[FIXED] How to check if a parameter is null or has a value in codeigniter?

Issue

I am new to codeigniter. I want to run code based on whether the parameter value exists or not.

For example:

If I hit this url

http://localhost/myproject/index.php/1

code works perfectly as it has a parameter value

But if I hit this url

http://localhost/myproject/index.php/

I get error of too few arguments to the function in index()

Here is my index function in the controller:

public function index($id)
{
    if(isset($id))
    {
        //do some code
    }
    else
    {
        $this->load->view('login');
    }
}

Solution

Try this public function index($id = '')

public function index($id = '')
{
    if(!empty($id)){
        //Coding...
    }
    else{
        return $this->load->view('login');
    }
}
