wordpress - Automatic Update all posts at once -

i made changes in plugin creates meta boxes, added tome default code "value" of meta box. data being sent outside. problem need press "update" on every woocommerce product permanently saved , sent. have 1500 products.

i have tried bulk updating general admin area, shawn here: https://bobwp.com/bulk-edit-posts-wordpress/

it didn't work. tried code:

$args = array(     'posts_per_page' => 1000,     'post_type' => 'product'     ); $the_query = new wp_query( $args );  if ( $the_query->have_posts() ) {      while ( $the_query->have_posts() ) {         $the_query->the_post();         $casa_id = $post->id;         update_post_meta($post->id, 'casa_id', $casa_id);     } } 

and this:

function woo_zap_update_product_name() {      if ( ! is_admin() ) {         return;     }      $zap_query = new wp_query( array( 'post_type' => 'product', 'posts_per_page' => -1 ) );      if ( $zap_query->have_posts() ) {          global $post;          while ( $zap_query->have_posts() ) {             $zap_query->the_post();             update_post_meta( $post->id, '_wc_zap_product_name', $post->post_title );         }          wp_reset_postdata();     } } add_action( 'init', 'woo_zap_update_product_name' ); 

didn't work well.. other ideas ?
