_mergeVars() protected ¶

_mergeVars( array $properties , string $class , boolean $normalize = true )

Merges this objects $property with the property in $class' definition. This classes value for the property will be merged on top of $class'

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

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

dispatchMethod() public ¶

dispatchMethod( string $method , array $params = array() )

Calls a method on this object with the given parameters. Provides an OO wrapper for call_user_func_array

array $params optional array()
Parameter list to use when calling $method
Returns
mixed
Returns the result of the method call

Parameters
string $msg
Log message
integer $type optional LOG_ERR
Error type constant. Defined in app/Config/core.php.
null|string|array $scope optional null

The scope(s) a log message is being created in. See CakeLog::config() for more information on logging scopes.

Returns
boolean
Success of log write

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
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
