使用php編寫一個學生管理系統?很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
功能:
1.添加/刪除/修改
2.數據存儲.
界面分布:
index.php --->主界面
add.php --->stu添加
action ---> sql中add/del/update (處理html表單-->mysql的數據存儲 && 頁面跳轉)
edit.php --->stu修改
menu.php -->首頁
1. index.php
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>學生信息管理</title> <script> function doDel(id) { if(confirm('確認刪除?')) { window.location='action.php?action=del&id='+id; } } </script> </head> <body> <center> <?php include ("menu.php"); ?> <h4>瀏覽學生信息</h4> <table width="500" border="1"> <tr> <th>ID</th> <th>姓名</th> <th>性別</th> <th>年齡</th> <th>班級</th> <th>操作</th> </tr> <?php // 1. 鏈接數據庫 try{ $pdo = new PDO("uri:mysqlPdo.ini","root","1"); }catch (PDOException $e) { die('connection failed'.$e->getMessage()); } //2.執行sql $sql_select = "select * from stu"; //3.data 解析 foreach ( $pdo->query($sql_select) as $row) { echo "<tr>"; echo "<th>{$row['id']} </th>"; echo "<th>{$row['name']}</th>"; echo "<th>{$row['sex']} </th>"; echo "<th>{$row['age']} </th>"; echo "<th>{$row['classid']}</th>"; echo "<td> <a href='edit.php?id={$row['id']}'>修改</a> <a href='javascript:void(0);' onclick='doDel({$row['id']})'>刪除</a> </td>"; echo "</tr>"; } ?> </table> </center> </body> </html>
2. add.php
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>學生管理系統</title> </head> <body> <center> <?php include ('menu.php'); ?> <h4>增加學生信息</h4> <form action="action.php?action=add" method="post"> <table> <tr> <td>姓名</td> <td><input type="text" name="name"></td> </tr> <tr> <td>年齡</td> <td><input type="text" name="age"></td> </tr> <tr> <td>性別</td> <td><input type="radio" name="sex" value="男">男</td> <td><input type="radio" name="sex" value="女">女</td> </tr> <tr> <td>班級</td> <td><input type="text" name="classid"></td> </tr> <tr> <!-- <td> </td>--> <td><a href="index.php">返回</td> <td><input type="submit" value="添加"></td> <td><input type="reset" value="重置"></td> </tr> </table> </form> </center> </body> </html>
3. action.php
