requestAction() 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
Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.
toString() public ¶
toString( )
Object-to-string conversion. Each class can override this method as necessary.
Returns
The name of this class
