Post Office CASS Address Verification module

[audleman]

Hi Zenners,

I've developed some code for ZenCard that will scrub the address a customer inputs via the United States Post Office CASS Address Verification API. If you want to see it in action, try filling in a gift subscription on this page:

If you enter a correct address, on the shopping cart page you will see that the address is in the correct format, including zip+5. If you enter a bad address, you will see a prompt that alerts you to a problem with the USPS and asks if you want to correct the address or continue with it as entered.

I did a search on this forum and didn't see that anybody had developed something like this before. So I thought I'd put it out there and see if anybody is interested in having me wrap this code up into a module and making it open source. If you're interested, let me know.

I would like to see it, I have a site I could use this on.

Please package the module and add it to the Free Add Ons section, I am sure it will be useful to many folks.

I am developing a site right now and am very close to going live. I have been looking for exactly this kind of mod. Please post as soon as you can so that I might be able to put it on our new site. Very excited. Thanks.

Hi gang,

I just finished wrapping up my code into a module. Here it is in beta form. I would call it a very strong beta, as I've been running the code on my site for almost a year (I just don't know what little issues might come up when somebody installs it fresh).

It is a very easy install as it doesn't touch any core files. Give it a go and let me know if you have any issues. I'll be happy to help debug them.

Cheers,
Kevin

Hello,

Please use this new version 1.1. It fixes a problem where the sql patch file was missing a configuration value that allows you to toggle the module on/off!

Cheers,

Thanks to Jason for discovering a hard-coded table name in a sql query. Download the latest version, v 1.2, for a fix. If you want to make the fix yourself, go into the file

/includes/classes/observers/class.cass_validation.php

Around line 73 you will see this line:

$zone_query = "SELECT zone_code FROM zen_zones WHERE zone_id = " . $cass_address->fields['entry_zone_id'];

Replace it with this one:

$zone_query = "SELECT zone_code FROM ".TABLE_ZONES." WHERE zone_id = " . $cass_address->fields['entry_zone_id'];


Cheers,

Hi Kevin,
Sorry it took me so long to get back to this.
I have the mod installed. My site is live.
Everything seems to be working just fine.
It's really great.
Thank you for the contribution.

Just a note to anyone else looking to install this mod:
The USPS process may indeed be quite tiresome.

Be sure to only check the top box. All of the rest are invalid uses of the API. I don't know why they feel like they need to quiz the customers. Anyhow, if you pick more than the top box, you'll have to beg and plead and explain yourself. Then maybe they'll let you in.
Also, do not expect quick service, friendly communication, or a helpful staff. So as long as you're prepared, no worries. Just be patient.

Cheers.
Jason

While I can be patient. I have a client that might not be. How soon after you put in the request form did you get a response. I'm hoping I receive an email affirmative that will let me know when I can configure everything else.
