Description

Whether the current user has a specific capability.

While checking against particular roles in place of a capability is supported in part, this practice is discouraged as it may produce unreliable results. Note: Will always return true if the current user is a super admin, unless specifically denied.

Usage

$bool = current_user_can( $capability );

Parameters

$capability

( string ) required – Capability name.

Returns

bool Whether the current user has the given capability. If $capability is a meta cap and $object_id is passed, whether the current user has the given meta capability for the given object.
