Question

我在表单中有2个提交按钮。当我点击一个“上传”按钮时，我将上传一个文件并保存在服务器的文件路径中。当我点击另一个名为“Process”的按钮时，我想在代码中使用这个文件路径。当我单击该过程时，在下面的代码中没有发生任何转储。表格提交给自己。有没有更好的方法来做到这一点。提前谢谢。

<table width="40%" border="0" style="border: 1px solid black;">

<form  name="uploadform" action="processfile.cfm" enctype="multipart/form-data"  

method="post">

 <tr>
    <td><input type="file"  name="FileContents" size="25">

        <input type="button" name="action" id="action" value="Upload">

   </td>

   </tr>

    <tr>
       <td align="middle">

      <input type="button" name="submitaction" id="process" value="Process">

       </td>

   </tr>

    </form>

 </table>

<!---Clicking the fist button to upload--->

 <cfset variables.filepath ="">

<cfif isdefined("form.action") AND form.action eq "upload">

<cffile action = "upload"  fileField = "FileContents" destination = "C:\test\" accept = "text/plain" nameConflict="overwrite">

<cfset variables.filepath= "C:\test\#cffile.serverFile#">

<!---Clicking the second button to process--->  

    <cfelseif isdefined("form.submitaction") AND form.submitaction eq "process">

              <cfdump var="#variables.filepath#">
    </cfif>

Answer 1

您的转储未发生的原因是<input type="button">除非您通过JavaScript执行此操作，否则不会提交表单。

请阅读Difference between <input type='button' /> and <input type='submit' />

Answer 2

您可以尝试以下代码。这也会转储路径的值。

<cfif isDefined('Form.tmpfile1')>
    <cfset root = ExpandPath("/Upload")><!---location where file should be uploaded--->
    <cfset filename=GetFileFromPath(Form.tmpFile1)>
    <cfset FileExt=ListLast(filename,".")>
    <cfset variables.filepath ="">      
    <cfset filename = "BidDocument1." & FileExt>

    <cffile action="upload" 
            filefield="BidDoc1" 
            destination="C:\Upload\" 
            nameconflict="overwrite" 
            accept="application/pdf,application/msword,application/vnd.ms-excel,text/plain,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet">
    <cfset variables.filepath= "C:\test\#cffile.serverFile#">
    <cfdump var="#variables.filepath#">
</cfif>

        <form name="form1" enctype="multipart/form-data" method="post">
            <input type="hidden" name="tmpfile1" value="" />
            <input  type="file"  name="BidDoc1"  onchange="setFile(this.form);" />
            <input type="submit" name="save1" value="Upload" />  
        </form>
        <button onclick="location.href='processfile.cfm'">Process</button>
</html>

这应该对你有帮助。
