Change HTML output using the included Filter

    I’m struggling to see how to correctly implement your included filter.

    I’m simply trying to change the output of the HTML to wrap the title in a span tag.

    Currently I’m trying to do that like this:

    // Custom Document Display
function dg_doc_icon( $icon, $id ){

   return '<div class="document-icon"><a href="'.$icon->link.'">awesome'.$icon.'<span class="document-title">'.get_the_title($icon).'</span></a></div>';
}
add_filter( 'dg_doc_icon', 'dg_doc_icon', null, 2 );

    Can you please explain how to access the URL, icon, and title? Thanks.

    Hi jedifunk,

    The dg_dog_icon filter returns the string representation of the document icon as the first value and the ID of the document as the second value.

    Because of this, you will most likely need to use regular expressions to generate the output you want. The example I give in the plugin installation instructions is this:

    function dg_doc_icon( $icon, $id ){
   $ptn = '/(.* href=")([^"]+)(".*)/s';

   if( !preg_match( $ptn, $icon, $matches ) || count( $matches ) !== 4 )
      return $icon;

   if( strpos( $matches[2], '?' ) !== false )
      return "{$matches[1]}{$matches[2]}&rid=".get_the_ID().$matches[3];

   return "{$matches[1]}{$matches[2]}?rid=".get_the_ID().$matches[3];
}
add_filter( 'dg_doc_icon', 'dg_doc_icon', null, 2 );

    In here we append a GET value to the end of the URL.

    This string/regex setup is not ideal and I hope to improve it in the future, but as of now that is the answer.

    Please let me know if you need further assistance!
