I had a validation form made in javascript and then I added PHP to do the same thing and now nothing works.
I know the javascript worked because I tested it, but now when I push the signup button nothing happens. It's as if the function are not getting called, but from my point of view it's supposed to work.
I don't understand. the variables are empty, the code checks the posts, assign it to the variables and calls the functions. I can't see the bug and I checked the code online.
Thank you
PHP:
<?php
$forename = $surname = $username = $password = $age = $email = "";
if (isset($_POST['forename']))
$forename = fix_string($_POST['forename']);
if (isset($_POST['surname']))
$surname = fix_string($_POST['surname']);
if (isset($_POST['username']))
$username = fix_string($_POST['username']);
if (isset($_POST['password']))
$password = fix_string($_POST['password']);
if (isset($_POST['age']))
$age = fix_string($_POST['age']);
if (isset($_POST['email']))
$email = fix_string($_POST['email']);
$fail = validate_forename($forename);
$fail .= validate_surname($surname);
$fail .= validate_username($username);
$fail .= validate_password($password);
$fail .= validate_age($age);
$fail .= validate_email($email);
echo "<!DOCTYPE html>\n<html><head><title>An example form</title>";
if ($fail =="")
