Clear cache of a single modx resource

Hi Guys.

I have a CMP that updates some resources. When I update the resource from the CMP, it doesn’t clear the cache.

When I use the regular resourec saving function and the clear cache checkbox is selected, it clears the cache...

$p = $modx->getObject('Productdesc',1);

if($p) {
	$p->fromArray(array(
		'name' => $strProdName,
		'alias' => $strProdName,
		'description' => $strProdDesc,
	));

	if($p->save()==false) {
		echo genMessage("errormsg", $modx->errorCode());
	} else {
	$p->clearCache();
	
	}
}

I am looking for the clearCache() function... does it exists? kinda must....

Thanks for helping me out

Cheers Ragnar

sorry guys for reposting, but I just think that someone must know the answer to my question. Or did I post it in the wrong branch?

Any suggestions to investigate it my self would be appreciated...

Thanks for the hint.

I tried to find the file that gets executed when I click the "save" button on a resource after altering it.
but I didn’t find it.

If I would find that function I might be able to reverse engineer the cache clearing function on on resource...

any help still much appreciated

I believe it would be in these two files:

core/model/modx/processors/resource/create.php
core/model/modx/processors/resource/update.php

The cache file for a particular resource in the web context would normally be:

core/cache/web/resources/#.cache.php

Where # is the ID of the resource, so a plugin could delete that file, but I’m not sure what the side-effects might be.

thanks for the hint. I found a solution to my problem.

So checking out the update.php file, there is a empty cache section...

so if you are working with CMP and you are saving / updateing resources with your individual code. then you can do this to empty the cache of an updated resource.

$resource = $modx->getObject('modResource', $yourResourceID);
$resource->set('pagetitle', $strNewPagetitle);
$resource->set('alias', $strNewAlias);
if($resource->save()) {
	/* empty cache */
	$cacheManager= $modx->getCacheManager();
	$cacheManager->clearCache(array (
			"{$resource->context_key}/resources/",
			"{$resource->context_key}/context.cache.php",
		),
		array(
			'objects' => array('modResource', 'modContext', 'modTemplateVarResource'),
			'publishing' => true
		)
	);
}

Thanks for helping me out here.

cheers ragnar

You can also just call the resource/update processor and let it do the work for you.
