Many people think WooCommerce  coupons are a thing of past – something that old ladies used to clip off newspapers to get a 25-cent discount at the local store. However, as many ecommerce store owners would tell you, coupons are an important source of revenue, simply because of the savings that the shoppers perceive.

However, adding a custom WooCommerce coupon codes is not really a simple process. Although there are several ways in which WooCommerce store owners can add and offer coupons at their store, the method that offers the most control over the entire process of creating and offering is by creating the WooCommerce coupons through code.

This process is straightforward and involves adding WooCommerce coupon code to the functions.php file. At this point, it is important to point out that all the code mentioned in this tutorial should be added to the child theme’s functions.php.

I will start by demonstrating how to create a WooCommerce coupon code. Next, I will show you how to add the discount coupon code, and then I will show the impact of the coupon in action.

Step 1: Add WooCommerce Coupons Code for a Specific Product

To create a coupon with a specific title (I have chosen Cloudways WooCommerce hosting for the purpose of this tutorial), add the following code to the child theme’s functions.php.  Note that after the WooCommerce coupon has been created, it will be automatically applied for specific product IDs.

add_action( 'woocommerce_before_cart', 'cw_coupons_matched' );

function cw_coupons_matched() {

    global $woocommerce;

    $cw_coupon = 'cloudways';

    if ( $woocommerce->cart->has_discount( $cw_coupon ) ) return;

    foreach ( $woocommerce->cart->cart_contents as $key => $values ) {

        $autocoupon = array( 65 );

        if( in_array( $values['product_id'], $autocoupon ) ) {
            $woocommerce->cart->add_discount( $cw_coupon );
            wc_print_notices();
        }
    }
}

In the above snippet, notice the line:

$autocoupon = array( 65 )

This is product ID for which the coupon Cloudways is applied automatically. If you wish to apply the coupon for multiple products, just enter their ID separated by comma in the array.  For your reference, Product ID could be found right under the product name in the All Products listing.

Step 2: Update WooCommerce Coupon Information

Once you have the WooCommerce coupon, the next step is to add it to update the rules and information for the coupon. For this go to the Coupons menu and select the coupon that you have created.

Since I have already created Cloudways, I will update the data for the coupon. The most important items on this page are Discount Type, Coupon Amount, and the Coupon Expiry Date.

You have the option to change the discount type for the product, along with the discounted amount. Since WooCommerce coupons are time-limited, you should be careful in setting up the expiry date to ensure that the coupon expiry matches the duration promised in the marketing campaigns.

Step 3: The WooCommerce Coupon Code in Action

At this point, the coupon (Cloudways in my case) is ready for business.

As you can see from the following screenshot of the cart page, a discount of £10 is automatically applied to the invoice.

Step 4: Apply Content for all Products

There are cases when the store owner wishes to create a coupon that is applicable to all products on the store. Several popular examples include a Holiday Season discount or a store-wide marketing campaign. Here’s how you can create these coupons.

Note: As with all the code mentioned in this tutorial, this will be added to the child theme’s functions.php file.

add_action( 'woocommerce_before_cart', 'cw_coupons_matched' );

function cw_coupons_matched() {
    global $woocommerce;
    $cw_coupon  = 'cloudways';
    if ( $woocommerce->cart->has_discount( $cw_coupon  ) ) return;
    $woocommerce->cart->add_discount( $cw_coupon  );
}

As you can see from the code snippet, the coupon code Cloudways is applicable on all products on the store that accept coupon codes.

Step 5: Create Discount Coupon Through Code

So far you have created the coupon first and then set it’s information through the WooCommerce menu. The good news is that power users could create and set the coupon information through a simple code snippet.

$coupon = array(
    'post_title' => $coupon_code,
    'post_content' => '',
    'post_status' => 'publish',
    'post_author' => 1,
    'post_type'		=> 'shop_coupon'
);

$new_coupon_id = wp_insert_post( $coupon );

As you can see, in the above snippet, I have created a WooCommerce coupon with all the desired parameters, and then inserted it into the list of active coupons.

Generate WooCommerce Coupon through Code

You can easily generate WooCommerce coupon codes through the following snippet. Note that you can either used snippet in a WooCommerce coupon plugin OR as part of the currently activated theme (in the functions.php file)

$coupon_code = 'WooCommerce Coupons'; // Code
$amount = '05';
$discount_type = 'fixed_cart';
$coupon = array(
    'post_title' => $coupon_code,
    'post_content' => '',
    'post_status' => 'publish',
    'post_author' => 1,
    'post_type'		=> 'shop_coupon'
);
$new_coupon_id = wp_insert_post( $coupon );
update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
update_post_meta( $new_coupon_id, 'individual_use', 'no' );
update_post_meta( $new_coupon_id, 'product_ids', '' );
update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
update_post_meta( $new_coupon_id, 'usage_limit', '' );
update_post_meta( $new_coupon_id, 'expiry_date', '' );
update_post_meta( $new_coupon_id, 'free_shipping', 'no' );
