将函数值传递给同一类中的另一个函数 [英] passing function values to another function in same class

问题描述

我想将函数值传递给同一类中的另一个函数，例如将一些值存储在变量中，然后在同一类中的另一个函数中调用此变量。

I want to pass function values to another function in the same class, like to store some values in a variable and then call this variable in another function in the same class.

这是我的代码

public function ven_coupon()
    {
        if ($_POST) {
            $number = $_POST['coupon'];
            $query = $this->front->ven_coupon($number);
            if (count($query) <= 0 ) {
                echo "Not Valid";
            }
            $payment = $this->cart->total();
            $dis = $query['discount'];
            $name = $query['username'];
            $number = $query['number'];
            $discount['discount'] = ($payment*$dis)/100;
            $discount['data'] = $dis;
            $this->load->view('checkout',$discount);
        }
    }

    public function addcart()
    {
        $ven = $this->ven_coupon();
        echo $ven($name);
        echo $ven($dis);
        echo $ven($number);
    }

推荐答案

您可以创建字段（变量），则需要在函数外部使用它们，然后使用 this 关键字使用它们。例如：

You could create the fields(variables) you need outside the function then use them using the this keyword. For example:

private $dis;
private $name;
private $number;

public function ven_coupon()
{
    if ($_POST) {
        $number = $_POST['coupon'];
        $query = $this->front->ven_coupon($number);
        if (count($query) <= 0 ) {
            echo "Not Valid";
        }
        $payment = $this->cart->total();
        $this->dis = $query['discount'];
        $this->name = $query['username'];
        $this->number = $query['number'];
        $discount['discount'] = ($payment*$dis)/100;
        $discount['data'] = $dis;
        $this->load->view('checkout',$discount);
    }
}


public function addcart()
{
    $ven = $this->ven_coupon();
    echo $this->name;
    echo $this->dis;
    echo $this->number;
}
