带有 Bootstrap 的自定义电子邮件地址

Question

我有一张注册表，其中包含 "Username"、"Email"、"Password" 字段。我希望只能使用带有“@mychoice.it”的电子邮件（这只是一个示例）。

hitoeveryone@mychoice.it -> ok
erika@mychoice.it -> ok
anthony@gmail.it -> NO!!

有可能吗？我正在使用 bootstrap 和 PHP.

这是我的表格：

<form method="post" action="registration.php" >

        <div class="form-group" id="form-login" >
        <label for="exampleInputEmail1">Indirizzo Email</label>
        <input type="email" class="form-control" id="exampleInputEmail1" placeholder="nome.cognomeX@studio.unibo.it" name="Input_Email" required>
        </div>

        <div class="form-group"  id="form-login">
        <label for="exampleInputUsername1">Username</label> 
        <input type="name" class="form-control" id="exampleInputUsername1" placeholder="username" name="Input_Username" required>
        </div>

        <div class="form-group" id="form-login">
        <label for="exampleInputPassword1">Password</label>
        <input type="password" class="form-control" id="example_InputPassword1" name="Input_Password" placeholder="password" required>
        </div>

        <button type="submit" class="btn btn-default">Submit</button>
        <button type="reset" class="btn btn-default" value="Reset">Reset</button>

这是我的 PHP 注册脚本

<?php
session_start();
require 'connect.php';
if(isset($_POST['Input_Username'])) {
    $username = $conn->real_escape_string($_POST['Input_Username']);
}
if(isset($_POST['Input_Email'])) {
   $email = $conn->real_escape_string($_POST['Input_Email']);
}
if(isset($_POST['Input_Password'])) {
    $password = $conn->real_escape_string($_POST['Input_Password']);
}
$sql = "INSERT INTO utente (Email, Username, Password) VALUES ('$email', '$username', '$password')";
$result = $conn->query($sql);
$conn->close(); 
header("location:prova.php");  
?>

<?php
session_start();
require 'connect.php';
$allowed_domains = array("example.com","example2.com");
if(isset($_POST['Input_Username'])) {
    $username = $conn->real_escape_string($_POST['Input_Username']);
}
if(isset($_POST['Input_Email'])) {
   $email = $conn->real_escape_string($_POST['Input_Email']);
}
if(isset($_POST['Input_Password'])) {
$password = $conn->real_escape_string($_POST['Input_Password']);
}
$email = explode("@",$email);
if (in_array($email[1],$allowed_domains)) {
    $sql = "INSERT INTO utente (Email, Username, Password) VALUES ('$email', '$username', '$password')";
    $result = $conn->query($sql);
    $conn->close(); 
    header("location:prova.php");  
}else{
    DO SOMETHING ELSE HERE
}
?>
