    wordpress snippet : PHP

    function enable_more_buttons($buttons) {
      $buttons[] = 'sub';

    (text translated by the program)
    Thank you for providing this code, but no need to repeat the array code, simply separate the items in the array

    function enable_more_buttons($buttons) {
    $buttons[] = ‘sub , sup’;
    return $buttons;
    add_filter(“mce_buttons_2”, “enable_more_buttons”);

    • This is true, I just find this method easier to read. Thanks for the input though people will find this very useful.
