woo-gist.php

// Add to your functions.php file

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->subtotal < $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->subtotal )
                ), '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->subtotal )
                ), 'error' 
            );

        }
    }

}

yes it works.thanks

Awesome stuff, thanks for the help
Just so you know, it causes issues with Braintree, won't allow me to enter my card details.

This method seems to work. Rather than calling the two hooks:

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

Use this instead:
add_action( 'woocommerce_check_cart_items', 'wc_minimum_order_amount' );

It will stop you reaching the checkout unless purchase requirement is met

Quick question:

How do i apply to this to international orders only. E.g. orders from America and canada I want to have it as minimum of 20 items need to be ordered. However for Australia have no minimum requirements?
