The project includes upgrading the previous project "Joomla Community Builder register/login plugin"
1. I made an additional field "Fields" where you can basically put some keywords (comma separated). They are inserted into "pra_rbid_tags_map" table. I want to have an "active input" function like on "https://www.freelancer.com/buyers/create.php": when you start writing in the field "Enter some skills that relate to the project:" you get the list of all skills that include the string you just written.
2. I need not only java script field check, but also php field check. If somebody has java script turned off in his browser, he can input just anything (or nothing) into the fields, which I would like to avoid.
