I have a very weird problem, my custom forms submition doesn't work unless devel module is active. any ideas how to solve this problem?

function forexCompare_form_submit($form,&$form_state){

$array = unserialize(variable_get('forexCompare_company1',""));

$array[] = t($_POST['forexCompare_company1']);
variable_set('forexCompare_company1',serialize($array));
//drupal_set_message(print_r($form_state)." k".$_POST['forexCompare_company1']);
}

function forexCompare_form($form,&$form_state){
return array(
            'forexCompare_company1' => array(
                '#type' => 'select',
                '#title' => 'Company #1',
                '#options' => getCompanies()
            ),
            'forexCompare_company2' => array(
                '#type' => 'select',
                '#title' => 'Company #2',
                '#options' => get_stored_comp()
            ),
            'submit' => array(
                '#type' => 'submit',
                '#value' => 'Save',
            ),
            '#submit' => array(
               'forexCompare_form_submit'
            )

);
}

i have notice that when i return the drupal_get_form() on the page callback , but when i pass it as variable in theme function doesnt work

function userOptions_theme(){
global $user;
$user_loaded = user_load($user->uid);
return array(
  'settings_user_transfer'=>array(
      'template' => 'setting',
      'variables' => array('money' => $user_loaded,'form' => drupal_get_form('userOptions_form'))
  )
);
}

    I don't have the answer to your question, but I want to mention that directly inserting $_POST values in your database doesn't seem like a good idea. Use $form_state['values'] when processing submitted values in a submit handler. – marcvangend May 20 '12 at 21:05
  • @marcvangend +1. Seems you're using some templates. Make sure you're not missing the from_id, form_token in template. – niksmac May 21 '12 at 5:38
  • actually i use drupal_render($form), do i still have to render these elements individually too. – Ramy Selim May 21 '12 at 9:13
  • i have a feeling that you cant pass form as a variable in template – Ramy Selim May 21 '12 at 9:29
  • @RamySelim normally you don't have to use drupal_render($form); you just return the output of drupal_get_form() in a menu callback. See form_example.module for an example. – marcvangend May 21 '12 at 11:39

There are a few things wrong with your approach, don't use $_POST, the values are there in &$form_state and you will break Drupal form handling using $_POST. If you have devel running use dpm() to explore that array.

In the theme function call drupal_get_form with the right name: forexCompare_form, i.e. drupal_get_form('forexCompare_form'). Or was the theme function just an example.

As marcvangend said, I dont have to use drupal_render() inside the template, and now i know why the forms was working when devel module is active, becuase it was building the theme register on every page request.

Thank you all for your help
