要获取woocommerce_cart_item_thumbnail挂钩中的选项值

Question

我正在尝试在过滤器挂钩中获取选项值的值。我尝试过以下风声

function custom_cart_item_thumbnail( $thumbnail, $cart_item, $cart_item_key ){
    // // Only for Mini Cart
    // if( is_cart() ) return $thumbnail;

    $product = $cart_item['data'];
    $product_id = $product->get_id();
    $cart_item_count = WC()->cart->get_cart_contents_count();

    $templateId = 9;


    $templateId = get_option( 'current_templateid', true );

    $productId = $cart_item['product_id'];

    // Get the image src
    $image_url = wp_get_attachment_image_src( get_post_thumbnail_id( $productId ), 'single-post-thumbnail' );

    if ( is_multisite() ) { 
        $site = get_current_site();
        $siteID = $site->id;

        $customSrc = 'http://myurl.com?reqmethod=generateProductImage&pid='.$productId.'_'.$siteID.'&productImage='.$image_url[0].'&templateId='.$templateId;
    }
    else {
        $customSrc = 'http://myurl.com?reqmethod=generateProductImage&pid='.$productId.'_0&productImage='.$image_url[0].'&templateId='.$templateId;
    }

    $thumbnail = '<img src="'.$customSrc.'" alt="icon" />';

    return $thumbnail;
}
add_filter( 'woocommerce_cart_item_thumbnail', 'custom_cart_item_thumbnail', 30, 3 );

但是我无法在URL中获得选项值。有任何问题或任何其他方式可以做到这一点。请帮忙。
