# Track UTMs on Tutor LMS Registration

## UTM attribution overview

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

### Tutor LMS UTM Tracking Integration and UTMs

Course registration attribution via hidden fields.

### Steps

1. Add fields to registration or checkout template

### 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>
```
