This Code Snippet will work:

for ( $i = 0; $i <= max( array_keys( $variable_sku ) ); $i++ ) 
{
	$variation_id = (int) $variable_post_id[$i];

	if ( isset( $_checkbox[$i] ) ) 
	 {
		Helper_Functions::save_checkbox_meta( $variation_id, 'yes' );
		continue ;
	 } 
	else 
	 {
		Helper_Functions::save_checkbox_meta( $variation_id, 'no' );
	 }
}

Can try this, in 2021 if you want the custom variation product field to be saved.

add_action('woocommerce_save_product_variation', 'jenn_custom_variation_product_save_fields', 10, 2);
function jenn_custom_variation_product_save_fields($variation_id, $i) {
	if( !empty( $_POST['your_custom_field_name'] ) ) {
		//variable product
		$_your_custom_field = $_POST['your_custom_field_name'];
		update_post_meta( $variation_id, 'your_custom_field',  $_your_custom_field[$i] );
	}
}

Me pueden ayudar a poner un texto cualquiera despues del precio, sin que aparezca en la pagina del producto, solo en la principal.
Tengo este código:
`add_action( 'woocommerce_product_options_general_product_data', 'woo_anadir_sufijo', 10);
function woo_anadir_sufijo() {
global $woocommerce;

// CAMPO DE EDICIÓN DE TEXTO DEL SUFIJO.
woocommerce_wp_textarea_input(
array(
'class' => array('large_windows_sufijo'),
'id' => '_sufijo',
'label' =>__( 'Sufijo detras del precio(F)', 'woocommerce' ),
'placeholder' => 'Pej: Sin IVA, (+IVA), En liquidación, Últimas unidades, Artículo rabajado, Por m2, Por litro, En oferta....',
'desc_tip' => 'true',
'description' => __( '

SUFIJO PERSONALIZADO EN PRECIOSAñada aquí un texto personalizado a modo de sufijo para que se muestre detras del precio del producto principal para informar a sus clientes de alguna característica destacada sobre él o sobre cantidades incluidas etc. Pej: Sin IVA, (+IVA), En liquidación, Artículo rabajado, Por m2, Por litro, En oferta, 100g o100 Piezas por caja etc.... o una combinación de varios. Este sufijo se mostrará en los productos de la parrilla de cada categoría y en el precio de producto principal..', 'woocommerce' )));
}

// GUARDA EL CAMPO DEL SUFIJO EN LA DB.
add_action( 'woocommerce_process_product_meta', 'woo_salvar_sufijo' );
function woo_salvar_sufijo( $post_id ){
$woocommerce_sufijo = $_POST['_sufijo'];
if( isset( $woocommerce_sufijo ) )
update_post_meta( $post_id, '_sufijo', esc_attr( $woocommerce_sufijo ) );
}
// echo get_post_meta(get_the_ID(), 'wc_price_per_unit_key', true);
// MUESTRA EL SUFIJO DETRAS DEL PRECIO EN EL PRODUCTO PRINCIPAL Y EN LOS DE LA PARRILLA
add_filter('woocommerce_get_price_html','anade_sufijo_detras_del_precio');
function anade_sufijo_detras_del_precio( $price ) {
$price .= ' ' . get_post_meta(get_the_ID(), '_sufijo', true);
return $price;
add_action( 'woocommerce_before_calculate_totals', 'anade_sufijo_detras_del_precio' ); // Esta línea coloca el sufijo en el producto principal.
add_action( 'woocommerce_after_shop_loop_item_title', 'anade_sufijo_detras_del_precio', 11 ); // Esta línea coloca el sufijo en los productos de la parrilla.
}
Lo que pasa es que borro esta linea, pero me sigue apareciendo el texto en la pagina de productoadd_action( 'woocommerce_before_calculate_totals', 'anade_sufijo_detras_del_precio' ); // Esta línea coloca el sufijo en el producto principal.`
