Checking to see what button the user pressed.

Hi,

You can add additional rows already on the server in CF, but hide them with CSS, and have the add button just switch them to visible (with a little java script), like in the sample below.

cheers,
fober


<cfset number_of_fields= 15>

<cfoutput>
<cfloop index="x" from="1" to="#number_of_fields#">

<cfif x IS 1>
<cfset style= "display:block;">
<cfelse>
<cfset style= "display:none;">
</cfif>

<div id="field#x#" style="#style#">
<input type="File" name="field#x#"><br>
</div>
</cfloop>
</cfoutput>

<input type="Button" id="btn_add" onclick="visible_add('field')" value="Add File">

<script language="JavaScript">
function visible_add(id){
var counter= 1;

do{
obj= document.getElementById(id + counter);
if ( obj.style.display == 'none') {
obj.style.display= 'inline';
return;
}
counter++;
}while ( document.getElementById(id + counter) != null )

document.getElementById('btn_add').style.display = 'none';
}
</script>

Thank you very. Well appreciated.

Yes.

NO!

ColdFusion only runs on the server, it will never know what was happened
until it receives another request from the client, which would require
some type of submit.

You are looking for a client solution. And there are many out there
that will do just what you are asking to do. Using JavaScript, DHTML
and possible AJAX techniques, you can easily have the client browser add
new form elements when a user activates a given control.

You are going to invoke JavaScript functions to manipulate the DOM
(Document Object Model). There are several JavaScript frameworks thet
build this in.

Hopefully I have given you enough key words to do a successful search
from the many tutorials and examples on how to do this. Because such an
explanation is much to larger to fit into the space of this reply.
