WooCommerce: Add to Cart Quantity Plus & Minus Buttons

by adminkys

Here’s a quick snippet you can simply copy/paste to show a “+” and a “-” on each side of the quantity number input on the WooCommerce single product page.

This snippet comes with a jQuery script as well, as we need to detect whether the plus or minus are clicked and consequently update the quantity input. jQuery might look difficult to many, but the beauty of this is that you don’t need to have a degree in jQuery – just copy/paste and see the magic happen.

Note: you will probably also require some custom CSS, as your theme might give a “float” display to the quantity buttons (by default HTML buttons take inline-block).
