I'm trying to override parent construct class in child class by following way but it's not success !
Parent class:
class Base extends \Core\Model
{
/**
* Error messages
*
* @var array
*/
public $errors = [];
public $errorMsg = '';
/**
* Class constructor
*
* @param array $data initial property values
*
* @return void
*/
public function __construct($data = [])
{
foreach ($data as $key => $value) {
$this->$key = $value;
};
}
}
Child class :
class Visit extends Base
{
/**
* Error messages
*
* @var array
*/
public $subscribe;
/**
* Class constructor
*
* @param array $data initial property values
*
* @return void
*/
public function __construct()
{
parent::__construct($data = []);
$this->subscribe = new Subscribe();
}
}
Please note above code it's not my full code ( too long ), I've just copy construct to avoid misunderstanding.
The data comes from a form in controller ($_POST), so when I run the above I got the following:
Message: 'Undefined property: App\Models\Visit::$phone'
Which mean parent construct didn't work after overriding !
Hope it's clear and thanks in advance.
Answer
The calling side tries to construct object from your class with array of arguments and suppose that they will become a public properties of this object as it is done in Base constructor.
If it is done like this $a=new Base(['phone'=>'123']) then $a->phone will be available.
But your constructor does not use any arguments, while it should forward them to parent.
Try this way:
public function __construct($data=[])
{
parent::__construct($data);
$this->subscribe = new Subscribe();
}
