this is not guaranteed to be free from bugs or security flaws, as it should say in the license, but it seems like a helpful start towards html form automation. it can be paired with a javascript frontend validator. the server side validation class is not very robust at this point, and the function that translates the regex from javascript (html5 pattern attribute) to php has not been thoroughly tested. in fact, the whole application has not been thoroughly tested. please feel free to leave feedback and possibly get involved. thanks(!)
