Google Tag Manager allows you manage tracking and marketing optimization with AdWords, Google Analytics, et al. without editing your site code. One way of using Google Tag Manager is by sending data through a dataLayer variable in javascript after the page load and on custom events. This package makes managing the data layer easy.
For concrete examples of what you want to send throught the data layer, check out Google Tag Manager's Developer Guide.
You'll also need a Google Tag Manager ID, which you can retrieve by signing up and creating an account for your website.
You can install the package via Composer:
$ composer require spatie/laravel4-googletagmanagerStart by registering the package's the service provider and facade:
// app/config/app.php (L4)
'providers' => [
...
'Spatie\GoogleTagManager\GoogleTagManagerServiceProvider',
],
'aliases' => [
...
'GoogleTagManager' => 'Spatie\GoogleTagManager\GoogleTagManagerFacade',
],The facade is optional, but the rest of this guide assumes you're using the facade.
Next, publish the config files:
// L4
$ php artisan config:publish spatie/googletagmanager --path="vendor/spatie/laravel4-googletagmanager/resources/config"Optionally publish the view files. It's not recommended to do this unless necessary so your views stay up-to-date in future package releases.
// L4
$ php artisan views:publish spatie/googletagmanager --path="vendor/spatie/laravel4-googletagmanager/resources/views"The configuration file is fairly simple.
return [
'id' => '',
'enabled' => true,
];During development, you don't want to be sending data to your production's tag manager account, which is where enabled comes in.
Example setup:
return [
'id' => 'GTM-XXXXXX',
'enabled' => app()->environment() === 'production',
];First you'll need to include Google Tag Manager's script. Google's docs recommend doing this right after the body tag.
{{-- layout.blade.php --}}
<html>
{{-- ... --}}
<body>
@include('googletagmanager::script')
{{-- ... --}}
</body>
</html>
Your base dataLayer will also be rendered here. To add data, use the set() function.
// HomeController.php
public function index()
{
GoogleTagManager::set('pageType', 'productDetail');
return view('home');
}This renders:
<html>
<!-- ... -->
<body>
<script>dataLayer = [{"pageType":"productDetail"}];</script>
<script>/* Google Tag Manager's script */</script>
<!-- ... -->
</body>
</html>// Retrieve your Google Tag Manager id
$id = GoogleTagManager::id(); // GTM-XXXXXX
// Check whether script rendering is enabled
$enabled = GoogleTagManager::isEnabled(); // true|false
// Enable and disable script rendering
GoogleTagManager::enable();
GoogleTagManager::disable();
// Add data to the data layer (automatically renders right before the tag manager script). Setting new values merges them with the previous ones. Set als supports dot notation.
GoogleTagManager::set(['foo' => 'bar']);
GoogleTagManager::set('baz', ['ho' => 'dor']);
GoogleTagManager::set('baz.ho', 'doorrrrr');
// [
// 'foo' => 'bar',
// 'baz' => ['ho' => 'doorrrrr']
// ]GoogleTagManager also has a dump() function to convert arrays to json objects on the fly. This is useful for sending data to the view that you want to use at a later time.
<a data-gtm-product='{!! GoogleTagManager::dump($article->toArray()) !!}' data-gtm-click>Product</a>
$('[data-gtm-click]').on('click', function() {
dataLayer.push({
'event': 'productClick',
'ecommerce': {
'click': {
'products': $(this).data('gtm-product')
}
}
'eventCallback': function() {
document.location = $(this).attr('href');
}
});
});Internally GoogleTagManager uses the DataLayer class to hold and render data. This class is perfectly usable without the rest of the package for some custom implementations. DataLayer is a glorified array that has dot notation support and easily renders to json.
$dataLayer = new Spatie\GoogleTagManager\DataLayer();
$dataLayer->set('ecommerce.click.products', $products->toJson());
echo $dataLayer->toJson(); // {"ecommerce":{"click":{"products":"..."}}}If you want full access to the GoogleTagManager instances' data layer, call the getDataLayer() function.
$dataLayer = GoogleTagManager::getDataLayer();Adding tags to pages can become a repetitive process. Since this package isn't supposed to be opinionated on what your tags should look like, the GoogleTagManager is macroable.
GoogleTagManager::macro('impression', function ($product) {
GoogleTagManager::set('ecommerce', [
'currencyCode' => 'EUR',
'detail' => [
'products' => [ $product->getGoogleTagManagerData() ]
]
]);
});
GoogleTagManager::impression($product);Please see CHANGELOG for more information what has changed recently.
