requinix Posted February 12, 2014 Share Posted February 12, 2014 Is it just me or is it that the amount and price vary based on the flavor? Table 1 for the shake by itself, and table 2 for the flavor, amount, and price - and a foreign key to the shake. products id | whatever ---+-------- 1 | shake 1 2 | shake 2 flavors? or maybe product variants? id | amount | price | flavor | product ---+--------+-------+------------+-------- 1 | 500 | 26,50 | banana | 1 2 | 500 | 26,50 | chocolate | 1 3 | 750 | 28,90 | strawberry | 2 4 | 750 | 28,90 | mango | 2 5 | 750 | 28,90 | vanilla | 2 Link to comment https://forums.phpfreaks.com/topic/286140-1-product-multiple-prices-and-flavors/#findComment-1468634 Share on other sites More sharing options...
Psycho Posted February 12, 2014 Share Posted February 12, 2014 I would interpret the "type" of shake as one that has multiple ingredients. So, a pinacolada would have coconut and pineapple. If that is the case, the tables might look more like below. This assumes that each product will have the same sizes available products id | whatever | ---+--------------------- 1 | shake 1 | 2 | shake 2 | ingredients (a list of all possible ingredinets) id | ingredient ---+------------ 1 | banana 2 | chocolate 3 | strawberry 4 | mango 5 | vanilla product_ingredients (which ingredients go with which shake) id | prod_id | ingredient_id ---------------------------- 1 1 1 2 1 2 3 2 3 4 2 4 5 2 5 product_prices (the available sizes for each product and the price) id | prod_id | size | price ---+---------+------+------ 1 | 1 | 500 | 26,50 2 | 2 | 500 | 26,50 3 | 1 | 750 | 28,90 4 | 2 | 750 | 28,90 Link to comment https://forums.phpfreaks.com/topic/286140-1-product-multiple-prices-and-flavors/#findComment-1468647 Share on other sites More sharing options...

Barand Posted February 13, 2014 Share Posted February 13, 2014 That is one way NOT to do it. I'd go with something like this Product +-----+--------------------+ | id | description | +-----+--------------------+ | 1 | Shake | | 2 | Whey protein prof | +-----+--------------------+ | Flavour +---------------------------+ +----+-----------------+ | | id | flavour | Price | +----+-----------------+ +----+---------+------+---------+ | 1 | Banana | | id | prod_id | size | price | | 2 | Chocolate | +----+---------+------+---------+ | 3 | Mango | | 1 | 1 | 500 | 26.50 | | 4 | Strawberry | | 2 | 1 | 750 | 28.90 | | 5 | Vanilla | | 3 | 2 | 920 | 26.50 | +----+-----------------+ | 4 | 2 | 5000 | 115.50 | | +----+---------+------+---------+ | | | +-----------------------------------+ | | | Available | | +----+--------+---------+ | id |price_id| flav_id | +----+--------+---------+ | 1 | 1 | 1 | | 2 | 1 | 2 | | 3 | 2 | 3 | | 4 | 2 | 4 | | 5 | 2 | 5 | | 6 | 3 | 1 | | 7 | 3 | 4 | | 8 | 4 | 2 | | 9 | 4 | 4 | +----+--------+---------+ Link to comment https://forums.phpfreaks.com/topic/286140-1-product-multiple-prices-and-flavors/#findComment-1468722 Share on other sites More sharing options...
piet bieruik Posted February 13, 2014 Author Share Posted February 13, 2014 That looks good, but more scripting. So what will be the sql query. If i wanted to know all the weights with the right flavors of one product?

Barand Posted February 13, 2014 Share Posted February 13, 2014 SELECT p.description , pr.size , GROUP_CONCAT(f.flavour SEPARATOR ', ') as flavours , pr.price FROM product p INNER JOIN price pr ON p.id = pr.prod_id INNER JOIN available a ON pr.id = a.price_id INNER JOIN flavour f ON a.flav_id = f.id GROUP BY p.description, pr.size which should give something like this (no data so not tested) +----------------------+----------+-----------------------------------------+---------+ | description | size | flavours | price | +----------------------+----------+-----------------------------------------+---------+ | Shake | 500 | Banana, Chocolate | 26.50 | | Shake | 750 | Mango, Strawberry, Vanilla | 28.90 | | Whey protein prof | 920 | Banana, Strawberry | 26.50 | | Whey protein prof | 5000 | Chocolate, Strawberry | 115.50 | Link to comment https://forums.phpfreaks.com/topic/286140-1-product-multiple-prices-and-flavors/#findComment-1468735 Share on other sites More sharing options...
