如何验证视频上传文件大小

Question

我需要验证CodeIgniter中的视频上传大小限制（在服务器端）。

我想通过数组验证：

array('field' => 'd_video',
    'label' => 'Doctor Video',
    'rules' => 'required|file_allowed_type[media]|upload_max_filesize[3072]')

Answer 1

根据CI Document应该如下：

$config['upload_path']   = '/uploads/';
$config['allowed_types'] = 'mpeg|avi|wmv';
$config['max_size']      = '2048'; // File Size in KB

$this->load->library('upload', $config);
$this->upload->initialize($config);

if($this->upload->do_upload('d_video'))
{
   // Upload Success
}
else
{
   echo $this->upload->display_errors();
}
