Read value from query string in CodeIgniter

Question

I am new to CodeIgniter. I am trying to read values from query string in conventional method not segment.

This is my url.

http://localhost/Voyager/Main/UserActivation/?u=6df497644a10241cd89fad80f5c98496

Controller:

class Main extends CI_Controller{

     public function UserActivation()
    {
        $hash=$this->input->get('u', TRUE);
        log_message('debug', $hash, false); 
        $this->load->view('Main\view_userActivation');  
    }

}

I am trying to read value of 'u' in controller. But this isn't working. I am getting empty value in $hash variable.

Any help is appreciated.

@DanWhite. If you check properly you will find that one which you mention talks about getting values from segment. Issue which I have mentioned is different. Before taking efforts to ask a question I have scanned more than 4 pages of google search results for issue. — Dheeraj Kumar

Your Code should work. Just check you set $config['allow_get_array'] = TRUE; at your config.php andmake sure your url helper is loaded — Shaiful Islam

Codeigniter works with URI Segments. You pass the values straight in your URL, separated with / and you grab them with positions after base_url like

$this->uri->segment(3)

There's a config option that unsets the $_GET array, but only if you have decided to change it.
This is how it looks by default in application/config/config.php:

$config['allow_get_array'] = TRUE;

If you've changed it to false - switch it back to true. Other than that, there's no reason why this wouldn't work, by default.

you can do something like this

Method 01

class Main extends CI_Controller{

    public function UserActivation($u)
    {
        echo $u;
        die;
        $this->load->view('Main\view_userActivation');  
    }

}

Then URL should be

http://localhost/Voyager/Main/UserActivation/6df497644a10241cd89fad80f5c98496

Method 02

class Main extends CI_Controller{

    public function UserActivation()
    {
        $value = $this->uri->segment(3);
        echo $value;
        $this->load->view('Main\view_userActivation');  
    }

}

Are you sure Method2 will work for the link that OP used?

Remove the / from the last uri segment.

http://localhost/Voyager/Main/UserActivation?u=6df497644a10241cd89fad80f5c98496

Also, another thing. Why you have your uri controller and methods starting in uppercase? That shouldn't be that way.
