So I am designing a HTML5 site and I have some data in textfields for example, "password" that I need to store into the database on the Apache server. So far I have designed a simple HTML5 site which is capable of passing data to a PHP script for the handling of server information.
If I plan to use Javascripts to implement login/registers, etc is it possible for the Javascript to parse data to my PHP script and will there be any security flaws involved by doing this? Is it also advisable/recommended to have my HTML5 page parse data directly to the PHP page for the handling of storage or are there better methods/means out there?
