How to pass different parameters to the same form function based on different urls

Question

I have a custom model containing two paths. Each path goes to the same function. I wanna to send to each page arguments specific parameter and reception on the function then pass the hidden value to submit function.

  $items['parkingcalculator_normal'] = array(
    'title' => t('Parking calculator'),
    'description' => 'Parking Calculator Page',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('parkingcalulator_form',0),
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );
  $items['parkingcalculator_valet'] = array(
    'title' => t('Parking calculator'),
    'description' => 'Parking Calculator Page',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('parkingcalulator_form',0 ),
    'access callback' => TRUE,
  );
function parkingcalulator_form($form, &$form_state , $type){...}

but the function does not take the parameter and does not pass the value in the hidden form type to

function parkingcalulator_form_submit($form, &$form_state ,$type)

Answer 1

Remove $form from the submit function and just keep the $form_state.

The function would look like

function parkingcalulator_form_submit(&$form_state ,$type)

Answer 2

In parkingcalulator_form($form, &$form_state, $type), create a hidden form element to store the data you need for your submit function:

$form['type'] = array('#type' => 'hidden', '#value' => $type);

Then in your submit function parkingcalulator_form_submit($form, &$form_state) you can access that value:

$type = $form_state['values']['type'];
