Problem with multiple identical fields in form

[Mi-ul-vmijiI]

Hi

I'm having a problem with a form - the easiest way to describe it is like a shopping cart which gives you the product ID then a choice (radio buttons) of 3 colours and then a free text box.

My problem is where I have 4 of these rows. I can use a counter to rename the form fields (prodID#COUNTER#, col#COUNTER# =Red/Blu/Wht, description#COUNTER#) but then I'm struggling to deal with these in a loop on the action page.

Am I approaching this the right way in the form and what is the best method in the action?

Many thanks
Michael

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.

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.

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>
