dompdf: loading html files to render, doesn't work
提问by aneuryzm
dompdf is not able to generate a pdf from a page of my website. However, I've saved the page and uploaded it as simple static html file, and it worked!
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上传为简单的静态 html 文件，并且成功了！
So, I don't know if the issue is with the url, or something else.. this is the error I get:
所以，我不知道问题是出在 url 上，还是其他什么地方……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
警告：require_once(/home/o110334/public_html/dompdf/include/firephp.cls.php) [function.require-once]：无法打开流：/home/o110334/public_html/dompdf/dompdf_config 中没有这样的文件或目录.inc.php 第 194 行
致命错误：require_once() [function.require]：无法打开所需的 '/home/o110334/public_html/dompdf/include/firephp.cls.php' (include_path='.:/usr/lib/php:/usr/local /lib/php') 在 /home/o110334/public_html/dompdf/dompdf_config.inc.php 第 194 行
This is the code:
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 is trying all kinds of stuff/eval's when running local, you're better of trying:
DOMPDF 在本地运行时正在尝试各种东西/评估，你最好尝试：
1) the (granted, long way trip) of requesting the HTML by http:
1）通过http请求HTML的（当然，长途旅行）：
$dompdf->load_html_file('http://yourdomain.ext/'.$file);
2) Don't let DOMPDF evalbut use output buffering itself, and let DOMPDF load the resulting string of HTML.
2) 不要让 DOMPDFeval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();
?>
