echo in view仅打印从控制器传递的数组中的第一个字符

Question

controller.php

 function post_action()
    {   
        $checkin=$_POST['checkin'];
        $checkout=$_POST['checkout'];
        $adult=$_POST['adult'];
        $child=$_POST['child'];


       $data['abc']= array("checkin"=>$checkin, "checkout"=>$checkout, "adult"=>$adult, "child"=> $child);
               $this->load->view('template/reservation_template',$data);
    }

                </td>
        </table>
    </form>




    </div>
    </div>

  <?php
    if(!empty($abc))    // this is where i am fetching data from controller to view.
    {

    foreach($abc as $g)
    {
        //var_dump($g);
    echo  $g["checkin"];
    }
    }

    ?>
 </div>

我很惊讶，为什么echo $ g [＆＃34; checkin＆＃34;]只给我一个来自输入字段的第一个字符，而var_dump给出输入的全部值。我做错了什么。请帮帮我。

首先，如果您通常想要在视图中回显数据，则可以调用模型来获取数据。

现在，您可以将$ _POST值放在一个数组中，如下所示：

$data = array(
"checkin"=>$checkin,
"checkout"=>$checkout,
"adult"=>$adult,
"child"=> $child
);

$this->load->view('template/reservation_template',$data);

一般来说，这些值来自这样的模型，就像在控制器中调用一样：

$data['values'] = $this->Model_name->get_some_data();

在视图中，您可以循环使用以下值：

foreach($values as $value)
{
   echo $value['checkin];
}
