php - dompdf:加载要渲染的 html 文件，不起作用

Question

dompdf 无法从我网站的页面生成 pdf。但是，我保存了该页面并将其作为简单的静态 html 文件上传，并且成功了!

所以，我不知道是 url 问题还是其他问题。这是我得到的错误:

Warning: require_once(/home/o110334/public_html/dompdf/include/firephp.cls.php) [function.require-once]: failed to open stream: No such file or directory in /home/o110334/public_html/dompdf/dompdf_config.inc.php on line 194

Fatal error: require_once() [function.require]: Failed opening required '/home/o110334/public_html/dompdf/include/firephp.cls.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/o110334/public_html/dompdf/dompdf_config.inc.php on line 194

这是代码:

$file = "admin/store/orders/45/invoice/print"; // doesn't work
//$file = "invoice_sample2.html"; //it works (same web page, but stored in a html file)

$dompdf = new DOMPDF();
$dompdf->load_html_file($file);
$dompdf->render();
$dompdf->stream("sample.pdf");

DOMPDF 在本地运行时会尝试各种东西/eval，你最好尝试一下:

1) 通过 http: 请求 HTML 的(当然，长途旅行)

$dompdf->load_html_file('http://yourdomain.ext/'.$file);

2) 不要让 DOMPDF eval 而是使用输出缓冲本身，并让 DOMPDF 加载生成的 HTML 字符串。

<?php
    ob_start();
    //be sure this file exists, and works outside of web context etc.)
    require("admin/store/orders/45/invoice/print");
    $dompdf = new DOMPDF();
    $dompdf->load_html(ob_get_clean());
    $dompdf->render();
?>
