wp_suspend_cache_addition( bool $suspend = null )

Temporarily suspend cache additions.

Description

Stops more data being added to the cache, but still allows cache retrieval. This is useful for actions, such as imports, when a lot of data would otherwise be almost uselessly added to the cache.

Suspension lasts for a single page load at most. Remember to call this function again if you wish to re-enable cache adds earlier.

Parameters

$suspend

(bool) (Optional) Suspends additions if true, re-enables them if false.

Default value: null

Return

(bool) The current suspend setting

	return $_suspend;
}
