and how is that a “vague place” anyway? it is specifically written for the wppizza paypal plugin

what are you talking about ?
do you want me to copy and paste what it says in the troubleshooting section ?
i cannot possibly do any of this for you as i have no access to your server nor to your paypal account
once you give me some sort of information as asked there , i might be able to help further

secondly, you have not even provided the most basic info like a link to your site
do you want me to guess what version(s) you are running or plugins you are using ?

furthermore, from what i can see i replied to absolutely all emails (not only yesterday , but going back months and years)
checked your spam folder ? what email did you send it to ? what’s the subject line so i can search for it , in the unlikely case i overlooked this

i cannot see any topics that are in the moderation queue either

you have either not setup IPN or IPN is not working

PS: for the future, please wrap code in code tags here
thanks

that’s got nothing to do with anything

again, what do you get when you add
file_put_contents(‘path/to/some/file.log’, print_r($details_completed, true));
directly at the top of your function you are calling with the on_order_Execute hook

i.e

add_action( 'wppizza_on_order_execute', 'my_order_app', 10, 3);
function my_order_app($order_id, $details_completed, $tid) {
file_put_contents('path/to/some/file.log', print_r($details_completed, true));
}

post the whole data that you receive in this file

doesnt it make more – or at least just as much – sense to simply apply a discount of 10% if pickup across the board ??
