php 简单操纵数据库个人资料管理系统

按下列要求完成各个页面：（提示：在做此题前需先建立一数据库，包含一张表，此表至少包含 5 个字段（姓名，性别，兴趣爱好，家庭住址，备注）），

首先展示一下各个界面实现后的效果

页面大概如上述所示。接下来看一下各个功能的代码实现(代码折叠框上的名称即为此文件的名称)：

1.创建mysql表

biao.php

<?php
$servername = "localhost";
$username = "root";//数据库名称
$password = "root";//数据库密码
$dbname = "syFour";//数据库的名字

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 使用 sql 创建数据表userinfo为表名
$sql = "CREATE TABLE userinfo (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
name VARCHAR(30) NOT NULL,
male VARCHAR(10) NOT NULL,
hobby VARCHAR(255),
address varchar(255),
beizhu varchar (255)
)";

if ($conn->query($sql) === TRUE) {
    echo "Table MyGuests created successfully";
} else {
    echo "创建数据表错误: " . $conn->error;
}

$conn->close();

2.添加界面显示：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        p{
            font-weight: bold;
        }
    </style>
</head>


<body>

<form action="insert.php" method="post" >
    <table border="1" align="center" width="500">
        <thead >
        <tr>
            <td colspan="2" align="center" bgcolor="#808080" > <p>添加个人资料</p></td>
        </tr>

        </thead>
        <tbody>
            <tr>
                <td>真实姓名</td>
                <td><input type="text" name="name" id="name"></td>
            </tr>
            <tr>
                <td>性别</td>
                <td>
                    <input type="radio"   name="sex" value="男"/>男
                    <input type="radio"  name="sex" value="女" />女
                </td>
            </tr>
            <tr>
                <td>兴趣爱好</td>
                <td><input type="text" name="hobby" id="hobby"/></td>
            </tr>
            <tr>
                <td>家庭住址</td>
                <td>
                    <select name="address">
                        <option>中国</option>
                        <option>美国</option>
                        <option>日本</option>
                        <option>韩国</option>

                    </select>
                </td>
            </tr>
            <tr>
                <td>备注</td>
                <td>
                    <textarea name="bz" cols="50" rows="5"></textarea>
                </td>
            </tr>
            <tr>

                <td colspan="2" align="center"><input type="submit" value="提交" name="sub"/>
                    <input type="reset" value="重置" name="reset">
                </td>

            </tr>
        </tbody>
    </table>
</form>
</body>
</html>

insert.html

3.添加功能实现：

<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "syFour";
$name = $_POST['name'];
$sex = $_POST['sex'];
$hobby = $_POST['hobby'];
$address = $_POST['address'];
if($_POST['bz']==null){
    $bz="这家伙很懒，什么也没有留下";
}else{
    $bz = $_POST['bz'];
}



// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

$sql = "INSERT INTO userinfo (name,male,hobby,address,beizhu)
VALUES ('".$name."','".$sex."','".$hobby."','".$address."','".$bz."')";

if ($conn->query($sql) === TRUE) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
header("Location:select.php");

$conn->close();

insert.php

4.查询全部功能实现：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        p{
            font-weight: bold;
        }
        .wrapper{
            width: 1000px;
            margin: 20px auto;
        }
        h2{
            text-align: center;
        }
    </style>
</head>
<body>
    <div class="wrapper">
        <h2>学生个人信息表</h2>
        <div class="add">
                <a href="insert.html">添加个人资料</a>
        </div>
        <table width="960" border="1">
            <tr>
                <th>ID</th>
                <th>姓名</th>
                <th>性别</th>
                <th>爱好</th>
                <th>地址</th>
                <th>备注</th>
                <th>操作</th>
            </tr>

            <?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "syFour";

// 创建连接
$conn = mysqli_connect($servername, $username, $password, $dbname);


// Check connection
if (!$conn) {
    die("连接失败: " . mysqli_connect_error());
}

$sql = "SELECT * FROM userinfo order by id asc";
//结果集
$result = mysqli_query($conn, $sql);
//解析结果集
            $userNum = mysqli_num_rows($result);
            for($i=0;$i<$userNum;$i++){
                $row = mysqli_fetch_assoc($result);
                echo"<tr>";
                echo"<td>{$row['id']}</td>";
                echo"<td>{$row['name']}</td>";
                echo"<td>{$row['male']}</td>";
                echo"<td>{$row['hobby']}</td>";
                echo"<td>{$row['address']}</td>";
                echo"<td>{$row['beizhu']}</td>";
                echo"<td>
                            <a href='javascript:del({$row['id']})'>删除</a>
                            <a href='update.php?id={$row['id']}'>修改</a>
                     </td>"  ;
                echo"</tr>";
            }
            //5.释放结果集
            mysqli_free_result($result);
            mysqli_close($conn);

?>
        </table>
    </div>
<script type="text/javascript">
    function del(id){
        if(confirm("确定删除此人信息？")){
            window.location= "delete.php?id="+id;
        }
    }
</script>
</body>
</html>

select.php

5.修改页面实现：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>

</head>


<body>
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "syFour";
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
$id = $_GET['id'];
$sql = mysqli_query($conn,"select * from userinfo where id = $id ");
$sql_arr = mysqli_fetch_assoc($sql);
?>
<form action="update2.php" method="post">
    <label>ID: </label><input type="text" name="id" readonly value="<?php echo $sql_arr['id']?>"><br/>
    <label>姓名: </label><input type="text" name="name" value="<?php echo $sql_arr['name']?>"><br/>
    <label>性别：</label>
        <input type="radio"   name="male" value="男" checked/>男
        <input type="radio"  name="male" value="女" />女
   <br/>
    <label>兴趣爱好：</label><input type="text" name="hobby" value="<?php echo $sql_arr['hobby']?>"><br/>
    <label>家庭住址：</label>
    <select name="address" >
        <option>中国</option>
        <option>美国</option>
        <option>日本</option>
        <option>韩国</option>
    </select><br/>
    <label>备注：</label><input type="text" name="beizhu" value="<?php echo $sql_arr['beizhu']?>"><br/>

    <input type="submit" value="提交">
</form>

</body>
</html>
<?php

update.php

6.修改功能实现：

<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "syFour";
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
//获取修改的用户信息
$id = $_POST['id'];
$name = $_POST['name'];
$male = $_POST['male'];
$hobby = $_POST['hobby'];
$address = $_POST['address'];
$beizhu = $_POST['beizhu'];
//更新数据
mysqli_query($conn,"update userinfo set name='$name',male='$male',
hobby='$hobby',address='$address',beizhu='$beizhu' where id='$id'")or die('修改出现错误'.mysqli_error());
header("Location:select.php");

update2.php

7.删除功能实现：

<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "syFour";
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
$id = $_GET['id'];
mysqli_query($conn,"DELETE FROM userinfo WHERE id='$id'") or die("删除数据出错".mysqli_error());

header("Location:select.php");

delete.php

到此基本功能基本实现，此实验主要练习了一下php对mysql数据库的具体操作，具体可以参考一下菜鸟教程相关案例。
