I'm trying to wrap my head around the process of creating a form and handling the submitted data using x_submit().

I start by having a form callback:

function world_form(&$form_state) {

  // if ($form_state['post']) { drupal_set_message("Solved!"); }

  $forms['fieldset_options'] =
    array('#type' => 'fieldset',
          '#title' => t('Options'),
          '#collapsible' => FALSE,
          '#collapsed' => FALSE);

  $forms['fieldset_options']['tags'] =
    array('#type' => 'item', '#title' => 'Simple stuff');

  $forms['fieldset_options']['checkbox1'] =
    array('#type' => 'checkbox', '#title' => t('Solve world problems'));

  $forms['fieldset_options']['submit'] =
    array('#type' => 'button', '#button_type' => 'submit', '#value' => 'Go!');

  // $forms['submit'] = array('#type' => 'submit', '#value' => 'Go!');

  return $forms;

So I specify a theme callback, which takes me to a file world.tpl.php in which I do:

print drupal_get_form('world_form');

which invokes my form callback. So far so good. Now the problem I have is that I want to handle when this form is submitted (more specifically, I want the value of the checkbox when it is checked). I read a lot of documentation and most mention the world_form_submit function. So I create one like this:

function world_form_submit($form, &$form_state) {

But after I've done that the function isn't called. However if I instead use the line which is commented out in my form function and comment out the '#type' => 'button' field it DOES get called and I can now access the checkbox state, however the problem I have now is that the form is not updated with the state of the checkbox (I.e. if I check the box and submit I get to the same page but the box is no longer checked).

So my questions are:

  1. Why isn't the _submit callback called when I use a "regular" submit button? Do I have to use the $forms['submit'] way?
  2. If I do get the _submit callback called, can I still update my form to reflect what it was before I submitted, and
  3. How can I get the checkbox state in my world.tpl.php file? Say I want to print something if it is checked.

Thank you for your time.

Many questions here:

  • Your form function function should return the form array and doesn't need an argument unless you need it for something specific.
  • You should at least have an element of type 'submit' (not button) in your form.
  • Chances are good your submit function will get called if you implement it this way.
  • If the form fails validation, FAPI will restore it to the values submitted, keeping what was typed by the user.
  • You shoudn't try to embed business logic in your template, but rather in your module and/or a preprocess function.

  • Sorry I forgot to add the return statement in the example. I added it now. It is there. But the problem for me now is still that I want to do something with my checkbox values... assuming I do something in my _submit function, how would I return the result to the template file? E.g. I fetch data from a db in the _submit function, where do I store that data to have it printed out in the template?

  • Ideally, with a theme function. This document may be of help.
