WP_Site_Health::check_wp_version_check_exists() public WP 5.2.0

Test if wp_version_check is blocked.

It's possible to block updates with the wp_version_check filter, but this can't be checked during an Ajax call, as the filter is never introduced then.

This filter overrides a standard page request if it's made by an admin through the Ajax call with the right query argument to check for this.

{} It's a method of the class: WP_Site_Health{}

No Hooks.

Return

null. Nothing.

Usage

$WP_Site_Health = new WP_Site_Health();
$WP_Site_Health->check_wp_version_check_exists();
