Drupal - How can I remove preview button from contact form?
A custom module can utilize hook_form_alter()
to strip out the preview button form element in any form:
/**
* Implements hook_form_alter().
*/
function MYMODULE_form_alter(&$form, $form_state, $form_id) {
// Look for any form provided by the contact module.
// If you want to target a specific form you'll use the whole form ID
// (e.g. Website feedback = 'contact_message_feedback_form').
if (strpos($form_id, 'contact_message_') !== FALSE) {
$form['actions']['preview']['#access'] = FALSE;
}
}
