According to ACF documentation, a foreach
loop is to be used to access the items in a Relationship field.
Untested:
$templates = get_field( 'field_61318c078a746' );
foreach ( $templates as $template ) {
$template_image_id = absint( get_field( 'Image', $template ) );
$template_image_url="https://example.com/fallback-image.jpg";
if ( ! empty( $template_image_id ) ) {
$template_image_url = wp_get_attachment_image_url( $template_image_id, 'large' );
}
...
}
In most use cases you will not need to interact with field groups on the frontend. There are occasions for it, but very few in my experience.
