Codeigniter: View foreach call Controller - codeigniter

Question

Error:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: calificacione
Message: Invalid argument supplied for foreach()
what is wrong?
In Controller the variable is created: $data['calificacione']
And in the view is called on foreach
My View:
<table class="table table-condensed table-striped">
<thead>
<tr>
<th>Calificacione</th>
</tr>
</thead>
<tbody>
<?php
foreach ($calificacione as $key => $value) {
echo "<pre>";print_r($value);echo "</pre>";
}
?>
<tr>
<td><?php ?></td>
</tr>
<?php } ?>
</tbody>
</table>
My Controller
class Provedore extends CI_Controller{
function __construct()
{
parent::__construct();
$this->load->model(['Provedore_model','Provedor_calificacione_model','Provedor_calificacione_model','Personas_contato_model','Direcione_model']);
}
/*
* Listing of all provedores
*/
function index()
{
$data['provedores'] = $this->Provedore_model->get_all_provedores();
$data['calificacione'] = $this->Provedor_calificacione_model->get_all_provedor_calificaciones();
$data['_view'] = 'provedore/index';
$this->load->fullView('layouts/main',$data);
}

Answer 1

Please check below mentioned possibilities.
Are you getting data from model or any error.
var_dump($data['calificacione']);
die;
$data['_view'] = 'provedore/index';
$this->load->fullView('layouts/main',$data);
Please share your output so we can help you.

Answer 2

in your model Provedore_model get_all_provedores may has some arguments like
function get_all_provedores ($argument)
{
// your database query
}
and you did'nt fulfilling that argument

Answer 3

//try this
function index()
{
$provedores = $this->Provedore_model->get_all_provedores();
$data['provedores'] = $provedores;
$calificacione = $this->Provedor_calificacione_model->get_all_provedor_calificaciones();
$data['calificacione'] = $calificacione;
$this->load->view('layouts/main',$data)
$this->load->view('provedore/index',$data)
}
