WooCommerce: Change Add to Cart Quantity into a Select Drop-down

by adminkys

The default WooCommerce Add to Cart “Quantity Input” is a simple input field where you can enter the number of items or click on the “+” and “-” to increase/reduce the quantity.

A freelance client hired me to turn that input into a “Select” drop-down. For their audience and UX requirements, it makes sense to let their customers choose the quantity from a drop-down instead of having to manually input the number.

Online there are complex snippets, but I decided to make things easier. The WooCommerce function responsible to generate the quantity input is called “woocommerce_quantity_input“. Luckily, it’s a pluggable function – which means we can simply add this exact same function name to our child theme’s functions.php to completely override it.
