requestActionsource public

requestAction( string|array $url , array $extra array() )

Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.

Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()

Passing POST and GET data

POST and GET data can be simulated in requestAction. Use $extra['url'] for GET data. The $extra['data'] parameter allows POST data simulation.

Parameters

string|array $url

String or array-based URL. Unlike other URL arrays in CakePHP, this URL will not automatically handle passed and named arguments in the $url parameter.

array $extra optional array()

if array includes the key "return" it sets the AutoRender to true. Can also be used to submit GET/POST data, and named/passed arguments.

Returns

mixed
Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.

toStringsource public

toString( )
