Installation

You can install the package via composer:

composer require astrogoat/gtm

If you plan on using the flash-functionality you must install the GoogleTagManagerMiddleware, after the StartSession middleware:

// app/Http/Kernel.php

protected $middleware = [
    ...
    \Illuminate\Session\Middleware\StartSession::class,
    \Spatie\GoogleTagManager\GoogleTagManagerMiddleware::class,
    ...
];

Usage

This will require two includes to be added to BRAND/layout/app.blade.php

<head> 
    ...
    @include('gtm::header-script')
</head>

<body>
    ...
    @include('gtm::body-script')
</body>

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>
  <head>
    <script>dataLayer = [{"pageType":"productDetail"}];</script>
    <script>/* Google Tag Manager's script */</script>
    <!-- ... -->
  </head>
  <!-- ... -->
</html>

Flashing data for the next request

The package can also set data to render on the next request. This is useful for setting data after an internal redirect.

// ContactController.php

public function getContact()
{
    GoogleTagManager::set('pageType', 'contact');

    return view('contact');
}

public function postContact()
{
    // Do contact form stuff...

    GoogleTagManager::flash('formResponse', 'success');

    return redirect()->action('ContactController@getContact');
}

After a form submit, the following dataLayer will be parsed on the contact page:

<html>
  <head>
    <script>dataLayer = [{"pageType":"contact","formResponse":"success"}];</script>
    <script>/* Google Tag Manager's script */</script>
    <!-- ... -->
  </head>
  <!-- ... -->
</html>

Other Simple Methods

// Retrieve your Google Tag Manager id
$id = GoogleTagManager::id(); // GTM-XXXXXX

// Check whether script rendering is enabled
$enabled = GoogleTagManager::isEnabled(); // true|false

// Add data to the data layer (automatically renders right before the tag manager script). Setting new values merges them with the previous ones. Set also supports dot notation.
GoogleTagManager::set(['foo' => 'bar']);
GoogleTagManager::set('baz', ['ho' => 'dor']);
GoogleTagManager::set('baz.ho', 'doorrrrr');

// [
//   'foo' => 'bar',
//   'baz' => ['ho' => 'doorrrrr']
// ]
