My users post snippets code in comments. I created a shortcode for this :

function post_codigo($atts,$content=""){

        return '<code>'.$content.'</code>';


Problem is that html gets filtered before its wrapped into the code tags.

I think that if i can get the shortcode run before filters then i can use

function pre_esc_html($content) {
  return preg_replace_callback(
      'return $i[1].esc_html($i[2]).$i[3];'


that i found around here. What you think?

UPDATED: Ok now i changed my shortcode to:

 function post_codigo($atts,$content=""){

            return '<code>'.esc_html($content).'</code>';


But it still adding

breaks and breaking the whole code into several tags

You can filter the array $no_texturize_shortcodes, which is a collection of shortcodes that are excluded from wptexturize. If you do this, everything within [codigo] shortcode tags will not be texturized:

add_filter( 'no_texturize_shortcodes', 'no_texturize_codigo_shortcode' );

function no_texturize_codigo_shortcode( $excluded_shortcodes ) {
    $excluded_shortcodes[] = 'codigo';
    return $excluded_shortcodes;

    I tried this but im getting same result. If you check source of masquewordpress.com/ayuda/… you will see that javascript is still as javascript. I need to scape all text in my shortcode function?

  • hmmm. I don't really see it. It seems to look OK to me. Are you still having issues with it? Nov 7, 2011 at 22:11
  • Nope, i only changed the <code> tag to <pre> and the problem solved. Thanks for the help

The no_texturize_shortcodes filter did nothing for me, as the content inside the shortcode would have already been filtered by wpautop() and any other filters hooked to the the_content. I resorted to changing the filter order of do_shortcode in relation to the_content, so that I can be certain it runs first of the two. Here's how:

remove_filter('the_content', 'do_shortcode', 11); // AFTER wpautop()
add_filter('the_content', 'do_shortcode', 9); // BEFORE wpautop()

This seems to work out fairly well, but as this is quite an extensive alteration to the way WordPress handles its text/html conversion I'd recommend you use it with caution. The more plugins/shortcodes you are using the more likely you are to run in to trouble relating to this change I'd guess.


Is your theme using comment_text() to display your visitor's comments?

if so try changing:

<?php comment_text(); ?>


<?php echo do_shortcode(apply_filters('comment_text', get_comment_text())); ?>

This will apply any "comment_text" filters to the comment text, before it will apply the shortcode.

This should be done in your theme templates wherever comments are displayed.

  • Thanks but i need the other way around. The shortcode should run before filter so then i can avoid filtering inside the shortcode.
