Getting info from the pre_controller hook

[eluser]FinalFrag[/eluser]
Hi there,

I have a pre_controller hook that executes the function 'example' which looks like this:

Code:
function example() {

    return 'testvar';

}

Now my question is rather simple...
How can I access the return value (in this case testvar) in my controller?

Thnx

OFAPI + CodeIgniter

While using OFAPI(http://code.google.com/p/ofapi/) with phpBB3 together with CodeIgniter, I ran into some annoying problems and errors.

Here is what I did:

Code:
$this->load->library('xmlrpc');

          $this->xmlrpc->set_debug(TRUE);

          $this->xmlrpc->server(site_url('forums/ofapi/ofapi.php'), 80);

          $this->xmlrpc->method('logging.login');

          $loginInfo = array('Cayren','xxxxxxx');

          $request = $loginInfo;

          //$request = array('auth' => $loginInfo);

          $this->xmlrpc->request($request);

          if ( ! $this->xmlrpc->send_request())

          {

             $data["response"] = $this->xmlrpc->display_error();

          }

          else

          {

             $this->xmlrpc->method('members.getMembersList');

             $request = array('auth' => $loginInfo);

             $this->xmlrpc->request($request);

             if ( ! $this->xmlrpc->send_request())

             {

                $data["response"] = $this->xmlrpc->display_error();

             }

             else

             {

                $data["response"] = $this->xmlrpc->display_response();

             }

          }

and the error I get:

Code:
Severity: Notice

Message: Undefined offset: 0

Filename: libraries/Xmlrpc.php

Line Number: 627

Fatal error: Call to a member function serialize_class() on a non-object in /usr/home/mmo/framework/libraries/Xmlrpc.php on line 646

Any idea what the problem could be?

Validate Form Array

Hi

I have a form field array that I want to submit to a database. Is there a way that I can use the CI validation rules on this.

Currently I am experimenting with javascript but not having much luck.

Code:
function checkuploads(form) { 

    var file; 

    var q;

    for (i=0; i&lt;form.elements['partnumber[]'].length; i++)     {

        q=i+1;

        if (form.elements['partnumber[]'][i].value!= '') { 

            //file += form.elements['user_files[]'][i].value; 

            if (form.elements['location[]'][i].value='') {

                    alert("Enter Location in row"+q);

                    return false;

            }

            if (form.elements['qty[]'][i].value='') {

                    alert("Enter Qty in row"+q);

                    return false;

            }

        } 

        return true;

    } 

}

Exiting Controller

Posted by: El Forum - 09-02-2008, 12:56 AM - Replies (3)

[eluser]spider pig[/eluser]
I have created a form and my controller script validates it and builds an error message in the variable $errorMessage. I then test if $errorMessage is not NULL, I display the form again with an error box. I then want to exit the script:

Code:
// header displayed earlier in code

if ($errorMessage != NULL) {

    $row->al_error_message = $this->error->error_box($errorMessage);

    $this->load->view('newsletter_form', $row);

    $this->load->view('footer', $settings);

    exit;

}

However, nothing displays. Is there a way to output what is already passed to output before I exit?

Thanks

Difference between putting a library inside /libraries and /application/libraries

Posted by: El Forum - 09-01-2008, 11:57 PM - Replies (2)

	[eluser]geshan[/eluser] What is the difference between putting a library in /libraries and /application/libraries? Which is better? Why and how?

__construct

Posted by: El Forum - 09-01-2008, 06:36 PM - Replies (2)

	[eluser]jbads[/eluser] Do I have this right? If I put a function call to check authentication in the construct of my class, then I do not need to include that same check on the individual functions / controllers within that class? That authentication check will run before any controllers are accessed? Sorry for the dipshit question. Just wanna make sure my bases are covered.

problems with ajax

Hi, I'm new to CI as well as javascripts & AJAX. I have a noobie question about how to pass in a variable from the view's javascript and how to access it in the controller.

View's [removed]

Code:
var httpObj;

function checkName(username)

{

  httpObj = GetHttpObject();

  if(httpObj == null)

      {

          alert ("Browser does not support HTTP Request");

          return;

      }

  var url = &lt;?php echo base_url().'index.php/addaccount/username_check';?&gt;;

  url=url+"?q=" + username; 

  url=url+"&sid;="+Math.random();

  httpObj.onreadystatechange=callback_account;

  httpObj.open("GET",url,true);

  httpObj.send(null);

}

function callback_account()

{

 if (httpObj.readyState==4 || httpObj.readyState=="complete")

 { 

   alert(httpObj.responseText);

 }

} 

function GetHttpObject()

{

    var xmlHttp=null;

    try

     {

     // Firefox, Opera 8.0+, Safari

     xmlHttp=new XMLHttpRequest();

     }

    catch (e)

     {

     // Internet Explorer

     try

      {

      xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");

      }

     catch (e)

      {

      xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");

      }

     }

return xmlHttp;

}

[removed]

Controller's function:

Code:
function username_check()

   {

      echo($this->input->get('q'));

   }

So my question is can I actually pass in

Code:
"?q=" + username;

if I didn't activate query string in my config? If I can't, is there a way around this without using query strings?

My second question is how do I access that variable in controller after it's pass in?
Right now my username_check function returns blank.

Please let me know if there is anything unclear. Thanks.

Bypassing uri-specified controller method?

Posted by: El Forum - 09-01-2008, 04:15 PM - Replies (1)

	[eluser]Unknown[/eluser] New to CI, just a quick question... I handle user authentication in the constructor of the controller. If authentication fails, it should display the login form and not run the requested method. Without using _remap(), how can i prevent the requested method from being called automatically (from within the constructor). Hopefully I was clear enough. Thanks
