您可以提交的表单字段数量是否有限制？ [英] Is there a limit to the number of form fields you can submit?

问题描述

我有一个相当长的表单（1000个复选框），客户通过订购。
但是当超过一定限制（100项）时，我会收到以下错误：

I have a rather long form (1000 checkboxes) that the customer goes through to order. But I get the following error when it goes over a certain limit (100 items):

无法添加HTML标题。 ColdFusion无法将
指定的标头添加到输出流。这可能是因为您有
已在您的模板中使用了cfflush标记或缓冲输出是
已关闭

Failed to add HTML header.ColdFusion was unable to add the header you specified to the output stream. This is probably because you have already used a cfflush tag in your template or buffered output is turned off

Q：是IIS设置还是ColdFusion管理员设置？

Q: Is that an IIS setting or a ColdFusion administrator setting?

我在发布这个问题之前做了一些研究，它不需要使用AJAX和debug设置。所有调试设置都已关闭，我在表单提交时收到错误。

I did some research before posting this question, and it doesn't have to do with AJAX and debug settings. All debug settings are turned off and I get the error on form submit.

推荐答案

如果是GET，您可能会超出网址长度限制。如果它是一个POST，那么你可能正在运行到CF的限制在表单字段的数量。 本文详细说明如何修改值。

Does your form POST or GET? If it's a GET you may be maxing out the URL length limit. If it's a POST, then you are probably running into the limit in CF on the number of form fields. This article details how to modify the value.

您可能需要考虑将该数据发送到服务器的其他方法。也许使用jQuery来序列化表单并将JSON作为单个参数发送？

You may want to consider other ways of sending that data to the server. Perhaps using jQuery to serialise the form and send the JSON as a single parameter?
