Gravity Forms Data Layer Events for WordPress

A very simple WordPress Plugin to Fire off data layer events for Gravity Forms.

Features

Fires off a Google Tag Manager data layer event gf_form_submission and includes parameters:

• gf_form_id : Form ID in Gravity Forms
• gf_form_name : form name as it exists in Gravity Forms
• emailX : plain text email. If there are multiple email fields on the form it will increment X and add a new key/value for each
• emailX_hashed : SHA-256 hashed version of the email
• gf_total : Form total if form collects $ / is selling a product

Customizable Redirect delay

When using a redirect confirmation, there is a 1 second delay to give time for tags to fire in GTM. if you'd like to delay the submission longer you can add this filter to your theme:

add_filter( 'gfdle_redirect_delay', function() {
    return 1500; // 1.5 seconds
} );

Example dataLayer push

<script>
if(window.self === window.top){
            window.dataLayer = window.dataLayer || [];
            window.dataLayer.push({
                "event": "gf_form_submission",
                "gf_form_id": 2,
                "gf_form_name": "Form Name Here",
                "email": "testing1@builtbyworkhorse.com",
                "email_hashed": "499039d0728c90994ac99e6ea50355450676bd434a11ec6f86d1f5477429b8c2",
                "email2": "testing2@builtbyworkhorse.com",
                "email2_hashed": "ad0f329c326e80765127fd3019336aac74092fc32fe41e435d38f96cfbacc277",
                "gf_total": 10                
            });
        }
</script>

Email Normalization

In addition email addresses are normalized before hashing to ensure accurate matching:

• Converts to lowercase
• Plus addressing removed (myemail+something@domain.com becomes myemail@domain.com)
• Gmail addresses also have dots remove from local part (my.email@gmail.com becomes myemail@gmail.com
