Tukukkk

I have a custom post type named products and a taxonomy named product_categories. There are some parent and child terms under product_categories.

I want to add min_price and max_price fields for each term in product page.

With Wordpress's add_post_meta function, I can add minimum and maximum prices as a custom field for each product, but I have no idea how to do relationship between these prices and taxonomy terms.

What should I do for that?

Thanks for your reply Anh, but my problem still continues with add_term_meta function.

For example:

$term_id = '10'; (Kitchen)

add_term_meta ($term_id, 'min_price', '99', true);

In this example, I am adding a minimum price $99 for Kitchen term. But I want to add this price for each posts.

For example:

• Post 1 / Term: Kitchen / Min price: 99


• Post 2 / Term: Kitchen / Min price: 250


• Post 3 / Term: Kitchen / Min price: 320


• Post 4 / Term: Kitchen / Min price: 59

That's exactly what I want to do.

WordPress supports adding meta to taxonomy terms via add_term_meta function. You have to hook to the term edit page, showing the form and use add_term_meta to add meta values.

As there is a lot of work, I'd suggest using a custom fields framework like Meta Box. It supports term meta via MB Term Meta extension.
