"If" - problems

Hello.
I would like a part of my html-code will only be shown if a certain TV isn’t empty.
Therefor I installed the "If"-add-on and modified the code example like this:



(I tried with &else=`0`, &else=`empty` and without &else as well)

It doesn’t work and I get out the code part after the TV, like this


Who can help me with that?

Thank you
Dick

With built-in output filters, I’m not sure why there would be a need for an [tt]If[/tt] add-on.

Anyhoo, try this:

[[!If? 
&subject=`[[*name]]` 
&operator=`notempty` 
&then=`<div>my html-code</div>` 
&else=``
]] 

Try



Avoiding the last new-line solved this for me.

If I recall correctly "IF" is actually more efficient on this front.

Thank you for your help.
cyclismo, I tried your solution and it works perfectly!
But as an absolute modx newbie: Where do I get information about this kind of solutions?
How do I know to use instead of using ?

Have a look in the docs here:

Powerful stuff

Thank you, lucas, for your hint.
That answers a lot of my open questions (I hope).
May the next rainy days come...

Try caching that If snippet call.

[[If ..]] instead of [[!If ]]

There’s no need for it to be processing every request if the data wont change before the cache get clears anyway.
