CoCart Lite v3.1 Release Candidate 4

This last release candidate got delayed but one I think was worth the wait. I’m excited to announce that CoCart Lite v3.1 Release Candidate 4 is now available for testing! You can either download it directly from GitHub or install the CoCart Beta Tester plugin.

This release applies a few adjustments but more importantly I added a feature last minute, again, that users have been wanting and that is to set the price of an item as it’s being added to the cart.

A few new filters have also been introduced to help extend CoCart further should you need it.

See below for more details.

For a full recap on what’s new in v3.1 see the following previous posts before continuing:

Set Price While Adding to Cart

This particular function is something that is normally programmed based on conditions that allows you to override the set price with the help of using WooCommerce’s action hook woocommerce_before_calculate_totals.

The only possible option that was available at the time was for the store to have a WooCommerce extension called “Name Your Price” installed and pass the price via item data.

curl -X POST https://example.com/wp-json/cocart/v2/cart/add-item \
  -H "Content-Type: application/json" \
  -d '{
    "id": "129",
    "quantity": "1",
    "item_data": {
      "nyp": 24
    }
  }'

However, that was more specific to validating the customers inputted price when adding any product to the cart that enabled the feature.

Now you can set the price how you like without any additional requirements using the new price parameter.

curl -X POST https://example.com/wp-json/cocart/v2/cart/add-item \
  -H "Content-Type: application/json" \
  -d '{
    "id": "129",
    "quantity": "1",
    "price": 24
  }'

To achieve this supported feature, a new cache system had to be created that would store a copy of the modified version of the item in session.

This is then used to set the new price before the totals are calculated.

That’s it. As long as that item is in the cart with the custom price, the sub-total will calculate based on that.

If the item is removed from the cart and is added again without the custom price, the original price will be used.
