Undefined index - PHP (Help please?)

    So, I tried this:
    <form name "form1" method "post" action="checklogin.php">
    input type="text" name="email" placeholder="Email">
    input type="password" name="pass" placeholder="Password">
    input type="submit" name="login" class="login login-submit" value="login">
    Just making a simple login form, then in checklogin.php I try this:
    There is no problem with pass, however for email I get the error:
    Notice: Undefined index: mail in C:\wamp\www\mailservice\checklogin.php on line 13
    $email=$_POST['email']; is the piece of code on line 13.
    Any help?

    Undefined index: mail your calling mail as a variable somewhere

    Sorry, I tested it by changing it to mail instead of mail at one point, the copy paste was from when I did that.
    Refreshing the page it is now email, same error though.

    Right, that helped, thanks.
    Seems that it isn't being recognised as email, but as user.
  6. Validate and sanitize your $_POST input should be a thing to consider.

    $email = (isset($_POST['email']) ? $_POST['email'] : false);

    Then you can successfully do stuff like if($email) {} without it crying out errors everywhere. Sanitization depends on what you use for storage or whatever. htmlspecialchars() is a thing you should use, too.

    Good luck. :)
