Come puoi verificare se ti trovi in una determinata pagina nella sezione WP Admin?Ad esempio, come posso verificare se sono nella pagina Utenti> Il tuo profilo?

Ilmodoperfarlo è usare l'hook 'admin_enqueue_scripts'permetterein codai file di cui haibisogno.Questo hook riceverà un $ hook_suffix relativo allapagina corrente che viene caricata:

 function my_admin_enqueue($hook_suffix) {
    if($hook_suffix == 'appearance_page_theme-options') {
        wp_enqueue_script('my-theme-settings', get_template_directory_uri() . '/js/theme-settings.js', array('jquery'));
        wp_enqueue_style('my-theme-settings', get_template_directory_uri() . '/styles/theme-settings.css');
        ?>
        <script type="text/javascript">
        //<![CDATA[
        var template_directory = '<?php echo get_template_directory_uri() ?>';
        //]]>
        </script>
        <?php
    }
}
add_action('admin_enqueue_scripts', 'my_admin_enqueue');
 

The way to do this is to use the 'admin_enqueue_scripts' hook to en-queue the files you need. This hook will get passed a $hook_suffix that relates to the current page that is loaded:

function my_admin_enqueue($hook_suffix) {
    if($hook_suffix == 'appearance_page_theme-options') {
        wp_enqueue_script('my-theme-settings', get_template_directory_uri() . '/js/theme-settings.js', array('jquery'));
        wp_enqueue_style('my-theme-settings', get_template_directory_uri() . '/styles/theme-settings.css');
        ?>
        <script type="text/javascript">
        //<![CDATA[
        var template_directory = '<?php echo get_template_directory_uri() ?>';
        //]]>
        </script>
        <?php
    }
}
add_action('admin_enqueue_scripts', 'my_admin_enqueue');

Esiste una variabileglobalein wp-admin chiamata $pagenow che contieneilnome dellapagina corrente,adesempioedit.php,post.php,ecc.

Puoi anche controllare la richiesta $ _GETper restringere ulteriormente latuaposizione,adesempio:

 global $pagenow;
if (( $pagenow == 'post.php' ) && ($_GET['post_type'] == 'page')) {

    // editing a page

    }

if ($pagenow == 'users.php') {

    // user listing page

    }

if ($pagenow == 'profile.php') {

    // editing user profile page

    }
 

There is a global variable in wp-admin called $pagenow which holds name of the current page, ie edit.php, post.php, etc.

You can also check the $_GET request to narrow your location down further, for example:

global $pagenow;
if (( $pagenow == 'post.php' ) && ($_GET['post_type'] == 'page')) {

    // editing a page

    }

if ($pagenow == 'users.php') {

    // user listing page

    }

if ($pagenow == 'profile.php') {

    // editing user profile page

    }

Ilmetodopiù completo è get_current_screen aggiuntoin WordPress 3.1

 $screen = get_current_screen();
 

restituisce

 WP_Screen Object (
    [action] => 
    [base] => post
    [id] => post
    [is_network] => 
    [is_user] => 
    [parent_base] => edit
    [parent_file] => edit.php
    [post_type] => post
    [taxonomy] => 
)
 

The most comprehensive method is get_current_screen added in WordPress 3.1

$screen = get_current_screen();

returns

WP_Screen Object (
    [action] => 
    [base] => post
    [id] => post
    [is_network] => 
    [is_user] => 
    [parent_base] => edit
    [parent_file] => edit.php
    [post_type] => post
    [taxonomy] => 
)

Offrire unmetodo/approccio alternativo alla domandaprecedente.

 // When you are viewing the users list or your editing another user's profile
add_action( 'admin_print_scripts-users.php', 'your_enqueue_callback' );

// When you are editing your own profile
add_action( 'admin_print_scripts-profile.php', 'your_enqueue_callback' );

function your_enqueue_callback() {
    wp_enqueue_script( .. YOUR ENQUEUE ARGS .. );
}
 

Questometodoprende dimira lepagine specifichein modopiù direttoedevita di averbisogno della logica condizionale all'interno del callback (perché haigiàfatto quella distinzionenell'hook selezionato).

To offer an alternative method/approach to the above question.

// When you are viewing the users list or your editing another user's profile
add_action( 'admin_print_scripts-users.php', 'your_enqueue_callback' );

// When you are editing your own profile
add_action( 'admin_print_scripts-profile.php', 'your_enqueue_callback' );

function your_enqueue_callback() {
    wp_enqueue_script( .. YOUR ENQUEUE ARGS .. );
}

This method targets the specific pages more directly and avoids needing conditional logic inside your callback(because you've already made that distinction in the selected hook).

Trovo strano chenessuno abbiamenzionatoilfatto che lafunzione add_menu_page restituisce un action hook chepuoi usarepereseguire determinate azioni solo su quellepagine

 $hook = add_menu_page($menu_title, $page_title, $capability, $slug, $function, $icon_url, $position);
add_action( 'load-' . $hook, 'my_admin_enqueue_scripts' );
function my_admin_enqueue_scripts() {
    wp_enqueue_script(/*...*/);
    wp_enqueue_style(/*...*/);
}
 

Seti serve $ hooke non hai aggiunto lapagina delmenu da solo,il documento è qui

Adesempio l'hookper unapagina dimenu diprimo livello è

load-toplevel_page_ $ MenuSlug

L'hookper unapagina di sottomenu è

carica- $ MenuSlug_page_ $ SubMenuSlug

Seguendo questa logica,l'hookper lapagina delprofilo dell'utente è

load-users_page_profile

I find it weird that no one has mentioned the fact that the add_menu_page function returns an action hook which you can use to do certain actions only on those pages

$hook = add_menu_page($menu_title, $page_title, $capability, $slug, $function, $icon_url, $position);
add_action( 'load-' . $hook, 'my_admin_enqueue_scripts' );
function my_admin_enqueue_scripts() {
    wp_enqueue_script(/*...*/);
    wp_enqueue_style(/*...*/);
}

If you need the $hook and you didn't add the menu page yourself the doc is here

For instance the hook for a top level menu page is

load-toplevel_page_$MenuSlug

The hook for a submenu page is

load-$MenuSlug_page_$SubMenuSlug

Following that logic, the hook for the user's profile page is

load-users_page_profile
