更新数据库后更新输入的值

Question

你好吗？我写信给他们咨询，我在function.php中有一个shotcode，我做的是在点击按钮时更新手机的值，但问题是它并没有将我更改为更新后的值，我有更新页面以显示新值。

 add_shortcode('editar-celular', 'get_current_user_prof');

      function get_current_user_prof() {
      global $current_user;
      get_currentuserinfo();
            if(is_user_logged_in()) {
$tableuserinf = "<form method='post' action='#'><table><tbody>";
$tableuserinf .= "<tr><td>Celular:</td><td><input type='text' name='phone' value='". $current_user->billing_phone ."'/></td></tr>";
                
$tableuserinf .= "</tbody></table><button>Submit</button></form>";
 
                $user_id = $current_user->ID;
// Not sure if sanitize_user() is needed or is executed by wp_update_user(). Anyway, it doesn't hurt
$phone = isset($_POST['phone']) ? sanitize_user($_POST['phone']) : '';
//check if new nickname is different before performing the update operation
if($phone != $current_user->billing_phone){
     
    
    update_user_meta($user_id, 'billing_phone', $phone  ) ;
}
return $tableuserinf;
                
} 

          }



EDIT VERSION 2:




 add_shortcode('editar-celular', 'get_current_user_prof');

      function get_current_user_prof() {
      global $current_user;
      get_currentuserinfo();
            if(is_user_logged_in()) {

                $user_id = $current_user->ID;
 
$phone = isset($_POST['phone']) ? sanitize_user($_POST['phone']) : '';

if($phone != $current_user->billing_phone){
       
    update_user_meta($user_id, 'billing_phone', $phone  ) ;
    
}

return "<form method='post'>
            <input type='text' name='phone' value='". $current_user->billing_phone ."' />
            <input type='submit' value='Validate' />
            </form>";
                
} 

          }
