Hi. This really is simple, I know how to write it alogrytmically, so:
if ( get_post_meta($post->ID, "podobne", true) exists)
{
echo ('ID, "Zleceniodawca", true); ?>'">podobne
}
no else, if there is no meta "podobne", show nothing.
Please, help me with this, it really is simple but I'm very new in WordPress.
