remove empty tags from wordpress shortcodes via a php functon

Question

Looking for a php function (non-jQuery or wpautop modification) approach to remove

from within wordpress.

I tried this but it does not w

Answer 1

What you need is a mix of jquery and php... that is the only working way
that i found to be working really well. i have tutorial on my site but
in order to keep stuff inhouse here goes

The jQuery:
include this in some JS file you already enqueue

jQuery(function($){
    $('div#removep > p').filter(function() {
        return $.trim($(this).text()) === '' && $(this).children().length == 0
    })
    .remove()
})

A shortcode you can later use:
in your functions.php or included file

function sght_removep( $atts, $content = null ) {return '<div id="removep">'.do_shortcode($content).'</div>';}
add_shortcode('removep', 'sght_removep');

Now you can wrap specific stuff like this:

[removep]
Some text i write directly in wordpress wysiwyg
<p></p> <-- this would get removed
[/removep]

This solution requires some know how but it works!
Hope this helps...

Answer 2

maybe a regex could work:

$string=preg_replace_('/<p>\s*</p>/', '', $string);

That should replace any <p></p> with nothing or just whitespaces in it to nothing, thus removing them.

When applying regex to HTML code it's a good idea to remove the \r\n of the HTML first, since they stop the regex from working.

Answer 3

add_filter('the_content', 'cleanup_shortcode_fix', 10);

I found that it works if you specify 10 as the priority; no other number will work.

Answer 4

You should increase the priority of the filter.

This should work

add_filter('the_content', 'cleanup_shortcode_fix', 1);

Answer 5

You can remove

Tag enter

<?php echo $post->post_content; ?>

instead of the_content()

Answer 6

Try inserting this code in your functions.php file:

remove_filter( 'the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop', 99 );
add_filter( 'the_content', 'shortcode_unautop', 100 );
