Blue Imps jQuery文件上传以正常字段的形式发送文件 [英] Blue Imps jQuery file upload send files with form like normal field

问题描述

是否可以像常规文件上传一样发送带有表单的文件?当我检查文件字段时，该字段始终为空，我需要在一次调用中将其与表单数据一起发送.有可能吗?

Is it possible to send file with form as normal file upload? When I check a file field it is always empty, and I need to send it with form data in one call. IS that possible?

推荐答案

可能会有更好的答案，但是我最终通过执行以下步骤解决了这个问题.

There might be better answers out there, but I ended up solving this by following steps.

1. 页面上有2个表单.一种用于文件上传，另一种用于其他表单数据.
2. 使用CSS设置两种格式的格式，以便用户获得一种形式的外观.
3. 只有一个div(看起来像按钮)可以提交.如果您正在使用它们，则隐藏实际表单的提交按钮(我不这样做，因为我先预处理数据然后通过ajax发送)
4. 一旦用户提交表单(通过单击虚拟按钮)，就可以使用JS以编程方式单击文件上载按钮.
5. 可选.该通话结束后，如果没有错误，则继续.
6. 将表单与其他表单数据一起提交.

1. Having 2 forms on the page. One for file upload and one for other form data.
2. Format both forms using CSS so that user gets look and feel of one form.
3. Have only one div (which looks like button) to submit. Hide the actual form's submit button, if you are using them (I don't. Because I preprocess data and then send by ajax)
4. Once user submits forms (by clicking the dummy button), Using JS programatically click the file upload button.
5. Optional Once that call is finished, if there are no errors only then continue.
6. Submit the form with other form data.

我使用这种方法的优势在于，我可以更好地控制用户的表单数据以及文件上载的设置.因为我有一些设置(例如最大文件数和最大文件大小)取决于用户的表单条目.

The advantage I had in this approach was that I could have more control over user's form data as well as my file upload's settings. Because I had some settings (like max number of files and max file size) were dependent on user's form entry.
