What you mean ? View is a generated html displayed in borwser. If you want pass something to controller you have to made request to server. If you want to pass some data you have to make put/post request with form/params and get them in the controller.

Thanks for your prompt reply.

All Model properties are in the form. Currently, I have to extract myobjects properties via getPost individually, e.g. in the controller's saveAction function, I do: myobjects->prop1 = $this->request->getPost("prop1"); myobjects->prop2 = $this->request->getPost("prop2"); myobjects->prop3 = $this->request->getPost("prop3"); .......................

I was wondering if I could just do above in a single line: myobjects = $this->request->getPost("myobjects");

Thanks

Purpose: I don't wish to change the controller when database schema changes

Hey,

you can do something like

foreach ($this->request->getPost() as $key => $value) {
    $myobjects->$key = $value;
}

But i strongly recommend to limit the fields that can be modified this way if u are saving them in database.

For example a simple setup, like so:

$allowedFields = array('title', 'description');
foreach ($allowedFields as $field) { 
    $myobjects->$field = $this->request->getPost($field); 
}

You can also just get whole post without argument and when use whitelist when create/update entity.

Yeah Jurigag solution is even cleaner. Going to leave it as reference here in case someone needs it:

$robot = new Robots();
$robot->save(
    $_POST,
    array(
        'name',
        'type'
    )
);

Well still you shouldnt use $_POST array. Just use $this->request->getPost();
