[Theming Snippets] Change number of upsells output

wc-change-number-of-upsells.php

/**
 * Change number of upsells output
 */
add_filter( 'woocommerce_upsell_display_args', 'wc_change_number_related_products', 20 );

function wc_change_number_related_products( $args ) {
 
 $args['posts_per_page'] = 1;
 $args['columns'] = 4; //change number of upsells here
 return $args;
}

The filter should be woocommerce_upsell_display_args

Kevin is right. The woocommerce_output_related_products_args will not affect the Upsells on the actual Product page.

Use the woocommerce_upsell_display_args filter instead.

Can we just ban Woo from the internet and save the world from this kind of incompetence? If monkeys had keyboards...

add_filter( 'woocommerce_upsell_display_args', 'custom_woocommerce_upsell_display_args' );	
function custom_woocommerce_upsell_display_args( $args ) {	  
$args['posts_per_page'] = 4; 	  
$args['columns']        = 4; 	  
return $args;	}
