Hello, I did an mvc application but I'm having trouble passing a controller variable to the view. My codes:
class Home extends Controller {
public function index() {
$user = $this->loadModel('usersModel');
$row = $user->getUserData(Session::get('user_id'));
$this->loadView('_templates/header');
$this->loadView('home/index');
$this->loadView('_templates/footer');
}
}
View:
<?php echo $user; ?>
I just solved the following: I changed the parameter $ data into object, so I was able to pass the user object
public function loadView($view, $data = null) {
if($data) {
foreach ($data as $key => $value) {
$this->{$key} = $value;
}
}
require APP . 'view/' . $view . '.php';
}
You can use extract combined with func_get_arg() that looks similar to some popular frameworks and use an anonymous function (requires php5.3) to avoid accessing the class scope, as in this answer:
This will prevent access to $this variables, so I recommend that you also use Type Hinting )
public function loadView($view, array $data = null)
{
$load = function ($data)
{
if (empty($data) === false) {
extract(func_get_arg(0));
}
require APP . 'view/' . $view . '.php';
};
$load($data);
$load = $data = NULL;
}
The access in the view will look like this (I believe):
$row = $user->getUserData(Session::get('user_id'));
$this->loadView('home/index', $row);
And in home/index.php and variable access will be something like (without the need of $this ):
<?php echo $user; ?>
