How to set a POST data in value in FAPI

Question

I'm trying to port a working FAPI module from D6 to D7. I'm passing a POST value to the form and then assigning using :

 $link = check_url(substr($_POST['file_link'], 0, 300));
     $form['anu_download_file_link'] = array(
        '#type' => 'value',
        '#value' => $link,
      );

But when form is submitted the form is built again but this POST data file_link is missing in the submit handler.

In D6 $form['#cache']=true was working fine which avoided recreating of the form but now in D7 it does not seem to work.

How can pass POST values to the submit handler?

Answer 1

We need to use in D7 :

$form_state['cache'] = TRUE;
$form_state['no_cache'] = FALSE;

instead of

$form['$cache']=TRUE in D6
