Applying global or sitewide discounts using customer-specific pricing

• It is possible to add global user, role & group based pricing rules which are applicable to all the products on your WooCommerce store.
• Adding individual rules for all the products will be time-consuming.
• Hence, it will be useful for the admins managing large web stores.
• It is possible with the help of the following filters.
  • “wdm_csp_filter_usp_rules_for_a_product”.
  • “wdm_csp_filter_rsp_rules_for_a_product”.
  • “wdm_csp_filter_gsp_rules_for_a_product”.
• Priorities for these rules will work the same as the default priorities in CSP.

Adding a user-specific global discount

• The following code will explain how you can apply global discounts for your site users.

add_filter('wdm_csp_filter_usp_rules_for_a_product', 'applyUSPglobalDiscounts', 99, 3);

function applyUSPglobalDiscounts( $uspRules, $user, $productIds) {
    //get global discount value for the user
    $discountValue    =    10; //Replace this line with your logic to get the discount value for the user
    if (empty($discountValue)) {
        return $uspRules;
    }
    if (is_array($productIds)) {
		//Variable product variations
        foreach ($productIds as $productId) {
            $temp                = new \stdClass();
            $temp->price        = $discountValue;
            $temp->min_qty        = 1;
            $temp->flat_or_discount_price    = 2;
            $temp->product_id    = $productId;
            $uspRules[] = $temp;
        }
    } else {
		//Simple products
        $temp                = new \stdClass();
        $temp->price        = $discountValue;
        $temp->min_qty        = 1;
        $temp->price_type    = 2;
        $temp->product_id    = $productIds;
        $uspRules[] = $temp;
    }
    return $uspRules;
}

• Adding the above code in your child themes functions.php file will allow a 10% sitewide discount for all users because of the code on Line #5.

Adding a role-specific global discount

• The following code will explain how you can apply global discounts for the user roles on your site.

add_filter('wdm_csp_filter_rsp_rules_for_a_product', 'applyRSPglobalDiscounts', 99, 3);

function applyRSPglobalDiscounts( $rspRules, $userRoles, $productIds) {
    //TODO: add your logic to get the discount value for all the user roles & pick the value which will give the most discount
    $discountValue    =    10;
    if (empty($discountValue)) {
        return $rspRules;
    }
    if (is_array($productIds)) {
        foreach ($productIds as $productId) {
            $temp                = new \stdClass();
            $temp->price        = $discountValue;
            $temp->min_qty        = 1;
            $temp->flat_or_discount_price    = 2;
            $temp->product_id    = $productId;
            $rspRules[] = $temp;
        }
    } else {
        $temp                = new \stdClass();
        $temp->price        = $discountValue;
        $temp->min_qty        = 1;
        $temp->price_type    = 2;
        $temp->product_id    = $productIds;
        $rspRules[] = $temp;
    }
    return $rspRules;
}

• Adding the above code in your child themes functions.php file will allow a 10% sitewide discount for all user roles because of the code on Line #5.

Adding a group-specific global discount

• The following code will explain how you can apply global discounts for the user groups on your site.

add_filter('wdm_csp_filter_gsp_rules_for_a_product', 'applyGSPglobalDiscounts', 99, 3);
function applyGSPglobalDiscounts( $gspRules, $userGroups, $productIds) {
    //get globalCSP discount values for the group or for the defined groups
    //TODO: get the discount value for all the user groups & pick the value which will give the most discount
    $discountValue    =    10;
    if (empty($discountValue)) {
        return $gspRules;
    }
    if (is_array($productIds)) {
        foreach ($productIds as $productId) {
            $temp                = new \stdClass();
            $temp->price        = $discountValue;
            $temp->min_qty        = 1;
            $temp->flat_or_discount_price    = 2;
            $temp->product_id    = $productId;
            $gspRules[] = $temp;
        }
    } else {
        $temp                = new \stdClass();
        $temp->price        = $discountValue;
        $temp->min_qty        = 1;
        $temp->price_type    = 2;
        $temp->product_id    = $productIds;
        $gspRules[] = $temp;
    }
    return $gspRules;
}
