Question

这是我的打印代码：

<?php

if ($_GET['id'] == "print")
{

include ("../config.php");
include ("../classes.php");

$result = $Adder->getPrintData($_POST['value']);

if ($result->num_rows > 0)
{
    $data = "";
    $html_data = "";
    while ($row = $result->fetch_assoc())
        {
        switch ($row['birth_type_id'])
            {
        case 1:
            $hospital_id = $row['hospital_id'];
            $home_detail = "None";
            $other_detail = "None";
            $birth_formatted_type = "Birth at : " . $Viewer->getHospitalName($row['hospital_id']);
            break;

        case 2:
            $hospital_id = "None";
            $home_detail = $row['home_detail'];
            $other_detail = "None";
            $birth_formatted_type = "|| Birth at Home || <br />Home Details Are : " . $row['home_detail'];
            break;

        case 3:
            $hospital_id = "None";
            $home_detail = "None";
            $other_detail = $row['other_detail'];
            $birth_formatted_type = "|| Birth at Other Location || <br />Details Are : " . $row['other_detail'];
            break;

        default:
            $hospital_id = "None";
            $home_detail = "None";
            $other_detail = "None";
            break;
            }

   $data.= "<div style='width: 100%;'>

    require "../dompdf/dompdf_config.inc.php";

    $dompdf = new DOMPDF();
    $dompdf->set_paper('A4', 'landscape');
    $dompdf->load_html($html_data);
    $dompdf->render();
    $dompdf->stream("PD444607_Date_" . $_POST['value'] . ".pdf");
    }
}

使用不同的文件大小生成pdf，但是当我打开pdf时，它会显示错误消息，如

无法打开pdf

当我正在进行echo时，如下所示

echo $html_data;

每个数据都是可见的，它没有显示任何错误。我已经调试了每个级别的代码。只有在生成pdf时，它才会打开。

这是变量$result;

中的数据

public function getPrintData($value)
{
    $query = "SELECT * FROM certificate_details WHERE created LIKE '%$value%' ";
    $connection = $this->establish_connection();
    $result = $connection->query($query);
    $connection->close();
    return $result;
}

Answer 1

我找到了解决方案。问题是我在执行PHP脚本之前设置了标题和图标来生成pdf。所以我认为这是作为标题捕捉。所以我删除了那个＆amp;问题解决了。

pdf在生成DOMPDF后无法打开
