GazChap's WooCommerce getAddress.io Postcode Lookup

This plugin enables your customers to complete their billing/shipping addresses by entering their postcode and selecting their address from the options given. It utilises getAddress.io (https://getaddress.io) to do the lookup using their Royal Mail Postcode Address File. An API key is required for the integration to work, and the integration only appears when the customer has selected United Kingdom (or, more specifically, the ISO-3166-2 code "GB") for their country. It can optionally be turned off for the shipping or billing addresses, and can be enabled or disabled in each of the checkout, customer account and WooCommerce admin screens. Postcodes that are looked up are saved in a custom database table for 24 hours to help reduce your costs for use of the getAddress.io API.

Install via the WordPress Plugin Directory, or download a release from this repository and install as you would a normal WordPress plugin.

3.0 (08/10/2023)

• Added custom database table to cache postcode results across visitors. Results are cached for 1 day before being purged in a daily cron job.
• Moved settings to their own section (at the top) in the WooCommerce -> Settings -> General tab.

• Removed notes about test postcodes from readme and settings screen, they're no longer supported.

2.3 (14/06/2023)

• Declared compatibility with WooCommerce High Performance Order Storage -- thanks benatherton for the information.

2.2 (10/02/2022)

• Stopped using elements to output the Find Address buttons, as this was causing issues with some other checkout-modification plugins like Fluid Checkout.
• Updated event listeners for the Find Address and Enter Address Manually elements so that they work if those elements are first added to the page after load.

2.1 (09/12/2021)

• Added a Hook Priority setting that can be used to try and correct conflicts caused by plugins like Checkout Field Editor Pro. Increase the priority until the lookup button comes back.

2.0.4 (15/07/2021)

• Fixed an issue with the Enter/Return key (or equivalent on mobile) submitting the entire checkout form instead of triggering the postcode lookup. Thanks to donlee101 for the report.

2.0.3 (10/06/2021)

• Fixed a bug with the new hide address fields option not functioning correctly when GB is the only country available to select. Thanks again to prodograw.

2.0.2 (10/06/2021)

• Removed reliance on certain CSS classes in the checkout, as some themes apparently don't use them. Thanks to prodograw for the report.
• Fixed a bug that would stop the "tidy postcode" routine running when looking up a postcode currently in the cache
• Removed some duplicate JS that had crept in

2.0.1 (09/06/2021)

• Somehow the push I did to the WordPress plugin repo missed some files - hopefully this will fix it...

2.0 (09/06/2021)

• Added postcode lookup to the WooCommerce admin when creating and editing orders
• Added option (disabled by default) to hide the address input fields until an address has been selected
• Added option to show an "Enter address manually" button for use in conjunction with the above "hide address fields" option
• Added new filter for changing the "Enter address manually" text
• Added link to getaddress.io in plugin settings
• Updated donation link to Ko-Fi instead of PayPal

1.5.1 (27/08/2020)

• Fix layout issue seemingly introduced by the WooCommerce 4.4 update, that pushed the "Find Address" button on to the next row.

1.5 (14/08/2020)

• The address results selector now works properly in the Account pages on the front-end. Thanks to Ben Wheeler for some additional assistance here.
• Added an additional "Searching..." state when the button is clicked for better user experience
• Added settings in WC admin panel to change the text shown on the Find Address button, and the text shown in the new "Searching..." state
• Added filters for the above texts for developer control
• The JavaScript file is now only enqueued when on the checkout or account pages, which should speed up performance of other pages.

1.4 (12/06/2020)

• Uses the postcode returned by getAddress.io to "tidy up" the postcode field after the lookup is completed. Thanks to bootle for the suggestion.

1.3 (06/05/2020)

• Updated JS to trigger WooCommerce's order update Ajax request when an address is selected. Thanks to rfvdan for the report.

1.2 (02/05/2019)

• Fixed a bug that caused the JavaScript to stop running prematurely if a particular address field was not present on the checkout page. Thanks to Max Devlin for the report.

1.1 (25/02/2019)
