HTML标记不在php if语句中显示

Question

I have a WordPress theme with a brief summary, with css styling, at the top of a post. This is wrapped in an if statement to only display if there is a summary.

Using the code below, the summary text displays, but the surrounding HTML markup is not included in the page source.

<?php if (get_smry_text($post)) { ?>
<div class="summaryWrap">
    <div class="sumText">
        <p><?php get_smry_text($post); ?></p>
     </div>
 </div>
 <?php } ?>

Can anyone offer a suggestion as to why this might be?

Answer 1

It is possible that get_smry_text() doesn't return any values.
Instead it echoes the content directly. If you are using this function you can do something like this:

<?php if ($smry = get_post_meta($post->ID, 'smry_text', true)) { ?>
<div class="summaryWrap">
    <div class="sumText">
        <p><? echo $smry; ?></p>
     </div>
 </div>
 <?php } ?>
