Question

Hi Stackoverflow community,

I am creating a voting system with many categories using the FormAPI.

I built the form with drupal_get_form() and stored the html markup into a textarea in a CCK field. I also built the submit function which deals with the database.

However, when I display the node, the form can be construct however, the submission function is not called. I can’t figure out the source of the problem. Any advice is appreciated, thanks!

*EDIT:

Defines the form:

function judges_nodeapi(&$node, $op, $teaser, $page) { 
switch ($op) {
    case 'view':

        ...

        $node->field_judging_form[0]['value']=drupal_get_form('judges_entry',($node));

        node_save($node);
}
}



  function judges_entry($form_state, $node){
    ...
    return $form;
}

Then I’m simply using CCK to display the form as plain text.

Each time you call drupal_get_form() a new token is generated (for security reasons), so you can’t render a form statically into a field and expect it to ever work.

What you need to do is get a fresh version of the form every time you display it by implementing hook_preprocess_node and then outputting the form in your template file. Something like this in your module file:

function MYMODULE_preprocess_node(&$vars) {
  $vars['my_form'] = drupal_get_form('judges_entry',($vars['node']));
}

Then in your template file (node.tpl.php):

echo $my_form;

Hope that helps
