我准备了一个表格,用于生成PDF,然后下载提交数据的文件。在我的代码中,我需要通过mPdf库来完成它,它生成如下文件:
$mpdf = new \Mpdf\Mpdf();
// Write some HTML code:
$html = "Here comes what must be displayed in the PDF file"
$mpdf->WriteHTML($html);
// Output a PDF file directly to the browser
$mpdf->Output('ticket.pdf', \Mpdf\Output\Destination::DOWNLOAD);
在我的$ html中,我需要创建一个表格,该表格提供了通过$ _POST获得的数据的组合,例如但是,当我如下所示,我有很多错误。
$html = "<table>ID: $_POST['someVariable']</table>";
下面你可以找到我用来生成文件的整个代码,然后下载它。你能帮帮我吗?我真的很感谢你对新秀的帮助:)。
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$from = filter_input(INPUT_POST, 'from');
$to = filter_input(INPUT_POST, 'to');
$start = filter_input(INPUT_POST, 'start');
$price = filter_input(INPUT_POST, 'price');
$length = filter_input(INPUT_POST, 'length');
$timezoneFrom = getTimezone($from, $airports);
$timezoneTo = getTimezone($to, $airports);
validate($from, $to, $start, $price, $length);
echo "from " . $timezoneFrom . "<br>";
echo "to " . $timezoneTo . "<br>";
$dateFrom = new DateTime($start, new DateTimeZone($timezoneFrom));
echo $dateFrom->format('Y-m-d H:i:s e') . "<br>";
$dateTo = clone $dateFrom;
echo "clone of date :";
echo $dateTo->format('Y-m-d H:i:s e') . "<br>";
$dateTo->setTimezone(new DateTimeZone($timezoneTo));
echo "after timezone change:";
echo $dateTo->format('Y-m-d H:i:s e') . "<br>";
$dateTo->modify($length . ' hours');
echo $dateTo->format('Y-m-d H:i:s') . "<br>";
echo "Data OK";
}
require_once __DIR__ . '/vendor/autoload.php';
$mpdf = new \Mpdf\Mpdf();
// Write some HTML code:
$html = "

如果你有的话,请不要犹豫,向我提出建议和问题。 问候。
答案 0 :(得分:0)
你应该从不直接将用户输入传递给HTML(甚至不是HTML到PDF输入,以保持最佳实践并支持代码可重用性),因为您的代码将是XSS易受攻击的。您应该使用htmlspecialchars
函数正确处理输入。
$someVariableOutput = htmlspecialchars($_POST['someVariable']);
关于你原来的问题:
您需要使用.
运算符将字符串与变量连接起来:
$html = "<table>ID: " . $someVariableOutput . "</table>";
或者您可以用双引号字符串显示变量:
// the {} are just for a good measure here
// they would be useful when printing eg. an array key.
$html = "<table>ID: {$someVariableOutput}</table>";
