Hello guys, im new to the frameworks world and i choose the codeigniter to start. I saw the videos on the site and a few tutorials on the internet. Now im practicing, and im getting a error when im doing a insert to the database.

The error: Fatal error: Call to undefined method Pedidos::_assign_libraries() in C:\wamp\www\codeigniter\system\libraries\Loader.php on line 185

Controller

Code:
class Pedidos extends Controller{

    function Pedidos(){

        parent::Controller();

    }

    function index(){

        $this->load->view('pedidos');

    }

    function enviar(){

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

        $nome = $this->input->post('nome');

        $email = $this->input->post('email');

        $pedido = $this->input->post('pedido');

        $this->Pedidos_model->enviarPedido($nome,$email,$pedido);

    }

}

Model

Code:
class Pedidos_model extends Model{

    function Pedidos_model(){

        parent::Model();

    }

    function enviarPedido($nome,$email,$pedido){

        $this->db->query("INSERT INTO pedidos (nome,email,pedido) VALUES ('$nome','$email','$pedido')");

    }

}

View

Code:
&lt;html&gt;

&lt;head&gt;

    &lt;meta http-equiv="content-type" content="text/html; charset=iso-8859-1" /&gt;

    &lt;meta name="author" content="Tomer Simis" /&gt;

    &lt;title&gt;Pedidos&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;form action="enviar" name="enviar" method="post" enctype="text/plain"&gt;

<p>

<label>Nome

&lt;input type="text" name="nome" maxlength="20" /&gt;

</label><br />

</p>

<p>

<label>Email

&lt;input type="text" name="email" maxlength="50" /&gt;

</label><br />

</p>

</p>

&lt;input type="submit" value="Enviar pedido" /&gt;

Instead of This code

Code:
function enviar(){

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

        $nome = $this->input->post('nome');

        $email = $this->input->post('email');

        $pedido = $this->input->post('pedido');

        $this->Pedidos_model->enviarPedido($nome,$email,$pedido);

    }

Try this and see if this work first

Code:
function enviar(){

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

        $nome = $_POST['nome'];

        $email = $_POST['email'];

        $pedido = $_POST['pedido'];

        $this->Pedidos_model->enviarPedido($nome,$email,$pedido);

    }

Your code has a lot needs to modify but try using some core php stuffs first

It seems that you have accidentally altered the core model class, which is where that method exists.

I've found a solution for the bug on the codeigniter bug tracker. I deleted the line 185 on the Loader class and the error stopped. Now im getting another error:

Code:
A PHP Error was encountered

Severity: Notice

Message: Undefined property: Pedidos::$PedidosModel

Filename: controllers/pedidos.php

Line Number: 20

Fatal error: Call to a member function enviarPedido() on a non-object in C:\wamp\www\codeigniter\system\application\controllers\pedidos.php on line 20

And before this error, i was getting another error: undefined index when i was posting, so i moved the POST vars to the model and the error stopped.

PS: I have changed the "Pedidos" model name for "PedidosModel", and the filename for "pedidosmodel.php"

Please guys, help me

Yes - removing the _assign_libraries() call from the core Loader class is likely to break other things.

The problem here is that you're experiencing a unique problem. This is why we tend to think it's something you've changed or done, rather than something wrong with the CI files.

Hmm, I was about to suggest you go through the same process again, only this time checking each time you add a new file, or at least confirming the basic system is working, but re-scanning your original question again I see that this bit might be a problem:

Code:
// controller ...

    function enviar(){

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

Code:
// model ...

class Pedidos_model extends Model{

In your controller, you really need to load the name of your model - in this case Pedidos_model and not the name of your controller (pedidos).

Try changing your controller to:

Code:
$this->load->model('Pedidos_model');

I just had the same error, and it turned out that I was calling a model, and the model file did exist, but had the wrong model name:

file: orders.php

class Not_orders extends Model {
//...
}

I was getting something similar. My error was:
codeigniter Fatal error: Call to undefined method About_model::_assign_libraries() on line 185

but then i realized that my About_model class did not extend the Model class. So if you haven't checked already, check to make sure your model is extending the Model class.
