如何在同一个类-Codeigniter的另一个函数中使用函数的变量

Question

I want to assign the value of $Id from firstFunction to the variable $temp in secondFunction.

public function firstFunction()
{
    $Id = $_POST['quizID_click'];
}


public function secondFunction()
{
    $temp = ------;
}

Please let me know how to access $Id in secondFunction

If i understand correctly you want to pass only a variable inside the Controller functions, You can do it by throwing a flash like this:

    public function firstFunction()
    {
        $this->load->library('session');
        $Id = $_POST['quizID_click'];
        $this->session->set_flashdata('item', $Id);
    }


    public function secondFunction()
    {
        $myVar = $this->session->flashdata('item');
    }

Basically you temporary save the variable value as flashdata giving it a 'item' value 'item' can be anything. then the second controller looks for this flashdata and asigns it to $myVar
