想知道是否有人知道在使用：get\\u post\\u custom时如何获取要渲染的切换短代码

<?php
    $post_customs = get_post_custom();
    //$post_customs = the_sub_field(\'project_items\');
    if(isset($post_customs["project_items"]) && count($post_customs["project_items"]) > 0) {
        $project_items = $post_customs["project_items"][0];
        $projectItems = explode(":",$project_items);
?>
            <?php if(count($projectItems) > 1) {
                $totalProjectItems = $projectItems[1];
                for($i = 0; $i < $totalProjectItems; $i++) {
            ?>

            <?php $pro_item_post = get_post($post_customs["project_items_".$i."_choose_project_item"][0]); ?>

调用内容时使用：

            <aside class="one_half last">

                <?php echo $post_customs["project_items_".$i."_edit_proposal_item"][0]; ?>

            </aside><!--/.one_half -->

这会呈现出内容区域内的短代码，即：“[切换标题=“测试”]内容”，而不是将其实际呈现为切换。任何帮助都将不胜感激。

echo do_shortcode($post_customs["project_items_".$i."_edit_proposal_item"][0]);
