dosya ise şu şekilde

<?php
ob_start();
include 'baglan.php';

if (isset($_POST['genelayarkaydet'])) {

    $ayarkaydet=$db->prepare("UPDATE ayar SET
ayar_baslik=:baslik,
ayar_harita=:harita,
ayar_foto=:foto,
ayar_gsm=:gsm,
ayar_sabit=:sabit,
ayar_faks=:faks,
ayar_mail=:mail,
ayar_port=:port,
ayar_kmail=kmail,
ayar_sifre=:sifre,
ayar_server=:server
WHERE ayar_id=0");
    $update=$ayarkaydet->execute(array(
        'baslik' => $_POST['ayar_baslik'],
        'harita' => $_POST['ayar_harita'],
        'foto' => $_POST['ayar_foto'],
        'gsm' => $_POST['ayar_gsm'],
        'sabit' => $_POST['ayar_sabit'],
