Consider I have 3 content type. The problem is that if I use form alter in a module , when I use:

drupal_set_message(t($form_id), 'status', FALSE);

in the mentioned hook, it shows me different set of form-IDs as message on showing each node add/edit form.

For example if I go to node type A add/edit form, drupal_set_message shows:


if I go to node type B add/edit form, drupal_set_message shows:


if I go to node type C add/edit form, drupal_set_message shows:


Showing them means that I can not really make an specific effect for each content type add/edit form by form_alter.

Note: I use OG module and B and C are the content types and A is the group type.

How should I solve it?


In the case you need, so you can easily use control flow in your hook_form_alter

You know that the hook runs everytime a form is willing to be rendered, so you can easily do something like

hook_form_alter(&$form, &$form_state, $form_id){

if($form_id == 'A_node_form'){...}//alter form A

if($form_id == 'B_node_form'){...}//alter form B

if($form_id == 'C_node_form'){...}//alter form C

  • I edited the title of my question. As I told previously, my system checks almost all forms in each node add/edit form. and I really do not know where is causing this problem! – Ehsan Nov 17 '14 at 15:05
  • Your answer works for normal situations where system only checks a form related to the shown form. – Ehsan Nov 17 '14 at 15:06
  • Ok I understand check the answer again – svelandiag Nov 17 '14 at 15:16
  • Actually, it's a bug belonging to Pages and Panels, whenever I customize the node edit form it happens! – Ehsan Nov 17 '14 at 15:53
  • So in your code, whole conditions will be true for almost all forms, that's my problem! – Ehsan Nov 17 '14 at 15:53
