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

   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;


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' );

  • and fontawesome's youtube icon comes using <i class="fa fa-youtube"></i>. How do i use this in css? Jul 1, 2014 at 14:43
  • What you are doing in your code above is adding your own TinyMCE plugin - I'm not referring to using a WordPress plugin :-) I suggest looking at this tutorial to get a good overview of the process as well, might be helpful :-)

    Try this as you were using the wrong action and loading FontAwesome to the website not the Dashboard as you need to... function thought_script(){ wp_enqueue_style('fontawesome-style', get_template_directory_uri().'/font-awesome/css/font-awesome.min.css'); } add_action('admin_enqueue_scripts', 'thought_script');

    Now i figured it out, it is not span element it is i element which will come if no text or image is specified. so i just needed to target i.mce-i-youtube class, which is different as you mentioned. I was looking for span element. ty for your help and time. Jul 1, 2014 at 19:06

I tested the following on WordPress 4.6.1

I originally looked up this process to help create a button that would produce a shortcode. Based on some various posts, I originally used the following addButton parameters within my javascript file to decor my TINYMCE button...

ed.addButton('wpse72394_button', { title: 'title of my button', cmd: 'wpse72394_inser', image: url + '/path/to/image.png' });

...But I didn't want to create a new button from scratch or just a text label. I instead wanted to reference an existing icon in WordPress. I discovered that I could easily swap out the image: parameter for an icon: parameter like so...

ed.addButton('wpse72394_button', { title: 'Insert shortcode', cmd: 'wpse72394_insert_shortcode', icon: 'wp_code' });

Within WordPress, if you look within


you will discover various options like...


I don't believe these are fontawesome icons, but they are close enough for me in getting the job done without adding additional css or cdn link references.


Here is a greatly simple solution for this.

Firstly add the FontAwesome library to WordPress Backend by creating and adding it to admin_init

function fontawesome_dashboard() {
   wp_enqueue_style('fontawesome', 'https://use.fontawesome.com/releases/v5.1.1/css/all.css'); 

add_action('admin_head', 'fontawesome_dashboard', 11);

Then on you javascript file:

ed.addButton('recentposts', {
            title : 'Recent posts',
            icon: ' fa fa-camera-retro', // notice a space before the 'fa'

This kind of hack worked for me. I am sure it will work for you as well :)

  • This works great (running WP 5.7.2 and FontAwesome 5.15.1). Just make sure, to pay attention to the SPACE before the first class LOL
