Rent-a-Car Calculator

[sizzla]

Hey people. I need some help on a car hire project am working on. Basically i need to code a simple script in php where there is a drop-down list of cars e.g. Lexus, toyota, Mazda, Ford e.t.c

Each vehicle type has a different price associated with it. There is also an input box for the number of days the client will rent the vehicle. So when a user selects the car type and types the number of days the script (PHP_SELF) will calculate the total price quote for the client.

Additionally, i wanted to include an option of converting the currency type from one to another.

Any feedback will be appreciated. Thanks.

<?php
function makeDropList($name,$list,$selected="") {
  // $name       select name
  // $list       array of value, label pair
  // $selected   selected value
  while(list($value,$label) = each($list)) {
    $options .= '<option value="'.$value.'">'.$label.'</option>';
  }
  $dropList = '<select name="'.$name.'">'.$options.'</select>'."\n";
  $dropList = ereg_replace("value=\"$selected\"","value=\"$selected\" selected",$dropList);
  return $dropList;
} // end function makeDropList($name,$list,$selected="")

$cars = array(
                     ""   => "Select a Car",  

					"500" => "Toyota",
					"100" => "Mazda",
					"200" => "Hyundai",
					"600" => "Lexus",
					"400" => "Ford",
					"700" => "Mercedes",
					"1000" => "BMW"

				);


 $currency = array(   

	                   "" => "Select a Currency",    

	                 "70" => "USD",
                     "90" => "Euro",
                     "120" => "Sterling Pound",
					 "1"   => "KES"					
                               );

$list = makeDropList('car',$cars,$cars);

$list2 = makeDropList('currency',$currency,$currency);

$total     = $car * $days;


     if(!is_numeric($days) or $days <= 0) 
	{ $error = "<p><font color=red>Rent days</font> has to be numeric and greater than zero.</p>";} 
	else {

     if(((empty($days))||(empty($cars))||(empty($currency))))
{

echo 'Sorry, you forgot to fill out some required fields. ';
echo '<a href="javascript:history.back(1)">Try again</a>';

} else {


if(!isset($error) && isset($_GET['action']))
{


	$total     = $car * $days;


}
	else
	{
		$total = '';

}
}
}

$form=<<<FORM
<form method="post" action="$PHP_SELF">

$list<br /><br />
$list2<br /><br />
<input type="text" size="32" name="$days"><br /><br />
$total<br /><br />
<input type="submit" value="Calculate">
</form>
FORM;

print $form;
?>

For this u need to have a main currency lets say your main currency is dollar, and u need to know the conversion rate for the other currencies, something like:

1 $ = 1 $
1 $ = 0.78 EURO
1 $ = 0.45 POUND

After u have the conversion rate its easy to make the currency convertion ...

Thanks bogu, the main currency in this case is KES (Kenyan Shilling)

what is your actual question? Anyhow.. Currency rates you can get from the fx converter at oanda.com

My actual question is how to get the code to work. Right now its just displaying the form content but does not multiply the car rates by the number of days.

You don't seem to get the car or the number of days from anywhere.

You need to get them first fro the posted data array:

$days = $POST['days'];
$car = $POST['car'];
