SMNTCS Quantity Increment Buttons for WooCommerce adds minus and plus buttons around the quantity field on the product page and in the classic cart, so customers can change the quantity with one click. The buttons respect the minimum, maximum and step of each product, which makes the plugin work with quantity plugins such as Min/Max Quantities.

Compatible with

• Min and Max Quantity for WooCommerce
• WooCommerce Composite Products
• WooCommerce Min Max Quantity & Step Control Single
• WooCommerce Min/Max Quantities
• WooCommerce Minimum and Maximum Quantity
• WooCommerce Product Bundles

Filters

Add these lines to your theme’s functions.php file or a small plugin.

Swap the order of the buttons to plus, quantity, minus:

add_filter( 'flip_quantity_buttons', '__return_true' );

Turn the buttons off on the product page or on the cart page:

add_filter( 'show_on_product_page', '__return_false' );

add_filter( 'show_on_cart_page', '__return_false' );

Use <button> elements instead of <input type="button">:

add_filter( 'use_html_buttons', '__return_true' );<h3>Contribute</h3>

1. Upload smntcs-quantity-buttons-for-woocommerce to the /wp-content/plugins/ directory.
2. Activate the plugin through the Plugins menu in WordPress.

1. 

   WooCommerce Quantity Buttons on the product page.

2. 

   WooCommerce Quantity Buttons on the cart page.

Where are the settings?

The plugin has no settings page. Activate it and the buttons appear on the product page and in the classic cart. Use the filters described above to change its behaviour.

Does it work with the Cart block?

The Cart and Checkout blocks already have their own plus and minus buttons, so the plugin leaves them alone. It adds its buttons to the product page and to the classic cart.

The quantity changes by 2 instead of 1. What can I do?

Some themes add their own quantity buttons. Since version 2.7 the plugin stops those scripts from changing the quantity a second time. Update to the latest version.

Does it respect minimum, maximum and step values?

Yes. The buttons move in steps and stay between the minimum and maximum. Values that customers type in are rounded to the nearest allowed value, which makes the plugin work with plugins such as Min/Max Quantities.
