I have variants in a product page – every property has 2 variants for example
size : 40, 41
color : red, yellow
shape : circle, triangle
when I click on radio inputs I get the indices of the checked inputm for example [0,1,0]
So the question is how to make cartesian indices and then find the index using
$index = array_search($indices, $cartesian);
This is the screen shot of variants:
