Drop Down Menus & Validation

Posted by: El Forum - 08-26-2007, 08:39 AM - No Replies

	[eluser]Kemik[/eluser] Hello, How is the best way of protecting data from being submitted using a drop down menu? I posted my site to be tested on PHP Freaks and found that by saving the source of files, they could edit the drop down menu values and then using their new html file to submit any value they liked using my drop down fields. Could I just use normal rules like I do with text fields?

Calling Model Function in the View

Posted by: El Forum - 08-26-2007, 07:14 AM - No Replies

[eluser]Gnurpreet[/eluser]
Hi,
Can I call a function from a model to directly into the view? I have loaded it in the controller, but want to call the function in the view only.

Here's the situation...
I have a showing a piece of content in the view, but I have to show the name of the user who posted it (which comes from a different table and thus a different user model ). Now, in the view, I have the ID of the user, but I want to show his username.

This in the view does not work

Code:
echo "Posted by ".$this->User_model->get_username($list->user_id);

I have loaded the view in the controller, but still.

Here is the model code

Code:
class User_model extends Model

{

    function User_model()

    {

        parent::Model();

    }

    function get_username($user_id)

    {

        $this->db->where("id", $user_id);

        $user_data = $this->db->get("user");

        return($user_data['username']);        

    }

}

any pointers?

Embedding Wordpress in CI

Posted by: El Forum - 08-25-2007, 07:13 PM - No Replies

[eluser]Unknown[/eluser]
I'm currently in the process of rewriting my site using CI. In connection with that I decided to use an embedded instance of Wordpress for the site news. I have been following the instructions at http://www.shooflydesign.org/buzz/past/e...press.html on how to embed WP.

The above link explains how to include an internal WP file using require(), and then call the global functions of WP to render blog-entries and get data from the WP framework.

It works fine as long as I follow the example given, and keep the code out of reach of CI.

In CI, it seems that no matter how I include the internal WP file, I do not get access to the WP functions. I've confirmed that the file actually gets executed, but it seems that CI somehow prevents me from calling the functions. If I move all the code to an external file, which I then execute by including it from a CI - file (eg. a view), everything works perfectly. Unfortunately, this has the disadvantage of completely isolating CI from my code, which prevents me from passing parameters between WP and CI!

Does anyone know if it is possible to do what I outlined in the first paragraph within CI? Has anyone else attempted to do a similar integration of another application into CI? Hope someone here will be able to help. Thanks in advance.

Fatal error: Call to a member function row() on a non-object

[eluser]BrandonDurham[/eluser]
Why would this be happening here?

Code:
$sql = "UPDATE prizes SET

    email                 = '$email',

    fname                = '$first_name',

    lname                = '$last_name',

    address1            = '$address',

    address2             = '$add_address',

    city                 = '$city',

    state                 = '$state',

    zip                  = '$zip',

    date_submitted      = '$date_submitted',

    opt_in                 = '$opt_in',

    company             = '$company',

    day_phone            = '$day_phone',

    evening_phone        = '$evening_phone'

    WHERE id            = '8'

";

$query = $this->db->query($sql);

$row = $query->row();

Here's the full error:

Quote:Fatal error: Call to a member function row() on a non-object in /Users/Deefee/Documents/Sites/073MHG232/system/application/models/db_functions.php on line 88

Retrieving the default controller config item

Posted by: El Forum - 08-25-2007, 04:54 PM - No Replies

[eluser]NemetraL[/eluser]
Hello,

The problem is: I'd need to retrieve

Code:
$route['default_controller'];

from a post-controller-constructor hook.

There's the raw way, which consists in copying the Router library code directly inside the hook:

Code:
// Load the routes.php file.

@include(APPPATH.'config/routes'.EXT);

$this->routes = ( ! isset($route) OR ! is_array($route)) ? array() : $route;

unset($route);

The point is: this file has already been loaded and the class has already been created (in the system/codeigniter/CodeIgniter.php file, under the name $RTR).

But once the controller is loaded, I can't find it anymore :-S

Any idea?

How get referring URL?

Posted by: El Forum - 08-25-2007, 12:44 PM - No Replies

	[eluser]brigham[/eluser] What's the best way to get the URL of the page "before" the current page? E.g., 1. User tries to go to page X, but page X requires a logged in user, so 2. Page X bounces user to the login page. 3. The login page, upon completion, sends user on to page X. I assume that there is an elegant solution to this...

single ds with MVC?

Posted by: El Forum - 08-25-2007, 12:40 PM - No Replies

[eluser]Matthew90[/eluser]
Hello,

today I have started to work with CI and my first impression is really good :-)
As this is my first job with a framework, the MVC-Model and strict OOP-Programming is new for me.
Now I have an problem with the MVC-Model.
It concerns the following...
I want to return a single data set... without oop no problem:

Code:
$this->db->where(array('id' => $this->uri->segment(3)));

        $query = $this->db->get('projects');

        if ($query->num_rows() > 0) {

            $row = $query->row(); 

               echo $row->id;

               echo $row->description;

           //...

        }

But how can I do it, when I want to work with the model class?
I tried a lot of iddeas but without a result...
At the moment my code is as followed:

project_model.php

Code:
function get_requested_project($where)

    {

        $this->db->where($where);

        $query = $this->db->get('projects');

        if ($query->num_rows() > 0) {

            return $query->row();

        }

        else {

            return false;

        }

    }

admin.php

Code:
function insert_project()

    {

        $this->load->model('project_model');

        $row=$this->project_model->get_project(array('id' => $this->uri->segment(3)));

        if ($row != false) {

               echo $row->id;

               echo $row->description;

            $this->load->view('project_insert',$data);

        }

I hope you know what I mean in spite of my bad English and I look forward to get an answer ;-)

Greetings

Matthew

Validate Dates & Times

Posted by: El Forum - 08-25-2007, 11:40 AM - No Replies

	[eluser]Kemik[/eluser] Hello, What's the best way to validate a date and time with CodeIgniter? At the moment I'm using Rapyd's dateField but I'm willing to build a form using CI's form helper instead if I have to. Thanks.

CI form not posting. on server, but working on localhost. gives error 500

Posted by: El Forum - 08-25-2007, 11:07 AM - No Replies

[eluser]rudydelhi[/eluser]
Hi,

I am configuring a new site on server 1and1.com. Made a simple login form with username/password and trying to post the values, but it gives a strange error error

Error 500 - Internal server error
The server encountered an unexpected condition which prevented it from fulfilling the request.

This same script works well on my localhost. Tried every possible change in the config file and the form path.

Can any someone please out with this problem.

Thanks,
Rudy
