JS / PHP for Shop Cart Count (WP)

It’s been a while since I’ve been here. There once was some OG coders that roamed these forums with custom sites but I can’t seem to locate them anymore. I’m looking to add a cart count button to my site instead of just a cart button. Running WP but can hard code it into the template if anyone has this working or can guide me in the right direction. https://nekkidtees.com
