I am trying to remove two select list items from a form using this code:

function module_r_form_alter(&$form, &$form_state, $form_id)
    if ($form_id == 'forum-node-form') {

The above code is not working. I would greatly appreciate any help you can give me in working this problem.


If the name of your field is edit-taxonomy-forums-und your code should be:


Maybe you don't have the correct name of the field. Go to the Manage fields page of your content type (YOUR_SITE/admin/structure/types/manage/YOUR_CONTENT_TYPE/fields) and check the name of the field.

If you read the comments in the answer you will see that the problem was the change of forum_node_form by forum-node-form.

  • Thank you for your prompt reply. It still does not work. What I am trying to alter is select list from taxonomy_forums. .

    Hi @Dominick i think you have to recheck your $form_id. This should be 'forum_node_form' instead of "'forum-node-form'. Jan 30 '16 at 8:49

    Sorry to question your answer, but I would integrate the last 2 comments as a "2nd possibility" (or something like that) ... Because that seems to be the real answer to this question ... no? Aug 21 '16 at 7:09
