I got an answer from stackoverflow, this works but the all the sizes are being shown in a single button, I want to show all sizes in separate buttons, like the above screenshot has.
I know its possible by adding a loop before echoing my button, my loop is not working
global $product;
if ( $product->is_type('variable') ) {
$taxonomy = 'pa_sizes'; // The product attribute taxonomy
$sizes_array = []; // Initializing
// Loop through available variation Ids for the variable product
foreach( $product->get_children() as $child_id ) {
$variation = wc_get_product( $child_id ); // Get the WC_Product_Variation object
if( $variation->is_purchasable() && $variation->is_in_stock() ) {
$term_name = $variation->get_attribute( $taxonomy );
$sizes_array[$term_name] = $term_name;
}
}
echo '<button class="btn btn-circle btn-lg rounded-circle">' . implode( ', ', $sizes_array ) . '</button>';
}
So, can anybody add a loop just before echoing the button so that I can display all available sizes in different buttons.
