Set variables in a loop

calista · Jul 13, 2001

Hi, folks!

I am trying to replace the following code on my form action page with a loop:

Code:

<CFIF ISDEFINED(&quot;Form.FOPEN&quot;) IS TRUE>
	<CFSET FOPEN=&quot;Yes&quot;>
<CFELSE>
	<CFSET FOPEN=&quot;No&quot;>
</CFIF>
<CFIF ISDEFINED(&quot;Form.FCLOSE&quot;) IS TRUE>
	<CFSET FCLOSE=&quot;Yes&quot;>
<CFELSE>
	<CFSET FCLOSE=&quot;No&quot;>
</CFIF>
<CFIF ISDEFINED(&quot;Form.FREAD&quot;) IS TRUE>
	<CFSET FREAD=&quot;Yes&quot;>
<CFELSE>
	<CFSET FREAD=&quot;No&quot;>
</CFIF>
<CFIF ISDEFINED(&quot;Form.FWRITE&quot;) IS TRUE>
	<CFSET FWRITE=&quot;Yes&quot;>
<CFELSE>
	<CFSET FWRITE=&quot;No&quot;>
</CFIF>

Here's what I've got so far:

Code:

<CFSET FileEventList = &quot;FOPEN,FCLOSE,FREAD,FWRITE&quot;>

<CFLOOP INDEX=&quot;EventIndex&quot; FROM=&quot;1&quot; TO=&quot;4&quot; STEP=&quot;1&quot;>
	<CFPARAM NAME=&quot;Form.#ListGetAt(FileEventList,EventIndex)#&quot; DEFAULT=&quot;False&quot;>
</CFLOOP>
<CFOUTPUT>
	<CFLOOP INDEX=&quot;EventIndex&quot; FROM=&quot;1&quot; TO=&quot;4&quot; STEP=&quot;1&quot;>
		#ListGetAt(FileEventList,EventIndex)#    #Evaluate(ListGetAt(FileEventList,EventIndex))#<BR>
	</CFLOOP>
</CFOUTPUT>

This sets an initial value correctly, but as you can see from my original code, if the box is checked, the varable S/B "Yes", if it is not checked it S/B "No". Later, these values are inserted into the database. I can't seem to set variables dynamically. Is what I'm trying to do possible? I hope so, because this is the easy one. It gets uglier from here.

Thanks!

Hey Calista,

It looks like you're attempting to solve the problem of how to deal with check boxes that aren't checked. I would suggest using radio buttons since it appears these are all yes/no type settings.

If that's not an option, I would think something like this will work (haven't tested it).

<CFSET FileEventList = "FOPEN,FCLOSE,FREAD,FWRITE">
<CFLOOP INDEX="x" list=#fileEventList#>
<cfset "#x#" = IIF( isdefined("form.#x#&quot

,DE("Yes&quot

,DE("No&quot

)>
</CFLOOP>

Hope this helps,
GJ

This seems of work. I give the checkbox a value of "Yes" on the form page, on the action page, I use CFPARAM to set all of them to "No". Then I loop through the respones. If the box was checked, the form variable is set to "Yes", if it was not, the form variable is set to the default, "No". Here's the code for anyone who's interested:

Form Page

Code:

<!DOCTYPE HTML PUBLIC &quot;-//W3C//DTD HTML 4.0 Transitional//EN&quot;>

<HTML>
<HEAD>
	<TITLE>Test Form Page</TITLE>
</HEAD>

<BODY>

<CFSET FILEEVENTLIST = &quot;FOPEN,FCLOSE,FREAD,FWRITE&quot;>

<CFOUTPUT>
<FORM ACTION=&quot;TestAction.cfm&quot; METHOD=&quot;post&quot;>
	<CFLOOP INDEX=&quot;X&quot; LIST=&quot;#FileEventList#&quot;>
		#X#   <INPUT TYPE=&quot;checkbox&quot; NAME=&quot;#X#&quot; VALUE=&quot;Yes&quot;><BR>
	</CFLOOP>
	<BR><BR>
	<INPUT TYPE=&quot;submit&quot; NAME=&quot;Submit&quot; VALUE=&quot;Submit&quot;>
</FORM>
</CFOUTPUT>

</BODY>
</HTML>

And, here is the action page:

Code:

<!DOCTYPE HTML PUBLIC &quot;-//W3C//DTD HTML 4.0 Transitional//EN&quot;>
<HTML>
<HEAD>
	<TITLE>Test Action Page</TITLE>
</HEAD>
<BODY>

<CFSET FILEEVENTLIST = &quot;FOPEN,FCLOSE,FREAD,FWRITE&quot;>

<CFLOOP INDEX=&quot;EventIndex&quot; FROM=&quot;1&quot; TO=&quot;4&quot; STEP=&quot;1&quot;>
	<CFPARAM NAME=&quot;Form.#ListGetAt(FileEventList,EventIndex)#&quot; DEFAULT=&quot;No&quot;>
</CFLOOP>

<CFOUTPUT>
	<CFLOOP INDEX=&quot;EventIndex&quot; FROM=&quot;1&quot; TO=&quot;4&quot; STEP=&quot;1&quot;>
		#ListGetAt(FileEventList,EventIndex)#    #Evaluate(ListGetAt(FileEventList,EventIndex))#<BR>
	</CFLOOP>
</CFOUTPUT>
<BR><BR>
<CFOUTPUT>
	Form.FOPEN 	EQ #Form.FOPEN#<BR>
	Form.FCLOSE EQ #Form.FCLOSE#<BR>
	Form.FREAD 	EQ #Form.FREAD#<BR>
	Form.FWRITE EQ #Form.FWRITE#<BR>
</CFOUTPUT>
</BODY>
</HTML>
