  • The hook that i have will apply to all forms at the moment. I just want it to apply to on particular page. ie., page-node-172 (i get this from fireBug) – fitnessCraze Sep 3 '14 at 15:41

The $form array contains a #node key which has the nid attribute. Use that to filter like so:

if($form['#node']->nid == 1072) { ... }

However, since you ask for page-node-1072 it sounds like you want to put something in that particular page template, in which case you should use a process or preprocess function to add or alter variables for the template.

If you only want to alter the form on a single page @betherwisser 's answer is the right one. If you want to alter all pages of type webform_client_form, then leave out:

if (strpos($form_id, 'webform_client_form') !== FALSE) {}

and relpace it with the function hook_form_FORM_ID_alter. In your case:

jhumobileform_form_webform_client_form_alter(&$form, &$form_state, $form_id)

to find out the actual form_id (not sure whether 'webform_client_form' is the right one) install the devel module and activate it, then put dpm($form) in your function:

 function jhumobileform_form_alter(&$form, &$form_state, $form_id) { dpm ($form); //or directly dpm($form_id); } 

Then, navigate to the site of the form as admin. Within the $form array you can also find the #node key.

  • new idea. what if its using a specific theme? is there a way? – fitnessCraze Sep 10 '14 at 3:15
