title: WooCommerce: Override product info before adding to cart
body: <p>I've found the following example (<a href="https://stackoverflow.com/questions/12327251/woocommerce-add-product-to-cart-with-price-override">WooCommerce: Add product to cart with price override?</a>) which lets the user add a product to the cart. However, it hard codes the prices directly on the cart itself.</p>
  <p>Is there a way to make adjustments to a product instance i.e. costs, append additional user input, etc. and then add the product to the cart?</p>
  <p>Thank you very much for everyones help.</p>

  <p><strong>Edit:</strong></p>
  <p>Having another crack at explaining, as <strong>doublesharp</strong> has pointed out it's not quite clear.</p>
  <p>Joe clicks on a product, he then chooses various options on the product form which then calculates a custom cost after the 'add to cart' button is clicked but before it is added to the cart.</p>
  <p>These options need to be completely custom as the calculations involved are outside of scope of a woocommerce 'variable product'. What I'm trying to achieve is the customer being able to add multiple instances of the same product with various costs and info associated with it.</p>
