我使用http://www.webformgenerator.eu/生成表单并将代码下载到我现有的项目中。
现在，在我按下提交按钮后，屏幕没有任何反应。我调试并看到提交正在工作，并且它在我编程时插入到数据库表中。
如果数据库插入成功，我想显示一条成功的消息。所以我只是做了一个回声“成功”。但它没有显示在任何地方。
有什么问题？
代码片段在这里。

*
* IMPORTANT - PLEASE READ:
* 1. YOU MUST UNCOMMENT THE CODE FOR IT TO WORK.
* - This means removing the '//' in front of each line.
* - If you do not know what php comments are see here: http://php.net/manual/en/language.basic-syntax.comments.php
*
* 2. YOU CAN ENTER ANY EMAIL ADDRESS IN THE $from VARIABLE.
* - This is the address that will show in the From column in your mail application.
* - If your form contains an email field, and you want to use that value as the $from variable, you can set $from = $this->fields['name of your email field'];
* - As stated in the description on codecanyon, this code does not mail attachments. Google 'php html email attachments' for information on how to do this

这似乎是一个标准脚本。会不会有错误？我的控制台说
