前言
一个简单的php➕mysql项目学生信息管理系统,用于广大学子完成期末作业的参考,该系统实现增、删、改、查等基本功能。
1、登录界面
<!doctype html> <html> <head> <meta charset="utf-8"> <title>无标题文档</title> <link rel="stylesheet" type="text/css" href="login.css" rel="external nofollow" > </head> <body> <div class="login"> <h2 class="BT">Login</h2> <div class="zm"> <form action="function.php?action=login" method="post"> 账号:<input type="number" name="user"> 密码:<input type="password" name="password"> <p>没有账号?点击<a href="newuser.php" rel="external nofollow" >注册</a></p> <div> <input type="submit" value="登录" class="dl"><input type="reset" value="重置" class="cz"> </div> </form> </div> </div> </body> </html>
当输入密码点击登录后会弹出“登录成功”或者“账号或密码有错误提示”
2、注册界面
<!doctype html> <html> <head> <meta charset="utf-8"> <title>无标题文档</title> <link rel="stylesheet" type="text/css" href="newuser.css" rel="external nofollow" > </head> <body> <div class="l"> <img src="微信图片_20220530195333333png.png" width="100px" height="100px"> <h3>学生成绩管理系统</h3> </div> <div style=" height: 130px; " > <a href="login.php" rel="external nofollow" class="ll" ></a></div> <div class="zc" style="padding-left: 30px;"> <h2 align="center" style="color:#D6CFCF;">DeleteStudent</h2> <form method="post" action=""> 账 号:<input type="number" class="id" name="id"> 密 码:<input type="password" class="password" name="password"> 确认密码:<input type="password" class="repassword" name="repassword"> <input type="submit" class="tj" value="注册" name="tj"> </form> </div> <?php include("connection.php"); if(isset($_POST["tj"])){ $id=$_POST["id"]; $password=$_POST["password"]; $repassword=$_POST["repassword"]; if($password==$repassword){ connection(); $sql="insert into user(userid,password)values('".$id."','".$password."')"; $result=mysql_query($sql); echo "<script>alert('注册成功!');location='login.php'</script>"; }else{ echo "<script>alert('密码不一致');location='newuser.php'</script>"; } } ?> </body> </html>
当输入密码点击注册后会弹出“注册成功”或者“密码不一致”或者账号密码不为空提示·
