Hello,

I’m creating button using acf link field and showing that with shortcode on my website.
I use this for products description and I want to show message to the user if link filed is empty, something like “No available downloads for this product”.

This is my code:

function notna_slika_link() { 

	$link = get_field('prikaz_notne_slike');
	if( $link );
		$link_url = $link['url'];
		$link_title = $link['title'];
		$link_target = $link['target'] ? $link['target'] : '_self';
	
	return
	
	'<div class="pdf-btn-out">
		<div class="pdf-btn">
			<div class="pdf-inner">		
	
	<a href="' . $link['url'] .'" target="' . $link['target'] .'">' . $link['title'] .'</a>
	
			</div>
		</div>
	</div>'
	
	;
	
}

add_shortcode( 'notna_slika_btn', 'notna_slika_link' );

					</div>
				</div>
			</div>'
			
			;
	} else {
		/// return what you want if no link is entered
	}
	
}
