检查是否未重新分配$name变量：

$name = $_POST['name'];
UPDATE g SET name='$name'

更改变量名并尝试将其传递给db：

 $name_new = $_POST['name'];
UPDATE g SET name='$name_new'

当您不在db中插入某些内容而其他表插入时，最大可能的情况是您不传递任何内容，另一种情况是您的db“name”表没有为字符串分配任何内容，例如，如果您将“id”表的名称更改为“name”，它将不会保存字符串。尝试传递到db自定义“name”，而不是从变量传递，如

"UPDATE g SET name='somewords'

如果它保存了，那么问题就出在您的变量中；如果它没有保存，而其他人保存了，那么问题就出在您的表conf上

执行UPDATE语句时，您知道您正在覆盖SELECT语句的结果吗？因此，在这种情况下，while循环将不起作用。您还完全可以使用while循环，而不是串联查询。特别是因为你根本没有逃避用户的输入！如果其他行发生更改，则是sb问题。检查“名称”行规格，如类型和长度。您是否使用“id”行？
