Controller Passing Varibles in URL

[eluser]bdshan[/eluser]
From the user guide:

If your URI contains more then two segments they will be passed to your function as parameters.

For example, lets say you have a URI like this:

example.com/index.php/products/shoes/sandals/123

Your function will be passed URI segments 3 and 4 ("sandals" and "123"):

I have a url that looks like this: index.php/lookup/stats/bdshan

So I am trying to call the stats function of the lookup controller with a value of 'bdshan'. Simple enough. Here is my controller:

Code:

<?php
    class Lookup extends Controller
    {
    function index()
    {
        echo 'No LFSID Selected';
    }

    function stats($name)
    {
        echo "Segment 3 is: " . $this->uri->segment(3);
        /*
        $sql = "SELECT S.lfsname, S.races_started, S.races_completed, S.laps_completed, S.yellow_flags, S.safety_rating
        FROM safety_stats S
        WHERE S.license_req = '" . $name . "'";
        $data['user'] = $query = $this->db->query($sql);
            $this->load->view('lookup', $data);
        */
    }

    }
?>

I have the echo statement in there just for testing what is getting passed to the function. If I take it out, and uncomment of query code, I get this error:

A PHP Error was encountered
Severity: Warning

Message: Missing argument 1 for Lookup:tats()

Filename: controllers/lookup.php

Line Number: 9

A PHP Error was encountered
Severity: Notice

Message: Undefined variable: name

Filename: controllers/lookup.php

Line Number: 15

Why isn't my function getting the variable passed to in from the uri?

Hi bdshan,

If you are trying to call the function in other function of the controller, you have to call it like this:

Code:

function_name($this->uri->segment(3))

where the function_name=stats and uri->segment is going to change the $name var in your function stats.

If you are trying to call the function as a page of the controller, you don't have to give it any parameters, as you can pass it through as uri->segment.

Hope this helps

Maybe you miss understood me, I am trying to call the page like this: http://localhost/tieredracing/index.php/...ats/bdshan

But I get this:

A PHP Error was encountered
Severity: Warning

Message: Missing argument 1 for Lookup:tats()

Filename: controllers/lookup.php

Line Number: 9

A PHP Error was encountered
Severity: Notice

Message: Undefined variable: name

Filename: controllers/lookup.php

Line Number: 15

From the errors I can tell that it is using the correct controller and function, but the 3rd uri segement is not getting passed to the function as the user guide states it should.

I got it working. I was reloading the uri library by accident. Once I removed it from autoload all is working as expected.

Thanks

Hi bdshan,

As i've told you, you can access the http://localhost/tieredracing/index.php/...ats/bdshan by running function stats() as a page of the controller.

In this case you don't have to give it any parameters... bdshan will be the uri->segment(3).

So i'll do it like this:

Code:

<?php
    class Lookup extends Controller
    {
    function index()
    {
        echo 'No LFSID Selected';
    }

    function stats()
    {
        /* If $name is the variable that you need to call uri->segment(3), it should be like this */

        $name = $this->uri->segment(3);

        $sql = "SELECT S.lfsname, S.races_started, S.races_completed, S.laps_completed, S.yellow_flags, S.safety_rating
        FROM safety_stats S
        WHERE S.license_req = '" . $name . "'";

        $data['user'] = $query = $this->db->query($sql);
            $this->load->view('lookup', $data);

    }

    }
?>

Tell me if is this work.

Good luck

Ive been looking for a solution of this problem but I found this thread very the same with my problem. I installed new version of codeigniter 1.7.1 with xampp 1.7.2, I dont know if these are compatible.

When I tried this URL:

http://localhost/mostrag/index.php?/most...9156824269

It outputs an error of: Message: Missing argument 1, which I think that my code is correct.

My class looks like this:

class Mostrag extends Controller {

// ...

public function profile($id)
{
// ...
}
}


I hope you can suggest what’s happening in my xampp and codeigniter. Im doing this in Windows Vista.


Thanks.
