Link for cakephp file download

I ran into a problem that I’ve been trying to solve for more than two days: I created a website using cakephp and everything works fine, but I got stuck when I tried to implement download links to saved files under APP_DIR/someFolder/someFile.zip.

How to set download links to files inside someFolder? I often came across "Media Views", I tried to implement them, but so far I have not been successful.

Also, is there no easier way to make files downloadable?

Multimedia views have been deprecated since version 2.3. Instead, use File Upload .

Check out this minimal example in the controller:

public function download($id) {
    $path = $this->YourModel->aMagicFunctionThatReturnsThePathToYourFile($id);
    $this->response->file($path, array(
        'download' => true,
        'name' => 'the name of the file as it should appear on the client\ computer',
    ));
    return $this->response;
}

$this->response->file APP. $this->response->file('someFolder' . DS . 'someFile.zip') APP/someFolder/someFile.zip.

" " CakePHP 2.0. .

CakePHP, Media Views, . Media Views (Cookbook).

:

public function download($id) {
    $this->viewClass = 'Media';
    $path = $this->YourModel->aMagicFunctionThatReturnsThePathToYourFile($id);
    // in this example $path should hold the filename but a trailing slash
    $params = array(
        'id' => 'someFile.zip',
        'name' => 'the name of the file as it should appear on the client\ computer',
        'download' => true,
        'extension' => 'zip',
        'path' => $path
    );
    $this->set($params);
}
