How to disable TinyMCE per fields in Drupal

There is a theme() function in the Drupal tinymce module that lets you (the admin/webmaster) turn off the rich text editor on a field by field basis.

Basic steps to disable TinyMCE in a specific Drupal form field:

  1. Look in your modules/tinymce/tinymce.module file.
  2. Search for « theme_tinymce_theme ».
  3. Copy the entire function to your theme’s template.php file.
  4. Rename the function from theme_tinymce_theme() to yourthemename_tinymce_theme(). (Substitute « yourthemename » for your theme’s name.)
  5. Add a line to the switch($textarea_name){} block that specifies the name of the textarea you would like to exclude. Use the existing examples as a guide.

I wanted to disable the RTE for a custom plain text field in the node edit form. The field’s name is « field-teaser-0-value ». This is the line I added (marked with « KA ») with some surrounding logic: (The fully modified theme that I put into my template.php is at the end of the post.)


function theme_tinymce_theme($init, $textarea_name, $theme_name, $is_running) {
  switch ($textarea_name) {
    case 'field-teaser-0-value': // KA: blog teaser (we want plain text only)


To find the name of the field in question, load the form in your browser. Check the source code. Look for the name= » » attribute for your field. That’s the string you insert into the theme function.

Tip! For CCK (content) fields where the name is something like « field_teaser[0][value] », you need to replace the non-alphanumeric characters with a dash. So the $textarea_name variable for this field is actually written as « field-teaser-0-value ».

Here’s the final customized theme function I placed in my theme’s template.php file. My theme is called « avocadoshake » and my comments are marked with a « KA ».

 * Customize a TinyMCE theme.
 * @param init
 *   An array of settings TinyMCE should invoke a theme. You may override any
 *   of the TinyMCE settings. Details here:
 * @param textarea_name
 *   The name of the textarea TinyMCE wants to enable.
 * @param theme_name
 *   The default tinymce theme name to be enabled for this textarea. The
 *   sitewide default is 'simple', but the user may also override this.
 * @param is_running
 *   A boolean flag that identifies id TinyMCE is currently running for this
 *   request life cycle. It can be ignored.
function avocadoshake_tinymce_theme($init, $textarea_name, $theme_name, $is_running) {
  // KA: uncomment this print line (on a dev site!) to print out all the textarea names on a form
  // print "textarea_name = $textarea_name <br />";
  switch ($textarea_name) {
    // Disable tinymce for these textareas
    case 'log': // book and page log
    case 'img_assist_pages':
    case 'caption': // signature
    case 'pages':
    case 'access_pages': //TinyMCE profile settings.
    case 'user_mail_welcome_body': // user config settings
    case 'user_mail_approval_body': // user config settings
    case 'user_mail_pass_body': // user config settings
    case 'synonyms': // taxonomy terms
    case 'description': // taxonomy terms
    case 'workflow_comment': // workflow state comment
    case 'field-teaser-0-value': // KA: blog teaser (plain text only)

    // Force the 'simple' theme for some of the smaller textareas.
    case 'signature':
    case 'site_mission':
    case 'site_footer':
    case 'site_offline_message':
    case 'page_help':
    case 'user_registration_help':
    case 'user_picture_guidelines':
      $init['theme'] = 'simple';
      foreach ($init as $k => $v) {
        if (strstr($k, 'theme_advanced_')) unset($init[$k]);
