you will need to change the section which calls:

$query->set( 'post_type', array('post', 'page', 'services', 'attachment'));

With your own custom post types which you would like to include in the homepage post list results. In this case we are asking wordpress to return to us all posts belonging to the default "post" and "page" post_type then asking wordpress to also include the custom post type we created for "services" and finally the default wordpress post type of "attachment" which just means that anytime something is added to the media library it will automatically get displayed on the homepage as a separate entry.

// CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( 'pre_get_posts', 'my_homepage_post_list' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars['suppress_filters'] )
        $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
    return $query;
}

You can also utilize this custom query in different locations, such as in a custom feed through something like this

if (( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed())

Rimuovii campipredefinitiinformazioni di contattoprofilo utentee sostituiscili con qualcosa dipiù utilizzabile

La secondaparte di questafunzione ègià statamenzionata sopra,ma la rimozione dei campipredefiniti - AIM,Yahoo IMe Jabber/Google Talk -non ancora:

 function update_contact_methods( $contactmethods ) {

// Remove annoying and unwanted default fields  
unset($contactmethods['aim']);  
unset($contactmethods['jabber']);  
unset($contactmethods['yim']);  

// Add new fields  
$contactmethods['phone'] = 'Phone';  
$contactmethods['mobile'] = 'Mobile';  
$contactmethods['address'] = 'Address';  

return $contactmethods;
}
add_filter('user_contactmethods', 'update_contact_methods');
 

Ovviamentepuoi aggiungeretuttii campi che desideri (vediesempiprecedenti all'inizio di questothread) sotto "Aggiunginuovi campi"

Remove default fields contact info user profile and replace them with something more usable

The second part of this function has already been mentioned above, but removing the default fields - AIM, Yahoo IM and Jabber/Google Talk - not yet:

function update_contact_methods( $contactmethods ) {

// Remove annoying and unwanted default fields  
unset($contactmethods['aim']);  
unset($contactmethods['jabber']);  
unset($contactmethods['yim']);  

// Add new fields  
$contactmethods['phone'] = 'Phone';  
$contactmethods['mobile'] = 'Mobile';  
$contactmethods['address'] = 'Address';  

return $contactmethods;
}
add_filter('user_contactmethods', 'update_contact_methods');

Of course you can add as many fields as you want (see previous examples earlier in this thread) under "Add new fields"

Pre-populating post types

Here is one for this collection.

add_filter( 'default_content', 'my_editor_content' );

function my_editor_content( $content ) {

This can come in handy for when you need to post the same info over and over again with slight differences.

function add_google_analytics() {
?>
<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");

        pageTracker._trackPageview();
    } catch(err) {}</script>
<?php
}

add_action('wp_footer', 'add_google_analytics');

Just be sure to replace UA-XXXXXXX-X with your own Google tracking code...
