常見問題

常見問題:

Uncaught Error: mysqli_stmt_bind_param(): Argument #3 cannot be passed by reference

因為mysqli_stmt_bind-param()，只能使用變數:

      mysqli_stmt_bind_param($stmt, "i", 1);

要改為:

      mysqli_stmt_bind_param($stmt, "i", $postid);

如果一定要寫死，那就寫在$sql裡

    $sql="iINSERT INTO `user` (`account`, `password`, `role`, `name`, `created_at`) VALUES (?, ?, 'U', ?, now())";
