从 Wordpress 帖子中分离图像和文本内容 [英] separating the images and text content from Wordpress post

问题描述

我有一篇 Wordpress 帖子，我想将图片和文本内容分成 2 个单独的部分.我不能分别控制这两个元素.

I have a Wordpress post which I would like to strip the images and text content out in 2 separate parts. I wan't to be able to control both elements separately.

当前尝试

<?php
    $content = wpautop($content); // Add paragraph-tags
    $content = str_replace('<p></p>', '', $content); // remove empty paragraphs
    $content = preg_replace('/<p>\s*(<a .*>)?\s*(<img .* \/>)\s*(<\/a>)?\s*<\/p>/iU', '\1\2\3', $content); // remove paragraphs around img tags
    echo $content;
?> 

我能够在内容上放置

标签，但不确定如何取出元素并将每种类型带回来

I was able to put

tags on the content but ot sure how to take out elements and bring each type back

推荐答案

你可以做这样的事情来获取所有 img 标签:

You can do something like this to grab all img tags:

$document = new DOMDocument();
$document->loadHTML($content);
$images = $document->getElementsByTagName('img');
