[thelist] Uploading multiple files using cold fusion <cffile> + javascript

 -- no, it is not possible to manipulate the contents of an <input
type="file" ...>  field using JavaScript.  Sit back and think about it for a
second. If it *was possible*, I'd be able to build a script that looked for
fun files on your computer, dropped them into the form field and then upload
them to my server.  Major security risks with this.

You can however, still upload multiple files to a ColdFusion template:


html page:
-----------------------------------
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="file1">

<input type="file" name="file2">

<input type="file" name="file3">
<submit>
</form>
-----------------------------------


cfm template:
-----------------------------------
<cfif IsDefined("form.file1">
 <cftry>
	<cffile
	action="upload"
	filefield="#form.file1#"
	destination="#pathToSave#" >

	<cfcatch type="any">
	</cfcatch>
</cftry>
</cfif>
-----------------------------------
