PHP 学生管理系统实现

浏览数：54 / 时间：2015年06月09日

最近学校开了PHP课程，顺便写了个作业，分享一下吧。。。

都是很简单的东西，新手用得着、、、

省略部分前端代码、、、

首先是登录的校验：

<?php 
    session_start();
    
    $user = $_POST[‘userName‘];
    $pass = $_POST[‘passWord‘];
    $_SESSION[‘user‘] = $user;
    /*$Enter = $_POST[‘Login_undo‘];
    管理员登录的校验*/
    $flag = false;
    if($user == "Admin"&& $pass == "root")
    {
        setcookie("userName",$user,time()+1200);
        setcookie("userName",$pass,time()+1200);
        $flag = true;
        header(‘location:adminPage.php?user=‘ . $user);
    }
    else
        header(‘location:Login.php?login=relog‘);
    /*
    // 学生登录免校验    
    if($Enter)
    header(‘location:StuPage.php‘);
    */

然后是注册的校验：

<?php
    session_start();
    $s_ID = $_POST[‘s_ID‘];
    $Name = $_POST[‘Name‘];
    $IDcard = $_POST[‘IDcard‘];
    $Major = $_POST[‘Major‘];
    $sex = $_POST[‘sex‘];

    $_SESSION[‘student‘][$s_ID][‘s_ID‘] = $s_ID;
    $_SESSION[‘student‘][$s_ID][‘Name‘] = $Name;
    $_SESSION[‘student‘][$s_ID][‘IDcard‘] = $IDcard;
    $_SESSION[‘student‘][$s_ID][‘Major‘] = $Major;
    $_SESSION[‘student‘][$s_ID][‘sex‘] = $sex;
    header(‘location:tisi.html‘);
    /*foreach($_SESSION[‘student‘] as $v)
    {
        if($v == $s_ID)
        {
            header("location:stu_reg.php?action=look&msg=更新&user=employee&empno=" . $empno . "&idcard=" . $idcard);
        }
        else
            header("location:stu_reg.php?action=look&msg=增加&user=employee&empno=" . $empno . "&idcard=" . $idcard);
    }*/

毕业操作及加入历史校验：

<?php
    session_start();

    $s_ID=$_GET[‘s_ID‘];


    $_SESSION[‘history‘][$s_ID][‘s_ID‘]=$s_ID;
    $_SESSION[‘history‘][$s_ID][‘Name‘]=$_SESSION[‘student‘][$s_ID][‘Name‘];
    $_SESSION[‘history‘][$s_ID][‘IDcard‘]=$_SESSION[‘student‘][$s_ID][‘IDcard‘];
    $_SESSION[‘history‘][$s_ID][‘sex‘]=$_SESSION[‘student‘][$s_ID][‘sex‘];
    $_SESSION[‘history‘][$s_ID][‘Major‘]=$_SESSION[‘student‘][$s_ID][‘Major‘];

    unset($_SESSION[‘student‘][$s_ID]);

    header(‘location:graduate.php?user=Admin&action=delete‘);

任意关键词查询：

<?php
    session_start();
    
    $search=$_POST[‘search‘];
    unset($_SESSION[‘search‘]);

    /*echo ‘<pre>‘;
    var_dump($_POST[‘search‘]);
    return ;*/

    foreach ($_SESSION[‘student‘] as $k1 => $value) {
        # code...
        if($search==$_SESSION[‘student‘][$k1][‘s_ID‘]||$search==$_SESSION[‘student‘][$k1][‘IDcard‘]||$search==$_SESSION[‘student‘][$k1][‘Name‘]||$search==$_SESSION[‘student‘][$k1][‘sex‘]||$search==$_SESSION[‘student‘][$k1][‘Major‘]){
            $i = 1;
            $stu = $_SESSION[‘student‘][$k1][‘s_ID‘];
            $_SESSION[‘search‘][$stu] = $stu;
        }
    }
    if(isset($i))
        header("location:stu_Query.php?user=Admin&action=search");
    else
         header("location:stu_Query.php?user=Admin&action=q_error");

遍历学生信息：

<!DOCTYPE HTML>

<html>
<head>
<link href="file/Style.Css" rel="stylesheet" type="text/css" />
</head>
<body>
<table width="100%" border="0" cellpadding="1" cellspacing="1" class="css_table" bgcolor=‘#E1E1E1‘>
<?php
    session_start();
    $user = isset($_SESSION[‘user‘])?$_SESSION[‘user‘]:‘‘;
    if($user ==‘Admin‘){
        if(isset($_SESSION[‘student‘])){
            foreach($_SESSION[‘student‘] as $k1) { 
            echo "<tr>";
        
            foreach($k1 as $k2=>$k3) {
            echo "<td>" ;
            if($k2==‘s_ID‘) {echo "学号:" ;} else if($k2==‘IDcard‘){echo "身份证号:";}else if($k2==‘sex‘){echo "性别:";}else if($k2==‘Name‘){echo "姓名:";}else if($k2 ==‘Major‘){echo "专业:";}; 
            echo "</td>";
            echo "<td>";
            if($k2==‘s_ID‘) $s_ID=$k3;  echo "$k3"; 
            echo "</td>";
            }
        }
    }
}
?>
</table>
</body>
</html>

更新数据的页面及校验：

<!DOCTYPE HTML>
<!-- 使用HTML5规范，省略多余部分 -->
<html>
<head>
<?php 
    session_start();
    $user = isset($_SESSION[‘user‘])?$_SESSION[‘user‘]:‘‘;
    $action = isset($_GET[‘action‘])?$_GET[‘action‘]:‘‘;
?>

<link href="file/Style.Css" rel="stylesheet" type="text/css" />
</head>
<body>
<?php if($user ==‘Admin‘&&$action==‘‘){ ?>
<table width="100%" border="0" cellpadding="3" cellspacing="1" class="css_table" bgcolor=‘#E1E1E1‘>
  <tr class="css_menu">
    <td colspan="3">
      <table width="100%" border="0" cellpadding="4" cellspacing="0" class="css_main_table">
        <tr>
          <td class="css_main">注意</td>
        </tr>
      </table>
    </td>
  </tr>
  <tr>
    <td class="css_col11"><strong><font color=#50691B>一旦确定不可更改</font></strong></td>
  </tr>

<form name = "check_stu" method="post" action="check_stu.php">
<td><lable>请输入修改学生的学号:
<input name = "c_ID" type="text" >
<input name = "submit" type="submit" value="确定">
</lable></td>
</form>
</table>
<?php }else if ($action == ‘change‘) {?>
<form name="login_f" method="post" action="update_check.php">
    <div class = "login" align="center">

    <input name = "c_ID" type="hidden" value = "<?php echo $_GET[‘c_ID‘];?>">
        <li><p>学生姓名：

        <li><p>专业：&nbsp;&nbsp;&nbsp;&nbsp;
        <input name = "Major" type = "text" id = "Major"></p></li>
        <li>
            <p>性别：&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

            <input type="radio" name="sex" value="女"/>女&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</br>
        </li>
        <li><p>确定修改：&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
        <input name = "submit" type = "submit" value = "确定" >&nbsp;&nbsp;&nbsp;&nbsp;
        <input class="Renew" value="重写" type="reset" />&nbsp;&nbsp;</p></li>
    </form>
    </div>
<?php }else if ($action == ‘enchange‘) {
    # code...
    echo "<h1>已经改变</h1>";
}?>
</body>
</html>

<?php
    session_start();
    $s_ID = $_POST[‘c_ID‘];
    $Name = $_POST[‘Name‘];
    $Major = $_POST[‘Major‘];

    header("location:stu_Update.php?action=enchange");
