php - Wordpress: Add extra fee in cart -

I have created a webshop in Woocommerce (wordpress) It is a liquor store and I need to add an extra cost: 0,08 euros per bottle (product).

I've found it and adjusted it, but I get an additional line in the cart to multiply the number of bottles (0.08) with the price of 0.08, but the value is 0.

Can anyone tell me what I am doing?

  function get_cart_contents_count () {return_filters ('Woocommerce_cart_contents_count', $ this- & gt; cart_account_count); } Function woo_add_cart_fee () {global $ woocommerce; $ Woocommerce- & gt; Cart- & gt; Ad_fe (__ ('custom', 'woocommerce'), $ get_cart_contents_count * 0.08); } Add_action ('woocommerce_cart_calculate_fees', 'woo_add_cart_fee');    
 
 
 Try this code in your functions.php but it will apply to all cartons  
  // Hook before adding fee addition ('woocommerce_cart_calculate_fees', 'add_custom_fees'); Function add_custom_fees (WC_Cart $ cart) {$ charge = 0.08; $ Cart- & gt; Add_f ('handling fee', $ fee); }  
 
  Edit:   To multiply it with each product  
 
  add_action ( 'Woocommerce_cart_calculate_fees', 'add_custom_fees'); Function add_custom_fees (WC_Cart $ cart) {$ fees = 0; Forex Currency ($ Cart-> Get_cart () $ items) {$ charge = $ item ['Quantity'] * 0.08; } If ($ charge! = 0) {$ Cart-> Plus_f ('handling fee', $ fee); }}
