Question

How can I validate my form without using JavaScript? I have used the required HTML 5 attribute but as IE doesn’t support IE (ANNOYING) is there a way around this with using PHP which will take time.

Thanks

You should always validate on the server side (e.g., with PHP). There are probably a lot of libraries that will make this easier and save you some time, but the principle’s pretty simple:

if (isset($_POST['submit'])) {
   $name = isset($_POST['name']) ? $_POST['name'] : null;
}
$errors = '';
if (!$name or strlen($name) < 5) {
   $errors .= 'Name must not be empty and at least five characters';
}
if ($errors) {
   echo $errors;
}
else {
   //Store data from the form or whatever you want to do.
}

I would also recommend using Post/Redirect/Get
