Only prompt to set affiliate ID if empty

[bmccarthy]

I am going to be using some functions described in this article to mimic “self-replicating sites” (since I can’t seem to find a wordpress plugin for that). https://support.tipsandtricks-hq.com/forums/topic/manually-setting-the-affiliate-id-and-showing-the-affiliate-id-of-the-referrer

Here’s what I’d like to do.

In my header, I want to display the Affiliate ID, First and Last name, and email address of the affiliate by using [wp_affiliate_referrer_details info=xxxx].

However, if the person landed on our page and wasn’t referred by an affiliate, it want a message (ex: “Affiliate ID required before purchase”) to appear along with the form generated by [wp_aff_set_affiliate_id].

Can you help me out on how to tell WordPress if [wp_affiliate_referrer] is blank, display [wp_aff_set_affiliate_id] instead?

Here is a PHP code example for it:

$referrer = wp_affiliate_get_referrer()

if(empty($referrer)){

echo wp_aff_set_affiliate_id_form();

}
