外部 PHP 文件到 dompdf答案

【问题标题】：External PHP file to dompdf外部 PHP 文件到 dompdf
【发布时间】：2018-04-17 09:25:48
【问题描述】：

我有以下 PHP 文件 course.php，我希望 dompdf 呈现该文件。但是，当我尝试加载外部文件时，它会告诉我标题已经加载。

我已经尝试了一些在线教程，但是当我添加内联 php 时，pdf 无法正确呈现。

是否可以添加外部 php 文件？

<?php

include config.php
$course_id= JRequest::getInt('cid');

$dbname = "i2894069_jos2";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT en . * , e.full_name, e.level , c.base_level, s.station
FROM enrolled_students AS en
JOIN employees AS e ON en.student = e.user_id
JOIN stations AS s ON e.station = s.id
JOIN courses_instructed AS ci ON en.pid = ci.ci_id
JOIN courses as c on ci.ci_course = c.id
WHERE en.pid =$course_id
ORDER BY  e.last_name";
$result = $conn->query($sql);
?>

【问题讨论】：

您得到的究竟是什么错误信息？顶部的行应该是include 'config.php';；这可能会也可能不会解决您的问题。

标签： php html dompdf

【解决方案1】：

如果我对您的理解正确...您正在寻找的是这样的：

<?php

ob_start();
require 'yourtemplate.php'; // the one you posted in your question
$html = ob_get_clean();

现在您的 HTML 位于一个变量中，如果需要，您可以使用 DOMPDF 呈现它。
