Add personalization to your Laravel website

Add customers to segments

For this setup we'll make use of the Electric Car Lovers segment in the Acme lease demo data. Make sure that the segment in your Prepr environment includes the condition, Customers who did view specific items, Electric Lease Landing Page.

If you need more details, checkout the Segments docs.

You previously enabled Prepr tracking in your website. This means a customer gets added to the Electric Car Lovers segment whenever they view the Electric Lease Landing Page content item.

You can test this with the following steps:

1. Go to http://localhost:8000/electric-lease to open the electric lease landing page in your website.

   

2. In your Prepr environment, go to the Segments page and click the Electric Car Lovers segment. You should see matching customers in this segment like in the image below.

   

To make sure that customers in the Electric Car Lovers segment see the matching adaptive content when they visit the home page, you need to set the API request header, Prepr-Customer-Id, when you retrieve the page content. Based on this value, Prepr will check the segment that this customer belongs to and will retrieve the matching personalized variant.

The Prepr tracking pixel you added in the previous section, assigns each visitor a unique ID with a cookie called __prepr_uid. You can use the __prepr_uid value to set the Prepr Customer ID.

1. Go to the bootstrap folder and add the highlighted code below to the app.php file.

   ./bootstrap/app.php

   <?php
    
   use Illuminate\Foundation\Application;
   use Illuminate\Foundation\Configuration\Exceptions;
   use Illuminate\Foundation\Configuration\Middleware;
    
   return Application::configure(basePath: dirname(__DIR__))
       ->withRouting(
           web: __DIR__.'/../routes/web.php',
           commands: __DIR__.'/../routes/console.php',
           health: '/up',
       )
       ->withMiddleware(function (Middleware $middleware) {
           $middleware->encryptCookies(except: [
               '__prepr_uid',
           ]);
       })
       ->withExceptions(function (Exceptions $exceptions) {
           //
       })
       ->create();

2. Go to the app/Http/controllers folder and add the following code to the PageController.php to get the __prepr_uid cookie value and use it to set the API request header Prepr-Customer-Id.

   ./app/Http/controllers/PageController.php

   <?php
    
   namespace App\Http\Controllers;
    
   // Include Http to make the query request
   use Illuminate\Support\Facades\Http;
    
   //Include to get cookie from request
   use Illuminate\Http\Request;
    
   class PageController extends Controller
   {
       public function index(Request $request, $slug='/')
       {
           $response = Http::prepr([
               'query' => 'get-page-by-slug',
               'variables' => [
                   'slug' => $slug,
               ],
               'headers' => [
                   'Prepr-Customer-Id' => $request->cookie('__prepr_uid')
               ]
           ]);
       
           $page = data_get($response->json(), 'data.Page');
       
           // Return the page view with query response
           if ($page) {
               return view('pages.index', [
                   'page' => $page,
               ]);
           }  
       }
   }

Test your adaptive content

Now that people who visit the Electric lease landing page are being grouped into the Electric Car Lovers segment, you can test the adaptive content. To test the adaptive content for the Electric Car Lovers segment follow the steps below.

1. Go to the Electric Car landing page in your website. For example: http://localhost:8000/electric-lease.

2. Wait a few seconds and go back to the home page. You can now see the personalized home page like in the image below.

   

To see the non-personalized page, you can reset the cookies and refresh the page as follows:

3. Right-click the page to Inspect the page, click the Application tab. Under the cookies, click your localhost. You'll notice the __prepr_uid cookie in the list.

4. Right-click the localhost entry to Clear the cookies and refresh the page. You should now see the non-personalized content in the home page.

   

Add HTML attributes to track impressions and conversion events

Your personalization is running successfully, however there are no metrics being recorded yet. You can see this with the Awaiting data message at the top of the Adaptive content block in the Homepage content item.

To get Prepr to start showing some metrics data, you need to add HTML attributes to elements in your adaptive content. When you add these attributes, the tracking code you added in the previous section automatically tracks impressions and your chosen conversion events.

1. To start collecting impressions and clicks, add the HTML attributes data-prepr-variant-key and data-prepr-variant-event to the Hero section as shown in the highlighted code below. The impression is recorded when the Hero element scrolls into view. The click is recorded when the button is clicked.

   ./resources/views/components/hero-section.blade.php

   <section class="bg-primary-50" data-prepr-variant-key="{{ data_get($data,'_context.variant_key') }}">
       <div class="mx-auto max-w-8xl p-spacing flex flex-col items-center md:flex-row gap-8 py-10 lg:py-20">
           <div class="basis-6/12">
               <h1 class="text-mb-5xl lg:text-7xl text-secondary-700 font-medium break-words text-balance">
                   {{ data_get($data,'heading') }}
               </h1>
               <p class="text-mb-lg text-secondary-500 lg:text-lg mt-4 lg:mt-6 text-balance">
                   {{ data_get($data,'sub_heading') }}
               </p>
               <div class="flex gap-4 mt-8 xl:mt-10">
                   <div>
                       <a href="#" data-prepr-variant-event><x-button>Find your car</x-button></a>
                   </div>
               </div>
           </div>
           <div class="basis-6/12 relative flex justify-end items-center">
               <div class="z-10 flex items-center aspect-[20/17] w-9/12 overflow-hidden justify-center absolute top-1/2 left-1/2 transform -translate-x-1/2 -translate-y-1/2">
                   <img src="{{ data_get($data,'image.url') }}" alt="Hero Image" class="object-cover rounded-2xl" />
               </div>
               <div class="w-9/12 aspect-[20/17] bg-primary-100 rounded-3xl right-0 top-0 z-0"></div>
           </div>
       </div>
   </section>

2. To start recording metrics, go to the home page in your website, click the Find your car button.

3. Now when you view the adaptive content in your Homepage content item, you can click the Metrics link and see the number of impressions and clicks like in the image below.
