Weekly access based on coupon

We use S2members for our newspaper’s website, which gives paid members (subscribers) bonus content in addition to a ton of free content.
I would like to have a password of the week (coupon/free trial) that someone could enter for complete access. The user would not need any registration, just the secrete word of the week that we would publish in our newspaper (we still want people to buy a newspaper).
I understand conceptually how this could work (enter code word, cookie placed on user, access unveiled) but I can’t find anywhere in S2 that explains this type of coupon use.
Can S2 work without someone registering or logging in?
This would work in concert to our typical online subscribers that pay for access using S2.
And I truly searched hard for this answer to no avail.

BTW: the relevant topics that popped up based on my subject line in this thread is a great idea. Very cool.

Thanks for your inquiry. ~ We appreciate your patience :-)

Right. s2Member’s Coupon Codes are designed to provide discounts on purchases, but not to discount things all the way down to a completely free scenario, unfortunately. This may come in a future release.

For now, the easiest way to handle this, is by setting up a Pro Form for Free Registration, and wrapping it with Simple Conditionals that would test for the existence of a Coupon Code (or Codes) that you generate yourself and integrate into this scenario.

Raam (an s2Member® Support Rep) put together a how-to article covering this topic here.

It may also be worth your time to read this recent KB article that goes into more detail about Simple Shortcode Conditionals. See: Knowledge Base » Simple Shortcode Conditionals

So let’s assume for a moment that you have a cookie set in the customer’s browser with the Coupon Code that makes it possible for them to register at no cost. I’ll assume you’re dealing with this part in custom code.

Now you will create a WordPress® Post or Page and pop a Free Registration Form Shortcode into it.

<?php if(!empty($_COOKIE&#91;'coupon_code'&#93;) && $_COOKIE&#91;'coupon_code'&#93; === 'FREEREG2013'){ ?>

	[s2Member-Pro-PayPal-Form register="1" level="0" /]
	
<?php } else { ?>
	Sorry, your Coupon Code has expired.
<?php } ?>
