WooCommerce: Add a WordPress Customizer Setting

If you’ve taken the ConfigureWoo online course, you’ll know that WooCommerce adds its own “WordPress Customizer” section called “WooCommerce”, indeed. From there you can manage some settings such as the store notice, product images, checkout fields and so on.

What if you want to add your own settings, and let yourself or your client toggle options or type input values, so that this can be applied to your current WooCommerce website? Well, that’s quite doable, so in this post we’ll see how they do it. Enjoy!

If you go to WordPress Dashboard > Appearance > Customize you will see the “WordPress Customizer”. By default, WooCommerce plugin adds its own “WooCommerce” section to the Customizer, and from there you can manage some settings.

PHP Snippet: Add a WordPress Customizer WooCommerce Custom Setting

In this example, we will be adding a checkbox to the “WooCommerce” > “Checkout” WordPress Customizer existing section, which will switch between 2 columns checkout layout (default for some WooCommerce themes such as Storefront, 2021, etc.) and a 1 column checkout layout (already the normal behavior for mobiles, so billing is followed by shipping and finally by order review, but we want here to get the same on desktops as well).

As you can see inside the snippet there are 3 parts:

  1. add_setting(): this WordPress function creates the option
  2. add_control(): this WordPress function controls the option, tells WP it’s a checkbox and in which section should show (woocommerce_checkout in the example below)
  3. conditional CSS: this is CSS that only triggers if the option is enabled (checkbox checked in this case)

add_action( 'wp_head', 'bbloomer_switch_checkout_cols_css' );

function bbloomer_switch_checkout_cols_css() {
	if ( true === wc_string_to_bool( get_option( 'woocommerce_checkout_switch_col_layout', 'yes' ) ) ) {
	<style type="text/css">
		.woocommerce-checkout form .col2-set, .woocommerce-checkout form #order_review, .woocommerce-checkout form #order_review_heading {
			width: 100%;
			float: none;
			clear: none;
			padding-left: 0;
			padding-right: 0;

Before & After Screenshots

Before: on desktop my theme shows a 2 columns checkout.
After: once my custom setting (a checkbox) is checked, my checkout layout on desktop goes onto 1 column.

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.
