title: WooCommerce: Add fees to card based on payment gateway selected
body: <p>I need to add a credit card fee % based depending on what payment method the customer selects at the shopping cart in WooCommerce.</p>
  
  <p>This needs to be added to the shopping cart total so that it sends the total amount including the fee to the payment gateway.</p>
  
  <p>For example if the shopping cart total was £100.</p>
  
  <p>If the customer selects 'Credit Card' payment I would like to add 2% to the transaction making the shopping cart total £102. This amount would then go to the external credit card provider for processing as the actually card processing is handled by them (WorldPay_).</p>
  
  <p>I would also like to add a different amount for Paypal 3%.</p>
  
  <p>If the customer selects Cash on Delivery or Bank Transfer I wouldn't add any fees.</p>
  
  <p>There is no WooCommerce plugin that does this. Closest I've got is this thread. </p>
