I'm trying to Clean up pasted text in WordPress and so I've decided to followed the instructions of this tutorial.

It seems simple just to add a filter on before_wp_tiny_mce and add a setting to clean the text.

My issue is that tiny_mce_before_init is never triggered. I can see these hooks trigger : before_wp_tiny_mce, wp_tiny_mce_init, after_wp_tiny_mce but never tiny_mce_before_init.

I've looked everywhere nothing has removed the filter, no extension to replace tinymce.

If anyone has an idea ?

Edit, here is the code (i've tried to put it in the function.php of my child themes where others hooks are and working) :

add_filter('tiny_mce_before_init','configure_tinymce');

/**
 * Customize TinyMCE's configuration
 *
 * @param   array
 * @return  array
 */
function configure_tinymce($in) {
  $in['paste_preprocess'] = "function(plugin, args){
    // Strip all HTML tags except those we have whitelisted
    var whitelist = 'p,span,b,strong,i,em,h3,h4,h5,h6,ul,li,ol';
    var stripped = jQuery('<div>' + args.content + '</div>');
    var els = stripped.find('*').not(whitelist);
    for (var i = els.length - 1; i >= 0; i--) {
      var e = els[i];
      jQuery(e).replaceWith(e.innerHTML);
    }
    // Strip all class and id attributes
    stripped.find('*').removeAttr('id').removeAttr('class');
    // Return the clean HTML
    args.content = stripped.html();
  }";
  return $in;
}

    There's no code in your question, can you edit your question to add it? Also where is the code? The location and when it loads is important – Tom J Nowell Jan 26 '18 at 15:59

Looking at the contents of class-wp-editor.php, it looks like tiny_mce_before only triggers if you are not using the Teeny version of the editor:

/*
 * For people who really REALLY know what they're doing with TinyMCE
 * You can modify $mceInit to add, remove, change elements of the config
 * before tinyMCE.init. Setting "valid_elements", "invalid_elements"
 * and "extended_valid_elements" can be done through this filter. Best
 * is to use the default cleanup by not specifying valid_elements,
 * as TinyMCE checks against the full set of HTML 5.0 elements and attributes.
 */
if ( $set['teeny'] ) {

    /**
     * Filters the teenyMCE config before init.
     *
     * @since 2.7.0
     *
     * @param array  $mceInit   An array with teenyMCE config.
     * @param string $editor_id Unique editor identifier, e.g. 'content'.
     */
    $mceInit = apply_filters( 'teeny_mce_before_init', $mceInit, $editor_id );
} else {

    /**
     * Filters the TinyMCE config before init.
     *
     * @since 2.5.0
     *
     * @param array  $mceInit   An array with TinyMCE config.
     * @param string $editor_id Unique editor identifier, e.g. 'content'.
     */
    $mceInit = apply_filters( 'tiny_mce_before_init', $mceInit, $editor_id );
}

If the config can work for both Tiny and Teeny, you could hook on both filters to modify the configuration.

  • thanks ! i'll try it and let you know, i did notice the teeny/tiny settings but i was very far to think that changes hooks logical too ... – Aliiiiiiii Jan 28 '18 at 15:14
