Here's an easy one: Doing 'case' with output modifiers

Hi,

what is the best way to produce a certain output depending on the value of a tv, when the possible values are known? Like, think of a single-choice dropdown TV that lets you choose the slider version.

For option 'Nivo', you want to insert a bit of js in the header, and a certain chunk in the body.
For option 'Cycle', you want to insert some other js, and some other chunk.
And for option 'None', you want to insert nothing in both places.

What's the most elegant way to do that? [ed. note: neo2.0 last edited this post 12 years, 7 months ago.]

Write a Snippet with that logic?

I suppose there's no simple way to do it exclusively with output modifiers and without new snippets?

I don't know any php. Yet, at least.

I'm wondering if you could do a code block something like so. Horribly inefficient because it processes every tag regardless of logic, but absent PHP coding you have to work with output filters however creatively you can. You may need to prepend a question mark to prevent caching: [[!*MyTv....

Yeah, that's in the ballpark of what I have been achieving, even though this exact solution has been escaping me.

I guess that it would be quite a snap for a true PHPero to squeeze that into a few lines, wouldn't it?

I'd love to know how that looks in PHP. Would help me to come up with something of my own next time around.

I'm not sure if this will work. You can try this:

If your options are Nivo||Cycle||None
create chunks headNivo,headCycle,headNone and bodyNivo,bodyCycle,bodyNone

and call it with or

if this doesn't work this should:

snippet 'showchunk':

Cool, that looks like what I imagined

Thanks! I am going to try that out tomorrow, will be fun.
I'll tell you how it went.

Well, what can I say:
It just works! My first custom snippet

So cool, I'm sold on PHP

Bruno17, that is really slick. I never knew you could call chunks with a dynamic name like that. I suppose that would apply for any MODx tag? Such a unique feature, that should really be in the docs.
