mPDF實時上傳不起作用

Question

我一直在嘗試上傳一個mpdf生成的文件，現在我遇到的問題是它沒有放在我想要的目錄中。

我的結構是這樣的：

- 應用 -

-cgi-bin-

-files- -system-

-user_guide-

這裏的代碼：

function save_answers() 
{ 
    $this->load->library('mpdf'); 
    $mpdf=new mPDF(); 
    $user = $this->ion_auth->get_user(); 
    $uid = $user->id; 
    $lid = $this->input->post('looper'); 
    $html = ''; 
    $html .= 'Examinee: '.$user->username; 
    $html .= '<br />Date taken: '. date('Y-m-d').'<br />'; 
    for ($i=1; $i<=$lid; $i++) { 
     $html .= 'Question: '.$this->input->post('qname_'.$i).'<br />'; 
     $html .= 'Answer: '.$this->input->post('answer_'.$i).'<br /><br />'; 

    } 
    $html .= '<small><i>End of monthly exam. Ths is a system_generated item.</i></small>'; 

    $data['xid'] = $this->input->post('xid'); 
    $data['uid'] = $this->input->post('uid'); 
    $mpdf->WriteHTML($html); 
    $filename = mt_rand(11111, 22222) + $uid; 

    $data['pdf'] = $mpdf->Output($filename, 'D'); 

    $config['upload_path'] = 'files/'; 

    $config['max_size'] = '1000'; 
    $config['max_width'] = '1920'; 
    $config['max_height'] = '1280';      

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

    if(!$this->upload->do_upload()) echo $this->upload->display_errors(); 
    else { 
     $fInfo = $this->upload->data(); 
     #$this->_createThumbnail($fInfo['file_name']); 

     $data['uploadInfo'] = $fInfo; 
     $data['file_name'] = $filename; 
     #$data['thumbnail_name'] = $fInfo['raw_name'] . '_thumb' . $fInfo['file_ext']; 
     if($this->Exam_model->score_updater($data)) { 
      $this->session->set_flashdata('msg_success', 'Successfully taken and saved'); 
      redirect('home', 'refresh'); 
     } 

    } 
    $mpdf->Output($filename, 'D'); 


}

嘗試將您的upload_path更改爲絕對，而不是相對。

$config['upload_path'] = '/full/path/to/your/files';
