CacheClear Snippet Tutorial

If you use this extra and like it, please consider donating. The suggested donation for this extra is $5.00, but any amount you want to give is fine (really). For a one-time donation of $50.00 you can use all of my non-premium extras with a clear conscience.

CacheClear is an extra for MODX Revolution that deletes all files in the MODX core/cache directory. It is for people who may not have shell or FTP access to a site or who want a fast and convenient way to completely empty the cache in the MODX Manager. I use it often while developing extras.

Installing CacheClear

Go to System | Package Management on the main menu in the MODX Manager and click on the "Download Extras" button. That will take you to the Revolution Repository. Put CacheClear in the search box and press Enter. Click on the "Download" button, and when the download is finished, click on the "Back to Package Manager" button. That should bring you back to your Package Management grid. Click on the "Install" button next to CacheClear in the grid. The CacheClear package should now be installed.


To use CacheClear, just view the CacheClear Resource. You should see a progress report indicating the cache subdirectories that are being removed.

Note that if you look at the cache on the Files tab in the Manager, it may appear that some of the files have not been deleted because MODX regenerates the directories almost immediately. ClearCache tests for the removal of each directory and will report any failures. If you don't see any failure messages when CacheClear runs, you can assume that it deleted all the directories and files in the cache.


My book, MODX: The Official Guide - Digital Edition is now available here. The paper version of the book may still be available from Amazon.
