How to get values from $form_state with webform

Question

I'm using webform for submission and trying to simulate GET parameters (though by default it uses POST).

Here's my code implementing hook_form_alter():

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  $nid = 2;
  if ($form_id == 'webform_client_form_' . $nid) {
    $option['query'] = array(
        'name' => $form_state['values']['name'], 
        'email' => $form_state['values']['email'], 
        'gender' => $form_state['values']['gender'], 
        'birthday' => $form_state['values']['birthday'], 
        );
    $form['#action'] = url('path/to/myViewsPage', $option);
  }

Above code should take me to

'path/to/myViewsPage?name=tom&email=tom@gmail.com&gender=male&birthday=12/21/2013'

But I got following error:

Undefined index: values in mymodule_form_alter()

Could someone tell me where to define the $form_state['values']? Isn't it predefined by Webform?

Answer 1

In your form_alter() you should ADD a new submission handler.

function mymodule_form_alter($form, &$form_state, $form_id) {
 $nid = 2;
  if ($form_id == 'webform_client_form_' . $nid) {
    $form['#submit'][] = 'your_submit_handler';
  }
 }

In your_submit_handler() these values will be available

function your_submit_handler(&$form, &$form_state) {
   $option['query'] = array(
    'name' => $form_state['values']['name'], 
    'email' => $form_state['values']['email'], 
    'gender' => $form_state['values']['gender'], 
    'birthday' => $form_state['values']['birthday'], 
   );
   $url = url('path/to/myViewsPage', $option);// (valid path or whatever)
   $form_state['redirect'] = $url;
}

You dont care about the webform node being saved you only need to redirect, right? This will run alongside with yout default webform submit handler.

Answer 2

It's a bit hackish, but I think it would it be better if you set the path to your View in $form['#action'] and post the form directly to your View. Then on your Views page you grab the posted values from the form, in a contextual filter if you need that. In that way you also completely bypass the submission handling and nothing is saved.

Answer 3

//  echo"<pre>"; print_r($form_state); die;
/*** here you check all values of webform which is submitted ***/

$fname = $form_state['input']['submitted']['Your_field_ID'];

Answer 4

Webform has its own hook to access the submit and all. You could use hook_webform_submission_presave().

Modify a Webform submission, prior to saving it in the database.

Parameters

$node: The Webform node on which this submission was made.

$submission: The Webform submission that is about to be saved to the database.

See All Webform Module Hooks.

Try this:

 $form_state = form_state_defaults();
 $form_build_id = $_POST['form_build_id'];
 // Get the form from the cache.
 $form = form_get_cache($form_build_id, $form_state);

or by providing the form id:

// Get the form.
$form = drupal_get_form('my_form_id');
// Get the default form state.
$form_state = form_state_defaults();
// Get the form and form state from the cache for the form you just got.
form_get_cache($form['#build_id'], $form_state);
