我正在尝试根据所需的产品数量生成pdf文件 .

$html2pdf->writeHTML($this->render($template, array(
        'offerte' => $offerte,
        'customer' => $customer
    ))->getContent());
    try {
        $html2pdf->output();
    } catch (Html2PdfException $e) {
    }

在html.twig文件中,我循环遍历$ offerte对象中的对象数量 . 但是当我的对象超过页面高度时,我得到502坏网关崩溃 . 因此,当我有一个表行时它工作得很好,但是当我有40行并且它比1 pdf页面大时,它会保持加载和崩溃 . 检查日志后,出现最大执行错误:

request.CRITICAL:未捕获的PHP异常Symfony \ Component \ Debug \ Exception \ FatalErrorException:“错误:超过30秒的最大执行时间”在/var/www/todo-symfony/vendor/tecnickcom/tcpdf/tcpdf.php第7776行{“exception”:“[object](Symfony \ Component \ Debug \ Exception \ FatalErrorException(code:0):错误:/ var / www / todo-symfony / vendor / tecnickcom / tcpdf /超过30秒的最大执行时间tcpdf.php:7776)“} []

当我在1页上有太多表行时,有没有办法启动新页面,或者出于另一个原因出现此错误?

我的html.twig模板文件正在加载:
