W3 Total Cache and dynamic code

How do I implement fragment caching?

Edit your templates to with the following syntax to ensure that dynamic features remain so:

• 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 -->

How can I prevent caching directly in my templates etc?

It's possible to empty the entire cache or simply purge the cache of a single post / page:

• Purge the entire page cache: if (function_exists('w3tc_pgcache_flush')) { w3tc_pgcache_flush(); }
• Purge a single post / page by passing it's ID: if (function_exists('w3tc_pgcache_flush_post')) { w3tc_pgcache_flush_post($post_id); }
