Variable Rules?

[darthmahon]

Hey,

I've got a selection list that lists towns and cities. Now each of these towna and cities is assigned to a certain Area ID.

For example, London is in Area ID 1.

Now how do I get the variable AreaID to change depending on what is selected in the selection box?

Something like;

If SelectionBox=London
     $AreaID=1
else
If SelectionBox=Harrow
     $AreaID=1
else
if SelectionBox=Manchester
     $AreaID=2
else
If SelectionBox=Liverpool
     $AreaID=2
End If

Know what I mean?

I'm thinking the above process could be quite a long one, just wondering if you can make a rule for a group of cities like;

If selectionbox = Manchester OR Liverpool OR Newcastle
     $AreaID=2
Else
If selectionbox = London OR Harrow
     $AreaID=1
End If

I'm not quite sure how to go about this one.

Cheers,
Chris

<?
if ($SelectionBox == "cityone" || $SelectionBox == "citytwo")
{
$AreaID = 1;
}
else if ($SelectionBox == "citythree" || $SelectionBox == "cityfour")
{
$AreaID = 2;
}
else
{
$AreaID = "";
}
?>

is that what you mean

better still save it in a database and query the database to get the area or even have an array of cities

//setup the array, standard bit that's at the top of the script
//or included from another file
$cities = array();
$cities['London'] = array('area' => 1, 'rating' => 1);
$cities['Harrow'] = array('area' => 1, 'rating' => 2);
$cities['Manchester'] = array('area' => 2, 'rating' => 5);
$cities['Liverpool'] = array('area' => 2, 'rating' => 2);

//now that I have my list I can just do this
$AreaID= $cities[$SelectionBox]['area'];
$rating = $cities[$SelectionBox]['rating'];

echo "{$SelectionBox} is in area {$AreaID} and is rated: {$rating}<br>";

Decided to go with Stolzyboy's suggestion as I'm more familiar with that way and it worked an absolute treat =)

Thank you both though =)
