Add a custom fee from an attribute

    Hey!

    I live in norway, and our site sells batteries. We are obligated by the state to add a lead-fee. Lets say it’s 0,2$ per aH.

    Example: for a 12ah battery, the fee will be (0,2 * 12) 2,4$

    I don’t know how to add this fee. Every turtorial I find usually have a fixed or a % fee. But this fee needs to be custom for each battery.

    I have this code that adds a fee from the weight, but i don’t know how to make it gather how many “aH” the battery has.

    function shipping_weight_fee( $cart ) {
			if ( is_admin() && ! defined( 'DOING_AJAX' ) )
				return;

			/* SETTINGS */

			// Specific categories
			$specific_categories = array( 'battery', 'batteries' );

			// Initial fee
			$fee = 0.60;

			/* END SETTINGS */

			// Set variable
			$total_weight = 0;

			// Loop though each cart item
			foreach ( $cart->get_cart() as $cart_item ) {
				// Get product id
				$product_id = $cart_item['product_id'];

				// Get weight
				$product_weight = $cart_item['data']->get_weight();

				// NOT empty & has certain category     
				if ( ! empty( $product_weight ) && has_term( $specific_categories, 'product_cat', $product_id ) ) {
					// Quantity
					$product_quantity = $cart_item['quantity'];

					// Add to total
					$total_weight += $product_weight * $product_quantity;
				}
			}

			if ( $total_weight > 0 ) {          
				$cart->add_fee( __( 'Lead fee' ), $fee * $total_weight, false );      
			}
		}
		add_action( 'woocommerce_cart_calculate_fees', 'shipping_weight_fee', 10, 1 );

    Hi @an29

    Would it not be easier setting the ah values up as attributes, all the way from the lowest to highest value, then using something like https://wordpress.org/plugins/markup-by-attribute-for-woocommerce/ to add the markup on each attribute?

    Cheers!

    Yes the ah value is set up in the attribute. I’d want to make a similar code to the one i’ve already created. Only this get the ah value. I don’t know how to get the ah value. I used this $product_weight = $cart_item[‘data’]->get_weight(); to get the weight. Is there a simular way to get a value from the attribute?

    This is for simple products. It don’t have product variations.

    You could try using something like the following to get attributes.

    $ah_values = get_the_terms( $product->id, 'pa_ah');

    You could also consider using a plugin like https://iconicwp.com/products/woocommerce-attribute-swatches/ to add that.

    Cheers!

    Thanks!

    Could you see if you see anything wrong with this code?

    function shipping_weight_and_lead_fee( $cart ) {
			if ( is_admin() && ! defined( 'DOING_AJAX' ) )
				return;

			/* SETTINGS */

			// Specific categories
			$specific_categories = array('Startbatterier', 'Buffalo Bull SHD', 'Li-ion MC batterier', 'NG – Gel Batterier', 'NH - Høyrate Batterier', 'NF – Frontmonterte Batterier', 'NM - 10års Batterier','NS - 5års Batterier', 'Running Bull', 'Power Bull PRO', 'Buffalo Bull', 'Starting Bull', 'Buffalo Bull SHD Pro', 'Power Bull', 'Bike Bull Classic 6V', 'Bike Bull Classic 12V', 'Bike Bull AGM 12V', 'Bike Bull GEL 12V', 'Bike Bull AGM PRO 12V', 'Freshpack', 'AGM', 'GEL');

			// Initial fee
			$fee = 0.60;
			$feeah = 2.00;

			/* END SETTINGS */

			// Set variable
			$total_weight = 0;
			$total_ah = 0;

			// Loop though each cart item
			foreach ( $cart->get_cart() as $cart_item ) {
				// Get product id
				$product_id = $cart_item['product_id'];

				// Get weight
				$product_weight = $cart_item['data']->get_weight();
				$ah_values = get_the_terms( $product->id, 'ah');

				// NOT empty & has certain category     
				if ( ! empty( $product_weight ) && has_term( $specific_categories, 'product_cat', $product_id ) ) {
					// Quantity
					$product_quantity = $cart_item['quantity'];

					// Add to total
					$total_weight += $product_weight * $product_quantity;
				}
				if ( ! empty( $ah_values ) && has_term( $specific_categories, 'product_cat', $product_id ) ) {
					// Quantity
					$product_quantity = $cart_item['quantity'];
					$total_ah += $ah_values * $product_quantity;
				}
			}

			if ( $total_weight > 0 ) {          
				$cart->add_fee( __( 'Miljøtillegg' ), $fee * $total_weight, false );  
				$cart->add_fee( __( 'Blytillegg' ), $feeah * $total_ah, false ); 
			}

		}
		add_action( 'woocommerce_cart_calculate_fees', 'shipping_weight_and_lead_fee', 10, 1 );

    Hi there,

    This is a fairly complex development topic. I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.

    I can also recommend the WooCommerce Developer Resources Portal for resources on developing for WooCommerce.

    You can also visit the WooCommerce Facebook group or the #developers channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, as well.

    Best,

    Little update;

    I think my problem lays here

    // Get weight & attribute values
$product_weight = $cart_item['data']->get_weight();
$ah_values = get_the_terms( $product->id, 'pa_ah');

    If i duplicate the $cart_item['data'], I get the white screen of death somehow.. Is there maybe another line of code that gets the values from the AH attribute?

    I guess the $cart_item['data'] gathers all the info from the products in the cart. And it only picks out the weight.. Is it possible to use a function to get both the attribute value and the weight and assign them to $product_weight and $ah_values

    Hi @an29

    Thanks for the update, but as we explained before, support for custom coding is beyond the scope of support we are able to provide in this forum. This particular forum is for questions that are related to the WooCommerce core features.

    You can get useful inputs and insights by posting your query in the development related channels instead, that we shared above.

    Hoping for a quick resolution.

    Cheers
