一切正常，但它說嚴重性：通知消息：未定義的變量：類別

Question

//controller: 
private function getAll() { 

    $data['categories'] = $this->registrant_model->getAllDepartment(); 
    $this->load->view('SystemAdminUser/registrant', $data); 

} 

//model: 
public function getAllDepartment() { 
    $this->db->select('*')->from('patient_db'); 
    $query = $this->db->get(); 
    return $query->result_array(); 

} 


//view: 
<?php foreach($categories as $c):?> 
    <tr> 
     <td><?php echo $c['id'];?></td> 
     <td><?php echo $c['phone'];?></td> 
     <td><?php echo $c['name'];?></td> 
    </tr> 
<?php endforeach;?> 

這是代碼。每次它說爲foreach提供的未定義變量和無效參數。請幫助

你需要傳遞$data陣列控制器從

$data['categories'] = $this->registrant_model->getAllDepartment(); 
$this->load->view('SystemAdminUser/registrant', $data);// pass $data to view
