Check affiliate URL format and output based on AffiliateWP settings

[nutsandbolts]

AffiliateWP allows customization of the affiliate URLs via Affiliates > Settings > Referral Settings. The URL may contain something other than /ref/ (the site owner enters what they want) and can have the user ID or username OR a custom slug at the end if they are using the Custom Affiliate Slugs addon.

We need to check what format is being used and output our affiliate links in the same format to avoid confusion. For example, if Bob Smith's affiliate link is blah.com/go/bobsmith/ and we are outputting it as blah.com/ref/123/ he may think his referrals aren't tracking correctly.

Yes, this is true.

We also need to account for pretty URLs. Right now the addon only works with query paramters. But some sites use the pretty path like you mention. https://example.com/my-post/ref/[email protected].

We need to hook into AffiliateWP or use one of their functions to get the setting and filter the URL accordingly.
