Autocomplete, clearing form values and Drupal form fields
Some browsers like to be helpful and help by remembering certain form fields. I was having a problem with Firefox auto-populating my some of my form fields (specifically field type 'password' and 'password_confirm') in a custom module I wrote.
After some consternation, I referred to our cardboard cutout Han Solo, who helped me to remember a bit more about form options and field auto-completion.
To fix this problem just add an #attribute of 'autocomplete' => 'off', e.g.
<?php
/**
* Implementation of hook_form()
*/
function mymodule_form() {
$form['old_password'] = array(
'#title' => t('Old Password'),
'#type' => 'textfield',
'#attributes' => array('autocomplete' =>'off'),
'#required' => TRUE,
);
$form['new_password'] = array(
'#type' => 'password_confirm',
'#attributes' => array('autocomplete' =>'off'),
'#required' => TRUE,
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Submit'),
);
$form['clear'] = array(
'#type' => 'button',
'#value' => t('Clear'),
'#attributes' => array('onclick' => 'this.form.reset(); return false;'),
);
return $form;
}The example above also includes a nifty way to clear out form fields via javascript in the $form['clear'] element.

I love talking to Han. We need to get a picture of him up on the website soon.

Thx for sharing this script. I have used some of this in my first drupal module, used for theming the user registration page.
Really like your code for clearing a drupal form. This seems to work well apart from clearing the username and email address fields.
Not sure if this is related but I can;t seem to get the autocomplete part to (not) work. Not sure but I guess this is controlled through the use of sessions and the browser. Also when I looked at drupal's fapi I could see no documentation for this although it did mention about autocomplete_path. Is this the same?

This is sample code that would go in a module. Here is a tutorial for creating modules in Drupal 6: http://drupal.org/node/206753
