🚄 Cache WordPress post content, template part, translations and nav menu output in persistent object cache
Cache post content, translations and nav menu output in persistent object cache.
This MU plugin works well in production providing you understand its source code (133 sloc).
Please see https://github.com/szepeviktor/wordpress-website-lifecycle/blob/master/WordPress-performance.md
Of course you need persistent object cache. Consider Redis server and wp-redis
plugin.
Replace the_content()
calls in your theme.
NOTICE Replace only argument-less calls! $more_link_text
and $strip_teaser
are not supported.
find -type f -name "*.php" | xargs -r -L 1 sed -i -e 's|\bthe_content();|the_content_cached();|g'
wp_suspend_cache_addition( true );
define( 'DONOTCACHEPAGE', true );
Protection against plugin deactivation.
Copy these to your theme's functions.php.
if ( ! function_exists( 'the_content_cached' ) ) {
function the_content_cached( $more_link_text = null, $strip_teaser = false ) {
the_content( $more_link_text, $strip_teaser );
}
}
if ( ! function_exists( 'get_the_content_cached' ) ) {
function get_the_content_cached( $more_link_text = null, $strip_teaser = false ) {
return get_the_content( $more_link_text, $strip_teaser );
}
}
if ( ! function_exists( 'get_template_part_cached' ) ) {
function get_template_part_cached( $slug, $name = null, $version_hash = '' ) {
get_template_part( $slug, $name );
}
}
