Reply To: Sale banner integration with Woo Discount Rules

Hi Frederik,

These are the two functions that output the standard sale price % discount;

To change either of these functions, you will need to copy the code – making any changes to use your custom discount rules – into the functions.php file of a child theme.

This azuma_before_loop_sale_flash function just adds the start of the theme’s div wrapper, so no need to modify this if you don’t need to change it:

function azuma_before_loop_sale_flash() {
    global $product;
    if ( $product->is_on_sale() ) {
        echo '<div class="sale-flash">';
    }
}

This azuma_after_loop_sale_flash function calculates the discount % and outputs it, so you would need to remove the code that calculates the discount and replace with your own code:

function azuma_after_loop_sale_flash() {
    global $product;
    if ( $product->is_on_sale() ) {
        if ( ! $product->is_type( 'variable' ) && $product->get_regular_price() && $product->get_sale_price() ) {
            $discount_price = $product->get_regular_price() - $product->get_sale_price();
            if ( $discount_price > 0 ) {
                $max_percentage = ( $discount_price  / $product->get_regular_price() ) * 100;
            } else {
                $max_percentage = 0;
            }
        } else {
            $max_percentage = 0;
            foreach ( $product->get_children() as $child_id ) {
                $variation = wc_get_product( $child_id );
                $price = $variation->get_regular_price();
                $sale = $variation->get_sale_price();
                $percentage = '';
                if ( $price != 0 && ! empty( $sale ) ) {
                    $percentage = ( $price - $sale ) / $price * 100;
                }
                if ( $percentage > $max_percentage ) {
                    $max_percentage = $percentage;
                }
            }
        }
        echo '<br /><span class="sale-percentage">-' . esc_attr( round($max_percentage) ) . '%</span>';
        echo '</div>';
    }
}

for example:

function azuma_after_loop_sale_flash() {
    global $product;
    if ( $product->is_on_sale() ) {
        /*
        YOUR CUSTOM CODE TO CALCULATE YOUR DISCOUNT
        */
        echo '<br /><span class="sale-percentage">-' . esc_attr( $your_calculated_discount ) . '%</span>';
        echo '</div>';
    }
}
