How do i use fontawesome icons in TinyMce editor?

by

I’m trying to add a youtube button in TinyMce editor.

here is a recent-posts.js file which is in the js folder of the theme directory.

(function() {
   tinymce.create('tinymce.plugins.buttons', {
      init : function(ed, url) {

         //for recent post button
         ed.addButton('recentposts', {
            title : 'Recent posts',
            image : url + '/youtube.png',
            onclick : function() {
               var posts = prompt("Number of posts", "");
               var text = prompt("List Heading", "");

               if (text != null && text != ''){
                  if (posts != null && posts != '')
                     ed.execCommand('mceInsertContent', false, '[recent-posts posts="'+posts+'"]'+text+'[/recent-posts]');
                  else
                     ed.execCommand('mceInsertContent', false, '[recent-posts]'+text+'[/recent-posts]');
               }
               else{
                  if (posts != null && posts != '')
                     ed.execCommand('mceInsertContent', false, '[recent-posts posts="'+posts+'"]');
                  else
                     ed.execCommand('mceInsertContent', false, '[recent-posts]');
               }
            }
         });


         //for youtube video
          ed.addButton('youtube', {
            title : 'YouTube',
            text: 'YouTube',          
            onclick : function() {
               var id = prompt("Video id", "");
               var text = prompt("Video Heading", "");

               if (text != null && text != ''){
                  if (id != null && id != '')
                     ed.execCommand('mceInsertContent', false, '[yt id="'+id+'"]'+text+'[/yt]');
               }
               else{
                  if (id != null && id != '')
                     ed.execCommand('mceInsertContent', false, '[yt posts="'+id+'"]');
               }
            }
         });

      },
      createControl : function(n, cm) {
         return null;
      },
      getInfo : function() {
         return {
            longname : "me The Most Brilliant",
            author : 'me',
            authorurl : 'http://www.google.com',
            infourl : 'http://www.google.com',
            version : "1.0"
         };
      }
   });
   tinymce.PluginManager.add('buttons', tinymce.plugins.buttons);
})();

code in functions.php is

function register_button( $buttons ) {
   array_push( $buttons,"recentposts", "youtube" );
   return $buttons;
}

function add_plugin( $plugin_array ) {
   $plugin_array['buttons'] = get_template_directory_uri() . '/js/recent-posts.js';
   return $plugin_array;
}

function my_recent_posts_button() {

   if ( ! current_user_can('edit_posts') && ! current_user_can('edit_pages') ) {
      return;
   }

   if ( get_user_option('rich_editing') == 'true' ) {
      add_filter( 'mce_external_plugins', 'add_plugin' );
      add_filter( 'mce_buttons', 'register_button' );
   }

}

add_action('init', 'my_recent_posts_button');

In place of image : url+'/youtube.png' i’m trying to use text :'<i class="fa fa-camera-retro"></i>'

But in text editor insted of font awesome icon , it is just showing as a text as it is.
Where should i place the font awesome file and how should i call it and how to use it in TinyMce?

You wouldn’t be able to add a FontAwesome icon by passing it directly to the ed.addButton(); method unfortunately.

You can try a workaround however. If you leave the image : url+'/youtube.png' parameter out of the method then it will automatically create an empty <span> with the class of mceIcon & another class of mce_[plugin_name].

You can then use CSS to style that <span> element however you would like.

You can use FontAwesome directly in your CSS now, something like this (make sure you change .mce_[plugin_name] place-hoder class used here to your actual class):

span.mce_[plugin_name] {
    position: relative;
}

span.mce_[plugin_name]:before {
    content: "\f166"; /* Value for the Youtube icon*/
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    text-decoration: inherit;
/*--adjust as necessary--*/
    color: #000;
    font-size: 18px;
    padding-right: 0.5em;
    position: absolute;
    top: 10px;
    left: 0;
}

UPDATE

Here is how I load my FontAwesome CSS file. I have adapted to load for the admin area for what you need to do however. I call it from the BootStrap CDN, but you could download the CSS file and load it from your theme or plugin folder using the same admin_enqueue_scripts(); function.

// Load Font Awesome
function royal_enqueue_awesome() {
    wp_enqueue_style( 'prefix-font-awesome', '//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.min.css', array(), '4.0.3' );
}

add_action( 'admin_enqueue_scripts', 'royal_enqueue_awesome' );
