我尝试通过这个模型（page_model.php）通过codeigniter中的活动记录来获取一些数据：

class Page_model extends CI_model{
    function __construct()
    {
        // Call the Model constructor
        parent::__construct();
    }
    function get_content($page){
        var_dump($page);
        $query = $this->db->get_where('pages', array('name' => $page));
        var_dump($query);
        if($query->num_rows()<1){
            echo $page;
            return FALSE;
        }
        else{
//          foreach($query->result() as $row){
//              $data[]=$row;
//          }
//          return $data;
    return $data=$query->result();

        }

    }
}

和 contents.php 视图：

<div class="contents">
<?php 
foreach($info as $p){
    $c= $p->content;
}
echo $c;


?>
</div>

pages.php 控制器：

<?php 
class Pages extends CI_controller{
    public function __construct(){
        parent::__construct();
        $this->load->model('page_model');
    }
    public function index($page){
        echo strlen("س");
        $data['info']=$this->page_model->get_content("ایران");
        var_dump($data['info']);
        $this->load->view('header',$data);
        $this->load->view('contents',$data);
        $this->load->view('footer');
    }

}

它给了我这个错误：

 PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

Filename: views/contents.php

Line Number: 3

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: c

Filename: views/contents.php

Line Number: 6

var_dump($page)：

string 'ایران' (length=10)

var_dump($query)：

object(CI_DB_mysql_result)[16]
  public 'conn_id' => resource(29, mysql link persistent)
  public 'result_id' => resource(32, mysql result)
  public 'result_array' => 
    array (size=0)
      empty
  public 'result_object' => 
    array (size=0)
      empty
  public 'custom_result_object' => 
    array (size=0)
      empty
  public 'current_row' => int 0
  public 'num_rows' => int 0
  public 'row_data' => null

var_dump（$信息）：

boolean false

但我有一个列名=“ایران”的记录，我将 permited_url_chars 设置为空。

谢谢你
