:wtf:

i have been trying to make this work for days, this needs to also include a discount for staying over >=5 days in Tokyo, no matter what i do i always gets syntax error this class is making me crazy how do i go about getting the discount in this????? please help

<?php

$destination = $_POST['destination'];

$numTravelers = $_POST['numTravelers'];

$numNights = $_POST['numNights'];

$airFare = $_POST['airFare'];

$hotel = $_POST['hotel'];

 

if ($destination == Barcelona)

{$airFare = 875.00;

$perNight = 85.00;}

elseif ($destination == Cairo)

{$airFare= 950.00;

$perNight = 98.00;}

elseif ($destination == Rome)

{$airFare = 875.00;

$perNight = 110.00;}

elseif ($destination == Santiago)

{$airFare = 820.00;

$perNight = 85.00;}

elseif ($destination == Tokyo)

{$airFare = 1575.00;

$perNight = 240.00;}

this is where i can not figure out how to put in the discount off the airfare for staying over five days

elseif ($destination == Tokyo && $numNights >=5)

$tickets = $numTravelers * $airFare;

$hotel = $numTravelers * $numNights * $perNight;

$totalCost = $tickets + $hotel;

 

print("<p>Destination: $destination<br />");

print("Number of people: $numTravelers<br />");

print("Number of nights: $numNights<br />");

print("Airline Tickets: $".number_format($tickets, 2)."<br />");

print("Hotel Charges: $".number_format($hotel, 2)."</p>");

print("<p><strong>TOTAL COST: $".number_format($totalCost, 2)."</strong></p>");

?>

First of all, wrap your strings in double or single quotes. That's probably causing the syntax error.

 

Second, your logic needs some work. An elseif only matches if a previous if/elseif hasn't already been true. In other words, because $destination == "Tokyo" is true, your elseif($destination == "Tokyo" && $numNights >= 5) will never happen. Instead do something like:

	elseif ($destination == "Tokyo")
{
	 $airFare = 1575.00;
	 $perNight = 240.00;
	 if($numNights >= 5)
	 {
		$airFare -= 200; //discount
	 }
}

how about this?

<?php
//i like creating arrays to keep things clearner
$Array = array(
"Barcelona" => array("875.00","85.00"),
"Cairo" => array("950.00","98.00"),
"Rome" => array("875.00","110.00"),
"Santiago" => array("820.00","85.00"),
"Tokyo" => array("1575.00","240.00")
);
$destination = $_POST['destination'];
$numTravelers = $_POST['numTravelers'];
$numNights = $_POST['numNights'];
$airFare = $_POST['airFare'];
$hotel = $_POST['hotel'];
$airFare = $Array[$destination][0];
$perNight = $Array[$destination][1];  
$discount = ($destination == "Tokyo" && $numNights >= 5 ? "200" : "0";
//above change discount to whatever you need it to be         
$tickets = $numTravelers * $airFare;
$hotel = $numTravelers * $numNights * $perNight;
$totalCost = $tickets + $hotel + $discount;
//I do not know where u want the discount added, to the totalcost or what
print("<p>Destination: $destination<br />");
print("Number of people: $numTravelers<br />");
print("Number of nights: $numNights<br />");
print("Airline Tickets: $".number_format($tickets, 2)."<br />");
print("Hotel Charges: $".number_format($hotel, 2)."</p>");
print("<p><strong>TOTAL COST: $".number_format($totalCost, 2)."</strong></p>");
