Wordpress + Woocommerce: hide unavailable variations when there are 2 attributes

问题

I have a variable product in WordPress + WooCommerce and it has 2 attributes: color and size.

I'd like that when I select one of these 2 attributes, the unavailable variations with the second attribute will be automatically hidden (or unselectable) from the attribute select menu.

Is it possible? How can I achieve that?

I haven't found any plugin that can do that. I'm trying to figure out what part of code to edit, but it's quite a difficult task...

回答1:

I ran into your (old) question as i had it too. This is a working solution. Change 'return 10' to a number higher than your total amount of variations.

Add it to your function.php file:

function custom_wc_ajax_variation_threshold( $qty, $product ) {
    return 10;
}

add_filter( 'woocommerce_ajax_variation_threshold', 'custom_wc_ajax_variation_threshold', 10, 2 );
