I'm a complete CakePHP and AJAX newbie. I'm trying to set up a pretty
simple ajax select element where my selecting an option in select A
will display relevant choices in a new select B. For whatever reason,
the code I've implemented is not working. My guess is that I'm missing
something vital in the ajax action, but I've tried everything I can
think of with no results.
Here is what I have:
******************************ajax action controller:
function users_from_company()
{
$this->layout = 'ajax';
$users = $this->User->findAll(array('company_id' =>
$this->data['company']));
$optionElements = array();
foreach ($users as $user)
{
$optionElements[$user['User']['id']] =
$user['User']['username'];
}
$this->set('optionElements', $optionElements);
}
******************************view:
<p>
Company:
<?php
$companyselect = array();
foreach ($companies as $company)
{
$companyselect[$company['Company']['id']] =
$company['Company']['company_name'];
}
echo $html->selectTag('Video/company_id', $companyselect, null,
array('id' => 'company'));
?>
</p>
<p>
<div id="usersFromCompany"></div>
</p>
<?php
echo $ajax->observeField('company', array('frequency'=>1,
'url'=>'/videos/users_from_company/', 'update'=>'usersFromCompany',
'with'=>'company'));
?>
************************************ajax output view:
<?php $html->selectTag('Video/user_id', $optionElements); ?>
