Dom PDF问题生成输出

如何解决Dom PDF问题生成输出

我对dom pdf有一个小问题。我正在用它来教如何从样本商店生成pdf。样品商店在结帐时会生成一张收据，其中包含从商店中选择的所有产品。如果我选择一些项目并生成收据，则pdf输出看起来不错，它显示了我选择的产品并显示了总额。但是，如果我在生成收据时选择了很多产品（足以填满2页），则pdf输出仅显示第一页，而第二页的总数未显示？

此外，pdf会自动上传到服务器上的文件夹。我有一个链接，可以查看按日期顺序列出的收据，每个收据都已链接。我可以通过单击它们的各个链接来查看这些收据，但是如果我这样做，它们会自动下载到我的设备中。可以更改此设置，使其在浏览器中查看而不自动下载。

这是我dom pdf中代码的一部分：

$options = new Dompdf\Options();

    $options->set('isRemoteEnabled',true);

    $dompdf = new Dompdf\Dompdf($options);

    $dompdf->loadHtml($html);

    $dompdf->render();

    $output = $dompdf->output();

    $info = file_put_contents("../../files/" . $filepath . $filename,$output);

当我查看收据时，链接是通过handler.php进行的，我可以将其更改为在浏览器中查看，而不是自动下载吗？

handler.php
