Method Detail
addFormat() public ¶
addFormat( string $formatName , array $options )
Add a currency format to the Number helper. Makes reusing currency formats easier.
{{{ $number->addFormat('NOK', array('before' => 'Kr. ')); }}}
You can now use NOK as a shortform when formatting currency amounts.
{{{ $number->currency($value, 'NOK'); }}}
Added formats are merged with the following defaults.
{{{ array( 'before' => '$', 'after' => 'c', 'zero' => 0, 'places' => 2, 'thousands' => ',', 'decimals' => '.', 'negative' => '()', 'escape' => true ) }}}
Parameters
- string $formatName
- The format name to be used in the future.

- The class to merge the property with.
- boolean $normalize optional true
- Set to true to run the properties through Set::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

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
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
