Show units sold as word on WooCommerce Archive and Product Page

I am trying to understand how to show single and multiple values for my count.

Basically like this:

  • "Bought by one customer so far" opposite "Bought by 1 customer so far"
  • "Bought by five customers so far" opposite "Bought by 5 customers so far"

How can I convert the total sales number to a word/string?

This is the code I am working with:

add_action( 'woocommerce_single_product_summary', 'product_sold_count', 11 );
add_action( 'woocommerce_after_shop_loop_item', 'product_sold_count', 11 );
function product_sold_count() {
    global $product;
    $units_sold = get_post_meta( $product->get_id(), 'total_sales', true );
    if ($units_sold) echo '<span class="bought-by-customers">' . sprintf( __( 'Bought by %s customers so far', 'woocommerce' ), $units_sold ) . '</span>';
}

Which works, but not the way I prefer it. Any advice?

For your question you can use the PHP NumberFormatter class,

You can also use WC_Product::get_total_sales() versus get_post_meta()

So you get:

function product_sold_count() {
    global $product;
    
    // Is a WC product
    if ( is_a( $product, 'WC_Product' ) ) {
        // Get total sales
        $units_sold = $product->get_total_sales();
        
        if ( $units_sold >= 1 ) {
            // https://www.php.net/manual/en/class.numberformatter.php
            $fmt = new NumberFormatter( 'en', NumberFormatter::SPELLOUT );
            
            // Singular are plural
            $units_sold == 1 ? $s_p = '' : $s_p = 's';
        
            // Output
            echo '<span class="bought-by-customers">' . sprintf( __( 'Bought by %s customer%s so far', 'woocommerce' ), $fmt->format( $units_sold ), $s_p ) . '</span>';
        }
    }
}
add_action( 'woocommerce_single_product_summary', 'product_sold_count', 11 );
add_action( 'woocommerce_after_shop_loop_item', 'product_sold_count', 11 );

Result:

  • Bought by thirty-one customers so far
  • Bought by one customer so far
