I am trying to add a custom validation function to an existing form. I am using hook_form_FORM_ID_alter() to edit the form. I am then adding a new function to the #validation array. When I use dpm() and print out $form['#validation'] I can see that my function is there. However the validation step is not running. If I dpm() in the validation function it is not hit.

/**
 *  Implements hook_form_FORM_ID_alter().
 */
function mymodule_form_mycustomdorm_form_alter(&$form, &$form_state, $form_id) {
    $form['#validate'][] = 'mymodule_test';
    dpm($form['#validate']);       
}

function mymodule_test($form, &$form_state) {
  dpm($form_state);
}
  • Have you cleared the caches since adding the hook function? – Clive Jan 20 '15 at 16:49
  • @Clive first thing I do when something is not working. No joy. – Bobby Jan 20 '15 at 16:54

    @DEVARAJJOHNSON Please don't edit questions to modify people's code - it makes it impossible to answer the question. Thanks – Clive Jan 20 '15 at 17:49
  • Are you sure that "mycustomdorm_form" is right? Is it your FORM_ID? – arrubiu Jan 20 '15 at 18:24

Hi Bobby you can use custom validate submit handler to deal with this

$form['submit']['#validate'][] = 'custom_validate_function'

all you have to use is #validate in submit handler.

use the same callback function as above with replacing the callback name
