|
|
*
|
|
* In your view: $this->Flash->render('somekey');
|
|
* Will default to flash if no param is passed
|
|
*
|
|
* You can pass additional information into the flash message generation. This allows you
|
|
* to consolidate all the parameters for a given type of flash message into the view.
|
|
*
|
|
* ```
|
|
* echo $this->Flash->render('flash', array('params' => array('name' => $user['User']['name'])));
|
|
* ```
|
|
*
|
|
* This would pass the current user's name into the flash message, so you could create personalized
|
|
* messages without the controller needing access to that data.
|
|
*
|
|
* Lastly you can choose the element that is used for rendering the flash message. Using
|
|
* custom elements allows you to fully customize how flash messages are generated.
|
|
*
|
|
* ```
|
|
* echo $this->Flash->render('flash', array('element' => 'my_custom_element'));
|
|
* ```
|
|
*
|
|
* If you want to use an element from a plugin for rendering your flash message
|
|
* you can use the dot notation for the plugin's element name:
|
|
*
|
|
* ```
|
|
* echo $this->Flash->render('flash', array(
|
|
* 'element' => 'MyPlugin.my_custom_element',
|
|
* ));
|
|
* ```
|
|
*
|
|
* @param string $key The [Message.]key you are rendering in the view.
|
|
* @param array $options Additional options to use for the creation of this flash message.
|
|
* Supports the 'params', and 'element' keys that are used in the helper.
|
|
* @return string|null Rendered flash message or null if flash key does not exist
|
|
* in session.
|
|
* @throws UnexpectedValueException If value for flash settings key is not an array.
