note 62782 rejected from function.is-int by betz

Note Submitter: elaineseery at hotmail dot com ---- i had learnt the hard way that all form input is submitted as a string - but maybe not always? the example below works without casting $_POST['age'] as an int... <?php // retrieve form data $age = $_POST['age']; // check entered value and branch if ($age >= 21) { echo 'Come on in, we have alcohol and music awaiting you!'; } else { echo 'You\'re too young for this club, come back when you\'re a little older'; } ?> <form id="form1" name="form1" method="post" action=""> <label for="age">Your Age</label> <input type="text" name="age" id="age" /> <input type="submit" name="Submit" value="Submit" id="Submit" /> </form>
