Your html form using您的 html 表单使用

Firstname: <input type="text" name="fname" /><br><br>

Lastname: <input type="text" name="lname" /><br><br>

but your PHP get from但是你的 PHP 从

$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];

it should used the same name.它应该使用相同的名称。 Like喜欢

$first_name = $_POST['fname'];
$last_name = $_POST['lname'];
