Hi, I’m using Revolution (latest release).

I’ve assigned a TV to my template, but in my template I wrap a div around it. with some margin/border etc.

<div id="foo">
[[*mytemplatevar]]
</div>

How can I adjust my TV to only show the wrapping DIV if the TV has been set?

The TV is an image. presumably I would put it in a chunk with some input/output filtering? but i couldn’t see an "isset" type function.

so in pseudo ~

if(isset($myTV)) { 
 return '<div id="foo"> . $myTV . '</div';
} else 
 // return nothing
}
thanks in advance.

For Revo you can use IF

Adapt this code to be used with IF

Or you can use an output modifier

[[!*myTV:is=``:then=``:else=`<div id='foo'>[[*myTV]]</div>` ]]

Cheers

Hello,

one shorter way with output modifier would be

[[*myTv:notempty=`<div>[[*myTv]]</div>`]]

Those modifiers are really nice, aren’t they ? wink

Yep indeed very nice...

BTW I gave an "extended" version in the case ross needed a "if else" routine wink

cheers
