Hide username field when a coupon is apply

Good morning,

I newly installed S2member on my website (with pro-form) and I then wanted to make sure that the username is replaced with address email of the user.

I followed the procedure found on the forum (http://www.s2member.com/forum/topic/make-username-field-optional-and-hide-it/) and also read this post : http://www.primothemes.com/forum/viewtopic.php?F=4*t=15672*p=49082*p49082

Everything works perfectly but I have a small bug when I speed up coupons on forms. When the coupon is applied, the field ‘username’ is not any more hidden while it was not shown in the load of it page.

Would anybody have an idea to make it hidden again?

Thank you for your answer.
Nicolas

Hello,

Please change this line:

if(empty ($_POST["s2member_pro_paypal_checkout"]) && empty($vars["attr"]["modify"])) {

to this:

if(empty($vars["attr"]["modify"])) {
