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");
