include "connect.php";

$date = $_GET["date"];

$origin = $_GET["origin"];;

$destination = $_GET["destination"];



$query = "SELECT * FROM tbl_flight  WHERE origin=:origin AND destination=:destination AND

 date=:date ";

$res = $conn->prepare($query);

$res->bindParam(":origin", $origin);

$res->bindParam(":destination", $destination);

$res->bindParam(":date", $date);

$res->execute();

$tickets = array();

while ($row = $res->fetch(PDO::FETCH_ASSOC)) {

    $record = array();

$record["id"] = $row["id"];

$record["origin"] = $row["origin"];

$record["destination"] = $row["destination"];

$record["airport_origin"] = $row["airport_origin"];

$record["airport_destination"] = $row["airport_destination"];

$record["date"] = $row["date"];

$record["type"] = $row["type"];

$record["kind"] = $row["kind"];

$record["company"] = $row["company"];

$record["flight_time"] = $row["flight_time"];

$record["land_time"] = $row["land_time"];

$record["capacity"] = $row["capacity"];

$record["flight_id"] = $row["flight_id"];

$record["price_young"] = number_format($row["price_young"]) . " ریال";

$record["price_child"] = number_format($row["price_child"]) . " ریال";

$record["price_baby"] = number_format($row["price_baby"]) . " ریال";



$tickets[] = $record;

}

echo JSON_encode($tickets);
