Tesisleri databaseden çekiyorum (dosyanın en başında)

mysql_select_db($database_Veritabani, $Veritabani);
$query_tesisler = "SELECT TesisAdi, TesisFoto, TesisKoordinat FROM tesisler";
$tesisler = mysql_query($query_tesisler, $Veritabani) or die(mysql_error());
$row_tesisler = mysql_fetch_assoc($tesisler);
$totalRows_tesisler = mysql_num_rows($tesisler);
