Conditional Display of Variables? [solved]

I know I’ve been hitting the forums hard lately, but I’ve been on a big project and I’m learning a WHOLE BUNCH.

Say I have a contact form, and it feeds from keys I made in my context. Like:



But say there is no fax set. Rather than having "Fax:" sitting there looking stupid, is there a way I can do an isset type conditional or something that would not display the whole line if the value is not set?

[[+fax:notempty=`Fax: [[+fax]]`]]
It’s called an output modifier / filter. It’s in the RTFM if you just search for output filter.

Note that you should be using placeholder syntax [[+blah]], and not system setting syntax: [[++blah]]

Thanks. Well see I didn’t know the term to search it. Modx’s renders and filters don’t come natural to me... well anything beyond kindergarden PHP doesn’t sit well with me.

But I try.

It’s good that you ask

MODX is quite easy to get grips on, but like anything you need to know the terminology first.

Did you have a look at the Quick Start? http://modx.com/learn/quickstart/ Not everything’s in there - but the basics of the basics are. I also wrote an article I called "MODX - MOD what?" which is a similar basic introduction: http://www.markhamstra.nl/modx/general/mod-what.html

Near the summer we’ll have two amazing books out (at least: that’s my expectations atm, we’ll see how Bob & Shawn will do :p) which covers everything from start till end. Those will probably become invaluable.


Oh, you could’ve also used the "If" snippet for conditional display, but I personally find output filters easier to use and I *think* they’re faster since they don’t involve calling a snippet, but are built in.
