There are no form 'wheels' as such. What you want to do is essentially the metal of the wheels.
You are trying to do the oldest, widest of use action in PHP. What you are trying to do is (in my opinion) what PHP is best for. This is why PHP was invented!!
ok maybe a lil OTT but if you read up on it, PHP started with some guy wanting to have a guestbook on his site and it was called Personal Home Page - Internet Tools (PHP-IT)
ANYWAY
There must be thousands of articles all over the web on this. Just becareful as recently in PHP 4-5, something in PHP called global variables have been turned off by default so older article will be teaching a method that is highly unrecommended.
STFW 😃 (i've been waitin for a chance to say that!)
If you need help on what to look for, yoiu want to look for 3 things in this order:
1. PHP forms using post method
there are 2 methods. POST and GET.
2. Setting up the database. Depending on how your set up...you need to know how to firstly start a new table##.
3. Saving the data to database.
If you don't have SQL database access right now, I can supply some scripts that allow you to store membership names to a text file known as a flat-file database. It is a simple means of storing information sent by a form for small and simple things such as a membership.
I can supply scripts that save data to file, retrieve data, modify specific entries etc. I have this project underway mysefl so it isn't completely available. Can rush upon request but please exhaust above search options first. Find for yourself the way of the SQL before attempting the coward's route of the flat file :xbones:
