This provides some of the DRY magic CakePHP provides. If you want to shut it off, redefine this method as an empty function.

Parameters

array $properties: The name of the properties to merge.
string $class: The class to merge the property with.
boolean $normalize optional true: Set to true to run the properties through Set::normalize() before merging.

_set() protected ¶

_set( array $properties = array() )

Allows setting of multiple properties of the object in a single line of code. Will only set properties that are part of a class declaration.

Parameters

array $properties optional array(): An associative array containing properties and corresponding values.

_stop() protected ¶

_stop( integer|string $status = 0 )

Stop execution of the current script. Wraps exit() making testing easier.

Parameters

integer|string $status optional 0: see http://php.net/exit for values

string $method: Name of the method to call
array $params optional array(): Parameter list to use when calling $method

Returns

mixed
Returns the result of the method call

log() public ¶

log( string $msg , integer $type = LOG_ERROR )

Convenience method to write a message to CakeLog. See CakeLog::write() for more information on writing to logs.

Parameters

string $msg: Log message
integer $type optional LOG_ERROR: Error type constant. Defined in app/Config/core.php.

Returns

boolean
Success of log write

requestAction() public ¶

requestAction( mixed $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

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.

toString() public ¶

toString( )

Object-to-string conversion. Each class can override this method as necessary.

Returns

string
The name of this class
