[SOLVED] zip code

[jakebur01]

Hello,

 

I have this code that returns the distance between two zip codes and will return a radius of zips within so many miles.

 

I am wanting to add onto this code to have it select from a new table that I have all of the rows of zip codes within that range. This new table would have name, address, zip, ect.

How could I add onto this code to have it retrieve all of the zip codes within radius from another table?

[jakebur01]

Could someone please help me with this?

[boo_lolly]

have you made any attempts yourself?

[jakebur01]

No, I need some direction. I don't know where to start. I was hoping someone could help walk me through some of it.

[jakebur01]

Am I in the wrong place looking for help on this?

 

[boo_lolly]

this is a forum. which means when anybody replies to a post, it is because they have the time to reply. if you demand attention, you will get none. if i were you, i'd start with the links in my signature under basic. you can also contact the people who wrote the script and ask them, or request to add this feature to the next version of this application.

 

also, what do you mean by 'radius in another table'?

[jakebur01]

I am wanting to add a table to my MYsQL Database. With the colums Dealer, Address, City, State, Zip. I am wanting to use this code to find the dealers within a certain radius, depending on what zip code the user types in.
