# Track UTMs on LearnDash Registration

## UTM attribution overview

HandL UTM Grabber stores campaign data in the browser. This guide shows how to get that data into LearnDash UTM Tracking Integration using hidden fields on your WordPress forms.

### LearnDash UTM Tracking Integration and UTMs

Course sellers want to know which ad drove an enrollment. Capture UTMs on the registration/checkout form.

### Steps

1. Add hidden fields to LearnDash registration or checkout
2. Store in user meta with a small hook on user creation
3. UTM Grabber auto-fills matching field names

### Prefill hidden fields

UTM Grabber fills inputs whose `name` matches a tracked parameter. Field names must line up exactly. List of params: [Native WP Shortcodes](https://docs.utmgrabber.com/books/102-getting-started-for-handl-utm-grabber-v3/page/native-wp-shortcodes).

```
<script>
jQuery(document).ready(function() {
    if (typeof handl_utm === 'undefined') return;
    handl_utm_all_params.forEach(function(param) {
        var val = handl_utm[param] || (typeof Cookies !== 'undefined' ? Cookies.get(param) : '');
        if (val) jQuery('input[name="' + param + '"]').val(val).change();
    });
});
</script>
```
