Not cache shortcodes on a post

You could change the Page Cache to Disk: basic and use Fragment Caching to disable page cache for that specific part of code. If you need more details, please ask.

Hi, I’m having an issue with the Fragment Caching too.
I have the “W3TC Pro edition” but I cannot check the Late Initialization option. Not sure if this option is a “must” to run properly any Fragment Caching.

My objective is the avoid caching a shortcode that is launched from the theme “header.php” file. So following the instruction from W3Edge developers I have added the code below:

<!– mfunc mycode –>
<?php echo do_shortcode(‘[responsive_menu_pro]’); ?>
<!– /mfunc mycode –>

Inside the “wp-config.php” file there is the next line:
define(‘W3TC_DYNAMIC_SECURITY’, ‘mycode’);

The result is that the Menu is cached and when 2 different users access to the page, the second one sees the first user dynamic information on it, as the menu has been cached.

Any suggestion? Am I doing something wrong?

Thank you very much.

@iokinpardo Since do_shortcode is a WordPress function, the Late Initialization option is required. If that option is disabled, you might be using Disk: Enhanced, which doesn’t allow Fragment Caching.

Also, your code is missing the second - for HTML comments and it won’t work if you add the PHP open and close tags (that’ll run the PHP code and cache the output, which defeats the purpose of fragment caching). It should be:

<!–- mfunc mycode -–>
echo do_shortcode(‘[responsive_menu_pro]’);
<!–- /mfunc mycode -–>

Hi, I had:

– WP multi-site
– W3TC paid version
– “Late Initialization” enabled
– “Disk: Basic”
– “Browser cache” disabled
– “Minify” disabled
– “mfunc” added to the ‘Ignored comment stems’

Inside my theme’s “header.php” file at the end, this code:
<!–- mfunc FRAGMENT_CACHING -–>
echo do_shortcode(‘[responsive_menu_pro]’);
<!–- /mfunc FRAGMENT_CACHING -–>

Inside the “wp-config.php”:
define(‘W3TC_DYNAMIC_SECURITY’, ‘FRAGMENT_CACHING’);

And the Fragment is being cached all the time.

I have not seen in any site any example of the Fragment cache working.
Any help would be more than appreciated as I have more that 30 sites waiting for their cache.
