文件上传正在执行多次

Question

我试图创建一个表单，用户在其中选择一个位置，然后用CFFILE ACTION ="UPLOAD"上传一个文档。我不擅长这一点，所以你可以提供任何帮助将不胜感激。

以下是我的代码。本质上，有一个文件夹位置的下拉列表。用户首先选择其中一个位置。然后点击'浏览'选择一个文件。最后他们点击提交和文件上传。

代码是#dir#是链接到每个位置名称的文件夹位置。目前发生的事情是，文档已成功上传...但它正在上传到所有文件夹位置，而不是从下拉列表中选择的位置。这里是我的代码：

docuploads.cfm

<cfquery name="getLocation"> 
    SELECT * 
    FROM Locations 
    ORDER BY FolderName 
</cfquery> 

<form action="docuploads.cfm" method="POST" enctype="multipart/form-data" name="upload_form" id="upload_form"> 
    <select name="folderID"> 
     <option value="">--- Select Folder ---</option> 
     <cfoutput query="getLocation"> 
      <option value="#FolderName#"">#FolderName#</option> 
     </cfoutput> 
    </select> 

    <cfoutput query="getLocation"> 
     <CFIF IsDefined("form.upload_now")> 
      <CFIF structKeyExists(form, "ul_path") and len(form["ul_path"])> 
      <CFFILE ACTION="UPLOAD" FILEFIELD="ul_path" 
        DESTINATION="C:\Documents\#dir#\"   
        NAMECONFLICT="OverWrite"> 
       <CFSET ClientFilePath = "#clientDirectory#\#clientFile#"> 
      </CFIF> 
     </CFIF> 
    </CFOUTPUT> 

    <br /><br /> 
    Click on the Browse button to select the file to Upload:<br> 
    <input type="file" name="ul_path" id="ul_path" style="height: 22px;width: 350px;" value=""><br><br> 
    <input type="submit" name="upload_now" id="upload_now" value="Submit" style="height: 22px;"> 
    <input type="button" name="clear" value="Clear" style="height: 22px;"> 
    <br /><br /><br /> 
</form> 

我希望这是有道理的 - 任何人都可以摆脱对得到这个工作任何光线？

我假设你没有发布完整的代码，因为你的#clientDirectory#/#clientFile#在你的代码中似乎没有源代码。

我把它看起来可能的样本放在一起。为了便于阅读，我还将您的上传例程从代码主体移至顶端。

<CFIF IsDefined("form.upload_now")> 
    <CFIF structKeyExists(form, "ul_path") and len(form["ul_path"])> 

     <!--- assuming you need to lookup info from the database ---> 
     <cfquery name="getThisLocation"> 
      SELECT FolderID, FolderName, dir 
      FROM Locations 
      where foldername=#form.folderid# 

     </cfquery>  


     <CFFILE ACTION="UPLOAD" FILEFIELD="ul_path" 
        DESTINATION="C:\Documents\#getThisLocation.dir#\"   
        NAMECONFLICT="OverWrite"> 

     <CFSET ClientFilePath = "#getThisLocation.clientDirectory#\##getThisLocation.clientFile#"> 

    </CFIF> 
</CFIF> 


<cfquery name="getLocation"> 
    SELECT * 
    FROM Locations 
    ORDER BY FolderName 
</cfquery> 

<form action="docuploads.cfm" method="POST" enctype="multipart/form-data" name="upload_form" id="upload_form"> 

<CFIF IsDefined("form.upload_now")> 
    <CFIF structKeyExists(form, "ul_path") and len(form["ul_path"])> 
    <P>FILE UPLOADED</P> 
    </CFIF> 
</CFIF> 

    <select name="folderID"> 
     <option value="">--- Select Folder ---</option> 
     <cfoutput query="getLocation"> 
      <option value="#FolderName#"">#FolderName#</option> 
     </cfoutput> 
    </select> 



    <br /><br /> 
    Click on the Browse button to select the file to Upload:<br> 
    <input type="file" name="ul_path" id="ul_path" style="height: 22px;width: 350px;" value=""><br><br> 
    <input type="submit" name="upload_now" id="upload_now" value="Submit" style="height: 22px;"> 
    <input type="button" name="clear" value="Clear" style="height: 22px;"> 
    <br /><br /><br /> 
</form> 

我还添加了一段代码让用户知道文件已上传。

请试试这个：

<CFIF IsDefined("form.upload_now")> 
     <CFIF structKeyExists(form, "ul_path") and len(form["ul_path"])> 
     <CFFILE ACTION="UPLOAD" FILEFIELD="#form.ul_path#" 
       DESTINATION="C:\Documents\#dir#\"   
       NAMECONFLICT="OverWrite"> 
      <CFSET ClientFilePath = "#clientDirectory#\#clientFile#"> 
     </CFIF> 
     <cfoutput>file uploaded successfully</cfoutput> 
    </CFIF> 

<cfquery name="getLocation"> 
    SELECT * 
    FROM Locations 
    ORDER BY FolderName 
</cfquery> 

<form action="docuploads.cfm" method="POST" enctype="multipart/form-data" name="upload_form" id="upload_form"> 
    <select name="folderID"> 
    <option value="">--- Select Folder ---</option> 
    <cfoutput query="getLocation"> 
     <option value="#FolderName#"">#FolderName#</option> 
    </cfoutput> 
</select> 

    <br /><br /> 
Click on the Browse button to select the file to Upload:<br> 
<input type="file" name="ul_path" id="ul_path" style="height: 22px;width: 350px;" value=""><br><br> 
<input type="submit" name="upload_now" id="upload_now" value="Submit" style="height: 22px;"> 
<input type="button" name="clear" value="Clear" style="height: 22px;"> 
<br /><br /><br />
