我在WordPress站点的父页面上有下面的代码。该页从子页中提取内容，以摘要格式显示在其上。我缺少的是如何从子页面拉特色图像URL的代码。标题和内容都很好。什么好主意吗?
<?php
$mypages = get_pages( array( 'child_of' => $post->ID, 'sort_column' => 'post_date', 'sort_order' => 'desc' ) );
foreach( $mypages as $page ) {
$content = $page->post_content;
if ( ! $content ) // Check for empty page
continue;
$content = apply_filters( 'the_content', $content );
?>
<h2><a href="<?php echo get_page_link( $page->ID ); ?>"><?php echo $page->post_title; ?></a></h2>
<div class="entry"><?php echo $content; ?></div>
<?php
}
?>
只需添加the_post_thumbnail();即可检索特征图像。有关进一步定制，请参阅此特色图像指南
所以修改后的代码是:
<?php
$mypages = get_pages( array( 'child_of' => $post->ID, 'sort_column' => 'post_date', 'sort_order' => 'desc' ) );
foreach( $mypages as $page ) {
$content = $page->post_content;
if ( ! $content ) // Check for empty page
continue;
$content = apply_filters( 'the_content', $content );
?>
<h2><a href="<?php echo get_page_link( $page->ID ); ?>"><?php echo $page->post_title; ?></a></h2>
<?php the_post_thumbnail(); ?> // Gets the featured image
<div class="entry"><?php echo $content; ?></div>
<?php
}
?>
