Question

我需要在WordPress网站外部创建最近发布的帖子部分，但结果不正确（请参阅图片）。我使用了这个PHP代码：

// elsewhere in code...
require "wp-load.php";

// the code that is generating the recent posts section
$posts = get_posts( array( 'posts_per_page' => 1 ) );
$recent_posts = wp_get_recent_posts(array('numberposts' => 7 ) );
foreach ($posts as $_post) {
    foreach($recent_posts as $post) {
        if ( has_post_thumbnail( $_post->ID ) ) {
            echo '<div class="owl-item">';
                echo '<figure class="blog-item-container">';
                    echo '<span class="blog-item-img">';
                        echo get_the_post_thumbnail( $_post->ID, array(480, 305) );
                    echo '</span>';
                    echo '<figcaption>';
                        echo '<h3><a href="', get_permalink($post['ID']), '">', $post['post_title'], '</a></h3>';
                    echo '</figcaption>';
                echo '</figure>';
            echo '</div>';
        }
    }
}

PHP code result

我希望得到最近每篇特定帖子的图片。这个结果给了我正确的最近帖子，但所有帖子的图像都相同。为什么图像一样？

以下是对您的代码的一些评论，希望能够解释出现了什么问题，或者帮助您了解它的底部：

// Here you are getting ONE post for some reason, and putting it in the $posts variable
$posts = get_posts( array( 'posts_per_page' => 1 ) );
// Here you are getting 7 posts, and putting in the $recent_posts variable
$recent_posts = wp_get_recent_posts(array('numberposts' => 7 ) );
// Here you are "looping" over the ONE post and putting into $_post variable.
// So here, $_post is made to reference the single most recent post
foreach ($posts as $_post) {
    // Here, you are "looping" over the 7 recent posts, putting into $post variable
    foreach($recent_posts as $post) {
        // Here you ask if the ONE most recent post ($_post) has a featured image.  
        // I doubt this is what you actually want, as this will
        // be run for all 7 recent posts, but is only referencing
        // the single ONE post
        if ( has_post_thumbnail( $_post->ID ) ) {
            echo '<div class="owl-item">';
                echo '<figure class="blog-item-container">';
                    echo '<span class="blog-item-img">';
                        // here you are displaying the image for the ONE post, not the 7 most recent posts
                        echo get_the_post_thumbnail( $_post->ID, array(480, 305) );
                    echo '</span>';
                    echo '<figcaption>';
                        // Here you are referencing the title, link, etc.
                        // for the 7 most recent posts
                        echo '<h3><a href="', get_permalink($post['ID']), '">', $post['post_title'], '</a></h3>';
                    echo '</figcaption>';
                echo '</figure>';
            echo '</div>';
        }
    }
}

因此，考虑到您最近发布的帖子＆＃34;以及您的评论不正确以显示所有相同的精选图片，我怀疑代码应该看起来像这样（注意：你可以删除所有注释的代码，我把它留在这里解释变化是什么）：

// remove this - no need for the single most recent post
// $posts = get_posts( array( 'posts_per_page' => 1 ) );
$recent_posts = wp_get_recent_posts(array('numberposts' => 7 ) );
// remove this - don't loop over the single most recent post
// foreach ($posts as $_post) {
foreach($recent_posts as $post) {
    // change this to $post['ID'] (from $_post->ID)
    if ( has_post_thumbnail( $post['ID'] ) ) {
        echo '<div class="owl-item">';
            echo '<figure class="blog-item-container">';
                echo '<span class="blog-item-img">';
                    // change this to $post['ID'] (from $_post->ID)
                    echo get_the_post_thumbnail( $post['ID'], array(480, 305) );
                echo '</span>';
                echo '<figcaption>';
                    echo '<h3><a href="', get_permalink($post['ID']), '">', $post['post_title'], '</a></h3>';
                echo '</figcaption>';
            echo '</figure>';
        echo '</div>';
    }
}
// remove this, since we are removing the loop
// }

使用wordpress外的图像为最近的帖子创建一个循环
