Problem with multiple identical fields in form

Thanks Dan,

That got me on the right track although I didn't really use your method!

Below is my solution

FormPage:

<cfoutput>
<cfset i=0>
<cfloop query="cartList">
<cfset i=#i#+1>
<tr>
<th align="left"><input type="hidden" name="prod#i#" value="#prodID#" />#prodID#</th>
<td><input type="radio" name="colour#i#" value="Red" />Red</td>
<td><input type="radio" name="colour#i#" value="Blu" />Blue</td>
<td><input type="radio" name="colour#i#" value="Wht" />White
<input type="text" name="txt#i#" size="50" maxlength="100" />
<input type="hidden" name="txt#i#" value=",xxx," /></td>
</tr>
</cfloop>
<input type="hidden" name="noItems" value="#i#" />
</cfoutput>


Action Page

<cfloop from="1" to="#form.noItems#" step="1" index="i">
Product: #form["prod" & i]#, colour: #form["colour" & i]#, Text: #form["txt" & i]#<br />
</cfloop>

Instead of looping the entire product, why not just loop the colors associated to the product? Just have one product, then loop over the colors?

If you're unsure which fieldnames are being defined on your action page, you can always loop through the "FIELDNAMES" list.

You are approaching this the right way. The approach I generally use resembles:

<cfloop list="#form.fieldnames#" index = "ThisFieldName">
<cfif left(ThisFieldName is "prodId>
do something
etc

Hopefully you know how to use array notation with form fields.
