Hi, what’s wrong in the above code?
Im trying to pass a variable outside the loop but I get this error:

Trying to get property ‘numero_doc’ of non-object

$posts = new WP_Query( $args );

if( $posts ):

 foreach( $posts as $post ): 
        
       setup_postdata( $post );

$number = $post->numero_doc;

endforeach;
wp_reset_postdata();
endif;

}
 $field['default_value'] = $number + 1;
  return $field;
}

What do you think that $post->numero_doc should be?
