Form value using array?

[JamesManke]

I am trying to create a variable from an array on my previous page.

page1.cfm ...

<form method="post" action="page2.cfm">
<CFLOOP INDEX="counter" FROM="1" TO="#ARRAYLEN(session.cart)#">
<input type="text" name="wrapit_#counter#" />
</CFLOOF>
</form>

page2.cfm ...

<CFLOOP INDEX="cart_count2" FROM="1" TO="#ArrayLen(session.cart)#">
<CFSET wrapit_temp = "form.wrapit_" & cart_count2>
<CFOUTPUT>
#wrapit_temp#<br />
</CFOUTPUT>
</CFLOOP>

I would like it to show the list of values BUT...
wrapit_temp comes out as "form.wrapit_temp" not the variable value.

Am I making sence?

Thanks for your help,

James

you're not setting the value of the variable you're looping through. try this.

<CFSET wrapit_temp = evaluate("form.wrapit_" & cart_count2)>

If you don't ask the right questions, you don't get the right answers. A question asked in the right way often points to its own answer. Asking questions is the ABC of diagnosis. Only the inquiring mind solves problems.

Or, you could just output the variable directly:

<CFOUTPUT>
  <CFLOOP INDEX="cart_count2" FROM="1" TO="#ArrayLen(session.cart)#">
     #Form["wrapit_#cart_count2#"]#<br />
  </CFLOOP>
</CFOUTPUT>

Hope This Helps!

ecobb's method is better. evaluate is kinda slow.
