I have made a multiple category. Each item belong to one or more category. So when display one item, i like to retreive the category of this item, and display all post that have belong to that category.
Example. Chair : cat = sit, leather, one person
So when display the chair, i like below to display all item that have : sit leather and one person as category
Is there a plugsin that do that ?, or in php it's simple to do ?
