By default, the WordPress user description is plain text. The following PHP code adds the WYSIWYG editor TinyMCE to display the author description in the user profile.
Simply add the code to function.php in your template:
function.php
class CustomUserProfile { private $tinymceOptions = array( 'teeny' => true, 'quicktags' => false, 'media_buttons' => false, 'textarea_rows' => 8, 'wpautop' => false, 'tinymce' => array( 'theme_advanced_buttons1' => 'p, bold, italic, ul, |,link,unlink,code', 'theme_advanced_buttons2' => '', 'theme_advanced_buttons3' => '', 'theme_advanced_buttons4' => '', ),); public function __construct() { add_action('show_user_profile', array($this, 'initDescriptionWysywig')); add_action('edit_user_profile', array($this, 'initDescriptionWysywig'));} public function initDescriptionWysywig($options) { if ( ! class_exists('_WP_Editors' ) ) require_once( ABSPATH . WPINC . '/class-wp-editor.php' ); $options = _WP_Editors::parse_settings('description', $this->tinymceOptions); _WP_Editors::editor_settings('description', $options); wp_print_styles('editor-buttons');} }new CustomUserProfile();
