So, to use this plugin, in WP Admin go to Settings -> Post Snippets
Click Add New Snippet
In the title, give it a shortcode name (must be a valid WP slug name), for example:
my-color-link
Check the Shortcode and PHP Code checkboxes.
In the Snippet textarea copy and paste this:
$livit_kategorie = get_field('Kategorie');
$livit_barva = get_field('barva');
$livit_url = get_site_url() . '/fotogalerie-vysledky/';
echo '<strong><span style="color: #c62daa;">Kategorie</span></strong>: <a href="';
echo $livit_url;
echo '?_sfm_Kategorie=';
echo $livit_kategorie;
echo '">';
echo $livit_kategorie;
echo '</a><br /><strong><span style="color: #c62daa;">Barva</span></strong>: <a href="';
echo $livit_url;
echo '?_sfm_barva=';
echo $livit_barva;
echo '">';
echo $livit_barva;
echo '</a>';
There may be errors in that 😉 as I cannot test it here.
Now all you do is place that shortcode where you want those two lines:
[my-color-link]
