ACF Thumbnail Gallery in Oxygen using Swiper

Updated on October 04, 2019.

This members-only tutorial provides the steps to output images uploaded to ACF Pro's Gallery field attached to a CPT in the markup needed for Swiper’s thumbnail gallery on the post type's single pages.

Step 1 (optional)

Use a plugin like CPT UI to create your desired custom post type.

The name of the CPT in this example is property.

Step 2

Install and activate Advanced Custom Fields Pro.

Create a field group having a gallery type field and attach the group to your post type.

The name of the custom field in this example is property_gallery.

Step 3

Let us load Swiper jQuery library on single property entries in the Oxygen editor and on the front end.

Install and activate My Custom Functionality plugin.

Connect to your hosting account using a FTP client and navigate to site's /wp-content/plugins/my-custom-functionality-master directory.

Upload swiper.min.css to plugin's assets/css directory.

Upload swiper.min.js to plugin's assets/js directory.

Edit plugin.php and replace

add_action( 'wp_enqueue_scripts', 'custom_enqueue_files' );
/**
 * Loads <list assets here>.
 */
function custom_enqueue_files() {
	// if this is not the front page, abort.
	// if ( ! is_front_page() ) {
	// 	return;
	// }
	// loads a CSS file in the head.
	// wp_enqueue_style( 'highlightjs-css', plugin_dir_url( __FILE__ ) . 'assets/css/style.css' );
	/**
	 * loads JS files in the footer.
	 */
	// wp_enqueue_script( 'highlightjs', plugin_dir_url( __FILE__ ) . 'assets/js/highlight.pack.js', '', '9.9.0', true );
	// wp_enqueue_script( 'highlightjs-init', plugin_dir_url( __FILE__ ) . 'assets/js/highlight-init.js', '', '1.0.0', true );
}
