codeigniter session data in two controller methods

Question

I have this two controller methods that both set session data

//Profile
public function profile()
{
    $this->session->set_userdata('title', 'some_value');
}
//KYC
public function kyc()
{
    $this->session->set_userdata('title', 'KYC');
    $this->load->view('basic/basic_app_views/kyc');
}

I am first loading the function kyc and using the session in my view

<title><?php echo $this->session->userdata('title'); ?></title>

I then load profile in my browser and refresh kyc but the value in kyc is still KYC like i had set in the kyc function.

How come title still has the value KYC even after resetting the value in another controller function?.

Answer 1

It is because each time you call your function it will set the userdata as it defines.

When try to set a title in a page, i suggest you to do this instead.

//Profile
public function profile()
{
    $data['title'] = 'Profile Page';
    $this->load->view('basic/basic_app_views/kyc', $data);
}
//KYC
public function kyc()
{
    $data['title'] = 'KYC Page';
    $this->load->view('basic/basic_app_views/kyc', $data);
}

then call it inside your kyc.php file.

<title><?php echo $title; ?></title>

hope that helps.

To see the change in the session title variable you would need to change up your code a little...

So your

//Profile
public function profile()
{
    $this->session->set_userdata('title', 'some_value');
}
//KYC
public function kyc()
{
    $this->session->set_userdata('title', 'KYC');
    $this->load->view('basic/basic_app_views/kyc');
}

To something like...

//Profile
public function profile()
{
    $this->session->set_userdata('title', 'some_value');
    $this->load->view('basic/basic_app_views/kyc');     // View the title value
}
//KYC
public function kyc()
{
    $this->session->set_userdata('title', 'KYC');
    $this->load->view('basic/basic_app_views/kyc');     // View the title value
}

That way you will see your value change. Each of your two methods individually change the value. But in your previous code only the kyc was displaying it.
