Disabling Generate automatic URL alias checkbox on node edit/add by default

Thu, 03/03/2016

Disabling Generate automatic URL alias is not possible with configuration, this needs to be done with code.

In hook_form_alter we call

/**
* Implements hook_form_alter().
*/
function myModule_form_alter(&$form, &$form_state, $form_id) {
  // disable auto generating of URLs with pathauto
  if ($form['#entity_type'] == "node"){
    $form['#after_build'][] = 'myModule_after_build';
  }

and then we create that after build myModule_after_build

/**
 * Custom after build function
 */
function myModule_after_build($form, &$form_state) {
 // Unchecks Generate automatic URL alias 
 $form['path']['pathauto']['#checked'] = FALSE;
 return $form;
}
