隐藏WooCommerce目录中具有特定库存状态的所有产品

我在Wordpress和Woocommerce网站上使用Flatsome模板。我还创建自定义库存状态（例如noproduzione，当不再从制造商创建产品时使用）。但是我不想noproduzione在我的网站上显示此产品（库存状态）（仅在管理页面中）。

我正在使用我在此处编写的代码（将其放在我的functions.php文件中），但似乎在Flatsome上不起作用。如何将其应用于此模板？

add_action( 'woocommerce_product_query', 'qc_action_product_query', 10, 2 );
function qc_action_product_query( $q, $query ) {

    // Get any existing meta query
    $meta_query = $q->get( 'meta_query');
    
    // Define an additional meta query 
    $q->set( 'meta_query', array( array(
        'key'     => '_stock_status',
        'value'   => 'noproduzione',
        'compare' => 'NOT LIKE',
    ) ) );
    
    // Set the new merged meta query
    $q->set( 'meta_query', $meta_query );
}

为了创建自定义代码，我使用了StackOverflow上的一些代码

// Add new stock status options
add_filter( 'woocommerce_product_stock_status_options', 'filter_woocommerce_product_stock_status_options', 10, 1 );
function filter_woocommerce_product_stock_status_options( $status ) {
    // Add new statuses
    $status['10days'] = __( 'Disponibile entro 10 giorni', 'woocommerce' );
    $status['inarrivo'] = __( 'In arrivo', 'woocommerce' );
    $status['noproduzione'] = __( 'Fuori produzione', 'woocommerce' );

    return $status;
}
                  
// Availability text
add_filter( 'woocommerce_get_availability_text', 'filter_woocommerce_get_availability_text', 10, 2 );
function filter_woocommerce_get_availability_text( $availability, $product) {
    switch( $product->get_stock_status() ) {
        case '10days':
            $availability = __( 'Disponibile entro 10 giorni', 'woocommerce' );
        break;
        case 'inarrivo':
            $availability = __( 'In arrivo', 'woocommerce' ); 
        break;
    case 'noproduzione': 
    $availability = __( 'Fuori produzione', 'woocommerce' );  
    
        break;
    }
    return $availability;  
}

我添加了代码以显示可用性文本，并在产品为noproduzione库存状态时隐藏购物车按钮

// Display the stock status on other page
add_action( 'woocommerce_after_shop_loop_item_title', 'wcs_stock_text_shop_page', 25 );
function wcs_stock_text_shop_page() {
    //returns an array with 2 items availability and class for CSS
    global $product;

    $availability = $product->get_stock_status();
    //check if availability in the array = string 'noproduzione'
    //if so display on page.//if you want to display the 'in stock' messages as well just leave out this, == 'Out of stock'
    if ( $product->get_stock_status() === 'noproduzione') {
        echo '<span style="color:#b20000;">Fuori produzione!</span>';
    }
    else if ( $product->get_stock_status() === 'onbackorder') {
        echo '<span style="color:#13b200;">Disponibile su ordinazione</span>';
    }
    else if ( $product->get_stock_status() === '10days') {
        echo '<span style="color:#13b200;">Disponibile in 10 giorni</span>';
    }
    else if ( $product->get_stock_status() === 'inarrivo') {
        echo '<span style="color:#e0c81d;">In arrivo</span>';
    }
    else if ( $product->get_stock_status() === 'outofstock') {
        echo '<span style="color:#b20000;">Terminato!</span>';
    }
    else {
        echo '<span style="color:#53af00;">Disponibile!</span>';
    }
}

// Hide the cart button if stock status is 'noproduzione'
add_filter('woocommerce_is_purchasable', 'filter_is_purchasable_callback', 10, 2 );
add_filter('woocommerce_variation_is_purchasable', 'filter_is_purchasable_callback', 10, 2 );
function filter_is_purchasable_callback( $purchasable, $product ) {
    if ( $product->get_stock_status() === 'noproduzione' ) { 
        return false;
    }
    return $purchasable;
}

最后，我还添加了此代码，这很有用，因为按“库存”状态订购“相关产品”，对我来说是好的，因为不显示其他自定义库存状态。但是我想将此应用到我的所有前端站点。

//show, in the related products, only instock products!
add_filter( 'woocommerce_related_products', 'filter_woocommerce_related_products', 10, 3 );
function filter_woocommerce_related_products( $related_posts, $product_id, $args ) {    
    foreach( $related_posts as $key => $related_post ) {        
        // Get product
        $related_product = wc_get_product( $related_post );
        
        // Is a WC product 
        if ( is_a( $related_product, 'WC_Product' ) ) {
            // Stock status
            $stock_status = $related_product->get_stock_status();
            
            // NOT instock
            if ( $stock_status != 'instock' ) {
                unset( $related_posts[$key] );
            }
        }
    }
    
    return $related_posts;
}

因此，问题是：如何在我的网站上隐藏此产品（Noproduzione库存状态）（并仅在管理页面中显示）？Noproduzione与OUTOFSTOCK不同！
