Show Content only if Countdown is active

What do you mean by PHP content?
Yes, you can use the before and after attributes. Please read the documentation for more info: https://plugins.twinpictures.de/plugins/t-minus-countdown/documentation/
[tminus t="2012-12-20" before="<p>May the force...</p>"/]

Thank you but it seems that div’s doesn’t work.
I need such a code to be displayed only if the code is active.

$votecode = ‘<div class=”ld-container” tid=”‘.$tidcalc.'” buttonclick=”no” userid=’.$userid.’ pageid=’.$pageid.’ action=”https://xxx.de/poll/ajax_likes.php”></div>&#8217;;

But as soon as there is a div class, it doesn’t work anymore when I define

[tminus t=”2012-12-20″ after=”‘.$votecode.'”]

try swapping out your double qoutes (“) for single quotes (‘) and visa-versa…
Also, a link to the page you are having a problem with would be most helpful.

me too need this solution, i need show content if only countdown active, if countdown 0 hide content, have chance this plugin make this? how make this shortcode?

rhcarlos: where do you want to show the content?
above the countdown would be like so:

[tminus t="2013-12-23" before="<p>May the force...</p>" launchtarget="above"] [/tminus]
