Were do we leave this exactly, the code or file. When my users subscribe by check, and get email, i want them to get this too. A attachment. Waiting ages get help from premium support . Thanks

This may be added to your PMPro Customizations Plugin - https://www.paidmembershipspro.com/create-a-plugin-for-pmpro-customizations/

any other attachment will be deleted if you use above code, you can change like this:

change this:

if(is_array($attachments))

into this:
if(!is_array($attachments))

so it wont delete your other attachments
