how display retrieve data in codeigniter

我的型号代码

public function retrivecat()
{
$query = $this->db->get(‘category’);
foreach ($query->result() as $row)
{
$data[] = $row->catname;
}
return $data;
}

我的控制器代码

function addPost()
{
$username = $this->session->userdata(‘username’);
$data = array(
‘pageTitle’ => ‘?§?±?3?§ù? ù…?·ù??¨’,
‘username’ => $username
);
$this->load->model(‘category’);
$data = $this->category->retrivecat();
$this->load->view(‘dashboard/post’,$data);
}

我的查看代码：

1 2	print_r($data); exit();

但是，这不起作用并显示：

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: data

Filename: dashboard/post.php

Line Number: 72

要将变量传递到视图中，您必须这样做：

function addPost()
{
$username = $this->session->userdata(‘username’);
$data = array(
‘pageTitle’ => ‘?§?±?3?§ù? ù…?·ù??¨’,
‘username’ => $username
);
$this->load->model(‘category’);
$data[‘variable’] = $this->category->retrivecat();
$this->load->view(‘dashboard/post’,$data);
}

然后在视图中做 print_r($variable);
