Hello, I need this little project as soon as possible. I'm using an open-source code right now, and I need to add in the model 4 different new objects ( WHEN, THEN, AND, GIVEN) and colors too. (I was thinking of taking as an example the Nyan Cats/colors example) It's a pretty straightforward little project. You have plenty of examples on the website. If possible, you will need to give me four nice little icons, basically a square with the word. All the code etc., is on the website.

I wrote a simple PHP analytics script (only 77 lines of code including commenting). It does the following: a) Gathers the URL, timestamp, IP address, and browser of a visitor. b) Extracts a unique customer identifier from the URL. c) Inserts the data into a MySQL database. The script works fine as a standalone script, but I want to be able to embed it into Wordpress pages on a few different websites (that can all access the same MySQL database). I don't care how this problem is solved. I only care that it is fast, simple, and secure so it doesn't make the sites vulnerable to attack. You could: 1) Make it work in PHP as a server side script, modifying it to work with Wordpress. Or 2) Port it to Javascript to make it work as a client side script, possibly? I'm not a professional coder. You tell me the best way to do this.
