Multiple upload controls on page

[jmestep]

I'm customizing some admin pages where the client needs to upload images for some new custom fields. I've taken some of the code from digital files upload code, put it into a user control, and put that user control multiple times on the admin page with different id tags. It works fine as far as saving the url of the file to the correct field and uploading the file to the server.
But if I put the validation back on and the script to set the file uploaded name to the file name box, I run into problems. I know what the problem is, but I don't know how to fix it.
One of the problems is with the javascript to set the name into the text box- it has UploadFile. as the name of the control and I have an UploadFile1 and an UploadFile2. How can I get it to loop thru both of the controls? Here is the javascript:

Code: Select all

<script type="text/javascript" language="javascript">
            var lastName1="";var lastName2="";function setNames(){var a=document.getElementById("<%= UploadFile.ClientID %>").value;if(a.length>0){var b;var c=a.lastIndexOf("\\");if(c<0){c=a.lastIndexOf("/");if(c<0){b=a}else{b=a.substring(c+1)}}else{b=a.substring(c+1)}var f=document.getElementById("<%= UploadFileName.ClientID %>");if((f.value.length==0)||(f.value==lastName2)){b=b.replace(/ /g,"_");f.value=b;lastName2=b}}}
        </script>

Thanks
