ColdFusion处理HTML5< input type =" file" multiple =“multiple” /> [英] ColdFusion handling of HTML5 <input type="file" multiple="multiple" />

问题描述

我想实现一个HTML5输入字段，让用户选择多个文件上传。我有以下形式的：

 < form method =postenctype =multipart / form-dataaction =index.cfm> 
< input type =filename =Imagesid =Imagesmultiple =multipleaccept =image / jpeg，image / gif，image / png，application / zip/> 
 ... 
  

我可以在浏览器中选择多个文件， ，但我不知道如何处理与ColdFusion的表单。我认为以下会工作，但这只是上传我选择的最后一个文件：

 < cfloop list =图片＃index =图片> 
< cffile 
 destination =#ExpandPath（Trim（request.TempFolder））＃
 filefield =Images
 action =upload
 nameconflict = MakeUnique
 result =UploadedTempFile
> 
< cfoutput>＃UploadedTempFile.serverFile＃< br />< / cfoutput> 
< / cfloop> 
  

有人可以向我解释如何遍历通过我的一个表单字段提交的所有文件，

：从ColdFusion 9开始，这是真的。

因此，为了包装我们的评论对话：

t可能与默认ColdFusion行为。 cffile 不支持从单个文件元素处理多个文件上传。我认为有可能回到JAVA做这个，但我不会有一个线索如何使这种情况。

我会爱 cffile action =uploadall来抓取所有HTML5多文件元素。需要将其作为CF10的ER文件：）。

I am trying to implement an HTML5 input field that lets the user select multiple files to upload. I have the following in my form:

<form method="post" enctype="multipart/form-data" action="index.cfm">
    <input type="file" name="Images" id="Images" multiple="multiple" accept="image/jpeg, image/gif, image/png, application/zip" />
    ...

I am able to select multiple files in the browser, then click upload, but I'm not sure how to handle the form post with ColdFusion. I thought the following would work, but this only uploads the last file I selected:

<cfloop list="#attributes.Images#" index="Image">
    <cffile
        destination = "#ExpandPath(Trim(request.TempFolder))#"
        filefield = "Images"
        action = "upload"
        nameconflict = "MakeUnique"
        result = "UploadedTempFile"
    >
    <cfoutput>#UploadedTempFile.serverFile#<br /></cfoutput>
</cfloop>

Can someone explain to me how to loop through all the files submitted through my one form field so I can handle the files individually?

解决方案

UPDATE: As of ColdFusion 9 this was true. This has been corrected in ColdFusion 10.

So to wrap up our comment conversation:

This simply isn't possible with default ColdFusion behavior. cffile doesn't support handling multiple file uploads from a single file element. I think it could potentially be possible to fallback to JAVA to do this, but I wouldn't have a clue how to make that happen.

I would love cffile action="uploadall" to grab all HTML5 multi-file elements. Will need to file that as an ER for CF10 :).
