count_down: A Small Countdown Snippet Pattern for Evolution CMS

Small presentation snippets often solve very practical editorial needs, and countdown logic is a good example. The donor post adapted a Revo-style idea into a simple Evolution CMS snippet that reads a target date, calculates the remaining interval, and prints a frontend-ready counter wrapper.

Core idea

$resource = $modx->getObject('modResource', 37);
$date_end = $resource->get('unpub_date');

$datetime1 = new DateTime('now');
$datetime2 = new DateTime($date_end);
$interval = $datetime1->diff($datetime2);
$time_left = $interval->format('%d %H:%i:%s');

The snippet then wraps the result in markup that a frontend timer script can animate.

This kind of helper is useful because it shows how little code is needed to bridge resource data and presentational JavaScript when the requirement is narrow and clear.
