How to disable caching of included PHP file?

  • On my site’s front/home pages I inject some HTML by including a PHP file via a PHP code widget. Is there a way of disabling W3TC caching – not for the home pages – but just for the output of that included file? I tried using:

    <?php
if (function_exists('w3tc_pgcache_flush')) {
w3tc_pgcache_flush();
}
?>

    … in the included file, and flushed the entire cache, but I saw no change – the included file’s output should contain random sequences, but they seem always to be cached from refresh to refresh (until and unless I flush the entire W3TC cache).

    Look at using page fragments, which won’t work with disc enhanced disk caching.

    Example 1: <!-- mfunc any PHP code --><!-- /mfunc -->
    Example 2: <!-- mfunc -->any PHP code<!-- /mfunc -->
    Example 3: <!--MFUNC ? ? ? ? ? --> echo rand(); <!--/mfunc -->
    Example 4: <!-- mclude path/to/file.php --><!-- /mclude -->
    Example 5: <!-- mclude -->path/to/file.php<!-- /mclude -->

    If possible the best practice is to implement a JavaScript-based solution if possible.

    Thanks for replying.

    To work around my problem I unchecked “Cache home page” on the “General” settings. I guess it’s a trade-off between the benefits that brings and having my random content appear.

    I have selected “Disk: Enhanced” under the “Page Cache” setting, simply because the drop-down menu included the advice, “Shared Server (disk enhanced is best)” and I am running on a shared server. Would “Disk:Basic” be comparable (I assume that ‘page fragments’ work with that setting).

    Oh – if I output the random content using javascript, I would avoid the caching issue?
