PHP 學生管理系統實現

最近學校開了php課程，順便寫了個作業，分享一下吧。。。

都是很簡單的東西，新手用得著、、、

省略部分前端**、、、

首先是登入的校驗：

<?php 

session_start
(); 
$user = $_post['username'];
$pass = $_post['password'];
$_session['user'] = $user
; 
/*$enter = $_post['login_undo'];
管理員登入的校驗
*/$flag = false
; 
if($user == "admin"&& $pass == "root")
else
header('location:login.php?login=relog');
/*// 學生登入免校驗 
if($enter)
header('location:stupage.php');
*/

然後是註冊的校驗：

<?php

session_start
(); 
$s_id = $_post['s_id'];
$name = $_post['name'];
$idcard = $_post['idcard'];
$major = $_post['major'];
$*** = $_post['***'];
$_session['student'][$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]['***'] = $***
; 
header('location:tisi.html');
/*foreach($_session['student'] as $v)
else
header("location:stu_reg.php?action=look&msg=增加&user=employee&empno=" . $empno . "&idcard=" . $idcard);
}*/

畢業操作及加入歷史校驗：

<?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]['***']=$_session['student'][$s_id]['***'];
$_session['history'][$s_id]['major']=$_session['student'][$s_id]['major'];
unset($_session['student'][$s_id
]); 
header('location:graduate.php?user=admin&action=delete');

<?php

session_start
(); 
$search=$_post['search'];
unset($_session['search']);
/*echo '';
var_dump($_post['search']);
return ;
*/foreach ($_session['student'] as
$k1 => $value
) }
if(isset($i
)) 
header("location:stu_query.php?user=admin&action=search");
else
header("location:stu_query.php?user=admin&action=q_error");

遍歷學生資訊：

class="css_table" bgcolor='#e1e1e1'>
<?php
session_start
(); 
$user = isset($_session['user'])?$_session['user']:'';
if($user =='admin') else
if($k2=='idcard')else
if($k2=='***')else
if($k2=='name')else
if($k2 =='major'); 
echo "";
echo "";
if($k2=='s_id') $s_id=$k3; echo "$k3"; 
echo "";}}
}}?>

更新資料的頁面及校驗：

<?php if($user =='admin'&&$action=='')else
if ($action == 'change') else
if ($action == 'enchange') ?>

<?php

session_start
(); 
$s_id = $_post['c_id'];
$name = $_post['name'];
$major = $_post['major'];
$*** = $_post['***'];
$_session['student'][$s_id]['s_id'] = $s_id
; 
$_session['student'][$s_id]['name'] = $name
; 
$_session['student'][$s_id]['major'] = $major
; 
$_session['student'][$s_id]['***'] = $***
; 
header("location:stu_update.php?action=enchange");
