PHP 学生管理系统实现

浏览数：60 / 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">
	<lable>可以修改的项目：</lable>
	<input name = "c_ID" type="hidden" value = "<?php echo $_GET['c_ID'];?>">
		<li><p>学生姓名：
		<input name = "Name" type = "text" id = "Name"></p></li>
		<li><p>专业：    
		<input name = "Major" type = "text" id = "Major"></p></li>
		<li>
			<p>性别：          
			<!-- <input name = "sex" type = "text" id = "sex"></p></li> -->
			<input type="radio" name="sex" value="男"/>男    
	    	<input type="radio" name="sex" value="女"/>女     </br>
	    </li>
		<li><p>确定修改：      
		<input name = "submit" type = "submit" value = "确定" >    
		<input class="Renew" value="重写" type="reset" />  </p></li>
	</form>
	</div>
<?php }else if ($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'];
	$sex = $_POST['sex'];

	$_SESSION['student'][$s_ID]['s_ID'] = $s_ID;
	$_SESSION['student'][$s_ID]['Name'] = $Name;
	$_SESSION['student'][$s_ID]['Major'] = $Major;
	$_SESSION['student'][$s_ID]['sex'] = $sex;

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

一些前端设计：

<!DOCTYPE HTML>
<!-- 使用HTML5规范 -->
<html>
<head>
<title>main</title>
<link href="file/Style.Css" rel="stylesheet" type="text/css" />
</head>
<body>
  <?php  session_start(); ?>
  <?php 
     $user = isset($_SESSION['user'])?$_SESSION['user']:"";
  ?>
  <?php
    if($user == "")
    {
      // header("location:Login.php");
      die("<script>
            if(typeof(parent) != 'undefined'){
                parent.window.location = 'Login.php';
            }else{
                window.location.href = 'Login.php';
            }
          </script>");
    }
  ?> 
  <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>欢迎<?php echo "$user";?></td>
          </tr>
        </table>
      </td>
    </tr>
    <tr>
       <td class="css_col11"><strong><font color = "#0000FF">登录cookie有效时间为1200秒</a></strong></td>
    </tr>
  </table>
  <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">联系方式</td>
          </tr>
        </table>
      </td>
    </tr>
    <tr>
      <td class="css_col11"><strong><font color=#50691B>Blog:http://blog.csdn.net/p641290710</font></strong></td>
      <td class="css_col11"><strong><font color=#50691B>Email:[email protected]</font></strong></td>
    </tr>
  </table>
  <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>Github</td>
          </tr>
        </table>
      </td>
    </tr>
    <tr>
       <td class="css_col11"><strong><a href="https://github.com/Joypeng" target="_blank"><font color=#50691B>点击进入本人Github</font></a></strong></td>
