WooCommerce: Checkbox to Disable Related Products Conditionally

Here’s how you can display a “checkbox” in the product edit page in order to hide the Related Products section in case this is checked. This is something you can also reuse to hide other sections in the same way – for example you might need to hide product tabs or featured image in certain cases.

I’ve coded this in 15 minutes for a client so why not sharing it with you too? Here’s the full snippet, enjoy!

PHP Snippet: Hide Related Products on a Per-Product Basis

// -----------------------------------------
// 1. Add new checkbox product edit page
 
add_action( 'woocommerce_product_options_general_product_data', 'bbloomer_add_related_checkbox_products' );        
 
function bbloomer_add_related_checkbox_products() {           
   woocommerce_wp_checkbox( array( 
      'id' => 'hide_related', 
      'class' => '', 
      'label' => 'Hide Related Products'
   ));      
}
 
// -----------------------------------------
// 2. Save checkbox into custom field
 
add_action( 'save_post_product', 'bbloomer_save_related_checkbox_products' );
 
function bbloomer_save_related_checkbox_products( $product_id ) {
	global $pagenow, $typenow;
	if ( 'post.php' !== $pagenow || 'product' !== $typenow ) return;
   if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
   if ( isset( $_POST['hide_related'] ) ) {
      update_post_meta( $product_id, 'hide_related', $_POST['hide_related'] );
   } else delete_post_meta( $product_id, 'hide_related' );
}
 
// -----------------------------------------
// 3. Hide related products @ single product page
 
add_action( 'woocommerce_after_single_product_summary', 'bbloomer_hide_related_checkbox_products', 1 );
 
function bbloomer_hide_related_checkbox_products() {
   global $product;
   if ( ! empty ( get_post_meta( $product->get_id(), 'hide_related', true ) ) ) {
      remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20 );
   }
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
