/**
 * Adds in better support for FooBox Free and PRO
 */

if ( !class_exists( 'FooGallery_FooBox_Support' ) ) {

	class FooGallery_FooBox_Support {

PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

		function __construct() {

It is generally recommended to explicitly declare the visibility for methods.

			//we need to make sure outdated versions of FooBox never run in the future
			$this->ensure_outdated_foobox_extensions_never_run();

			//add the FooBox lightbox option no matter if using Free or Pro
			add_filter( 'foogallery_gallery_template_field_lightboxes', array($this, 'add_lightbox') );

				//FooBox PRO specific functionality

				//only add FooBox PRO functionality after FooBox version 1.2.29

					add_filter( 'foogallery_attachment_custom_fields', array($this, 'add_panning_fields' ) );

				add_filter( 'foogallery_album_stack_link_class_name', array($this, 'album_stack_link_class_name'));

		function ensure_outdated_foobox_extensions_never_run() {

It is generally recommended to explicitly declare the visibility for methods.

			global $foogallery_extensions;

Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

			//backwards compatibility for older versions of the FooBox Free extension class
			if ( class_exists( 'FooGallery_FooBox_Free_Extension' ) ) {
				$foogallery_extensions['foobox-image-lightbox'] = $this;

			if ( class_exists( 'FooGallery_FooBox_Extension' ) ) {
				$foogallery_extensions['foobox'] = $this;
			}
		}

		function add_lightbox($lightboxes) {

It is generally recommended to explicitly declare the visibility for methods.

			$option_text = __( 'FooBox', 'foogallery' );
			if ( !class_exists( 'FooBox' ) && !class_exists( 'fooboxV2' ) ) {
				$option_text .= __( ' (Not installed!)', 'foogallery' );
			}

			$lightboxes['foobox'] = $option_text;
			return $lightboxes;
		}

		function album_stack_link_class_name( $class_name ) {

It is generally recommended to explicitly declare the visibility for methods.

			return str_replace( 'foobox-free', 'foobox', $class_name );

		function add_panning_fields( $fields ) {

It is generally recommended to explicitly declare the visibility for methods.

				'input'       => 'radio',
				'helps'       => __( 'Enable mouse panning for this image in the lightbox.', 'foogallery' ),

					'enabled' => __( 'Enabled', 'foogallery' )
				)

		function add_panning_attributes( $attr, $args, $foogallery_attachment ) {

It is generally recommended to explicitly declare the visibility for methods.

			$foobox_panning = get_post_meta( $foogallery_attachment->ID, '_foobox_panning', true );

			if ( !empty( $foobox_panning ) ) {
				//add data-overflow="true" + data-proportion="false" attributes to the anchor link
