eliminar párrafos vacíos de the_content?

WordPressinsertará automáticamente lasetiquetas <p> y </p> que separan los saltos de contenido dentro de unapublicación opágina.Si,por alguna razón,desea onecesitaeliminarlos,puede utilizar cualquiera de los siguientesfragmentos de código.

Para deshabilitar completamenteelfiltro wpautop,puede usar:

 remove_filter('the_content', 'wpautop');
 

 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);

Tuveelmismoproblema quetú.Acabo de hacer una ... digamos ... una soluciónnomuybonita,perofunciona y hasta ahoraes la única solución quetengo.Agregué unapequeña línea de JavaScript.NecesitajQuery,peroestoy seguro de quepuede resolverlo sin él.

Esteesmi pequeño JS:

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

¡Estome funciona!

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!

Simplemente use CSS

 p:empty {
  display: none;
}
 

Simply use CSS

p:empty {
  display: none;
}

Sé queesto yaestámarcado como 'resuelto'pero solo como referencia,aquí hay unafunción que haceexactamente lo que quieres sintener que agregarningúnmarcado a laspublicaciones.Simplementepongaestoen functions.php de sutema:

 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);
}
 

Estoes deestaesencia: 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

Podríasejecutartufiltro antes de queese desagradable wpautop seenganche y semeta conelmarcado.

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

Deesamanera,ya habrá convertido lo quenecesitapara cuando seenganche,lo que ayudaen algunos casos.

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.

Elmismoenfoque que dos respuestas antes que yo, sino unaexpresión regular actualizada,porque la suyanofuncionóparamí.

laexpresión regular: /<p>(?:\s|&nbsp;)*?<\/p>/i (grupo sin captura quebusca cualquiernúmero deespaciosen blanco o   s dentro de laetiquetap,no distingueentremayúsculas yminúsculas.

 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);

Encontréestoextraño,peroen realidad llamar a the_content()insertarápárrafos de lamanera que usted describe.Si deseael código html,básicamente como loingresó (lomismo que "ver HTML" aleditar),use get_the_content() que devuelveel contenido sinformatoni etiquetas depárrafo.

Dado que lo devuelve,asegúrese de usar algo como:

echoget_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();

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
);}

Sitiene etiquetas <p> conespaciosen blancoen el contenido, ve atupublicación opágina yedítala sinestilo visual.

encontrará algo de   allí ... Elimínelo y lasetiquetas <p> vacías desaparecerán.

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.

Paratener solo contenido html sinetiquetas

 <?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; ?>
