|
87 |
* Will default to flash if no param is passed
|
88 |
*
|
89 |
* You can pass additional information into the flash message generation. This allows you
|
90 |
* to consolidate all the parameters for a given type of flash message into the view.
|
91 |
*
|
92 |
* ```
|
93 |
* echo $this->Session->flash('flash', array('params' => array('class' => 'new-flash')));
|
94 |
* ```
|
95 |
*
|
96 |
* The above would generate a flash message with a custom class name. Using $attrs['params'] you
|
97 |
* can pass additional data into the element rendering that will be made available as local variables
|
98 |
* when the element is rendered:
|
99 |
*
|
100 |
* ```
|
101 |
* echo $this->Session->flash('flash', array('params' => array('name' => $user['User']['name'])));
|
102 |
* ```
|
103 |
*
|
104 |
* This would pass the current user's name into the flash message, so you could create personalized
|
105 |
* messages without the controller needing access to that data.
|
106 |
*
|
107 |
* Lastly you can choose the element that is rendered when creating the flash message. Using
|
108 |
* custom elements allows you to fully customize how flash messages are generated.
|
109 |
*
|
110 |
* ```
|
111 |
* echo $this->Session->flash('flash', array('element' => 'my_custom_element'));
|
112 |
* ```
|
113 |
*
|
114 |
* If you want to use an element from a plugin for rendering your flash message you can do that using the
|
115 |
* plugin param:
|
116 |
*
|
117 |
* ```
|
118 |
* echo $this->Session->flash('flash', array(
|
119 |
* 'element' => 'my_custom_element',
|
120 |
* 'params' => array('plugin' => 'my_plugin')
|
121 |
* ));
|
122 |
* ```
|
123 |
*
|
124 |
* @param string $key The [Message.]key you are rendering in the view.
|
125 |
* @param array $attrs Additional attributes to use for the creation of this flash message.
|
126 |
* Supports the 'params', and 'element' keys that are used in the helper.
|
127 |
* @return string
