$uri1 = substr($data1,strpos($data1,",")+1);
$uri2 = substr($data2,strpos($data2,",")+1);
$path =$_SERVER["DOCUMENT_ROOT"].'/divya/custom_product/sites/default/files/cart';

<?php
require_once("dompdf_config.inc.php");
require_once("sites/all/modules/print/lib/dompdf/dompdf_config.inc.php");
$tbl = '<html style="margin:20px 20px 0px; padding:0;">
<body style="margin:0; padding:0;">
<table style="margin:0px 0px 5px 3px;">

$dompdf = new DOMPDF;
$dompdf->load_html($tbl);
$dompdf->render();
$pdfoutput = $dompdf->output();
// Checks whether there is an output folder inside sites/default/files
if (!is_dir('public://output')) {
mkdir("public://output", 0777);
// Creates a folder and changes its permissions}
$filename = 'sites/default/files/output/' . 'sample.pdf'
$fp = fopen($filename, "w+");
fwrite($fp, $pdfoutput);
// Writes the pdf output to a file
fclose($fp);

After going through the DOMPDF wiki here , I realized that the default mode of operation is to stream the file back to the client, not necessarily save it to a file. 通过DOMPDF维基会后在这里 ，我意识到，默认操作模式是流的文件返回给客户端，不必将其保存到一个文件中。 So I started digging around some more. 所以我开始研究更多。
This question was posted before; 这个问题以前发布过； they use similar code to you, but use the much simpler file_put_contents() to write the file. 他们使用与您相似的代码，但使用简单得多的file_put_contents（）来写入文件。 It's still worth trying to write a simple text file first to that location just to rule out any file system issues. 仍然值得尝试先将一个简单的文本文件写入该位置，以排除任何文件系统问题。

在创建DOMPDF类时，您缺少了寄生：
$dompdf = new DOMPDF();

Have you enabled error logging? 您是否启用了错误日志记录？ Error logs, many a times, tell you exactly what is wrong 错误日志很多次会告诉您确切的错误
