php 学生信息管理系统 修改怎么写

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=lookmsg=更新user=employeeempno=" . $empno . "idcard=" . $idcard);

}

else

header("location:stu_reg.php?action=lookmsg=增加user=employeeempno=" . $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=Adminaction=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=Adminaction=search");

else

header("location:stu_Query.php?user=Adminaction=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";

}

}

}

}

更新数据的页面及校验:

PHP怎么做学生数据管理系统

下载MYSQL 安装 创建数据库

下载PHP环境 WAMP并安装,下载编辑器例如sublime text,下载熟悉的php框架例如CI 将CI包解压至wamp的www文件夹下,使用sublime text 打开文件夹,配置CI框架内的数据库等信息,使用CI框架编写程序;

如何用php代码实现一个学生管理系统包括学生管理课程管理

这个不是一两句话能说清楚的,也不清楚你现在水平在什么位置。

不过我说一下,需要的技术和方法步骤。

首先,你要会html css 最好还会javascript

然后是php mysql

这五种最基本的技术。

然后:

1.先用html+css写好你程序用到的网站界面。

2.设计数据库,比如 学生表,课程表,班级表,教师表等等

3.用php写后台,如登陆后台,之后就是对数据库增删改查。

我要用PHP做一个学生信息管理系统类似教务在线 需要学习哪些知识?

登陆的话你要学习表单知识,php验证表单提交的数据,以及如何跟数据库进行匹配,注册的话也差不多,首先表单提交内容,php接收内容,最后一点不同的是注册是要写数据库的。所以三个知识点你最起码要懂。(表单 php接收数据 sql语言)这三个。;后台的话设计内容比较多,不过数据库方面的到是不外乎 1、查询 2、修改 3、删除 4、新增 这4种sql语言,最后一点就是你要懂html代码,因为这是学做网页的基本

学生管理系统php源码谁有

php学生管理系统源码,供大家参考,具体内容如下

功能:

1.添加/删除/修改

2.数据存储.

界面分布:

index.php

---主界面

add.php ---stu添加

action --- sql中add/del/update

(处理html表单--mysql的数据存储 && 页面跳转)

edit.php ---stu修改

menu.php

--首页
