Laravel Postcodes

Now we can do this example how it works Laravel 6 postcodes validation rule. The package uses the postcodes.io service a free and open-source API for looking up geocoded UK postcodes. Laravel 6 provides a validation rule and macro for validating postcodes. There are three ways to communicate with postcodes using this package. In this example, I will explain to you step by step 3 ways to communicate with Laravel 6 postcodes validation. This package validation is used to you can check postal code validation on for UK geocoded. Now we will start this example.

Step 1 : Install Package

open your command line and follow this command.

composer require juststeveking/laravel-postcodes

After the installed this package, merge configuration for services using.

php artisan vendor:publish --provider="JustSteveKing\LaravelPostcodes\PostcodesServiceProvider"

Step 2 : Add the following code

config/services.php

If, for some reason postcodes not working following below steps.

<?php
'postcodes' => [
    'url' => env('POSTCODES_URL', 'https://api.postcodes.io/')
],

Add POSTCODES_URL to your project .env file and add this line https://api.postcodes.io/ as the value.

.env

POSTCODES_URL=https://api.postcodes.io/

Step 3 : Basic Use

Here, we can use three methods right now we do that.

Method 1

Now we can use validation rule.

<?php

$this->validate($request, [
    'postcode' => [
        'required',
        'string',
        new Postcode()
    ]
]);

Here we can use second method.

Method 2

$this->validate($request, [
    'postcode' => [
        'required',
        'string',
        Rule::postcode()
    ]
]);

If you want to communicate with the service itself.

Method 3

<?php 
class PostController extends Controller
{
    protected $postcodes;

    public function __construct(PostcodeService $service)
    {
        $this->postcodes = $service;
    }

    public function store(Request $request)
    {
        // validation using example above
        $location = $this->postcodes->getPostcode($request->postcode);
    }
}
