奇怪的事情:
代码:
<div class="container">
<div class="row">
<?php
$args = array( 'numberposts' => '3' );
$recent_posts = wp_get_recent_posts( $args );
foreach($recent_posts as $post)
{
?><div class="col-md-4">
<div class="row">
<a href="<?php echo get_the_permalink($post['ID']); ?>">
<?php echo $post['post_title']; ?>
</a>
</div>
<div class="row">
<?php echo get_the_post_thumbnail($post['ID'], 'thumbnail'); ?>
<?php
$my_excerpt = get_the_excerpt($post['ID']);
if ( '' != $my_excerpt ) {
// Some string manipulation performed
}
echo $my_excerpt // Outputs the processed value to the page
?>
</div>
</div><?php
}
wp_reset_query();
?>
</div>
</div>
</br>
</br>
<div class="container">
<div class="row">
<?php
$args = array( 'numberposts' => '3' );
$recent_posts = wp_get_recent_posts( $args );
foreach($recent_posts as $post) { ?>
<div class="col-md-4">
<div class="row">
<a href="<?php echo get_the_permalink($post['ID']) ?>">
<?php echo $post['post_title'] ?>
</a>
</div>
<div class="row">
<?php echo get_the_post_thumbnail($post['ID'], 'thumbnail'); ?>
</div>
<div class="row">
<?php
$my_excerpt = get_the_excerpt($post['ID']);
if ( '' != $my_excerpt ) {
// Some string manipulation performed
}
echo $my_excerpt // Outputs the processed value to the page
?>
</div>
</div>
<?php
}
wp_reset_query();
?>
</div>
</div>
当我更改代码的位置并删除 Headers 和缩略图时,代码运行良好:
<?php
$args = array( 'numberposts' => '3' );
$recent_posts = wp_get_recent_posts( $args );
foreach($recent_posts as $post) { ?>
<?php
$my_excerpt = get_the_excerpt($post['ID']);
if ( '' != $my_excerpt ) {
// Some string manipulation performed
}
echo $my_excerpt // Outputs the processed value to the page
?>
</div>
</div>
<?php
}
wp_reset_query();
?>
我在我的wordpress / woocommerce页面中调用了最近的帖子,但是当我打电话给摘录时,它并没有弄明白发生了什么 . 当我用一个简单的单词更改"echo $my_excerpt"时,它可以工作 . 问题应该是我把内容放在一个数组中 . 您已经按照文档查看了:https://codex.wordpress.org/Function_Reference/get_the_excerpt
示例get_the_excerpt()可用于在变量中检索和存储值,而无需将其输出到页面 .
<?php
$my_excerpt = get_the_excerpt();
if ( '' != $my_excerpt ) {
// Some string manipulation performed
}
echo $my_excerpt; // Outputs the processed value to the page
?>
我的代码:
<?php
$args = array( 'numberposts' => '3' );
$recent_posts = wp_get_recent_posts( $args );
foreach($recent_posts as $post) { ?>
<div class="col-md-4">
<div class="row">
<a href="<?php echo get_permalink($post['ID']) ?>">
<?php echo $post['post_title'] ?>
</a>
</div>
<div class="row">
<?php echo get_the_post_thumbnail($post['ID'], 'thumbnail'); ?>
<?php
$my_excerpt = get_the_excerpt();
if ( '' != $my_excerpt ) {
// Some string manipulation performed
}
echo $my_excerpt // Outputs the processed value to the page
?>
</div>
</div>
<?php
}
wp_reset_query();
?>
</div>
</div>

Edit: 我已经改变了你的代码尝试使用这个 .
试试这个 . 我已经为你的摘录提供了帖子ID .
好吧,经过大量的选择,测试,反馈和研究,我找到了一种方法来实现它 .
谢谢大家!
