Change the price of a product

Describe your question

Hello,

i want to change the price of a product whenever it changes on the original, so the copied product will have a percentage of the original.

I tried like this and failed:
`/**

• Set default post meta if not set in the original.
• @param {array} $meta All received meta for the post
• @param {array} $existing_meta Existing meta for the post
• @param {int} $post_id Post ID
  */
  function client_prefix_modify_meta( $post_meta, $existing_meta, $post_id ) {
  // Set post meta if not set.
  $existing_meta[ '_regular_price'] = '45.55';
  $existing_meta[ '_sale_price'] = '34.55';
  $existing_meta[ 'post_regular_price'] = '645.55';
  $existing_meta[ 'post_sale_price'] = '634.55';
  }
  add_action( 'dt_after_set_meta', 'client_prefix_modify_meta', 10, 3 );

add_filter( 'dt_push_post_meta', function( $a, $new_post_id, $post_meta, $post_id, $args, $connection ) {

// $field_prefix =( $connection instanceof \Distributor\ExternalConnections\WordPressExternalConnection ) ? '' : 'post_';

$post_meta[ '_regular_price'] = '45.55';
$post_meta[ '_sale_price'] = '34.55';
$post_meta[ 'post_regular_price'] = '645.55';
$post_meta[ 'post_sale_price'] = '634.55';

return true;

},10,6);

/**

• Keep the publication date on the new pushed post.

• This filter is used to filter the arguments sent to the remote server during a push. The below code snippet passes the original published date to the new pushed post and sets the same published date instead of setting it as per the current time.
  */
  add_filter( 'dt_push_post_args', function( $post_body, $post, $args, $connection ) {

  // When pushing to an external connection, we use the REST API, so the name of the field is date.
  // But when pushing to an internal connection, the attributes are sent to wp_insert_post, which expects post_date.
  $field_prefix =( $connection instanceof \Distributor\ExternalConnections\WordPressExternalConnection ) ? '' : 'post_';

  $post_body[ $field_prefix . 'date'] = $post->post_date;
  $post_body[ $field_prefix . 'date_gmt'] = $post->post_date_gmt;
  $post_body[ $field_prefix . 'regular_price'] = $post->regular_price-10;
  $post_body[ $field_prefix . 'sale_price'] = '3';
  $post_body[ $field_prefix . 'description'] = 'chris4';
  $post_body[ $field_prefix . 'content'] = "chris4w";

  return $post_body;
  }, 10, 4 );
