cfset / cfloop

i've problem to create var with two var

i try to create

var1 = 0
var2 = 0
vars = var1 var2

vars = 00

bcoz php using dot (.) to combine an i try use cfloop for replace the for below. any idea?



CFM:
<cfset left_pad = 0>
<cfset i = len(next_category_id)>
<cfloop condition = "i LESS THAN sibling_length">
<cfset i = i + 1>
<cfset a_pad = insert(0,left_pad,1)>
</cfloop>

if you would explain what you are trying to do, i'm sure there will be a simpler way to do it than looping

as for the actual syntax, what you are looking for is concatenation

php uses a dot, coldfusion uses the ampersand

<cfset concat = foo & bar >

I am also confused. Is this what you are trying to do?

<cfset var1 = 0>
<cfset var2 = 0>
<cfset vars = var1 & var2>

Yeah right! Using &! It'z work!

Anybody can make this code very simple than this? I think it too long

<cfset i = len(next_category_id)>
<cfloop condition = "i LESS THAN sibling_length">
<cfset i = i + 1>
<cfif IsDefined("left_pad")>
<cfset left_pad = 0 & left_pad>
<cfelse>
<cfset left_pad = "0">
</cfif>
</cfloop>
<cfset next_category_id = left_pad & next_category_id>

I'm not sure what you are trying to do, especially as you are referencing variables like sibling_length and left_pad that I have no idea where they came from, how they are set, or what they contain. Can you write out what you are trying to do, or show an example of what the output is supposed to look like?

thanks for the reply, anyway i try combine the variable to make an id.

<!--- Set by default --->
sibling_length = 3

<!--- from agrument --->
next_category_id = 000 or XXX or can be xxxnnnzzz

and the result for next category id

next_category_id = 00N or 00N00N

Well it seems to me that if you want to give the system a number, like 3, and then have it spit out an "id" like XXX, you could do something like:

<cfset lengthOfID = 3 />
<cfset ID = "" />
<cfloop index="i" from="1" to="#lengthOfID#">
<cfset ID = ID & "X" />
</cfloop>

At the end, ID would be "XXX".

wow great! it'z work

thanks kiteless!

<cfset lengthOfID = 3 >
<cfset ID = Left('XXXXXXXXXXXXXXXXXXXXXXXXXX',LengthofID)>

when did the slash to "close" a CFSET tag become popular?

maybe they should call it xCFML
