    One use case for this is to pass variable to template file when calling it with get_template_part().

    // When calling a template with get_template_part()
    set_query_var('my_form_id', 23);

    Now in you template you can then call it.

    // Inside my-form-template.php
    $my_form_id = get_query_var('my_form_id');
