Clearing MODx Cache programatically?

I know this has been asked before, but how do you clear the MODx cache programatically? I’m working on a bash script to copy our production environment to our dev server, and one of the steps in that process is to clear the MODx cache. Can I simply delete a few files via the command line?

I can’t just hit a page in a browser... e.g., this won’t work:


because you have to be logged in... heheh.

Thanks!

Might start looking here. Please report in that thread if it helps you out, as that’s a very cool and interesting bit of code that may have flown under the radar:

Thanks, Ryan. I’m unclear as to whether or not that bit of code does anything beyond removing the *.pagecache.php files in /assets/cache/ -- I can just do rm via a bash script and be done with it, but is there any magic going on when you invoke the MODx clear cache command? Are there secret database entries that are updated, etc.? I did make a post in that thread, but it unfortunately doesn’t look very active.

I learned that you need to update the sitePublishing.idx.php if your staging server has set publish schedules otherwise MODx will not publish them on the scheduled date on the live server. It holds the timestamp for the next scheduled publish date, if no schedule it is 0.

note: I could be wrong about this, I reached my own conclusions on this one.

Cache syncing via MODx rebuilds the sitePublishing.idx.php but also the siteCache.idx.php file - the latter being extremely important. Merely clearing out the pageCache files is not a full cache synchronisation. See this file in your MODx install: /manager/processors/cache_sync.class.processor.php

According to the MODx wiki, you can call:


However, looking at what that code actually does, it’s no different than the ClearCache script -- it removes all of the *.pageCache.php files in assets/cache/ without rebuilding siteCache.idx.php

So, in order to clear the cache, do what the manager does:



This thing works like a charm; I had all kinds of trouble with programmatically-created blog posts not getting picked up by Ditto, and using this function after creating each post did the trick.

I used that function in a snippet; adjust the paths to use elsewhere.

Seems like a MODx bug, no?

Not really, just misinformation in the wiki and a leftover, soon-to-be-deprecated function that should have more appropriately been called $modx->clearPageCache(), as it is meant to simply remove a single page from the cache. Your information on how to do this is correct.

Revo will feature a more robust API with a very flexible cache clearing function, in addition to a wealth of additional caching features.

Just added a note to the $modx->clearCache() page so that other people won’t get off track. I haven’t looked deeply enough into the Evolution core to describe the distinction between the two, other than using synccache does what the Manager does, and $modx->clearCache() doesn’t. I’ll leave it to better minds to elucidate that connection.
