I am trying to use the drupal_get_form funtion outside of a menu and am not having any luck finding examples of how this is done.

An overview of what I am trying to achieve is: 1) Pass control from a script using an href html tag passing to another script that will then read what has been passed to the new script and build a form based on the action that has been passed in. I am using the drupal_get_form function just as you would any php function. 2) I am also getting a message that says drupal_get_form is an unknown function.

This script is the initial calling script that contains an html href link to the called processing script.

function view_payment_methods() {   try {$result = db_select('tls_connect_cashier_payment_methods', 'q')     ->fields('q', array('id', 'payment_method', 'payment_desc', 'logically_deleted', 'system_or_user'))     ->orderBy('payment_desc')     ->execute();   } catch(Exception $e) {     watchdog_exception(       'view_payment_methods',       $e,       'Select from tls_connect_cashier_payment_methods has failed.',       null,       'Alert'     );      return false;   }   $payment_methods = $result->fetchAll(PDO::FETCH_ASSOC);    $col1_label           = t('Payment Method');   $col2_label           = t('Payment Description');   $col3_label           = t('Disabled');   $col4_label           = t('Created By');   $col5_label           = t('Action');   $edit_label           = '(' . t('Edit') . ')';   $delete_label         = '(' . t('Delete') . ')';    $markup  = "<h1>" . t('Payment Methods') . "</h1>";   $markup .= "<table>";   $line    = "<tr>";   $line   .= "<td>" . $col1_label . "</td>";   $line   .= "<td>" . $col2_label . "</td>";   $line   .= "<td>" . $col3_label . "</td>";   $line   .= "<td>" . $col4_label . "</td>";   $line   .= "<td>" . $col5_label . "</td>";   $line   .= "</tr>";   $markup .= $line;   if (isset($payment_methods[0])) {     foreach ($payment_methods as $entry) {       $disabled          = '';       $created_by        = '';       $id                = $entry['id'];       $payment_method    = $entry['payment_method'];       $payment_desc      = $entry['payment_desc'];       $logically_deleted = $entry['logically_deleted'];       $system_or_user    = $entry['system_or_user'];       $line              = "<tr>";       $line             .= "<td>" . t($payment_method) . "</td>";       $line             .= "<td>" . t($payment_desc) . "</td>";       if ($disabled == 0) {         $disabled      = 'No';       } else {         $disabled      = 'Yes';       }       $line             .= "<td>" . t($disabled) . "</td>";       if ($system_or_user == 'S') {         $created_by    = 'System';       } else {         $created_by    = 'User';       }       $line             .= "<td>" . t($created_by) . "</td>";       $line             .= "<td><a href = '/TLSConnect3App/sites/all/modules/custom/TLSConnectPackage/cashier/PaymentMethodEditDelete.php?action=edit&id=" . $id . "'>" . $edit_label . "</a>                         <a href = '/TLSConnect3App/sites/all/modules/custom/TLSConnectPackage/cashier/PaymentMethodEditDelete.php?action=delete&id=" . $id . "'>" . $delete_label . "</a></td>";       $markup           .= $line;     }   }   $markup .= "</table>";    return $markup; } 

This script is the called script accessed by way of the html href link for the edit link.

if (isset($_GET['action'])) {   $id = $_GET['id'];   switch ($_GET['action']) {     case 'edit':       $form_id = 'edit_form';       return drupal_get_form($form_id);       break;     case 'delete':       break;   } }  function edit_form($form, &$form_state) {     global $id;     die('chuck');     $form = array(); }
