Add tracking pixel / javascript on modal checkout complete | Display Eventbrite

Enable addition javascript to be executed on Eventbrite Modal Order Complete, this can be use for conversion pixels and tracking code

You can aslo use to redirect to a thankyou page but there are some issues
1. EB have a thank you part of teh modal and that disappears a bit quick if you don't add a delay
2. Browsers ask if you want to leave the page which would impact usability - thi can be overridden

This is an example of a redirect with both issues deal with

add_action( 'wfea_popup_scripts_enqueued', function () {
$script = '
window.onbeforeunload = null; // set to null to avoid a message about leaving the page before saved - use if redirecting
wfeaModalCallback = function () {
console.log("There has been an Eventbrite checkout.");

// add your conversion tracking code here or relocation code
// Waits 3 seconds (3000 milliseconds) before redirecting because there is a screen after order complete
setTimeout(function() {
window.location.replace("https://example.com/thank-you-for-registering/");
}, 3000);
// end of tracking code
};';
wp_add_inline_script( 'widget-for-eventbrite-api-eb-popup', $script, 'after' );
} );

This action is available from version 5.5.6 of Display Eventbrite
