Save attributes befor update product

Hi, shure, that’s the code:

`//CREATE BUTTON IN THE BACKEND FOR AUTOFILL SHORT DESCRIPTION AND TAGS
add_action( ‘post_submitbox_misc_actions’, function() { #add a button near the publish/update button
global $post;

$attribute_names_for_tags = array( ‘pa_marca’, ‘pa_modello’, ‘pa_tipologia’, ‘pa_tipo-prodotto’, ‘pa_codice-oem’, ‘pa_codice-concorrenza’, ‘pa_stato’ ); #get the taxonomies for autofill tags

foreach ( $attribute_names_for_tags as $attribute_name ) {
$taxonomy = get_taxonomy( $attribute_name );

if ( $taxonomy && ! is_wp_error( $taxonomy ) ) {
$terms = wp_get_post_terms( $post->ID, $attribute_name );
$terms_array = array();

if ( ! empty( $terms ) ) {
foreach ( $terms as $term ) {
$archive_link = get_term_link( $term->slug, $attribute_name );
$full_line = $term->name;
array_push( $terms_array, $full_line );
}
$tags .= implode( $terms_array, ‘, ‘ ).’,’;
}
}
}

$attribute_names_for_desc = array( ‘pa_marca’, ‘pa_modello’, ‘pa_codice-oem’, ‘pa_codice-concorrenza’ ); #get the taxonomies for autofill short-description

foreach ( $attribute_names_for_desc as $attribute_name ) {
$taxonomy = get_taxonomy( $attribute_name );

if ( $taxonomy && ! is_wp_error( $taxonomy ) ) {
$terms = wp_get_post_terms( $post->ID, $attribute_name );
$terms_array = array();

if ( ! empty( $terms ) ) {
foreach ( $terms as $term ) {
$archive_link = get_term_link( $term->slug, $attribute_name );
$full_line = $term->name;
array_push( $terms_array, $full_line );
}
$short_desc .= ucwords(ltrim(str_replace(‘-‘, ‘ ‘, $taxonomy->name), ‘pa_’)) . ‘: ‘ . implode( $terms_array, ‘, ‘ ).'<br>’;
}
}
}
