php到mySQL提交按钮工作，后端不要

Question

所以我的问题是页面的美观效果，直到你点击提交按钮的位置（它的工作原理是因为有一个加载图像设置为在通过jquery.contact单击按钮后出现。 JS）。但是，它会在加载图像处停留，并且不会返回提示已成功提交的消息，也不会返回到我的数据库中，也不会发送确认电子邮件（忽略）。

我想知道出了什么问题以及我如何解决它，如果可能的话，我可以快速完成这项任务，以便快速完成这项工作？

这是脚本：

的index.php

<div id="contact">
        <h1>Contact us</h1>
          <form id="ContactForm" action="">
            <p>
                <label>Name</label>
                <input id="name" name="name" class="inplaceError" maxlength="120" type="text" autocomplete="off"/>
                <span class="error" style="display:none;"></span>
            </p>
            <p>
                <label>Email</label>

Answer 1

此代码似乎源自http://tympanus.net/codrops/2010/03/12/php-mysql-contact-form-with-jquery/的“PHP / MySQL联系表格与jQuery”演示，这对我来说非常适合“开箱即用”。

由于你没有提到配置，我猜你要么没有编辑config.php以反映你自己的数据库：

define('DB_SERVER'          , 'localhost');
define('DB_USER'            , 'root');
define('DB_PASS'            , '');
define('DB_NAME'            , 'ContactForm');

或者，您可能忘了将SEND_EMAIL从false更改为true

define('SEND_EMAIL', true);

Answer 2

很难......我自己也有过。 问题不在于编程方面;是关于PHP environement的版本。

该代码在PHP 5.4.12和Apache 2.4.4上完美运行。并且在PHP 5.3.27和Apahe 2.2.25上没有将'result'识别为属性，因为没有价值。 完全相同的代码！奇怪但真实......

所以...我不认为，在语言方面，任何人都可以帮助你/我们。 干杯！

PS - 一旦你提交了联系表格，就会出现IE浏览器返回的葡萄牙语错误（在更高版本的environement中使用的错误！），
