Often the quickest way to work thing out is to look at how other modules do things.

ok there is two different things here.

mod_form.php is linked to mod_edit.php.
So you have very few control on this form.
The only control i get, is to add control with exact name as database field name in the table : PREFIX_MODULE_NAME.

Then i guess what you want to do is to make your own form that will react to your own script

I was in the same case as you few weeks before, don't worry there is a solution.

This is how i proceed :

1) i create two files :
- my_page.php
- my_page_form.php

2) In 'my_page_form.php' i define my form as explain in formslib doc :
[code]
require_once ($CFG->dirroot.'/course/moodleform_mod.php');

class mod_MODULE_NAME_MY_PAGE_form extends moodleform {
// form definition
function definition() {

global $COURSE;
$mform =& $this->_form;

//-------------------------------------------------------------------------------
$mform->addElement('header', 'header1', get_string('header1', 'MODULE_NAME'));
/* a text field */
$mform->addElement('text', 'textfield1', get_string('textfield1', 'MODULE_NAME'), array('size'=>'64'));
$mform->addRule('textfield1', get_string('required'), 'required', null, 'client');
//-------------------------------------------------------------------------------
// add standard buttons, common to all modules
$this->add_action_buttons();
}

// form validation
function validation($data) {
$errors= array();

return $errors;
}
}
[/code]

3) In 'my_page.php', define how the form must react with the database

[code]
require_once('./my_page_form.php');

//you'll process some page parameters at the top here and get the info about
//what instance of your module and what course you're in etc. Make sure you
//include hidden variable in your forms which have their defaults set in set_data
//which pass these variables from page to page

$mform = new mod_MODULE_NAME_MY_PAGE_form('./my_page.php', null, 'post');

if ($mform->is_cancelled())
{
//you need this section if you have a cancel button on your form
//here you tell php what to do if your user presses cancel
//probably a redirect is called for!

redirect('./view.php?id='.$cm->id, '',0);
}
else if ($fromform=$mform->get_data())
{
//this branch is where you process validated data.

/* Prepare dataobject to submit to the database */
$data_object->my_text = $fromform->textfield1;
/* Submit object to the database */
update_record(TABLE_NAME, $data_object);
/* Redirection */
redirect('LINK_TO_THE_PAGE_IT_SHOULD_GO, '',0);
}
else
{
// this branch is executed if the form is submitted but the data doesn't validate and the form should be redisplayed
// or on the first display of the form.
//put data you want to fill out in the form into array $toform here then :

if(isset($toform))
{
$mform->set_data($toform);
}
// give focus to the first form element
$mform->focus();

// display form
$mform->display();

}
[/code]
4) Adapt this method to your needs
