好吧，我当前的主题中有这段代码:
<div class="content_block">
<?php the_content(); ?>
<div class="<?php echo $left_block; ?>">
<?php $project_photos = get_post_meta( get_the_ID(), 'project_photo_photo' );
if ( $project_photos ) : ?>
<div class="grid_gallery clearfix">
<?php foreach( $project_photos as $project_photo ) { ?>
<figure class="gallery_item featured-thumbnail thumbnail single-gallery-item">
<a href="/brv2/wp-content/files_mf/<?php echo $project_photo; ?>" class="image-wrap" rel="prettyPhoto[gallery]">
<img class="project_photo_photo" width="260" src="/brv2/wp-content/files_mf/<?php echo $project_photo; ?>" alt="<?php the_title(); ?>" />
<span class="zoom-icon"></span>
</a>
</figure>
<?php } ?>
<!--END .slider -->
</div>
<?php endif; ?>
我需要做的是当且仅当 $project_photos 选择器处于事件状态时添加一个 DIV 围绕“the_content”，而不是 PHP 开发人员，这是我想出的方法，但它不起作用:
<div class="content_block">
<?php if ( $project_photos() ) {
echo '<div class="project_description">';
the_content();
echo '</div>';
} else {
the_content();
} ?>
<div class="<?php echo $left_block; ?>">
<?php $project_photos = get_post_meta( get_the_ID(), 'project_photo_photo' );
if ( $project_photos ) : ?>
<div class="grid_gallery clearfix">
<?php foreach( $project_photos as $project_photo ) { ?>
<figure class="gallery_item featured-thumbnail thumbnail single-gallery-item">
<a href="/brv2/wp-content/files_mf/<?php echo $project_photo; ?>" class="image-wrap" rel="prettyPhoto[gallery]">
<img class="project_photo_photo" width="260" src="/brv2/wp-content/files_mf/<?php echo $project_photo; ?>" alt="<?php the_title(); ?>" />
<span class="zoom-icon"></span>
</a>
</figure>
<?php } ?>
<!--END .slider -->
</div>
<?php endif; ?>
如果有人可以提供一些关于我如何实现这一目标的指导，我将非常感激。
提前致谢。
最佳答案
你能尝试一下吗？
<div class="content_block">
<?php
$project_photos = get_post_meta( get_the_ID(), 'project_photo_photo' );
if ( $project_photos ) {
echo '<div class="project_description">';
the_content();
echo '</div>';
} else {
the_content();
} ?>
<div class="<?php echo $left_block; ?>">
<?php
if ( $project_photos ) : ?>
<div class="grid_gallery clearfix">
<?php foreach( $project_photos as $project_photo ) { ?>
<figure class="gallery_item featured-thumbnail thumbnail single-gallery-item">
<a href="/brv2/wp-content/files_mf/<?php echo $project_photo; ?>" class="image-wrap" rel="prettyPhoto[gallery]">
<img class="project_photo_photo" width="260" src="/brv2/wp-content/files_mf/<?php echo $project_photo; ?>" alt="<?php the_title(); ?>" />
<span class="zoom-icon"></span>
</a>
</figure>
<?php } ?>
<!--END .slider -->
</div>
<?php endif; ?>
