|
||
| 28 | * View, the V in the MVC triad. View interacts with Helpers and view variables passed
|
||
| 29 | * in from the controller to render the results of the controller action. Often this is HTML,
|
||
| 30 | * but can also take the form of JSON, XML, PDF's or streaming files.
|
||
| 31 | *
|
||
| 32 | * CakePHP uses a two-step-view pattern. This means that the view content is rendered first,
|
||
| 33 | * and then inserted into the selected layout. This also means you can pass data from the view to the
|
||
| 34 | * layout using `$this->set()`
|
||
| 35 | *
|
||
| 36 | * Since 2.1, the base View class also includes support for themes by default. Theme views are regular
|
||
| 37 | * view files that can provide unique HTML and static assets. If theme views are not found for the
|
||
| 38 | * current view the default app view files will be used. You can set `$this->theme = 'mytheme'`
|
||
| 39 | * in your Controller to use the Themes.
|
||
| 40 | *
|
||
| 41 | * Example of theme path with `$this->theme = 'SuperHot';` Would be `app/View/Themed/SuperHot/Posts`
