README
Remember a visitor's original referer, utm tags in cookies.
Installation
You can install the package via composer:
composer require abhij89/utm-referer
The package will automatically register itself in Laravel 5.5. In Laravel 5.4. you'll manually need to register the Abhij89\UTMReferer\UTMRefererServiceProvider
service provider in config/app.php
.
You can publish the config file with:
php artisan vendor:publish --provider="Abhij89\UTMReferer\UTMRefererServiceProvider"
Publishing the config file is necessary if you want to change the keys in which the referer/utms are stored in the cookie or if you want to disable a referer/utm source.
return [ /* * The key that will be used to remember the referer in the cookie. */ 'referer_cookie_key' => 'user-referer', /* * The key that will be used to remember the utm tags in the cookie. */ 'utm_cookie_key' => 'user-utms', /* * The sources used to determine the referer/utms. */ 'sources' => [ Abhij89\UTMReferer\Sources\UTMSource::class, Abhij89\UTMReferer\Sources\RequestHeader::class, ], ];
Usage
To capture the referer, all you need to do is add the Abhij89\UTMReferer\CaptureReferer
middleware to your middleware stack. In most configuration's, you'll only want to capture the referer in "web" requests, so it makes sense to register it in the web
stack. Make sure it comes after Laravel's StartSession
middleware!
// app/Http/Kernel.php protected $middlewareGroups = [ 'web' => [ // ... \Illuminate\Session\Middleware\StartSession::class, // ... \Abhij89\UTMReferer\CaptureReferer::class, // ... ], // ... ];
The easiest way to retrieve the referer is by just resolving it out of the container:
use Abhij89\UTMReferer\UTMReferer; $referer = app(UTMReferer::class)->get(); // 'google.com'
Or you could opt to use Laravel's automatic facades:
use Facades\Abhij89\UTMReferer\UTMReferer; $referer = UTMReferer::get(); // 'google.com'
An empty referer will never overwrite an exisiting referer. So if a visitor comes from google.com and visits a few pages on your site, those pages won't affect the referer since local hosts are ignored.
Forgetting or manually setting the referer
The Referer
class provides dedicated methods to forget, or manually set the referer.
use Referer; Referer::put('google.com'); Referer::get(); // 'google.com' Referer::forget(); Referer::get(); // ''
Changing the way the referer is determined
The referer is determined by doing checks on various sources, which are defined in the configuration.
return [ // ... 'sources' => [ Abhij89\Referer\Sources\UtmSource::class, Abhij89\Referer\Sources\RequestHeader::class, ], ];
A source implements the Source
interface, and requires one method, getReferer
. If a source is able to determine a referer, other sources will be ignored. In other words, the sources
array is ordered by priority.
In the next example, we'll add a source that can use a ?ref
query parameter to determine the referer. Additionally, we'll ignore ?utm_source
parameters.
First, create the source implementations:
namespace App\Referer; use Illuminate\Http\Request; use Abhij89\Referer\Source; class RefParameter implements Source { public function getReferer(Request $request): string { return $request->get('ref', ''); } }
Then register your source in the sources
array. We'll also disable the utm_source
while we're at it.
return [ // ... 'sources' => [ App\Referer\RefParameter::class, Abhij89\Referer\Sources\RequestHeader::class, ], ];
That's it! Source implementations can be this simple, or more advanced if necessary.
