我的模板页面中有一些自定义表单。我正在使用表单“action”链接到formtoemail。php文件。如果我离开formtoemail，一切都会好起来的。php原样，但我想调用我的主题元素来动态设置页面样式。
我尝试了以下操作，但不幸的是出现了一个错误“调用未定义的函数get\\u header（）”
如果我从页面复制/粘贴html，一切都很好，但我真的不想每次都更新html。我确信有一种方法可以做到这一点，但我不是超级PHP高手。有人能帮忙吗？
<?php
$my_email = "[email protected]";
/*
Enter the continue link to offer the user after the form is sent. If you do not change this, your visitor will be given a continue link to your homepage.
If you do change it, remove the "/" symbol below and replace with the name of the page to link to, eg: "mypage.htm" or "http://www.elsewhere.com/page.htm"
*/
$continue = "/";
/*
Step 3:
Save this file (FormToEmail.php) and upload it together with your webpage containing the form to your webspace. IMPORTANT - The file name is case sensitive! You must save it exactly as it is named above! Do not put this script in your cgi-bin directory (folder) it may not work from there.
THAT\'S IT, FINISHED!
You do not need to make any changes below this line.
