在服务器上将带有CSS的动态PHP页面的内容另存为pdf

标签： php css pdf-generation dompdf

我有一个PHP页面，该页面从数据库中检索页面本身中显示的各种数据。我想生成包含内容的PDF文件，并将该文件保存在服务器中以备后用。我的PHP页面在浏览器中呈现完美。
我尝试使用header('Content-disposition: attachment; filename=filename.pdf');，但收到错误Failed to load PDF document.
我也尝试过dompdf，但最终得到了空白的pdf文档。
由于该文件包含一些敏感数据，因此我不冒险将内容发送到第三方服务器。请帮帮我。

  

我的文件主要包含PHP和CSS。

<?php
include('php-include/connect.php');

if(isset($_GET['purpose']) && isset($_GET['membership'])) {
    $purpose = $_GET['purpose'];
    $membership = $_GET['membership'];
    if ($purpose == 'Volunteer Membership') {
        $member_type = 'temporary';
        $query = mysqli_query($con,"select * from temp_members where `membership`='$membership'");
        if (mysqli_num_rows($query) > 0) {
            while ($row = mysqli_fetch_array($query)) {
                $name = $row['name'];
                $email = $row['email'];
                $address = $row['address'];
                $city = $row['place'];
                $state = $row['state'];
                $country = $row['country'];
                $pin = $row['pin'];
                $bloodgroup = $row['bloodgroup'];
                $dob = $row['dob'];
            }
        }
    } 
}

$count = substr($membership,-10);
$myDateTime = DateTime::createFromFormat('Y-m-d', $dob);
$dob = $myDateTime->format('d/m/Y');
$today = date('d/m/Y');
switch ($member_type) {
    case 'temporary':
        $validity = strtotime("+6 months");
        $validity = date('d/m/Y', $validity);
        break;
    case 'default':
        $validity = 'Lifetime';
}
?>

我在这里已经提到了与上述两种方法相对应的两种代码。请查看代码，并指导我获得所需的输出。
谢谢。

仅添加说明您返回的内容为PDF类型的标头是不够的，因为您发送的内容不是该格式。 我可以告诉您，我有使用fpdf（http://www.fpdf.org/）在PHP中创建PDF文档的经验，并且效果很好。 您可以使用FPDF库创建文档，然后返回文件内容，而不是当前返回的HTML。
