Hello all,
Happy weekend. Hoping you can help me with an age old question.
I am trying to get a users timezone for a purchase online.
I know that php is not really able to get a timzone of a user because
its a server side execution with the date functions.
But I wanted to get a little help on my work around. I am hoping
someone
can help. TIA
I have a form that a user must fill out in order to purchase
anything.
On this form they are required to put their city, state, country
and zip
code.
These are all required fields.
Now, I know there is a way to get a timezone offset if you have a
location to offset.
So is there a way based on the fields provided that I can get that
offset for each user?
(The users have to put a correct city, state, country and zip in
order
to get there purchase.
This address has to match their paypal or cc address in order to
purchase as well.
So I know there will still be a margin of error with user manipulated
info. So that is moot point for now.)
My thoughts are to get a timezone offset based on the country and zip
code, with a backup check of city state country zip.
I just don't know where to start looking for how to get the
timezone or
UTC location based on country and zip or city state country zip.
Hi Karl,
so basically what you're looking for is a database map between
timezone and country/state/zip.
Did you try to google such a thing?
One of the first posts I found was a StackOverflow question about
this; one of the answers mentioned just such a database on Tom
Boutell's website (the same person who created the GD library [used
for image-creation in php]): http://www.boutell.com/zipcodes/
It includes states, cities, zip codes, etc. for the USA. Since you
specifically mentioned you want to find it "by state", it means
you're mainly focussing on the USA (barely any other country even
bothers with states).
Apart from the above data, I'm sure you can find more on google.
Good luck.

Thanks for the response. Yes, for the US I plan on calculating by
state, but this website is not geared to just the US.
So I am looking for a solution that lets me also calculate by country/
region.
Was looking on google and found geoip, but not sure if this will do
the job I am looking for.
Anyone with experience on geoip that can send pointers?
Thanks,
Best,
Karl DeSaulniers
