Come visualizzare gli ultimi 3 post (post recenti) in una pagina statica?

Di solito utilizzo questo approccio:

approccio sbagliato

 <?php query_posts( array(
   'category_name' => 'news',
   'posts_per_page' => 3,
)); ?>

<?php if( have_posts() ): while ( have_posts() ) : the_post(); ?>

   <?php the_excerpt(); ?>
   <?php endwhile; ?>

<?php else : ?>

   <p><?php __('No News'); ?></p>

<?php endif; ?>
 

Con l'aiuto di @swissspidy ilmodo corretto è questo:

 <?php 
   // the query
   $the_query = new WP_Query( array(
     'category_name' => 'news',
      'posts_per_page' => 3,
   )); 
?>

<?php if ( $the_query->have_posts() ) : ?>
  <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

    <?php the_title(); ?>
    <?php the_excerpt(); ?>

  <?php endwhile; ?>
  <?php wp_reset_postdata(); ?>

<?php else : ?>
  <p><?php __('No News'); ?></p>
<?php endif; ?>
 

Vedi @codex per ulterioriinformazioni.

I usually use this approach:

wrong approach

<?php query_posts( array(
   'category_name' => 'news',
   'posts_per_page' => 3,
)); ?>

<?php if( have_posts() ): while ( have_posts() ) : the_post(); ?>

   <?php the_excerpt(); ?>
   <?php endwhile; ?>

<?php else : ?>

   <p><?php __('No News'); ?></p>

<?php endif; ?>

With the help of @swissspidy the correct way is this one:

<?php 
   // the query
   $the_query = new WP_Query( array(
     'category_name' => 'news',
      'posts_per_page' => 3,
   )); 
?>

<?php if ( $the_query->have_posts() ) : ?>
  <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

    <?php the_title(); ?>
    <?php the_excerpt(); ?>

  <?php endwhile; ?>
  <?php wp_reset_postdata(); ?>

<?php else : ?>
  <p><?php __('No News'); ?></p>
<?php endif; ?>

See @codex for more info.

Dipende da cosa stai cercando. Se desideri creare una "pagina dipost",ovvero creare unnuovofilemodello dipagina,puoi creare un ciclo secondario su quellapagina.

Il codice ha unesempio di questoedecco un altroesempiomolto ridotto.

 <?php
/*
Template Name: Page of Posts
*/
get_header(); 
?>

<?php while( have_posts() ): the_post(); /* start main loop */ ?>

    <h1><?php the_title(); ?></h1>

    <?php
        /* Start Secondary Loop */
        $other_posts = new WP_Query( /*maybe some args here? */ );
        while( $others_posts->have_posts() ): $other_posts->the_post(); 
    ?>
        You can do anything you would in the main loop here and it will
        apply to the secondary loop's posts
    <?php 
        endwhile; /* end secondary loop */ 
        wp_reset_postdata(); /* Restore the original queried page to the $post variable */
    ?>

<?php endwhile; /* End the main loop */ ?>
 

Se stai cercando qualcosa chepuoiinserirein qualsiasipagina,la soluzionemigliore sarebbe uno shortcode . Dovresti creare uno shortcode che recuperi diversiposte li restituiscain unelenco (o quello che vuoi). Unesempio:

 <?php
add_action( 'init', 'wpse36453_register_shortcode' );
/**
 * Registers the shortcode with add_shortcode so WP knows about it.
 */
function wpse36453_register_shortcode()
{
    add_shortcode( 'wpse36453_posts', 'wpse36453_shortcode_cb' );
}

/**
 * The call back function for the shortcode. Returns our list of posts.
 */
function wpse36453_shortcode_cb( $args )
{
    // get the posts
    $posts = get_posts(
        array(
            'numberposts'   => 3
        )
    );

    // No posts? run away!
    if( empty( $posts ) ) return '';

    /**
     * Loop through each post, getting what we need and appending it to 
     * the variable we'll send out
     */ 
    $out = '<ul>';
    foreach( $posts as $post )
    {
        $out .= sprintf( 
            '<li><a href="%s" title="%s">%s</a></li>',
            get_permalink( $post ),
            esc_attr( $post->post_title ),
            esc_html( $post->post_title )
        );
    }
    $out .= '</ul>';
    return $out;
}
 

It kind of depends on what you're going for. If you want to do a "page of posts" -- other words, create a new page template file -- you can create a secondary loop on that page.

The codex has an example of this and here's another, very stripped down example.

<?php
/*
Template Name: Page of Posts
*/
get_header(); 
?>

<?php while( have_posts() ): the_post(); /* start main loop */ ?>

    <h1><?php the_title(); ?></h1>

    <?php
        /* Start Secondary Loop */
        $other_posts = new WP_Query( /*maybe some args here? */ );
        while( $others_posts->have_posts() ): $other_posts->the_post(); 
    ?>
        You can do anything you would in the main loop here and it will
        apply to the secondary loop's posts
    <?php 
        endwhile; /* end secondary loop */ 
        wp_reset_postdata(); /* Restore the original queried page to the $post variable */
    ?>

<?php endwhile; /* End the main loop */ ?>

If you're looking for something that you can drop into any page, the best solution would be a shortcode. You would need to create a shortcode that fetches several posts and returns them in a list (or whatever you want). An example:

<?php
add_action( 'init', 'wpse36453_register_shortcode' );
/**
 * Registers the shortcode with add_shortcode so WP knows about it.
 */
function wpse36453_register_shortcode()
{
    add_shortcode( 'wpse36453_posts', 'wpse36453_shortcode_cb' );
}

/**
 * The call back function for the shortcode. Returns our list of posts.
 */
function wpse36453_shortcode_cb( $args )
{
    // get the posts
    $posts = get_posts(
        array(
            'numberposts'   => 3
        )
    );

    // No posts? run away!
    if( empty( $posts ) ) return '';

    /**
     * Loop through each post, getting what we need and appending it to 
     * the variable we'll send out
     */ 
    $out = '<ul>';
    foreach( $posts as $post )
    {
        $out .= sprintf( 
            '<li><a href="%s" title="%s">%s</a></li>',
            get_permalink( $post ),
            esc_attr( $post->post_title ),
            esc_html( $post->post_title )
        );
    }
    $out .= '</ul>';
    return $out;
}

C'è unaguidaper questo casoprecisonel codice wordpress.Guardalo qui : Incollo quiil codiceperché èpiuttostobreve,permaggioriinformazioni vai sul sito wordpress.org.

 <?php
$args = array( 'numberposts' => 10, 'order'=> 'ASC', 'orderby' => 'title' );
$postslist = get_posts( $args );
foreach ($postslist as $post) :  setup_postdata($post); ?> 
    <div>
        <?php the_date(); ?>
        <br />
        <?php the_title(); ?>   
        <?php the_excerpt(); ?>
    </div>
<?php endforeach; ?>
 

There's a guide for this precise case at the wordpress codex. See it here: I paste the code here because it's quite short, for more information go to the wordpress.org site.

<?php
$args = array( 'numberposts' => 10, 'order'=> 'ASC', 'orderby' => 'title' );
$postslist = get_posts( $args );
foreach ($postslist as $post) :  setup_postdata($post); ?> 
    <div>
        <?php the_date(); ?>
        <br />
        <?php the_title(); ?>   
        <?php the_excerpt(); ?>
    </div>
<?php endforeach; ?>

Wordpressfornisce unafunzioneper queltipo di richiesta: query_posts () .

query_posts () èilmodopiù semplicepermodificare la querypredefinita che WordPress utilizzaper visualizzarei post.Usa query_posts ()per visualizzare post diversi da quelli chenormalmente verrebbero visualizzatiin uno specifico URL.

Adesempio,nella homepagenormalmente vedrestigli ultimi 10 post.Se vuoimostrare solo 5post (enonti interessa impaginazione),puoi usare query_posts ()in questomodo:

query_posts ('posts_per_page=5');

Dopo avereseguito la query,puoi visualizzarei postnelmodo desiderato.

Wordpress provides a function for that kind of request: query_posts().

query_posts() is the easiest way to alter the default query that WordPress uses to display posts. Use query_posts() to display different posts than those that would normally show up at a specific URL.

For example, on the homepage, you would normally see the latest 10 posts. If you want to show only 5 posts (and don't care about pagination), you can use query_posts() like so:

query_posts( 'posts_per_page=5' );

Once you've performed the query, you can display the posts the way you want.

 <?php $the_query = new WP_Query( 'posts_per_page=3' ); 
while ($the_query -> have_posts()) : $the_query -> the_post();?>
<?php /*html in here etc*/ the_title(); ?>
<?php endwhile;wp_reset_postdata();?>
 

<?php $the_query = new WP_Query( 'posts_per_page=3' ); 
while ($the_query -> have_posts()) : $the_query -> the_post();?>
<?php /*html in here etc*/ the_title(); ?>
<?php endwhile;wp_reset_postdata();?>
