How to create a cart function in telegram?

Question

PHP

Good afternoon,
There is a php script that shows products by search in a telegram - pulls data from the database and sends it as a list of products with prices and names.
How can we implement the basket function in this case?
So that you can add products to the cart (for example /plusID /minusID), and then after adding, generate and display a link with all ids.
For example, if you add products with id 1;2;3, then generate a link domain/?add=1&2&3

Answer 1

Use inline buttons. Pass the product id in the callback. Make the basket in the form of a table in the database.
