Getter方法无法访问自己的属性

Question

I have the following entity Model with property float $price.

When I create such a getter method:

public function _getPrice()
{
    return $this->price*100;
}

It keeps giving me the following error:

Undefined property: App\Model\Entity\Model::$price

What's the problem?

Answer 1

You are essentially trying to access a getter method from within itself.

In order for this to work, try rewriting it as follows:

public function _getPrice()
{
    return $this->_properties['price'] * 100;
}
