Cambio pagina motore di ricerca

[WebmasterFC]

Ciao!
Cambiando la pagina non mostra i risultati questo script, come mai?
L'errore è sicuramente in search.php magari una sciocchezza ^_^

Grazie


index.php

<form name="search" id="search" action="search.php" method="post">
<input type="text" name="key" id="key" value="" size="30" maxlength="50">

if ($key == "") {
header("Location: ../", true);
exit();
