嘿傢伙我卡在一個點。我有一種情況，我需要上傳縮放的圖像在不同的文件夾中，例如： - 1（小）。小文件夾爲jpg，中文文件夾爲1（中），.jpg和上傳文件夾爲1.jpg。現在下面的代碼將所有3張圖片上傳到不同的文件夾，但是這些文件是blob文件。如何獲得縮放圖像。 （編輯的代碼）下面精細上傳w /冷融合上傳縮放圖像在不同的文件夾
<cfset destinationDirectory = expandpath('/file_uploader/uploads')>
<cfset counter = 1>
<cfset uniqueFileName = "">
<cfset destinationFilePath = "">
<cfset smallfile = "">
<cfset mediumfile ="">
<cfset mainfile= ''>
<cfscript>
variables.validMimeTypes = {'image/jpeg': {extension: 'jpg'}
,'image/png': {extension: 'png'}
,'image/png': {extension: 'gif'}
}; </cfscript>
<cftry>
<cfset cnt= 1>
<cfset file_name = #qqfilename#>
<cfset file_size = #qqtotalfilesize#>
<!--- If a file with the same name already exists at the destination --->
<cfif fileExists(destinationDirectory & "/" & file_name)>
<!--- Loop up to 100 times to try create a unique file_name --->
<cfset destinationFilePath = destinationDirectory & "/" & counter & "_" & file_name>
<!--- Loop up to 100 times to try create a unique filename --->
<cfloop condition="counter LT 100">
<cfset destinationFilePath = destinationDirectory & "/" & counter & "_" & file_name>
<cfif fileExists(destinationFilePath)>
<cfset counter++>
<cfelse>
<cfset uniqueFileName = "IMG" & counter & "_" & file_name>
<cfbreak/>
</cfif>
</cfloop>
<!--- Filename does not already exist at the destination --->
<cfelse>
<cfset uniqueFileName = "IMG" & "_" & file_name>
<cfset destinationFilePath = destinationDirectory & "/" & file_name>
</cfif>
<cfif len(trim(uniqueFileName))>
<cfset session.cntr ++>
<cfif find("(small)",file_name) neq 0>

與您的問題無關，但您不需要循環來生成唯一的文件名。附加一個UUID或者getTickCount（）的結果應該可以做到。 –
你試過看文件名嗎？ –
...和@丹也是正確的。 Fine Uploader已經爲您提供了每個文件的uuid。我不知道爲什麼你選擇了遍歷文件名，添加一個計數器變量，直到名稱是「唯一的」。 –
