WordPress的从内容中删除短代码

问题描述

在执行 the_content（）之前，是否可以从内容中删除图库简码？我搜索了codex，发现 remove_shortcode（$ tag），但是它们没有显示任何示例。

/ p>

  function remove_gallery（$ content）{
 $ content。= remove_shortcode（'[gallery]'）; 
返回$ content; 
} 
 add_filter（'the_content'，'remove_gallery'，6）; 
  

不起作用..

更新：

我可以使用下面的代码取消注册短代码，但它也会删除内容

 函数remove_gallery（$ content）{
 return remove_shortcode（'gallery'，$ content）; 
} 
 add_filter（'the_content'，'remove_gallery'，6）; 
  

解决方案

奇怪。 remove_shortcode（）不需要第二个参数。

您将返回remove_shortcode函数的真或假返回值，而不是移除短码的内容。

  remove_shortcode（ '画廊'）; 
返回$ content; 
  

或者直接放入

  remove_shortcode（'gallery'）; 
  

在您的functions.php文件中。以前的海报建议包括[]的，我猜是错误的。

Is it possible to remove the gallery shortcode from the content before when the_content() is executed? I searched codex and found remove_shortcode( $tag ) but they show no examples.

I tried adding to functions

function remove_gallery($content) {
    $content .= remove_shortcode('[gallery]');
    return $content;
}
add_filter( 'the_content', 'remove_gallery', 6);

It doesnt work..

Update:

I was able to unregister the shortcode using the code below, but it also removes the content

function remove_gallery($content) {
    return remove_shortcode('gallery', $content);
}
add_filter( 'the_content', 'remove_gallery', 6);

解决方案

Strange. remove_shortcode (codex link) doesn't take a second argument.

You're returning either the true or false return of the remove_shortcode function, not the content with the shortcode removed.

Try either something like this in that second version of your function up there:

remove_shortcode('gallery');
return $content;

Or just put

 remove_shortcode('gallery');

In your functions.php file. The previous poster suggested including the [ ]'s, which I guess is wrong.
