Question

我遇到一个问题，在/ uploads中出现名称为69398f524b17741a34ee3f77234797e2.jpg等的文件。似乎该文件被编码为随机MD5。

在库Upload.php中，我发现MD5用于在结束文件名中添加一个数字，如果它发现具有相同名称的文件已经存在。

在模型中我有这样的代码：

 function do_upload()
   {

     $config['upload_path']     = './uploads/';
     $config['allowed_types']   = 'gif|jpg|png|jpeg';
     $config['max_size']        = '1000';
     $config['max_width']       = '2024';
     $config['max_height']      = '2024';
     $config['encrypt_name'] = TRUE;

    //var_dump($config);

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

     $temp_files = $_FILES;
    // var_dump($temp_files);
    // echo "files";

    // var_dump($_FILES);

     $count = count ($_FILES['userfile']['name']);

    for ($i=0; $i<=$count-1; $i++){

     $_FILES['file'] = array (
                'name'=>$temp_files['userfile']['name'][$i],
                'type'=>$temp_files['userfile']['type'][$i],
                'tmp_name'=>$temp_files['userfile']['tmp_name'][$i],
                'error'=>$temp_files['userfile']['error'][$i],
                'size'=>$temp_files['userfile']['size'][$i]);
    unset($_FILES['userfile']);         
    var_dump($_FILES);

    if ( ! $this->upload->do_upload('file'))
    {
        $error = array('error' => $this->upload->display_errors());

        $this->load->view('insert', $error);
    }
    else
    {


        $this->upload->do_upload('file');

        $tmp_data = $this->upload->data();
               echo "<hr>";   
         var_dump($tmp_data);   

    }//end else

    }//end for
    }//end do_upload

var_dump（$ _ FILES）return

   array (size=1)
         'file' => 
                 array (size=5)
                      'name' => string 'Desert.jpg' (length=10)
                      'type' => string 'image/jpeg' (length=10)

                      'error' => int 0
                      'size' => int 845941

var_dump（$ tmp_data）return

     array (size=14)
           'file_name' => string '69398f524b17741a34ee3f77234797e2.jpg' (length=36)

Answer 1

而不是$config['encrypt_name'] = TRUE;写$config['encrypt_name'] = FALSE;
