Documentation on using Horde_Controller
++ General Info
++ Horde_Controllers in Horde Core Apps
Horde Controllers are independent from the Horde Ajax Framework.
Controllers need Horde_Routes and need rewrite rules.
Ajax application controllers do not live in lib but in
$app/app/controllers/
Example:
class Nag_CompleteTask_Controller in nag/app/controllers/CompleteTask.php
<code>
<?php
class Nag_CompleteTask_Controller extends Horde_Controller_Base
{
public function processRequest(Horde_Controller_Request $request,
Horde_Controller_Response $response)
{
/* Toggle the task's completion status if we're provided with a
* valid task ID. */
$requestVars = $request->getRequestVars();
if (isset($requestVars['task']) && isset($requestVars['tasklist'])) {
$nag_task = new Nag_CompleteTask();
$result = $nag_task->result($requestVars['task'],
$requestVars['tasklist']);
} else {
$result = array('error' => 'missing parameters');
}
$requestVars = $request->getGetVars();
if (!empty($requestVars['format']) &&
$requestVars['format'] == 'json') {
$response->setContentType('application/json');
$response->setBody(json_encode($result));
} elseif ($requestVars['url']) {
$response->setRedirectUrl($requestVars['url']);
}
}
}
?>
</code>
A Horde Controller based app needs a config/routes.php file.
For example
<code>
<?php
/**
* Setup default routes
*/
$mapper->connect('/t/complete',
array(
'controller' => 'CompleteTask',
));
?>
</code>
defines a route for a call like www.myhorde.de/nag/t/complete to be
handled by the CompleteTask controller seen above.
The endpoint script is horde/rampage.php - rampage.php currently
seems to handle only authenticated calls.
The controller is passed the request (in this case, a json request)
and handles it (with a json answer in this case)
