Webform ID not shown in debug output?

Question

I created a new module to extend the webform module for custom submission hooks:

function mywebform_extra_form_alter(&$form, &$form_state, $form_id) {
    if ($form_id == 'webform_client_form_213') {
        $first = array_shift($form['#submit']);
        array_unshift($form['#submit'], $first, 'mywebform_extra_submit_213');
    }
}

I have the webform module installed and I created a webform that has a node id of 213.

When I try to output the $form_id variable, the value shown is nothing indicative of a webform and instead showing "search_form_block" as the form ID?

what is the error here? I pulled it straight from this example.

1. Install the Devel module.

2. Use the dpm() function, it will print out $form_id for all forms on any page you visit.

   function mywebform_extra_form_alter(&$form, &$form_state, $form_id) {
     dpm($form_id);
   }
