Question

在运行第三方php应用程序时，我收到此类警告：Warning: DOMNode::cloneNode(): ID mainBodyArea already defined in /libraries/content-extractor/ContentExtractor.php on line 676

接着是另一个警告： Warning: Cannot modify header information - headers already sent by (output started at libraries/content-extractor/ContentExtractor.php:676) in libraries/feedwriter/FeedWriter.php on line 103

ContentExtractor.php中的行近676 ..

if (isset($this->body)) $this->body = $this->body->cloneNode(true); $success = $this->readability->init();
第103行附近的FeedWriter.php中的
行

header('Content-type: application/json; charset=UTF-8'); $this->json = new stdClass();

我被困在这里几个小时，因为如果这样。我是php概念的新手。请帮帮我。

我没有完全得到这个错误，但刚刚修复了一些非常相似的东西，我的。

DOMNode::cloneNode() [<a href='domnode.clonenode'>domnode.clonenode</a>]: ID header already defined in dompdf/include/frame_decorator.cls.php on line 128

我正在使用html制作pdf：

$html = '<html><head>
  <style>
    @page { font-family:Arial, Helvetica, sans-serif; margin:0px; }
    #header { position: fixed; left: 0px; top: 50px; right: 0px; height: 70px; text-align: center; }
    #footer { position: fixed; left: 0px; bottom: 50px; right: 0px; height: 70px; text-align: center; }
    #content { position: fixed; left: 0px; top: 160px; right: 0px; text-align:center; height:934px; width:934px; }
  </style>
</head>
<body>
  <div id="header">
    header content
  </div>
  <div id="content">
    main content
  </div>
  <div id="footer">
    footer content
  </div>
</body>
</html>';

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$pdf = $dompdf->output();

要解决问题，我所做的就是将id更改为类：

$html = '<html><head>
  <style>
    @page { font-family:Arial, Helvetica, sans-serif; margin:0px; }
    .header { position: fixed; left: 0px; top: 50px; right: 0px; height: 70px; text-align: center; }
    .footer { position: fixed; left: 0px; bottom: 50px; right: 0px; height: 70px; text-align: center; }
    .content { position: fixed; left: 0px; top: 160px; right: 0px; text-align:center; height:934px; width:934px; }
  </style>
</head>
<body>
  <div class="header">
    header content
  </div>
  <div class="content">
    main content
  </div>
  <div class="footer">
    footer content
  </div>
</body>
</html>';

我希望这可以帮助或让您更接近解决问题！
