Crikey, it looks terribly complicated for what looks like something to page
through a set of results.
Wouldn't it be easier to do away with the ereg_replace()?
if($go=="next") {
if($page < $nr_pages && $page >= 0) {
$page++;
$start = $page * 20;
}
}
$qry = "SELECT
L.Tunnus,N.Nimi,L.ISSN,L.Vuosi,L.Lisätietoja,L.Vuosikerta,L.Numerot,L.Huom
autuksia FROM uusi_lehtitaulu L, nimet N
WHERE (L.Nimi_id=N.id AND N.Nimi LIKE "asdf")
LIMIT $start,20"
Even it this doesn't work, at least it's easier to understand :)
