notice that on google maps you can input the address any way you like. as long as it is a valid address...google maps will read it.
In some ruby book I had seen code snippet for something like this, but with phone numbers.
Any ideas how this could be done for addresses?
in language of your choice.
EDIT:
i dont care about a "valid" address. I just want to parse an address. so that 123 fake street, WA, 34223 would be an address and so will 123 fake street WA 34223
it is not trivial task. first you have to have base of all streets, populated places and may me countries (if you want international look up). then try to find each word from input string in each list and try to find matches for all words.
You could create a regular expression that would match each format you want to accept. When one of them matches, you will know how to parse that particular string. If you think about it, there probably aren't more than 10 common formats people will use to type out an address 99.9% of the time.

I'd like to implement an app with Dart on Flutter. I'm on my first approach with this new language and for the first time I meet this problem.
My app must necessarily work with a mobile phone number. I would like to see a ban on the insertion of unse prefixed telephone numbers or, alternatively, the typing of a number with more digits than expected. For example, in Italy the figures after +39 (0039) are at most 10. I probably thought I'd separate the two parts to make it easier to distinguish between lengths (one field where you select the country and another that allows you to enter the number).
Is there, as you know, a JSON that contains exactly: - the prefix of each state, - the length of the telephone number (excluding prefix), - name, *flag and *sigla (Italy, green-white-red, IT)?
Sifting through the web a little bit, I saw that flutter should actually provide already in itself with .demoTextFieldEnterITPhoneNumber, through GalleryLocalizations to do such a job, but I didn't quite understand if it bothers to control a particular regular expression for each nation or not. Could I copy and paste a number for example? Will nationality be automatically recognized?
In the end I think that such a control, so deep, is not possible so I would just need this, so make two fields, one with a list, which at the choice automatically fills in depending on the selected prefix, and a field on which the user types his number: in case of copied and pasted number check if that string also contains a +prefix.
Thank you very much, I need a lot, since my app will mainly revolve around a correct value for this field. :)
Try using the international_phone_input or country_code_picker flutter package. They are quite easy to implement
Putting it simply, we have some Norwegian postcodes and are using the API to get their addresses and lat & long. Nothing to highbrow, but on around 10% of the postcodes. The API returns no results, here's an example:
Success for postal_code=1151:
http://maps.googleapis.com/maps/api/geocode/json?components=country:NO%7Cpostal_code:1151&sensor=false
Fail for postal_code=2066:
http://maps.googleapis.com/maps/api/geocode/json?components=country:NO%7Cpostal_code:2066&sensor=false
I have noticed that the majority appear to be for the Postboks (presuming equivalent of PO boxes in the UK).
However, it's not true for all of them.
Has anyone similar experience and or perhaps a better knowledge of Norwegian postcodes?
Thanks
I tried your given request, and I found that postal_code=2066 give you ZERO_RESULTS, If you are looking to the name Jessheim, am I right? Then I think you should use the postal_code=2069, this will give you the request that you want.
Here is the request that I used.
maps.googleapis.com/maps/api/geocode/json?components=country:NO|postal_code:2069&sensor=false
Also, I think you should know first the correct/available postal code that you used. I tried to request generally in which I did not set any country as a filter.
First, I used the postal_code=1151, and as you can see, you will find the 1151 Oslo, Norway address in the result. Which means the postal_code 1151 is available in Norway.
maps.googleapis.com/maps/api/geocode/json?components=country:|postal_code:1151
Second, I used the postal_code=2066, and you will not find any address that the country is NORWAY.
maps.googleapis.com/maps/api/geocode/json?components=country:|postal_code:2066
For additional note, if you use two components value in your request.
You need to use pipe(|) to separate them. I hope I help you with this
:)
KENDi - thanks a lot for your help and answer. I found out that Norway has two types of postcode. One is for the street addresses, the other is for postboxes (or PO Boxes in the UK) that don't have an geographical address.
Here's an example
http://adressesok.posten.no/en/postal_codes/search?utf8=%E2%9C%93&q=Molde
I have use the code given below, please copy and paste in your URL, which gives latitude and longitude of a specific place.
But when I have used the same call with wrong place it returns latitude and longitude. How to check whether it is right and wrong?
http://maps.google.com/maps/api/geocode/json?address=dubai+United+Arab+Emirates&sensor=false
http://maps.google.com/maps/api/geocode/json?address=anu+India&sensor=false
Thanks
A typical scenario for using geocoding will be when you know that the address exists and you want to get the location coordinates, maybe to mark on a map. When you search an address in google geocoding api, it will find exact matches and also partial matches to correct for cases like spelling mistakes or multiple spellings in use. Due to partial match, when you search for a word, words close to that in terms of the letters used and the number of letters present will also be found. You can explore 2 options to refine the results:
1, If you want to avoid partial matches , you can try component filtering , where you specify filters on components like locality, country , etc and only exact matches will be returned.
2, You can process the json result in your code by retreiving different components and doing comparisons and taking only cases matching your requirement.
Hi I am working on a site and integrating authorize.net payment gateway. I am thinking of adding a dropdown for country names, will passing of "United States Of America" as country variable work? Or should I use "US"? Should I use ISO codes for every country? I tried on test developer account but it seems to accept everything I passes to it as correct!
~Ajit
I know authorize.net doesn't require country names. A simple way to see if they even validate them would be to run a transaction through the production gateway, pass a nonsense value and see if the transaction still goes through.
If you do standardize to support authorize.net (or for another reason), I'd suggest country codes versus full names. Codes seem to change less often, and also can be useful as identifiers. For example, I have an application which presents data for roughly 200 countries; I have flag icons (multiple sizes for each country) that use a 2 digit country code in their name. Using codes made this fairly easy to implement and maintain.
According to their AIM Guide:
x_country: Optional
Value: The country of the customer’s billing
Format: Up to 60 characters (no symbols)
I have an address string in MySQL that has been mashed together from the source. I think it is possible to use a regular expression or some other method to seperate the string into usable parts in MySQL, but I am not aware of how this could be acheived.
Basically each string looks something like these examples (I have added a marker to the top to show what each bit is):
<-------------><-------><-><-->
123 Fake StreetRESERVOIRVIC3001
<-----------------><--------------------><------><-><-->

<-------------------><-------------------><--- ><><-->

The address supposed to be broken up into optionally two lines of address information, suburb, state and post code. I'm in Australia so the state will be either NSW,VIC,QLD,WA,SA,NT or ACT and the postcode will always be a 4 digit number at the very end.
The possible ways to break it up are that the suburb will always be capitalised, the state and postcode will be predicatable within the last 6 or 7 characters (depending on state) and the first two lines of address information will be broken up by a change in case with no space character in between.
I have some 100,000 records like this, so to go through and do it by hand would be very time consuming. Any help on a way of doing this programatically would be much appreciated.
With no spaces? Most gross...
MySQL doesn't have the tools to deal with that, so you'll have to access the database with an external program. I tend to use Perl for manipulations like this.
Start from the end and work backwards... we know the last four should be digits, and the letters preceding that one of 7 options. Use that knowledge and you'll be down 2 fields and 6-7 characters.
It looks like your example now has a town in all capital letters at the end... Parse out that, and it should match to the state and area code. I'm certain you can find a database of zip codes within some minutes online.
With the name and street address remaining, that will have some variability to it, and I wish you a bit of luck there. You may have a head-start with being able to concentrate on the lack of a space between a lowercase and capital, or a letter and number as a breaking point.
Challenge accepted. I'll even throw in some basic punctuation to allow for "101 St. Mark's St." and the like.
/^(([\w\'\.](?=[a-z \'\.])| )+[a-z\'\.])?(([\w\'\.](?=[a-z \d\'\.])| )+[a-z\.\'])([A-Z]+)(NSW|VIC|QLD|WA|SA|NT|ACT)(\d{4})/
Could probably use a little more clean-up, but it should work in any language which supports basic regex with lookahead (some implementations, like JavaScript's and (I think) Ruby's, support lookahead, but not lookbehind). (That, and this puzzle kept me up well past my bed time.) At the very least, it worked on the three examples you provided.
By the way, 2problems.com is a great site for quickly testing regular expressions. It's what I used to work this puzzle out. The guy who built it must have been a real genius. (koff koff)
Rubular is another good option, though since it works by making Ajax calls to a Ruby script behind-the-scenes, it's a bit slower. It does have the nice feature of being able to link to entered patterns and haystacks, though; here's this pattern on Rubular. The 2problems guy really should get around to implementing something like that some day.
