Hi, why do we need 2 different methods for storing products in the cart? We have cart->addProduct() and product->addToCart(). Wouldn't it be better if there was only one method to do that?
The tutorial is extremely informative and great, thank you! I have several questions though: 1. In CartItem class, increaseQuantity method, at 14:22 in the video, why aren't we using simply $this->getQuantity() instead of $this->getProduct()->getAvailableQuantity() ? 2. In Cart class, removeProduct method, at 32:50 in the video, why not use just $item->getProduct() instead of using id of a product? 3. I can't really understand how does php match items[$productId] to relevant array element. What is happening when we switch to associative array and how do we actually do that? Would be great if you could advise any resource to understand this point.
1. $this->getQuantity() returns what is the quantity of the item into the cart. However $this->getProduct()->getAvailableQuantity() is what is the available quantity of this product. It total quantity of the product is 5 and initially you added the item with 4 quantity into the cart and then trying to increase the quantity with 2, it will not work because the available quantity is 1. 2. Even though the IDs might be the same the object references might not be the same. That's why comparing IDs is more safe than comparing objects. 3. I think you should read about associative arrays. This might help. th-cam.com/video/yXzWfZ4N4xU/w-d-xo.html
Can someone explain me how does it work : $cartItem2->increaseQuantity(); $cartItem2->increaseQuantity(); I see $cartItem2 is variable which is not an object, right? So how it's possible that we can use here method increaseQuantity() and it works? I have an error when it comes to those lines: Fatal error: Uncaught Error: Call to a member function increaseQuantity() on null in C:\xampp\htdocs\dashboard\serwer\PHPCartOOP-master\index.php:30 Stack trace: #0 {main} thrown in C:\xampp\htdocs\dashboard\serwer\PHPCartOOP-master\index.php on line 30
Didn't watch the video but it could work because he wrote it like this: $cartItem2 = new CartItem(); this will give access to the protected and public methods of the class CartItem in $cartItem2. So he can then write $cartItem2->increaseQuantity()
cartItem2 is an instance of Product class which has access to addToCart() function. Function accepts two attributes. Cart object and quantity. now it can have access to increaseQuantity(). That way it works. OOPs is way complicated than we thnk. lol. correct me if I am wrong.
I've realy waited, after all lessons , oop project.
And here it is, nice!!
Great tutorial!
tip: It would be helpfull if you set View->Appearance->Description of Actions: ON, so we can see the shortcut keys you use.

How can I do, if i want to do this and connect it with my data base?
Keep it going sir, you are doing and adding good stuff.
may god will increase subscribe and the like
Thank you.
You need to show us a demo at the start of video so we understand code easily
Well done!!! I'ld be happy to see more PHP Projects.
Question: wouldn't it be more correct if the quantity is decreased to 0, to remove the product from the cart instead of throwing an exception?
Thanks good point. Yes, maybe
Thanks for Creating this Video
if decreaseQuantity is < 1 it should remove from cart.
Whats the difference between addPorduct and addToCart methods?
They do the same thing, but addProduct is a method of cart class and addToCart is a method of Product class.
Thank you, Great content.
