Helick Google Tag Manager

Google Tag Manager integration.

Requirements

Make sure all dependencies have been installed before moving on:

• PHP >= 7.1
• Composer

Install

Install via Composer:

$ composer require helick/gtm

Update your application config by declaring the following:

Config::define('GTM_CONTAINER_ID', env('GTM_CONTAINER_ID'));

Update your env variables by declaring the following:

GTM_CONTAINER_ID=GTM-XXXX

Usage

To support the fallback iframe for devices without javascript add the following code just after the opening <body> tag in your theme:

<?php wp_body_open(); ?>

Data layer

Google Tag Manager offers a data layer which allows you pass arbitrary data that can be used to modify which tags are added to your site.

This plugin adds some default information such as post, tags and categories and provides a simple filter for adding in your own custom data.

add_filter('helick_gtm_data_layer', function (array $dataLayer) {
    $dataLayer['foo'] = 'bar';

    return $dataLayer;
});

Event tracking

To deactivate the event tracking you may declare the following:

add_filter('helick_gtm_enable_event_tracking', '__return_false');

By default the event listener script will look for the elements on the page with special data attributes in your markup and listen for the specified event to push to the data layer.

The data attributes are:

• data-gtm-variable string Optionally override the default data layer variable name for this event.
• data-gtm-on enum [click|submit|keyup|focus|blur] The JS event to listen for, defaults to 'click'.
• data-gtm-event string The event name.
• data-gtm-category string Optional group the event belongs to.
• data-gtm-label string Optional human readable label for the event.
• data-gtm-value number Optional numeric value associated with the event.
• data-gtm-fields string Optional extra data provided as encoded JSON.

Example:

<button
    data-gtm-on="click"
    data-gtm-event="play"
    data-gtm-category="videos"
    data-gtm-label="Featured Promotional Video"
>
  Play video
</button>
