PHP / MySQL help required

I need someone to check what has been built/coded so far (most of the site is in place), to work out why data is not being passed from the PHP code to the backend database. (for example, the registration and login functions, as well as the posting data) and to fix this.

The site is to be 'keyword-driven' therefore, i also need a search function built that returns posted 'items' containing the requested keyword in the title

There may be a couple of other small tasks that come up.

The deadline for getting this done is by 2009 - as i think you can see, this is really only a few small tasks that should not require too much time / effort

For more info, please ask
