Question

好的，所以我在当前主题中有这段代码：

<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; ?>

我需要做的是在“the_content”周围添加一个DIV环绕，当且仅当$ project_photos选择器处于活动状态时，不是PHP开发人员这是我提出的但是它不起作用：

<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; ?>

如果有人能就如何实现这一目标提供一些指导，我将非常感激。

提前致谢。

你可以尝试一下吗？

 <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; ?>
