如何检查用户并传递然后重定向

时间：2017-03-29 19:00:03

标签： javascript php jquery mysql ajax

这是我用于项目的模板：

http://bootsnipp.com/snippets/featured/custom-login-registration-amp-forgot-password

我想使用我的phpMyAdmin登录模板来检查用户名和密码。

  1. 用户输入他们的帐户，然后点击提交按钮

  2. 点击提交按钮后，图标将从箭头变为动画圈（此时我希望用数据库phpMyAdmin检查用户和密码）

  3. 如果他们的帐户和密码与数据库匹配，则会显示＆＃34;登录成功＆＃34;消息，如果他们不匹配，用户名或密码错误＆＃34;消息将显示。

  4. 如果用户名和密码匹配，请等待3秒钟，然后重定向到另一个页面。

    5. 我不知道如何将我的phpMyAdmin与此登录表单合并。因此，如果您知道如何操作，请告诉或建议我如何完成此项目。

    这是我的代码：
