Getting and Setting Application Properties

Problem

I need to retrieve or set some of the properties about my application.

Solution

Use the Admin.getAppProperties() method to retrieve properties:

$targetProps = array('application_name','description');

$properties = $facebook->api_client->admin_getAppProperties($targetProps);

Use the Admin.setAppProperties() method to set properties:

$setProps = array('description' => 'My new description!');

$return = $facebook->api_client->admin_setAppProperties($setProps);

Discussion

Admin.getAppProperties() returns an array, with each named element being one of the properties you requested. In addition to whatever you ask for, Facebook will always return your app’s canvasname, icon_url, and logo_url appended to the end of the returned array.

Admin.setAppPropoerties() will return a code indicating whether it worked. Confusingly, it returns true as the value 1 if it works, which coincides with error code 1, which signifies an unknown error (see Batching Calls). If you’re concerned it’s not working, you can do a check using Admin.getAppPropoerties():

$setProps = array('description' => 'This was set using the new

Admin.setAppProperties() method!');

$return = $facebook->api_client->admin_setAppProperties($setProps);

$getProps = array('description');

$newDesc = $facebook->api_client->admin_getAppProperties($getProps);

if($newDesc['description'] == $setProps['description']){

echo 'Success!';

}

NOTE

These methods are currently marked as beta in the Developers Wiki, so treat them with a little caution and make sure to report any bugs you might find to the Facebook Bug Tracker, at http://bugs.developers.facebook.com.

The list of properties you can specify in either method is pretty extensive and covers basically anything that you set in the Developer app (see Table 9-5, but for the most up-to-date list, refer to http://wiki.developers.facebook.com/index.php/ApplicationProperties).
