  1. I’m new to php and MySQL, and i'm just getting my feet dirty... Basically i am working on a message board, i need to be able to post a thread like you would do normally and also ask for post code, to be stored with the thread. Then I want to modify search.php and create a field where you type post code of your liking and have it compared WITH thread post code and then calculate the distance between post code in a thread and post code you type into search Does that make sense? How do I go about that?. Here’s a good one: http://www.geopostcode.org.uk/findmynearest.php Any thing else? Oh and I need a UK version of this (for now) as you probably guessed!
  2. Ahhhhhhhhhhhhhhhh it works!!!! Good **** !!! Thanks so much for helping me out
