To set a minimum order quantity in woocommerce you need to add the following to your theme’s functions.php
Change 50 to whatever amount you want to be the minimum.
/* add a minimum order quantity */ add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' ); add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' ); function wc_minimum_order_amount() { // Set this variable to specify a minimum order value $minimum = 50; if ( WC()->cart->total < $minimum ) { if( is_cart() ) { wc_print_notice( sprintf( 'You must have an order with a minimum of %s to place your order, your current order total is %s.' , wc_price( $minimum ), wc_price( WC()->cart->total ) ), 'error' ); } else { wc_add_notice( sprintf( 'You must have an order with a minimum of %s to place your order, your current order total is %s.' , wc_price( $minimum ), wc_price( WC()->cart->total ) ), 'error' ); } } }
