The code in this download folder enables you to set a flat fee shipping rate per product using WooCommerce. The code :
- Adds a custom number field to set your shipping fee on the single product edit screen.
- Outputs a notice before your cart contents encouraging shoppers to increase their orders above the minimum total to receive free shipping.
- Removes other shipping methods when products with custom flat rate shipping fees are added to the cart.
How The Code Works
-
The
custom_shipping_costsfunction is designed to modify WooCommerce shipping rates based on specific conditions. - It calculates the order total, checks if certain products are in the cart, adds a flat rate fee for those products, and offers free shipping for orders over $100.
-
The code uses the
woocommerce_package_ratesfilter to modify shipping rates during the cart/checkout process.
- The code adds a custom text input field named ‘Flat Rate Fee’ to the general product settings in the WooCommerce product editor.
- It saves the entered value as post meta with the key ‘flat_rate_fee’ when the product is saved or updated.
-
The
display_free_shipping_noticefunction is intended to display a cart notice if the order total is below $100 and products with the ‘flat_rate_fee’ custom field are in the cart. - Initially, it checks if any of the specified products are in the cart, then it calculates the order total and displays a notice if conditions are met.
-
The code uses the
loop_startorwoocommerce_before_cart_tableaction hook to insert the notice on the cart page.
- The priority of the action hook determines when the associated function is executed. Lower priority values (e.g., 5) mean the function is executed earlier.
-
In some cases, adjusting the hook priority, as seen in the
add_actionlines, can affect where the notice is displayed.
