How to change a number based on what someone chooses?
Posted: Sat Aug 18, 2012 4:35 pm
In the below URL if a person chooses "whatever" or "whatever2" how would I get the price to adjust upwards or downwards based on what they choose? Would that be related to a mysql statement? Thanks man!
For example, if they choose "whatever" the price goes up for 100 or "whatever2" the price goes down by 100
I added a if statement (below) and I can't seem to get it working. I've been playing around with this the past few hours and can't seem to get it working. Any pointers? Thanks everyone!

<?php
//Connect to the database through our include
include "connect_to_mysql.php";
// Query member data from the database and ready it for display
$sql = mysql_query("SELECT * FROM car_data2");
while($row = mysql_fetch_array($sql)){
$price = $row["price"];
}
?>
<?php
$priceMods = array ('whatever' => 100, 'whatever2' => -100);
if (isset ($priceMods[$_POST['choose']]) {
$price += $priceMods[$_POST['choose']];
}
?>
