上传 codeigniter 时重复文件到 2 份副本

Question

在 CodeIgniter 中，当我将文件上传到特定文件夹时，它会上传该文件的两个副本到文件夹。我的意思是，它重复文件，我不知道为什么。我该如何解决这个问题？谢谢。

控制器：

 $config['upload_path'] = './files/';
 $config['allowed_types'] = 'gif|jpg|png|jpeg|svg|rar|zip' ;
 $config['max_size'] = 220048;
 $config['encrypt_name'] = TRUE;

 $this->load->library('upload', $config, 'catalogupload3');
 // Create custom object for catalog upload
  $this->catalogupload3->initialize($config);
$this->catalogupload3->do_upload('userfile5');

if (!$this->catalogupload3->do_upload('userfile5')){

  $url_file = 'nofile' ;
  $file_name = 'false';
  $file_size = 'false';
}else {
  $this->catalogupload3->data();
  $url_file = $this->catalogupload3->data('file_name');
 $file_name = $_FILES['userfile5']['name'];
 $file_size = $_FILES['userfile5']['size'];
}

////

$config['upload_path'] = './files/32/';
 $config['allowed_types'] = 'gif|jpg|png|jpeg|svg|rar|zip' ;
 $config['max_size'] = 220048;
    $config['encrypt_name'] = TRUE;

 $this->load->library('upload', $config, 'catalogupload5');
 // Create custom object for catalog upload
  $this->catalogupload5->initialize($config);
$this->catalogupload5->do_upload('userfile7');

if (!$this->catalogupload5->do_upload('userfile7')){

  $url_file = 'nofile' ;
}else {
  $this->catalogupload5->data();
  $url_file_32 = $this->catalogupload5->data('file_name');
}

当然会上传两份因为你运行函数两次:

// first run
$this->catalogupload3->do_upload('userfile5');
// second run
if (!$this->catalogupload3->do_upload('userfile5'))

如果你想检查一次：

// this is enough it will run it and return a bool
if (!$this->catalogupload3->do_upload('userfile5'))
