I'm building a website for a new client and one of the requirements is a registration form. I'm not really into all that complicated form validation and data processing. Could anyone give me some information or help regarding best practices, making it secure etc. I'm using a client-side validation plugin called parsley.js http://parsleyjs.org/documentation.html#installation but I'm not entirely sure where to go from here in regards to getting the form to process the data, submit and send the form securely. Any advice would be great, thanks in advance.
