Litle help with pricing in cart
i have a e-shop and i have some quantitative offers for some products.
i want when the customers adds for example the quantity
1 to 4 to the cart, the price of 15 euros,
for 5 to 7 the price of 12 euros,
for 8 to 11 the price of 10 euros
and 12+ the price of 9 euros.
how is this possible? do you have any idea?
this is my SQL query
this quantities and prices are in another table named "quant_prices".
INSERT INTO cart (sessionid,prodID,qty,price VALUES ( '$sesid','$prodID','$qty','$price')
thanks in advance.

Then we need to see that table.

So the "other table" is in fact this one?
Simply fetch the row with the biggest quantity not exceeding the quantity selected by the customer:
ID = ...
AND Quantity <= ...
Given the ID and Quantity, you can now uniquely identify the price (assuming your primary keys are set up correctly).
It might be a good idea to rename that "ID" column into something sensible like "product_id". Otherwise, everybody will think this is an AUTO_INCREMENT column.
