I have the following snippet code hooked up to a FormIt email form:
$tv = "taken" . (int)$hook->getValue('datetime');
$docID = $modx->resource->get('id'); //get the page id
$page = $modx->getObject('modResource', $docID);
$current = (int)$page->getTVValue($tv);
if (!$page->setTVValue($tv, $current + 1)) {
$modx->log(xPDO::LOG_LEVEL_ERROR, 'There was a problem saving your TV...');
}
$modx->setPlaceholder('successMessage','<h2 class="success">'.$current.'</h2>');
return true;`
It increments a template variable every time it is run and outputs a success message (although right now I'm using that functionality to output a debug message instead). The problem is, it only increments the TV once after saving the snippet, thereby refreshing the cache. Normally I would call the snippet without cache by appending ! to its name, but that doesn't appear to work for FormIt hooks. How can I get this code to work? Right now I'm running the entire page as uncacheable, but that is obviously suboptimal. Perhaps, there's a way to hook a snippet in an uncached manner? Call a snippet from within a snippet as uncached?
