Woocommerce Minimum Order by User Role - php

Question

Somebody previously asked a question similar to mine, but the solutions offered do not seem to help me.
I am working on a wholesale website. For first time buyers, the minimum order is $500. For returning buyers / reorders there is no minimum. I am assuming I need to make 2 different wholesale user roles - one for first time buyers and the other for returning / reorder buyers. I was thinking Wholesale New and Wholesale Reorder would work. How do I apply this to the functions.php? This is the code I am currently using:
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 = 500;
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'
);
}
}
Any help would be greatly appreciated.

Answer 1

You need current_user_can() to test the current user's capability to do something.
Create a Role
First, you would need to create a new role for users who don't have any restrictions. The Members plugin is genius for creating roles and editing their capabilities.
For example, you could create a Returning Wholesaler role.
Define the new Role's capabilities
You should duplicate the "Customer" role's capabilities... so read , edit_posts, and delete_posts.
And then, add a new capability called wholesale_reorder
Modify your conditional logic
Then you can convert your if statement from:
if ( WC()->cart->total < $minimum )
to:
if ( WC()->cart->total < $minimum && ! current_user_can( 'wholesale_reorder' ) )
Simplification in the case of no new roles
If you don't have any existing customers, don't need multiple levels of wholesale, don't have wholesale in conjunction with regular customers, and you don't have a way to register without ordering, then ostensibly you could skip adding new roles and just test current_user_can('customer') as the only people who would be customers would be those who have ordered something already.
