The process of modifying the cart's price and quantity exclusively through MVC, without utilizing ajax or livewire would involve the following steps:
- Create a controller method that receives the updated price and quantity values from a form submission or user input.
- In the controller method, update the cart model with the new price and quantity values.
- Redirect the user back to the cart view, which will display the updated cart with the modified price and quantity values.
- In the cart view, update the HTML and/or PHP code to display the modified price and quantity values retrieved from the cart model.
- When the user submits an order or clicks a checkout button, the MVC framework should carry out the appropriate business logic to finalize the order.
Note that this process assumes that the MVC framework being used includes built-in support for session management and handling form submissions. If not, this functionality will need to be implemented separately, either through a custom MVC plugin or through third-party libraries.
