这是我的php代码:从Mysql中检索一个表并将其打印在页面上。
代码:
<?php
// Inialize session
session_start();
// Check, if username session is NOT set then this page will jump to login page
if (!isset($_SESSION['username'])) {
header('Location: index.php');
}
?>

基本上看起来有点像这样:
我需要的是此页面上的一个按钮,点击该按钮将同一个表格下载为PDF文件。
任何帮助都将不胜感激。
答案 0 :(得分:3)
将html轻松转换为pdf的唯一可行解决方案是使用domPdf库https://code.google.com/p/dompdf/。
您可以使用?pdf
get参数添加指向同一页面的链接,并在$_GET['pdf']
出现时通过dompdf输出您的php代码,而不是将其回显到浏览器。
查看wiki的用法: https://code.google.com/p/dompdf/wiki/Usage
我认为在您的情况下最简单的方法是添加:
if ( $_GET['pdf'] ) ob_start();
到页面顶部。 (启动输出缓冲区:请参阅http://php.net/manual/en/function.ob-start.php
和
if ( $_GET['pdf'] ) {
$html = ob_get_contents(); // this fills $html with all your output generated above.
//do the dompdf stuff here , using the $html variable.
}
到页面底部..
