how to sent parameter in redirect - php codeigniter

Question

the following code gives me an error. I want to call a function and pass a parameter to it with php codeigniter.

redirect(base_url() . 'MainController/Student_Login($user_email)')

here MainController is the Controller name, Student_Login is the function $user_email is a variable that holds the user email id. I have also tried sending it through url. e.g.

redirect(base_url() . 'MainController/Student_Login/.$user_email.')

Please Help.

Answer 1

There is no need of adding base_url with redirect.

Just try

redirect('mainController/Student_Login/'.$user_email)

when user_email you will receive as argument in student_Login funciton

Answer 2

You can pass it over session. If you want it available next request only, put it in session flash data.

First controller

public function method1()
{
    // if not loaded session library in APPPATH . 'config/autoload.php' load it in here

    $this->session->set_flashdata('user_email', $user_email);

    redirect('secondcontroller/method2', 'refresh');
}

Second controller

public function method2()
{
    // if not loaded session library in APPPATH . 'config/autoload.php' load it in here

    $user_data = $this->session->flashdata('user_email');

    // when flash data is set, after this request it will be unset from $_SESSION array
}

Answer 3

Use it as with out base_url()

redirect('MainController/Student_Login/'.$user_email);

And in method you get it using

function Student_Login($user_email){
    echo $user_email;
    //...
}
