Question

创建了一个小型应用程序，可以在其中放置咖啡订单，并将订单及其订购日期保存到数据库中。

我有一个页面report.php，该页面根据来自管理页面adminPage.html的用户输入的日期约束来生成报告。

adminPage.html使用GET函数将日期约束传递给report.php，然后report.php使用具有这些约束的PHP生成报告。

我无法将报告页面转换为PDF。我尝试使用dompdf，但是，它不会将PHP报告加载到PDF中，而只会加载HTML代码。

用户单击按钮可在adminPage.html上运行报告的功能：

function runReport()
{
var jStartDate;
var jEndDate;
jStartDate = document.getElementById("reportStartDate").value;
jEndDate = document.getElementById("reportEndDate").value;

window.open("report.php?startDate="+jStartDate+"&endDate="+jEndDate+"");

}

window.open打开报告页面，并将约束加载到URL中。我知道那不漂亮，很抱歉：（

这是我要生成为PDF的报告页面。我希望屏幕底部有一个小按钮，上面写着“ generate PDF”（生成PDF），这样当用户按下它时，它就会生成PDF。

这是一个基本示例，说明您使用TCPDF时的样子

<?php
$pdf = new TCPDF(PDF_PAGE_ORIENTATION_L, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
//TCPDF_INIT_CODE_GOES_HERE 
// ...

$html = '<!DOCTYPE HTML>
<script 
src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js">

require "phpScripts/connect.php";

$startDate = $_GET['startDate'];
$endDate = $_GET['endDate'];

$sql = "SELECT * FROM orderlist WHERE NOT (dateOrdered < '$startDate' OR dateOrdered > '$endDate');";

$result = $conn->query($sql);

$html .= "<center>";
$html .= "<ul>";
if($result->num_rows >0)
{
    $i = 0;
    while($row = $result->fetch_assoc()) // this loads selected drinks via date

    {
        $html .=  "<li style=
        'margin-left: 0;
        list-style-type: none;

        height: 40px;

$pdf->writeHTML($html);
$pdf->Output('TITLE_OF_PDF_FILE.pdf', 'I'); // I flag means it will display the PDF in a browser

使用嵌入式PHP将HTML转换为PDF
