requestAction() public ¶

requestAction( mixed $url , array $extra = array() )

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

mixed $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.
