You'll have to extend/decorate LeftAndMain
with your own extension and the action you want to call. Here's an example:
<?php
class MyExtension extends LeftAndMainExtension
{
private static $allowed_actions = array(
'doAction'
);
public function doAction($data, $form){
$className = $this->owner->stat('tree_class');
$SQL_id = Convert::raw2sql($data['ID']);
$record = DataObject::get_by_id($className, $SQL_id);
if(!$record || !$record->ID){
throw new SS_HTTPResponse_Exception(
"Bad record ID #" . (int)$data['ID'], 404);
}
// at this point you have a $record,
// which is your page you can work with!
// this generates a message that will show up in the CMS
$this->owner->response->addHeader(
'X-Status',
rawurlencode('Success message!')
);
return $this->owner->getResponseNegotiator()
->respond($this->owner->request);
}
}
Once you have written an extension like this, you'll have to apply it to LeftAndMain
by adding the following to your mysite/_config/config.yml
:
LeftAndMain:
extensions:
- MyExtension
That's it. Your doAction
button should now actually do something!
