如何在codeigniter中顯示sql表字段

Question

我試圖在索引頁面上顯示我的「項目」表的字段內容，但似乎無法讓它工作。我在這裏做錯了什麼？

型號：

public function prodView() { 
      $sql = 'SELECT * FROM projects'; 
      $query = $this->db->query($sql); 
      return $query->result(); 
} 

控制器：

public function index() { 
     $this->load->model('main_model'); 
     $data ['query'] = $this->main_model->prodView(); 
     $this->load_view('/index', $data); 
} 

查看：

<?php foreach($query as $row): ?> 
    <tr> 
    <td><?php echo $row->project_name; ?></td> 
    </tr> 
<?php endforeach; ?>

型號

public function prodView() { 
    $result = array(); 
    $this->db->select("*")->from("projects"); 
    $query = $this->db->get(); 
    if($query->num_rows() > 0){ 
    $result = $query->result_array(); 
    } 
    return $result; 
} 

控制器

public function index() { 
    $this->load->model('main_model'); 
    $data ['query'] = $this->main_model->prodView(); 
    $this->load->view('missio/index', $data); 
} 

查看

<?php foreach($query as $row): ?> 
    <tr> 
    <td><?php echo $row['project_name']; ?></td> 
    </tr> 
<?php endforeach; ?>
