I have a web site at [url removed, login to view] This is a listing site that has been made to search on US Zip Codes. I am in England and want it to work on English Post Codes that are long and unnecessary. I want people to use the search feature where they will put the whole code in ( example OX14 8NR) but the match is only against the first 4 digits. There is an added complication that some post codes in England are like this OX1 8NR only having 3 digits then a space. At the moment it will work if you only put the first 4 digits in. However, people are used to putting in their complete code so I want them to be able to do that.
So want I want is the programme changed so it will recognize just the first 3 or 4 digits and work. Can you do this?
