I need a form that will query google maps or whatever that will find out the distance between a set postcode and a user imported ones. Times the milage by a number, add another number and then relay that information back to the user.

Will be a fitting charge calculator based on distance from me.

Not got a clue how to do this. Anyone got any ideas?

I'd start by looking at the Google Maps API

They're straight line calculations and won't work using postcodes. To get driving directions you need to use the directions API and to use postcodes you need access to the Royal Mail postcode file.

Just had a little look, you can use the AJAX API to geocode UK postcodes accurately.

Could prob work with the straight line distances. Unless anyone can find anything that does actual milage.

Ed, using the google API and Royal Mail sounds complicated.

Could maybe use the straight line distances in a banding. 0-50miles 50-100 miles etc.

Would just be talking that script and adding a few bits i guess.

Thi shit is behond me. Might have a play but cant see me getting my head round it.

The second link noshua posted has this link in it: http://briancray.com/2009/06/23/calculate-driving-distance-google-maps-api/

Seems to work on full addresses, but postcodes have always been a bit more tricky.

Google provide this directions API:

http://code.google.com/apis/maps/documentation/directions/

Here's an example for postcode geocoding:

http://www.tomanthony.co.uk/blog/geocoding-uk-postcodes-with-google-map-api/

Google Maps stuff isn't too tricky once you get into it. It's fairly complex if you haven't worked with external API's before though!

I didnt know what API was untill now so its a bit bemusing. I think i need a few hours on the PC going through this.

Would have thought somthing like this would be availabe FOC somewhere. Sp,e guy was talking about it on the ZenCart forums but dont think anything came of it.

I've used what you posted and sorted my own Google API code etc. Ive put it up online @ gasworksair.co.uk

Now i need to remove the 1st address box and make it pre-set. Then add some extra coding so it dosent show the distances etc, It shows the 'distance * 0.4 + 55'

Any ideas how?

Nice work so far!

To round a number to two DP you do the following:

var price=150.56789823475890324;
var priceRound=Math.round(price*100)/100;

alert(priceRound);

Use this for your postcode input:

<input type="text" name="address2" placeholder="Enter Your Postcode" />

Just a bit neater

also you NEED to display a google map if you're using their API (could stick a link to a popout div etc)

Placeholder removes the 'Enter your Postcode' text from the box.
