Pass variable from controller to model (beforeSave) (Upload Field) CakePHP - cakephp

Question

I really need to know this issue to finish my work.
Here I'll give a example envolving model and controller.
I want to pass $final_name from controller to beforeSave() of my model
public function admin_add() {
if($this->request->is('post')) {
if($this->data['Client']['file']['tmp_name'] != '') {
// Upload block
$tmp_file = $this->data['Client']['file']['tmp_name'];
$file = new File($tmp_file);
if($file->mime() == "image/jpeg" or "image/png") {
$ext = explode('.', $this->data['Client']['file']['name']);
$name = md5($this->data['Client']['file']['name']);
$file->copy(IMG_DIR . 'portfolio\\' . $name . '.' . end($ext));
$final_name = $name . "." . end($ext); // File name with extension
}
// If save
if($this->Client->save($this->request->data)) {
$this->Session->setFlash('Client cadastrado com sucesso!', 'admin_flash');
}
}
}
}
In my client model
public function beforeSave($options = array()) {
if($this->data['Client']['file']['name'] != null) {
$this->data['Client']['file'] = $final_name;
}
return parent::beforeSave($options);
}

Answer 1

In Controller
$this->request->data['Client']['final_name'] = $name . "." . end($ext);
In Model
public function beforeSave($options = array()) {
if($this->data['Client']['file']['name'] != null) {
$this->data['Client']['file'] = $this->data['Client']['final_name'];
}
return parent::beforeSave($options);
}
Update for CakePHP3
Pass variable from controller to table beforeSave, afterSave ?
// Examples
// In Controller
$this->Article->save($data, ['passVariable' => 'passedData']);
// in Table
public function beforeSave(Event $event, EntityInterface $entity, ArrayObject $options)
{
if (isset($options['passVariable'])) {
// implement your code
}
}

But good place to modify data before save like asked in question are:
