I am looking for any good books, tutorials, etc.
I usually do more procedural coding than OOP although I'm trying to change that.
My really good friend wants to hire me to do work on their website, and the work is simple. His website allows volunteers to enter their information, and apply for a volunteer spot.
Currently the info. they request is emailed to the admin.
He wants me to make it so users can login/register and have their info. saved so they can easily volunteer for other positions and re-use their information without having to re-enter it each and every time.
I was going to very easily make a membership site addon for his current website until he told me it's a WordPress site. Now I have no idea where to begin but he already paid my phone bill for me before telling me it was a WordPress site, so now I don't know how to proceed. I figure if I know PHP/MySQL I should be able to figure out how to accomplish what he is asking (which isnt a difficult task) and create a plugin for WordPress, right? I've never done this before or even used WordPress so any tutorials, hints, tips, suggestions would be helpful.
I've downloaded a copy and unzipped it and began looking at the file structure so far, that's about all I've done but I'm nervous that I won't be able to figure this out. If it was a website that I built, I could easily figure out where I want to create a link on the menu, and then create a page with a database connection to record the users data, etc. but being WordPress I'm not sure where to begin whatsoever.
