disable single variation if user is in specific group - woocommerce

Question

i have a product with 6 variations of Membership (MEMBER, SPECIALMEMBER, NOMEMBER...)
it is possible to enable or disable purchase of this whole product (all variations), if the logged in user is in member group "specialmembers".
if ( user_can( $current_user, "specialmember" )) {
return true;
}
else {
return true;
}
How is it possible to disable just one single variation (MEMBER) für this user group?
Thank you very much for helping a beginner!

Answer 1

By using any one of these hook tags you can disable particular variations.
woocommerce_available_variation
woocommerce_variation_is_active
Solution 1
add_filter(
'woocommerce_available_variation',
function ( $data, $product, $variation ) {
if ( 'green' === strtolower( $variation->get_attribute( 'pa_color' ) ) ) {
$data['variation_is_active'] = false;
}
return $data;
},
10,
3
);
Solution 2
add_filter(
'woocommerce_variation_is_active',
function( $data, $variation ) {
if ( 'green' === strtolower( $variation->get_attribute( 'pa_color' ) ) ) {
return false;
}
return $data;
},
10,
2
);
In both solution we checking if the variation attribute pa_color is green if so then disable that option by assigning false for the variation active property.
As a result that variation will be disabled as represented in the given below image.
