How does one do this with an output modifier??

if isempty template_variable do not display specific text
aka don't output snippet/chunk text if TV empty??

Would it be

[[*template_variable:notempty=`text to display`]] ??

Ideally I need this to work per-page -- one page might have TV values, another one might not, all the pages use the same TV...

Thank you, Tom [ed. note: TomMLS last edited this post 12 years, 2 months ago.]

This should work, what is the value of the TV?

It seems you might be better off with a Listbox TV with Yes/No options, unless the TV is used for something else.

It's a MIGX template variable containing a list of values: image, alt/title text, description text, for a slideshow.

Don't want people to have to futz around with copy/paste a text thing if I don't have to...

Thank you, Tom

I did

[[*slideshow:notempty=`<div id="myCarousel" class="carousel slide">
<div class="carousel-inner">
[[!getImageList? &tpl=`slideshow` &tvname=`slideshow`]]
</div></div><!-- final carousel div -->`]]

and it seems to work properly -- at least in initial testing, anyway

Will update this thread when I know for sure...

Thank you, Tom

Further testing shows this works...odd thing is that images don't display properly in the MIGX section but they DO display properly in the browser / frontend and that matters!!

Thank you, Tom
