如何驗證視頻上傳文件大小

Question

我需要驗證CodeIgniter中的視頻上傳大小限制（在服務器端）。

我想通過數組來驗證這一點：

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

Answer 1

根據CI Document應該像如下：

$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(); 
}
