CFLOOP Help

[bfinelsen]

I have a simple loop

<cfloop list="#prodDetails.matchProds#" index="matching" delimiters=",">
<cfoutput>
<a href="/catalog/?ProductID=#matching#&Category=#URL.category#"> #matching#</a><br />
</cfoutput>
</cfloop>

That currents displays results as:

Value 1
Value 2
Value 3
etc...

I am trying to figure out how to make the out appear as such:

Value 1 Value 2
Value 3 Value 4
Value 5 etc...

Any help here would be much appreciated. Regards.

You need a conditional <cfif> block around the <br/> tag.

The condition for this if block needs to be true when you want the <br/>
displayed and when it is not.

If you want to and only two elements between each <br/> tag, you could
get by with a boolean that is flipped back and forth.

If you want more flexibility where you can have different numbers of
element between the <br/> tags, use a counter and the MOD operator.

Is that enough help?

Something like this?

<cfloop list="#prodDetails.matchProds#" index="matching" delimiters=",">
<cfoutput>
<cfif matching MOD 2 EQ 0>
<a href="/catalog/?ProductID=#matching#&Category=#URL.category#"> #matching#</a><br />
<cfelse>
<a href="/catalog/?ProductID=#matching#&Category=#URL.category#"> #matching#</a>&nbsp
</cfif>
</cfoutput>
</cfloop>

Somewhat, except that I would just put the <cfif> block around the <br/>
tag, not the entire <a...> tag that is the same in both clauses.

But <cfif matching MOD 2> does not work in this case. Since this is a
list loop 'matching' is going to be a string containing each element in
the list.

One would need to either create an independent counter to be used in the
MOD clause or use a listFind() function to get the numeric position from
the list from which the string in 'matching' came.

Thank you! Using your suggestion, I have used a boolean type of syntax to make it work perfectly. Many thanks.

To make that code more efficient, put the loop inside the cfoutput instead of the way you have it now.
