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); get_template_part('my-form-template');Now in you template you can then call it.
// Inside my-form-template.php $my_form_id = get_query_var('my_form_id');This is a way to pass variables to the called files.
