从 get_the_content() 中删除图像也会删除 <p>标签 [英] strip images from get_the_content() removes also <p> tags

问题描述

我正在尝试使用以下代码从 get_the_content() 中删除所有图像和周围的 标记:

I'm trying to strip all images and the surrounding <a> tag from get_the_content() with this piece of code:

<?php
$content = get_the_content();
$postOutput = preg_replace(array('{<a[^>]*><img[^>]+.}','{></a>}'),'', $content);
echo $postOutput;
?>

这很好用，除了段落周围没有

标签.
1. 使用get_the_content()时是否正常?
2. 我怎样才能将它们添加到我的结果中?
3. 还是我的正则表达式错了?

That works fine, except there are no <p> tags around the paragraphs.
1. Is this normal when using get_the_content()?
2. and how could I add them to my result?
3. Or is my regex wrong?

推荐答案

好的，我会回答我自己的问题:

Okay I will answer my own questions:

1. 是的，在 get_the_content() 上没有

   是正常的，谢谢@s_ha_dum

2. 要添加 <p>，我需要将内容过滤器应用为 此处提到(向下滚动到替代用法").
3. 正则表达式没有错，但是对 html 进行正则表达式非常脏.谢谢@MarcB

1. Yes it is normal that there are no <p> on get_the_content() thanks @s_ha_dum
2. To add the <p> I need to apply the content filter as mentioned here (scroll down to "Alternative Usage").
3. The regex is not wrong but it is pretty dirty to regex the html. Thanks @MarcB

查看导致以下代码的新问题 这里

See the new question that lead to the following code here

$dom = new DOMDocument;
$dom->loadHTML(get_the_content());
$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//img|//a[img]');
foreach($nodes as $node) {
    $node->parentNode->removeChild($node);
}
$no_image_content = $dom->saveHTML();
$no_image_content = apply_filters('the_content', $no_image_content);
$no_image_content = str_replace(']]>', ']]>', $no_image_content);
echo $no_image_content;
