Question

当产品变化缺货时，我希望在变体旁边显示“缺货”。下面，我使用的是this answer代码：

add_filter( 'woocommerce_variation_option_name', 
'customizing_variations_terms_name', 10, 1 );
function customizing_variations_terms_name( $term_name ){

if(is_admin())
    return $term_name;

global $product;
$second_loop_stoped = false;

// Get available product variations
$product_variations = $product->get_available_variations();

// Iterating through each available product variation
foreach($product_variations as $variation){

    $variation_id = $variation['variation_id'];
    $variation_obj = new WC_Product_Variation( $variation_id );

    ## WOOCOMMERCE RETRO COMPATIBILITY ##
    if ( version_compare( WC_VERSION, '3.0', '<' ) ) # BEFORE Version 3 (older)
    {
        $stock_status = $variation_obj->stock_status;
        $stock_qty = intval($variation_obj->stock);

        // The attributes WC slug key and slug value for this variation
        $attributes_arr = $variation_obj->get_variation_attributes();
    }
    else # For newest verions: 3.0+ (and Up)
    {
        $stock_status = $variation_obj->get_stock_status();
        $stock_qty = $variation_obj->get_stock_quantity();

        // The attributes taxonomy key and slug value for this variation
        $attributes_arr = $variation_obj->get_attributes();
    }

    if(count($attributes_arr) != 1) // Works only for 1 attribute set in the product
        return $term_name;

    // Get the terms for this attribute
    foreach( $attributes_arr as $attr_key => $term_slug){
        // Get the attribute taxonomy
        $term_key = str_replace('attribute_', '', $attr_key );

        // get the corresponding term object
        $term_obj = get_term_by( 'slug', $term_slug, $term_key );
        if( $term_obj->name == $term_name ){ // If the term name matches we stop the loops
            $second_loop_stoped = true;
            break;
        }
    }
    if($second_loop_stoped)
        break;
}
if( $stock_qty>0 )
    return $term_name .= ' - ' . $stock_status . ' ('.$stock_qty.')';
else
    return $term_name .= ' - ' . $stock_status;

}

但是在我的网站上进行测试时，对于所选产品的所有变化，它显示“缺货”。例如，在这个product上，它显示了我的所有变化的“缺货”，但实际上，只有变体“50ליטר”才真正“缺货”。其他变化有库存！我使用的是Woocommerce 3.3.5版本。有人可以告诉我，如果产品缺货是真的缺货，我需要做些什么来显示缺货，因为我使用单选按钮替代Woocommerce的标准下拉按钮。

似乎过于复杂，我设法这样做了。似乎工作，当我测试它时，显示缺货的正确变化。

add_filter( 'woocommerce_variation_option_name', 'customizing_variations_terms_name', 10, 1 );

function customizing_variations_terms_name( $term_name ) {

    global $product;
    // Get available product variations
    $product_variations = $product->get_available_variations();

    foreach ( $product_variations as $product_variation ) {
        if( isset( $product_variation['attributes'] ) ) {
            $key = array_search($term_name, $product_variation['attributes']);

            if( $key !== false && ! $product_variation['is_in_stock'] ) {
                return $term_name . ' - Out of Stock';
            }
        }
    }

    return $term_name;
}

除此之外，您可以使产品变灰，这样如果产品属于以后的产品，他们就无法选择产品。

add_filter( 'woocommerce_variation_is_active', 'grey_out_variations_when_out_of_stock', 10, 2 );

function grey_out_variations_when_out_of_stock( $grey_out, $variation ) {

    if ( ! $variation->is_in_stock() )
        return false;

    return true;
}

显示“缺货”文字，旁边是Woocommerce的变体
