Hi all,

I will appreciate an help with the following.
I am building a form with a submit form handler.

The form is working well (it give me back the text string i submit)
The problem is that I get the result in a blank page without the theme,
I attach below the code of my submit function.

I do not understand what is wrong.

Thanks

function myform_nameform_submit($form, &$form_state) {
  $ricerca = array (
  'text' => $form_state['values']['text'],
  );
  $output = print $ricerca['text'];
   return $output ;
 }

A few things:

Concerning $output = print $ricerca['text'];

You can drop the word print here as that is printing straight out to the screen instead of stroring the value in $output. The print function always returns 1 so $output would become 1 (see http://php.net/manual/en/function.print.php)

The fact that you are printing directly to the screen is most likely the reason you have lost the rest of your theme, as drupal builds up a themed page of output for each request but I think you are interupting that process here.

Also I dont think it is meaningful to return a value from a form submit function, generally speaking you would do some data storage / processing here and then redirect somewhere else by storing a path in $form_state['redirect'].

If you want to see your value displayed on the redirected page you can drupal_set_message($form_state['values']['text']);
