vc_mapper_init_before

Fires before the WPBakery mapper begins initialization. This hook runs at the very start of Vc_Mapper::init(), before parameter definitions are loaded and before any element mapping takes place. Use it to prepare resources or register activities that should be queued before the mapping process.

Parameters

This action has no parameters.

Usage

add_action( 'vc_mapper_init_before', 'wpb_before_mapper_init' );

function wpb_before_mapper_init() {
    // Prepare custom configurations before element mapping begins
    // This runs before lean-map.php is loaded
    define( 'MY_PLUGIN_ELEMENTS_LOADED', true );
}
