Storing option value as variable from dropdown without submit

[jamiejones82]

Hopefully someone can help, firstly i am a newbie at php coding but keen to learn more.

 

Here is my problem 

 

The database is built correctly with all the information i need, the first part is the dropdown menu which you select a car, next you choose a month and mileage - from there it shall show you the correct price for each one. There is columns for each price, mileage and months i just need to figure out how best to start this thing.

 

I first started by this

 

$query = "SELECT DISTINCT Full_Description FROM import"; 

$result = mysql_query($query) or die(mysql_error());

 

echo "<select name=\"carname\">";

echo '<option value="">Please select...</option>';

while($row = mysql_fetch_array($result))

echo "<option value='{$row['id']}'>{$row['Full_Description']}</option>";

 

echo "</select>";

 

$carids = $_POST["carname"];

$_SESSION["carid"] = $package_id;

echo $_SESSION["carid"];

 

$query2 = "SELECT Mileage FROM import WHERE id = '$carnames22'";

$resultsdsd = mysql_query($query2) or die(mysql_error());

 

?>

 

This got me all the cars listed in a dropdown select, but it did not store the selected car id for me to use else where, i am not even sure if this is the best approach.

 

Please can some help me!

$query = "SELECT DISTINCT Full_Description FROM import";

 

 

You do not select the id column so $row['id'] does not exist
