如何在静态页面中显示最后3个帖子（最近的帖子）？

我通常使用这种方法:

错误的方法

 <?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; ?>
 

在@swissspidy的帮助下正确的方法是这样的:

 <?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; ?>

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; ?>

这取决于您要做什么.如果要创建"帖子页面"(换句话说,创建一个新页面模板文件),则可以在该页面上创建辅助循环.

抄本有一个示例,这是另一个非常精简的示例.

 <?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 */ ?>
 

如果您正在寻找可放入任何页面的内容,最好的解决方案是短代码.您将需要创建一个短代码,以获取多个帖子并将其返回到列表中(或您想要的任何内容).一个例子:

 <?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;
}
 

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;
}

在wordpress Codex上有关于这种精确情况的指南.在此处查看: 我将代码粘贴到此处,因为它很短,有关更多信息,请访问wordpress.org网站.

 <?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; ?>

Wordpress为此类请求提供了一个功能: query_posts().

query_posts()是更改默认查询的最简单方法 WordPress用于显示帖子.使用query_posts()显示 与通常显示在特定位置的帖子不同的帖子 网址.

例如,在首页上,您通常会看到最新的10 帖子.如果您只想显示5个帖子(并且不在乎 分页),您可以像这样使用query_posts():

query_posts('posts_per_page=5');

执行查询后,您可以按所需方式显示帖子.

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();?>
