Filter option_active_plugins
. You can change the result of get_option()
here without actually changing the database.
if ( defined( 'DOING_AJAX' ) && DOING_AJAX )
add_filter( 'option_active_plugins', 'disable_plugins_temporary' );
function disable_plugins_temporary( $plugins )
{
// unset plugins you don't need, then
return $plugins;
}
Background
wp_get_active_and_valid_plugins()
calls get_option( 'active_plugins', array() )
to get the active plugins. In get_option( $option, $default = false )
we find this filter:
return apply_filters( 'option_' . $option, maybe_unserialize( $value ) );
So the resulting name for our filter is option_active_plugins
.
