我正在尝试创建一个网站，允许人们查看当前的＆＃34;积分＆＃34;他们有，以及他们收到这些积分的原因。 E.G：拿垃圾拿5分，洗碗拿10分。
虽然我已经设置了实际的积分系统和用户名和密码的数据库，但我不知道如何为管理员添加积分和提供原因的方法制定出前端方式。登录后在用户页面上。 任何帮助，将不胜感激 谢谢
答案 0 :(得分：1)
您需要一个包含用户下拉列表的表单（在html中），原因的文本框和带有提交按钮的点的文本框。单击时，它返回到服务器上的php文件，该文件使用$_GET或$_POST获取信息，然后使用mysqli_ php函数更新mysql数据库。然后，php文件可以显示成功/失败以及您可能希望显示给管理员的任何其他信息。
希望通过这些步骤，您可以使用谷歌并找到实际实现的相应代码，如果您遇到困难，请回到此处，显示您目前所拥有的内容，人们将很乐意为您提供帮助。
编辑：圣诞节我想写一些代码，所以这对你来说是一个艰难的开始。有一点你可以改进。您还需要创建一个报告，以便能够展示它的全部内容，但这可能有点太多了。祝你好运，享受。
