Creating simple Q&A site but don't know a lot about PHP + mySQL?

You can see what i'm trying to do at http://askanswerdone.zxq.net/ basically, I'm making a site where users come, enter in the type of question they have, the type of question they'll answer, and then they get connected automatically with someone who said that they开发者_开发问答 would answer the same type of question they have, and someone that was asking a question in the same type as you. I want to do this but know near-nothing about PHP and mySQL. Can anyone help me understand how to write to the database and delete a row when finished? Also, can anyone help me figure out how to do the chat portion? Thanks.

I would attempt to use one of the open source CMS platform out there.

Wordpress, Joomla and Drupal are well known.

Wordpress has a few plugins that do that automatically. You may have to research which is best:

http://wordpress.org/extend/plugins/search.php?q=questions&sort=

Also I know Drupal can do this for sure with it's structure and it also has modules that look like they can do it too:
http://drupal.org/search/apachesolr_multisitesearch/questions?filters=ss_meta_type%3Amodule

Both look like the would work on your host. Which one you choose is more about opinion but I feel that Wordpress is easier to get started with but less flexible, whereas Drupal is overly more powerful but involves more of a learning curve.

Whilst it avoids learning php/mysql directly, I actually learnt php and mysql via customising and using those CMS, so they can also be a nice way into php if you don't consider yourself the programming type.
