Facebook注册插件提供错误

Question

我正在使用下面的iframe代码在我的网站上为用户注册提供一个表单。虽然当我在一定数量的自定义字段后面添加自定义字段时，我会得到一个错误，即：

坏请求您的浏览器发送了此服务器无法理解的请求。请求标头字段的大小超过服务器限制。裁判/n

我试着联系我的主机帮助，他们说facebook代码有问题，但我想这不是问题所在，因为在一定数量的复选框中，代码工作正常，但一旦超出这个范围，我就会得到上面的错误。以下是守则：

有人能猜到我哪里出了问题吗？我正在使用给定的这里示例代码按php处理表单。如果需要，请询问代码，我也将提供php代码，但它几乎与上面链接上的示例相同。

Answer 1

"get“请求通常是有限制的。因此，当您返回到服务器时，得到的get请求超过了这个限制。(限制由Apache配置设置)。与Facebook无关，这个限制是由你的主机提供商设定的，所以你问他们是对的。

选项：

1. 要求主机提供商提高限制(不太可能)
2. 将数据存储在会话变量中，或存储在连接到唯一id的数据库表中。返回时，从会话中获取数据，或者使用唯一id作为发送给Facebook的参数，并使用该唯一id作为回报来建立完整的data.this方法，还有其他优点(显示较少的数据，允许终端用户进行更少的操作)。
