笨：查看的foreach呼叫控制器

Question

Error:
A PHP Error was encountered

Severity: Notice

• Message: Undefined variable: calificacione
• Message: Invalid argument supplied for foreach()

---

• 有什麼不好？
• 在Controller變量創建：$data['calificacione']
• 並在視圖上調用foreach

筆者認爲：

<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> 

我的控制器

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

請查看以下上述可能性。

您是從模型或任何錯誤獲取數據。

var_dump($data['calificacione']); 
die; 
$data['_view'] = 'provedore/index'; 
$this->load->fullView('layouts/main',$data); 

請分享您的輸出，以便我們爲您提供幫助。

Answer 2

//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) 
} 

Answer 3

在模型

Provedore_modelget_all_provedores可能有一個像

function get_all_provedores ($argument) 
{ 
// your database query 
} 

一些參數，你did'nt履行這一說法
