I appreciate if i can have some explanations on this string of code:
<?php echo tep_draw_button(IMAGE_BUTTON_CONFIRM_COUPON, 'star', null, 'primary'); ?>
How can i give this button a name, id, value, class etc... ?
How can i give it a OnClcik ?
Its a submit button because of 'null', is it possible to attach to this button a form action ?
