从the_content删除空的段落？

WordPress将自动插入<p>和</p>标记,这些标记将内容分隔在帖子或页面中.如果出于某种原因想要或需要删除它们,则可以使用以下任一代码段.

要完全禁用wpautop过滤器,可以使用:

 remove_filter('the_content', 'wpautop');
 

如果您仍然希望此功能起作用,请尝试在过滤器中添加一个更高的优先级值,例如:

 add_filter('the_content', 'removeEmptyParagraphs',99999);
 

WordPress will automatically insert <p> and </p> tags which separate content breaks within a post or page. If, for some reason, you want or need to remove these, you can use either of the following code snippets.

To completely disable the wpautop filter, you can use:

remove_filter('the_content', 'wpautop');

If you still want this to function try adding a later priority value to your filter something like:

add_filter('the_content', 'removeEmptyParagraphs',99999);

我遇到了同样的问题.我只是做了一个...可以说...不是很漂亮的解决方案,但是它有效,到目前为止,这是我唯一的解决方案.我添加了一些JavaScript行.它需要jQuery,但我敢肯定,没有它就可以弄清楚.

这是我的小JS:

 $('p:empty').remove();
 

这对我有用！

I had the same problem you have. I just did a... let's say... not very beautiful solution, but it works and so far it's the only solution I have. I added a little JavaScript line. It needs jQuery, but I'm sure you can figure it out without.

This is my tiny JS:

$('p:empty').remove();

This works for me!

只需使用CSS

 p:empty {
  display: none;
}
 

Simply use CSS

p:empty {
  display: none;
}

我知道这已经被标记为"已解决",但是仅供参考,这是一个功能,可以完全满足您的需要,而无需在帖子中添加任何标记.只需将其放入主题的functions.php中即可:

 add_filter('the_content', 'remove_empty_p', 20, 1);
function remove_empty_p($content){
    $content = force_balance_tags($content);
    return preg_replace('#<p>\s*+(<br\s*/*>)?\s*</p>#i', '', $content);
}
 

这来自以下要点: https://gist.github.com/1668216

I know this is already marked 'solved' but just for reference, here's a function which does exactly what you want without having to add any markup to posts. Just put this in your theme's functions.php:

add_filter('the_content', 'remove_empty_p', 20, 1);
function remove_empty_p($content){
    $content = force_balance_tags($content);
    return preg_replace('#<p>\s*+(<br\s*/*>)?\s*</p>#i', '', $content);
}

This is from this gist: https://gist.github.com/1668216

您可以在该讨厌的wpautop挂接并弄乱标记之前运行过滤器.

 add_filter('the_content', 'qanda', 7 );
 

这样,您已经在挂钩时将所需的内容转换了,在某些情况下确实有帮助.

You could just run your filter before that nasty wpautop hooks on and messes with the markup.

add_filter('the_content', 'qanda', 7 );

That way, you've already converted what you need to by the time it hooks on, which does help in some cases.

与我面前的2个答案相同的方法, 但是更新了正则表达式,因为他对我不起作用.

正则表达式:/<p>(?:\s|&nbsp;)*?<\/p>/i (非捕获组在p标签内查找任意数量的空格或 ,所有情况均与情况无关.

 add_filter('the_content', function($content) {
    $content = force_balance_tags($content);
    return preg_replace('/<p>(?:\s|&nbsp;)*?<\/p>/i', '', $content);
}, 10, 1);
 

Same approach than 2 answers before me, but an updated regex, because his didn't work for me.

the regex: /<p>(?:\s|&nbsp;)*?<\/p>/i (non capture group looking for any number of either whitespace or  s inside p-tag, all case insenstive.

add_filter('the_content', function($content) {
    $content = force_balance_tags($content);
    return preg_replace('/<p>(?:\s|&nbsp;)*?<\/p>/i', '', $content);
}, 10, 1);

我发现这很奇怪,但是实际上调用the_content()将以您描述的方式插入段落.如果您想要html代码,基本上就像您输入的一样(与编辑时的"查看HTML"相同),则可以使用get_the_content()返回不带格式和段落标签的内容.

因为它返回了它,所以请确保使用类似以下内容的东西:

回声get_the_content();

另请参见: http://codex.wordpress.org/Function_Reference/get_the_content

I found this weird, but actually calling the_content() will insert paragraphs in the manner you describe. If you want the html code, basically like you entered it (the same as "view HTML" when editing), then use get_the_content() which returns the content without formatting and paragraph tags.

Since it returns it, make sure you use something like:

echo get_the_content();

这将递归删除字符串中的所有空html标记

 add_filter('the_content', 'remove_empty_tags_recursive', 20, 1);
function remove_empty_tags_recursive ($str, $repto = NULL) {
         $str = force_balance_tags($str);
         //** Return if string not given or empty.
         if (!is_string ($str)
         || trim ($str) == '')
        return $str;

        //** Recursive empty HTML tags.
       return preg_replace (

              //** Pattern written by Junaid Atari.
              '/<([^<\/>]*)>([\s]*?|(?R))<\/\1>/imsU',

             //** Replace with nothing if string empty.
             !is_string ($repto) ? '' : $repto,

            //** Source string
           $str
);}
 

模式取自 http://codesnap.blogspot.in/2011/04/recursively-remove-empty-html-tags.html

This will recursively remove all the empty html tags from the string

add_filter('the_content', 'remove_empty_tags_recursive', 20, 1);
function remove_empty_tags_recursive ($str, $repto = NULL) {
         $str = force_balance_tags($str);
         //** Return if string not given or empty.
         if (!is_string ($str)
         || trim ($str) == '')
        return $str;

        //** Recursive empty HTML tags.
       return preg_replace (

              //** Pattern written by Junaid Atari.
              '/<([^<\/>]*)>([\s]*?|(?R))<\/\1>/imsU',

             //** Replace with nothing if string empty.
             !is_string ($repto) ? '' : $repto,

            //** Source string
           $str
);}

Pattern is taken from http://codesnap.blogspot.in/2011/04/recursively-remove-empty-html-tags.html

如果您的<p>标记的内容中带有空格, 转到您的帖子或页面,以非视觉风格对其进行编辑.

您会在其中找到一些 . 删除它,空的<p>标签将消失.

If you have <p> tags with whitespace in the content, go to your post or page an edit it not in visual style.

you would be find some   in there.. Delete it and the empty <p> tags will disappear.

为了只包含不带

 <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php the_title(); ?>
<?php echo $post->post_content; ?>
<?php endwhile; endif; ?>
 

In order to have only html content without

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php the_title(); ?>
<?php echo $post->post_content; ?>
<?php endwhile; endif; ?>
