Laravel Postcodes is a package by Steve McDougall that provides a validation rule and macro for validating post codes. The package uses the postcodes.io service—a free and open-source API—for looking up geocoded UK postcodes.
There are three ways to interact with postcodes using this package. First, you can use the provided validation rule:
use JustSteveKing\LaravelPostcodes\Rules\Postcode; $this->validate($request, [ ‘postcode’ => [ ‘required’, ‘string’, new Postcode() ] ]);
Second, you can use the provided macro:
$this->validate($request, [ ‘postcode’ => [ ‘required’, ‘string’, Rule::postcode() ] ]);
Third, this package defines a service for interacting with the API directly:
use JustSteveKing\LaravelPostcodes\Service\PostcodeService; app(PostcodeService::class)->getPostcode($postcode);
You can learn more about this package, get full installation instructions, and view the source code on GitHub at JustSteveKing/LaravelPostcodes.
