|
||
| 23 | * Media View provides a custom view implementation for sending files to visitors. Its great
|
||
| 24 | * for making the response of a controller action be a file that is saved somewhere on the filesystem.
|
||
| 25 | *
|
||
| 26 | * An example use comes from the CakePHP internals. MediaView is used to serve plugin and theme assets,
|
||
| 27 | * as they are not normally accessible from an application's webroot. Unlike other views, MediaView
|
||
| 28 | * uses several viewVars that have special meaning:
|
||
| 29 | *
|
||
| 30 | * - `id` The filename on the server's filesystem, including extension.
|
||
| 31 | * - `name` The filename that will be sent to the user, specified without the extension.
|
||
| 32 | * - `download` Set to true to set a `Content-Disposition` header. This is ideal for file downloads.
|
||
| 33 | * - `path` The absolute path, including the trailing / on the server's filesystem to `id`.
|
||
| 34 | * - `mimeType` The mime type of the file if CakeResponse doesn't know about it.
|
||
| 35 | * Must be an associative array with extension as key and mime type as value eg. array('ini' => 'text/plain')
|
||
| 36 | *
|
||
| 37 | * ### Usage
|
||
| 38 | *
|
||
| 39 | * ```
|
||
| 40 | * class ExampleController extends AppController {
|
||
| 41 | * public function download() {
|
||
| 42 | * $this->viewClass = 'Media';
|
||
| 43 | * $params = array(
|
||
| 44 | * 'id' => 'example.zip',
|
||
| 45 | * 'name' => 'example',
|
||
| 46 | * 'download' => true,
|
||
| 47 | * 'extension' => 'zip',
|
||
| 48 | * 'path' => APP . 'files' . DS
|
||
| 49 | * );
|
||
| 50 | * $this->set($params);
|
||
| 51 | * }
|
||
| 52 | * }
|
||
| 53 | * ```
|
||
| 54 | *
|
||
| 55 | * @package Cake.View
|
||
| 56 | * @deprecated 3.0.0 Deprecated since version 2.3, use CakeResponse::file() instead
