【问题描述】：

我一直在尝试上传一个 mpdf 生成的文件，现在我遇到的问题是它没有将它放在我想要的目录中。

我的结构是这样的：

-应用程序-

-cgi-bin-

-文件- -系统-

-user_guide-

代码如下：

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');

【参考方案1】：

尝试将您的上传路径更改为绝对路径而不是相对路径。

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