WordPress Feature Flags

In template usage:

if ( \WPFeatureFlags\Utils::is_feature_enabled('new_header') ) { // Output new code }

Target specific user:

$user_id = 5; if ( \WPFeatureFlags\Utils::is_feature_enabled('new_header', $user_id) ) { // Run new header code for user #5 }

JavaScript usage:

// Check if a feature is enabled if (WPFeatureFlags.isFeatureEnabled('new_header')) { // Run new header code $('#site-header').addClass('new-design'); } else { // Run old header code $('#site-header').addClass('classic-design'); }
