WordPress Speed Up Service | WordPress Website Maintenance Packages Hi and thanks for reading. •In each post I have a div, id="buy_info". Inline style for div, display: initial. PayPal buy now button resides in div. •I dynamically send post_id as item_id to PayPal in button parameters. When PayPal Instant Payment Notification is recieved with item_id, say "200", I want the CSS display style, for the buy_info div, in post_id 200, changed to "none". I know I can make the CSS display value conditional upon the value of the IPN item_id that was recieved but how? Thanks!
