Display Custom Pricing labels on WooCommerce Cart based on user role

Question

I was just wondering if anyone has a solution for this problem I am currently having. I am actually trying to print a customise price on the shopping cart for my users who are accessing my online store. Below are the conditions which I plan to set.

user who are not logged in -> No Discount, not suppose to see the customise pricing display on my shopping cart page.

user who are logged in as "customer" user role -> No Discount, not suppose to see the customise pricing display on my shopping cart page.

user who are logged in as "paid_customer" user role -> Discount applied, suppose to see the customise pricing display on my shopping cart page.

Currently only users which are not logged in and "paid_customer" user role have their pricing display working correctly but not for "customer" role. Not sure if i am identifying the customer role correctly over here.

Below is the hook which I am using for this condition:

add_filter( 'woocommerce_cart_item_price', function ( $price, $values, $cart_item_key ){

        global $woocommerce;
        $items = $woocommerce->cart->get_cart();
        $user = wp_get_current_user();
    
    if (!is_user_logged_in() || (in_array( 'customer', (array) $user->roles ))){
        
        return $price;
        
    }else{
        
        foreach($items as $item => $values) {
            echo "Discounted Price : " . get_post_meta($values['product_id'] , ('_sale_price', true);       
            return $price;  
        }   
    }

}, 10, 3);

Edit:

My pricing discounts are already managed by Advanced dynamic pricing for WooCommerce plugin, based on my custom user roles, so I don't need to worry about the price output anymore.

See my code answer below, based on @LoicTheAztec accepted answer.

Answer 1

Use this hook instead "woocommerce_before_calculate_totals"

add_action("woocommerce_before_calculate_totals", "set_product_price");

function set_product_price($cart_obj) {
    $user = wp_get_current_user();
    foreach ($cart_obj->get_cart() as $item) {
         if (!is_user_logged_in() || (in_array( 'customer', (array) $user->roles ))){
               $item['data']->set_price(20);
         } else {
               $item['data']->set_price(15);
         }
    }
}

In that way you no need to handle price during checkout and place order process.

Answer 2

This is what I did to accomplish what I wanted (thanks to @LoicTheAztec answer):

add_filter( 'woocommerce_cart_item_price', 'filter_wc_cart_item_price', 10, 3 );

function filter_wc_cart_item_price( $price, $values, $cart_item_key ){

    // For 'lifetime_member' user role when sale price is defined
    if ( current_user_can( 'paid_customer' )) {
    
        echo "Members Price (5% Off): ";

    } elseif (current_user_can('customer')){
        
        echo "Normal Price: ";
        
    } 
    
    return $price;
}

My pricing discounts are already managed by Advanced dynamic pricing for WooCommerce plugin, based on my custom user roles, so I don't need to worry about the price output anymore.

You should mention in your question which plugin you are using, as questions / answers on StackOverFlow are for the hole community and not just for you.

Your code has some mistakes and can be simplified:

add_filter( 'woocommerce_cart_item_price', 'filter_wc_cart_item_price', 10, 3 );
function filter_wc_cart_item_price( $price, $values, $cart_item_key ){

    // For 'paid_customer' user role when sale price is defined
    if ( current_user_can( 'paid_customer' ) && $sale_price = get_post_meta( $values['product_id'],'_sale_price', true) ) {
    
        // The custom formatted sale price
        $price = sprintf( __("Discounted Price : %s"), wc_price( $sale_price ) );
    }
    return $price;
}

It should work.

An edit to your answer code that is incorrect as the data in filter hooks needs always to be returned, but not echoed:

add_filter( 'woocommerce_cart_item_price', 'filter_wc_cart_item_price', 10, 3 );
function filter_wc_cart_item_price( $price, $values, $cart_item_key ){

    // For 'lifetime_member' user role when sale price is defined
    if ( current_user_can( 'paid_customer' ) ) 
    {
        $price = __("Members Price (5% Off): ") .  $price;
    } 
    elseif ( current_user_can('customer') ) 
    {
        $price = __("Normal Price: ") .  $price;
    } 
    return $price;
}

This is the correct and working way.
