=================== (http://jqguess.net/electronicsupply)
This is a Repo for a site I built a while back that uses PHP and MySQL.
I recently reworked the site to be responsive using bootstrap. The Sign Up and Login system are secure and active using respective classes for operation. I added a comment section that uses a PDO db connection along with current security measures. I would suggest having your users login before posting, because this solution is mainly for demonstration.
I fully intend on using this site in the near future to create a web solution for a similar company that could use an upgrade.
Until that point in time, I will likely keep improving this site so that all I will need to do is plug in real data for the inventory he sells and reconfigure the database as needed.
