Add Coupon Exclusion By Attribute

You can’t exclude just an attribute. However, if you configure your products as variable products (https://docs.woocommerce.com/document/variable-product/) based on those attributes, you can exclude specific variations (say a red version of a t-shirt) from a coupon just like you would a normal product.

All my products are variable products, but I have ALOT of variations so there are like 10 different priced variations with the color black for each product.

I was hoping to duplicate the coupon category exclude and switch for attributes in the class-wc-meta-box-coupon-data.php.

Is that possible?

// Exclude Categories
?>
<p class=”form-field”><label for=”exclude_product_categories”><?php _e( ‘Exclude categories’, ‘woocommerce’ ); ?></label>
<select id=”exclude_product_categories” name=”exclude_product_categories[]” style=”width: 50%;” class=”wc-enhanced-select” multiple=”multiple” data-placeholder=”<?php esc_attr_e( ‘No categories’, ‘woocommerce’ ); ?>”>
<?php
$category_ids = $coupon->get_excluded_product_categories();
$categories = get_terms( ‘product_cat’, ‘orderby=name&hide_empty=0’ );

if ( $categories ) {
foreach ( $categories as $cat ) {
echo ‘<option value=”‘ . esc_attr( $cat->term_id ) . ‘”‘ . selected( in_array( $cat->term_id, $category_ids ), true, false ) . ‘>’ . esc_html( $cat->name ) . ‘</option>’;
}
}
?>
</select> <?php echo wc_help_tip( __( ‘Product categories that the coupon will not be applied to, or that cannot be in the cart in order for the “Fixed cart discount” to be applied.’, ‘woocommerce’ ) ); ?></p>
<?php

echo ‘</div><div class=”options_group”>’;

Then add below to class-wc-coupon.php but for the attributes created above.

// Exclude Categories
?>
<p class=”form-field”><label for=”exclude_product_categories”><?php _e( ‘Exclude categories’, ‘woocommerce’ ); ?></label>
<select id=”exclude_product_categories” name=”exclude_product_categories[]” style=”width: 50%;” class=”wc-enhanced-select” multiple=”multiple” data-placeholder=”<?php esc_attr_e( ‘No categories’, ‘woocommerce’ ); ?>”>
<?php
$category_ids = $coupon->get_excluded_product_categories();
$categories = get_terms( ‘product_cat’, ‘orderby=name&hide_empty=0’ );

if ( $categories ) {
foreach ( $categories as $cat ) {
echo ‘<option value=”‘ . esc_attr( $cat->term_id ) . ‘”‘ . selected( in_array( $cat->term_id, $category_ids ), true, false ) . ‘>’ . esc_html( $cat->name ) . ‘</option>’;
}
}
?>
</select> <?php echo wc_help_tip( __( ‘Product categories that the coupon will not be applied to, or that cannot be in the cart in order for the “Fixed cart discount” to be applied.’, ‘woocommerce’ ) ); ?></p>
<?php

echo ‘</div><div class=”options_group”>’;
