一个字段插入数据库但另一个字段不插入

Question

我想通过html＆amp; mysqli连接在数据库中插入数据。我插入了名称和电子邮件，但是没有添加不幸的名字？

我的php连接代码是（显示12个没有行代码的错误）：

 <?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("localhost", "root", "", "studendata");

// Check connection
if($link === false){
    die("ERROR: Could not connect. " . mysqli_connect_error());
}

// Escape user inputs for security
$name = mysqli_real_escape_string($link, $_REQUEST['name']);
 $email = mysqli_real_escape_string($link, $_REQUEST['email']);

// attempt insert query execution
$sql = "INSERT INTO person (name,email) VALUES ('$name','$email')";
if(mysqli_query($link, $sql)){
    echo "Records added successfully.";
} else{
    echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}

// close connection
mysqli_close($link);
?>

任何人都可以说为什么我的名字不插入这里???
