Set a shipping cost per line item in WooCommerce - php

Question

There is the built in option for woocommerce shipping to set a fee for quantity of products in cart. There is also option for fee per shipping class. But I have thousands of products and need to charge a fee for each product(each product not qty of products).
For example 2 product "apples", and 23 product "oranges" in cart. I need to charge flat fee of $10 for any amount of apples and $10 for any amount of oranges. I dont seem to find solution to this in any of the available plugins. They all do fee per quantity but not this.

To get a cost by line item in cart, it requires the following:
1) In WooCommerce Settings > Shipping: set a cost of 10 for your "Flat rate" shipping methods (and save).
2) Add to functions.php file of your active child theme (or active theme), this code:
add_filter( 'woocommerce_package_rates', 'shipping_cost_based_on_number_of_items', 10, 2 );
function shipping_cost_based_on_number_of_items( $rates, $package ) {
$numer_of_items = (int) sizeof($package['contents']);
// Loop through shipping rates
foreach ( $rates as $rate_key => $rate ){
// Targetting "Flat rate" shipping method
if( 'flat_rate' === $rate->method_id ) {
$has_taxes = false;
// Set the new cost
$rates[$rate_key]->cost = $rate->cost * $numer_of_items;
// Taxes rate cost (if enabled)
foreach ($rates[$rate_key]->taxes as $key => $tax){
if( $tax > 0 ){
// New tax calculated cost
$taxes[$key] = $tax * $numer_of_items;
$has_taxes = true;
}
}
// Set new taxes cost
if( $has_taxes )
$rates[$rate_key]->taxes = $taxes;
}
}
return $rates;
}
Refresh the shipping caches: (required)
This code is already saved on your active theme's function.php file.
The cart is empty
In a shipping zone settings, disable / save any shipping method, then enable back / save.
Tested and work.
