All of you who use WordPress together with Autoptimize Plugin will know the problem: The add-on does not automatically delete Cached files, and must be done manually.
Especially if you have the "Aggregate inline JS" and "Aggregate inline CSS" functions enabled, the amount of data collected in the cache files storage folder is huge.
So the manager is forced to manually delete those files.
Below we will see some lines code which if added to the theme's functions.php which usesthey will do the whole thing work for you.
We quote the code we use in SecNews, through WPress.gr. It is configured to delete the cached files when the 512MB volume reaches.
//* Clear autooptimize cache at 512MB iGuRu.gr if (class_exists('autoptimizeCache')) { $iguruMaxSize = 512000; $statArr=autoptimizeCache::stats(); $cacheSize=round($statArr[1]/1024); if ($cacheSize>$iguruMaxSize){ autoptimizeCache::clearall(); header("refresh: 0 ");}}
Of course you can change the value in $ iguruMaxSize to 1024MB if you do not want to burden your sites with ongoing php queries.
If you want to change the size, convert 1024MB to KB aka: 1024000.
That's it! The next time you will not need to manually delete the cahced files. At the end of the code as you see there is also a refresh in the header.
