用于修改最终 html 输出的 WordPress 过滤器 [英] WordPress filter to modify final html output
问题描述
WordPress 具有强大的过滤器支持，可以获取各种特定的内容位并在输出之前对其进行修改.就像 the_content 过滤器一样，它允许您在将帖子输出到屏幕之前访问该帖子的标记.
WordPress has great filter support for getting at all sorts of specific bits of content and modifying it before output. Like the_content filter, which lets you access the markup for a post before it's output to the screen.
我正在尝试找到一个包罗万象的过滤器，它使我能够在输出之前完全修改最终标记.
I'm trying to find a catch-all filter that gives me one last crack at modifying the final markup in its entirety before output.
我已多次浏览过滤器列表，但没有任何内容让我感到惊讶:https://codex.wordpress.org/Plugin_API/Filter_Reference
I've browsed the list of filters a number of times, but nothing jumps out at me: https://codex.wordpress.org/Plugin_API/Filter_Reference
有人知道吗?
推荐答案
AFAIK，没有钩子，因为主题使用 HTML 不会被 WordPress 处理.
AFAIK, there is no hook for this, since the themes uses HTML which won't be processed by WordPress.
但是，您可以使用输出缓冲来捕获最终的 HTML:
You could, however, use output buffering to catch the final HTML:
<?php
// example from php.net
function callback($buffer) {
// replace all the apples with oranges
return (str_replace("apples", "oranges", $buffer));
}
ob_start("callback");
?>
<html><body>
<p>It's like comparing apples to oranges.</p>
</body></html>
<?php ob_end_flush(); ?>
/* output:
<html><body>
<p>It's like comparing oranges to oranges.</p>
</body></html>
*/
