I am building an website for displaying products. I have the custom post type "products" and this post has many custom fields, one is a checkbox with only one possible choice. This checkbox is there to allow the product to display in front page as a featured product. I need to have only one product with that checkbox checked. To prevent that more than one hava that checkbox checked is there a way to when we check that checkbox field, uncheck the same checkbox field in the others products?
I hope that i made myself clear.
Thanks in advance!
