For example
array (
product1_quantity => 5,
product1_quantity => 1,
product2_quantity => 3,
product2_quantity => 7,
product3_quantity => 2,
)
with result:
product1_quantity - 6,
product2_quantity - 10,
product3_quantity - 2
Thanx!
sorry, guys
stupid example, instead this really
Array ( [0] => Array ( [product1] => 7 ) [1] => Array ( [product1] => 2 ) [2] => Array ( [product2] => 3 ) )
?
