Question

我是Laravel的新手，我使用laravel 5.2并且我正在尝试使用DomPdf生成报告，但我收到错误：

class.pdf.php第3154行中的ErrorException

未定义的索引：

Answer 1

我遇到了同样的问题，我找到了一个对我没用的解决方案。

我传递给dompdf的HTML没有任何换行符，例如：

<html><body>content here<body></html>

在 body 标记后添加一个中断修复了问题。

<html><body>
content here
</body></html>

不知道发生了什么，但现在可行了。希望这也解决了你的问题。
