ページを更新せずにお問い合わせフォームを使用しています。しかし、フィールドが空であっても送信ボタンをクリックした後、必要な属性が機能しません。私を助けてください

$name = $_POST['name'];

$message = $_POST['message'];

    $to = 'babloopuneeth@gmail.com';
    $subject = 'the subject';
    $message = 'FROM: '.$name.' Email: '.$email.'Message: '.$message;
    $headers = 'From: youremail@domain.com' . "\r\n";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { // this line checks that we have a valid email address
    mail($to, $subject, $message, $headers); //This method sends the mail.
    echo "Your email was sent!"; // success message
}else{
    echo "Invalid Email, please provide an correct email.";
}
?>

上記は私のコードです。私を助けてください。ボタンをクリックすると、必須属性が機能するようにします。

これは私の意見ですが、PHP を使用して、入力フィールドが空かどうかを確認します。

それらが記入されているかどうかを確認するifステートメントを持つだけでうまくいきます。

<?php

// Here we get all the information from the fields sent over by the form.
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

if($name=='' || $email=='' || $message=='') { //Make sure all of the fields are not empty
echo "Please fill in all of the fields";
}
else { //If they are filled in, process the rest of the form

$to = 'babloopuneeth@gmail.com';
$subject = 'the subject';
$message = 'FROM: '.$name.' Email: '.$email.'Message: '.$message;
$headers = 'From: youremail@domain.com' . "\r\n";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { // this line checks that we have a valid email address
    mail($to, $subject, $message, $headers); //This method sends the mail.
    echo "Your email was sent!"; // success message
}else{
    echo "Invalid Email, please provide an correct email.";
}
}
?>
