Question

我收到此错误：

捕获致命错误：传递给DOMNode :: appendChild（）的参数1必须是DOMNode的一个实例，null给定，在第304行的/home/emscompl/public_html/pdf_email/dompdf/include/table_frame_decorator.cls.php中调用并在第726行的/home/emscompl/public_html/pdf_email/dompdf/include/frame.cls.php中定义

这是dompdf代码。

<?php


/*$dir = dirname(__FILE__);
 require_once($dir.'/dompdf/dompdf_config.inc.php');

  $dompdf = new DOMPDF();

  $dompdf->load_html_file("http://ems-complete.com/pdf_email/patient-report.php");

    $dompdf->render(); 

    $dompdf->stream("file.pdf");*/

    $course = $_REQUEST['course'];

    $dir = dirname(__FILE__);

 require_once($dir.'/dompdf/dompdf_config.inc.php');
  $dompdf = new DOMPDF();

   $dompdf->load_html(file_get_contents("http://ems-complete.com/courseroster/courseroster.php?course=".$course));      


  $dompdf->render();
 // $dompdf->set_paper(2412, 3222);
  $dompdf->stream("courseroster.pdf");

 // exit(0);


?>

这是PHP HTML

<html>

Answer 1

在HTML生成脚本中，while循环外部有一个开头TR，看起来应该在循环内部（结束标记在循环内）。这将导致无效的文档结构，显然是dompdf无法解析的文档结构。

仅供参考，如果dompdf不解析文档，首先要做的是通过验证器运行它。

dompdf错误不能解决这个问题
