Question

我有一个注册表，有“用户名”，“电子邮件”，“密码”字段。我想只能使用带有“@ mychoice.it”的电子邮件（这只是一个例子）。

 var quiz = [{
    "question": ["When was the first apple computer made?"],
    "choices": ["1904","1976","1978","2004"],
    "correct": ["1976"]
}, {
    "question": "Who is the founder of Microsoft?",
    "choices": ["Bill Gates", "Steve Jobs", "Steve Wozniak" , "Martin Shaba"],
    "correct": "Bill Gates"
}, {
    "question": "What was your first dream?",
    "choices": ["8 bits", "64 bits", "1024 bits"],
    "correct": "8 bits"
}, {
   "question": "The C programming language was developed by?",
   "choices": ["Brendan Eich", "Dennis Ritchie", "Guido van Rossum"],
   "correct": "Dennis Ritchie"
}, {
  "question": "What does CC mean in emails?",
  "choices": ["Carbon Copy", "Creative Commons", "other"],
  "correct": "Carbon Copy"
}, {
    "question": "What is the full for of IP",
    "choices": ["Internet provider", "Intenet Port", "Other","Internet Protocol"],
    "correct": "Other"
}];
 quiz.forEach(question=>question.choices.scramble());

var score=0;

function ask(index){
      index= (index||0) % quiz.length; //let index be valid
      var question=quiz[index];
      //ask the question
      var answer=prompt(question.question+" ["+question.choices.join("] [")+"]");
      //exit on false
      if(!answer) return alert("Goodbye! Your score is "+score);
      //check if user was right
      if(answer===question.correct){
        alert("Yes. Youre right!");
        score++;
     }else{
       alert("Nope it was "+question.correct);
    }
   //procceed to the next question
   ask(index+1);//next question
}

//lets start
ask(0);

有可能吗？我正在使用bootstrap和PHP。

这是我的表格：

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

这是我的PHP脚本进行注册

<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>

<?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
}
?>
