PHP 学生管理系统实现

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="http://www.mamicode.com/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‘])?$_GET[‘action‘]:‘‘;?><link href="http://www.mamicode.com/file/Style.Css" rel="stylesheet" type="text/css" /></head><body><?php if($user ==‘Admin‘&&$action==‘‘){ ?><table width="100%" border="0" cellpadding="3" cellspacing="1" class="css_table" bgcolor=‘#E1E1E1‘>  <tr class="css_menu">    <td colspan="3">      <table width="100%" border="0" cellpadding="4" cellspacing="0" class="css_main_table">        <tr>          <td class="css_main">注意</td>        </tr>      </table>    </td>  </tr>  <tr>    <td class="css_col11"><strong><font color=#50691B>一旦确定不可更改</font></strong></td>  </tr><form name = "check_stu" method="post" action="check_stu.php"><td><lable>请输入修改学生的学号:<input name = "c_ID" type="text" ><input name = "submit" type="submit" value="http://www.mamicode.com/确定"></lable></td></form></table><?php }else if ($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 = "http://www.mamicode.com/<?php echo $_GET[‘c_ID‘];?>">        <li><p>学生姓名:        <input name = "Name" type = "text" id = "Name"></p></li>        <li><p>专业:&nbsp;&nbsp;&nbsp;&nbsp;        <input name = "Major" type = "text" id = "Major"></p></li>        <li>            <p>性别:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;            <!-- <input name = "sex" type = "text" id = "sex"></p></li> -->            <input type="radio" name="sex" value="http://www.mamicode.com/男"/>男&nbsp;&nbsp;&nbsp;&nbsp;            <input type="radio" name="sex" value="http://www.mamicode.com/女"/>女&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</br>        </li>        <li><p>确定修改:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;        <input name = "submit" type = "submit" value = "http://www.mamicode.com/确定" >&nbsp;&nbsp;&nbsp;&nbsp;        <input class="Renew" value="http://www.mamicode.com/重写" type="reset" />&nbsp;&nbsp;</p></li>    </form>    </div><?php }else if ($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‘];    $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");
