增加
首先，建立一个主页面（crud.php）
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <?php $db = new Mysqli("localhost","root","root","student"); !empty(mysqli_connect_error())?die("连接错"):""; $sql = "select * from student"; $data = $db->query($sql)->fetch_all(); //var_dump($data); <table border="1"> <tr> <td>ID</td> <td>姓名</td> <td>性别</td> <td>出生年月</td> <td>班级</td> <td>删除</td> <td>修改</td> </tr> <?php foreach ($data as $i){ if ($i[2] == 1){ $i[2] = "男"; } else if ($i[2] == 0){ $i[2] = "女"; } else{ $i[2] = "保密"; } echo "<tr><td>{$i[0]}</td><td>{$i[1]}</td><td>{$i[2]}</td><td>{$i[3]}</td><td>{$i[4]}</td><td><a href='dele.php?id={$i[0]}'> 删除 </a></td><td><a href='edit.php'> 修改 </a></td><tr>"; } ?> <!-- 2--> </table> <a href="add.php">新增用户</a> </body> </html>
一、增加
1、建立add.php ，插入表单
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post" action="addpost.php"> <input type="text" name="Sno" placeholder="id"> <input type="text" name="Sname" placeholder="姓名"> <input type="radio" name="Ssex" value="1" id="man"><label for="man">男</label> <input type="radio" name="Ssex" value="0" id="woman"><label for="woman">女</label> <input type="text" name="Sbirthday" placeholder="出生年月"> <input type="text" name="Class" placeholder="班级"> <input type="submit" value="提交"> </form> </body> </html>
2、在addpost.php里做数据库增加处理
<?php $id = $_POST['Sno']; $name = $_POST['Sname']; $sex = $_POST['Ssex']; $birthday = $_POST['Sbirthday']; $class = $_POST['Class']; $db = new Mysqli("localhost","root","root","student"); $sql = "insert into student.student VALUES ('{$id}','{$name}','{$sex}','{$birthday}','{$class}',0)"; //var_dump($db->query($sql)); if ($db->query($sql)){ header("location:crud.php"); }else{ header("location:add.php"); }
测试一下：
1、主页
2、点击 增加用户 增加内容
3、点击 提交 ，看一下
