Building CMS system for Smiths Motor Co. & Smiths Group

Have been hired and custom build a CMS system for their brand new website template. Pretty much everything is blank, and I am so under paid… But anyway, I like doing it, and good at it anyway.

CMS system is up and running in no time, great work to me. MySQL PHP Ajax CSS, way it is now, gotta catch the fashion here.

I will post some sample coding examples that I gave me hard times, and all solved in the end.

Have anybody out there that does programming contracts by themselves? There are going to a lot people I think. Not a very reliable job, but makes some good money.

As for now, project getting to the end, and everything is up and running, and testing in a internal linux box. By end of this week, we will upload everything to Melbourne located data centre.

It is coding time, gotta fix some ridiculous error requests, which it is perfectly working as it is.
