Codeigniter将数据从控制器传递到view / w复杂数组

问题描述：

Checked to see if this is a duplicate, it would appear so but the other questions I've found do not answer this question.

I'm using CodeIgniter and I would like to access a 'complex' array (from a db) in my view.

Codeigniter passing data from controller to view The link answers part of my question, but it's a simple array like so:

In the controller:

$data = array(
    'title' => 'title 1',
    'user' => 'user 1'
);
$this->layout->view('example/test', $data);

In the view

echo $title.$user;

So all of that I do get, however what if the array was a little more complicated like:

$data = array(
   array(
    'title' => 'title 1',
    'user' => 'user 1'
   ),
   array(
    'title' => 'title 2',
    'user' => 'user 2'
   )
);

How can I access this kind of array in my view?

检查这是否重复，它会出现，但我发现的其他问题没有回答这个问题。 p>

我正在使用CodeIgniter，我想在我的视图中访问一个'复杂'数组（来自数据库）。 p>

Codeigniter将数据从控制器传递到视图链接回答了我的部分内容问题，但它是一个简单的数组，如下所示： p>

在控制器中： strong> p>

  $ data = array  （
'标题'=＆gt;'标题1'，
'用户'=＆gt;'用户1'
）; 
 $ this-＆gt; layout-＆gt; view（'example / test'，$ 数据）; 
  code>  pre> 
 
  在视图中 strong>  p> 
 
 
  echo $ title。$ user  ; 
  code>  pre> 
 
 所以我得到了所有这些，但是如果数组有点复杂如下： p> 
 
 
  $ data = array（
 array（
'title'=＆gt;'title 1'，
'user'=＆gt;'user 1'
  ），
 array（
'title'=＆gt;  'title 2'，
'user'=＆gt;  'user 2'
）
）; 
  code>  pre> 
 
 如何在视图中访问此类数组？ p> 
  div>

答

you should wrap the outer array and give it a key like this

$data = array(
   'myAwesomeArray' => array(
       array(
        'title' => 'title 1',
        'user' => 'user 1'
       ),
       array(
        'title' => 'title 2',
        'user' => 'user 2'
       )
   )
);

you should be able to access your data in the view using $myAwesomeArray

答

Use this in controller :

$data = array(
                   array(
                    'title' => 'title 1',
                    'user' => 'user 1'
                   ),
                   array(
                    'title' => 'title 2',
                    'user' => 'user 2'
                   )
                );
        $content = array('data'=> $data);
$this->layout->view('example/test', $data);

In view file :

foreach($data as $key=>$val)
{
  echo  $val['title'].$val['user'];
}

答

You can simply try this:

    $data['content'] = array(
                  array(
                        'title' => 'title 1',
                         'user' => 'user 1'
                        ),
                  array(
                         'title' => 'title 2',
                          ' user' => 'user 2'
                         )
                 );

$this->load->view('example/test',$data);

In View:

 foreach($content as $value)://to traverse the data array ....

 endforeach;
