Acf image gallery

Hello,
Array fields are not supported. The field needs to return a string in order to sent to Telegram.

You can use some custom code to ensure that a string value is returned.

Here is an example that uses the first image of the gallery in place of a featured image

/* WP Telegram - use first image from ACF gallery */
add_filter( 'wptelegram_p2tg_featured_image_source', function ( $url, $post ) {

	$images = get_field( 'model_gallery' );

	if ( ! empty( $images ) ) {
		$first_image = reset( $images );

		$url = is_array( $first_image ) ? $first_image['url'] : wp_get_attachment_url( $first_image );
	};

	return $url;
}, 10, 2 );
/* WP Telegram - use first image from ACF gallery */
