[helloise]

the line : echo $form['catcher_id'] gives me a dropdown list which was defined in a base class as:
'catcher_id' => new sfWidgetFormPropelChoice(array('model' => 'LpmCatcher', 'add_empty' => false)),

when i choose another item from the dropdown i want to do a few things but my code not working:
$selected_catcher = $form['catcher_id'];
foreach($selected_catcher as $val)
{
$catcher_name = $val->getName();
echo $catcher_name." ".$val->getId();

if ($catcher_name = "zed-catcher")
{
echo $form['service_code']->renderLabel();
echo $form['service_code']->renderError();
echo $form['service_code'];

}
}

helloise,

Please use [php] and [/php] BBCode Tags when posting code, of any size.

Also - Since you are using an outside class - or an API to extend functionality of that other software, what you have provided us won't help.

1. "not working" - what exactly isn't working, please be as descriptive as possible, tell us what is happening, and what is intended to happen

2. If this is an API to extend functionality of another software, you are best to post in the forums for that specific software, as you will find a harder time to find someone here who ahs used the same software.

3. If this is an outside class - and the class license allows it to be posted (VERY important) such as GPL, post the class that you are using, so we can see how it is intended to work.

Once you give us the additional information hopefully we can help.
