I think I've jumped off the long board in the shallow end, LoL. I've written what I think to be a pretty decent piece of code. I've got it checking for mistakes. Now, I can't seem to figure out how to make a check to see if all is good so I can move onto the mysql checks. Any advise would be helpful.
Is there an easier way to do this. I mean the way I am trying to do it?? I just want the error next to the form input. I want to do a check to see if all fields are filled and met. Then I want to check mysql for duplicate name, and such. I'm pretty sure I could write the code for that. But I need something small that checks one function before I can get to the mysql phase. Am I making any sense?
