[Resolved] Help nesting switches - simple

carbonspace

I need some help with a really simple problem. Using the following code for my geo site, if a user clicks on a state, I only want to correspoding state's cities to be displayed. I want to learn how to do this the right way but I get nothing but errors trying to nest the switch statements. I'm so close, I can taste it. Can anyone help?

<html>
<head>
<title>Site Title</title>
</head>
<body>
<table>
<tr>
<td valign="top">
<a href="<?=$SERVER['PHP_SELF']?>?state=Alabama">Alabama </a> 
<a href="<?=$SERVER['PHP_SELF']?>?state=Alaska">Alaska</a> 
<a href="<?=$_SERVER['PHP_SELF']?>?state=Arizona">Arizona</a> 
</td>

<td valign="top">
<?php
// initialize the variables
$state = !empty($GET['state']) ? $state = $GET['state'] : $state = '';
$city = !empty($GET['city']) ? $city = $GET['city'] : $city = '';

// show content based on state selection
switch($state)
{
case "Alabama" :
print 'Alabama ';
include ('alCityLinks.php');
break;
case "Alaska" :
print 'Alaska ';
include ('akCityLinks.php');
break;
case "Arizona" :
print 'Arizona ';
include ('azCityLinks.php');
break;
default :
break;
}

// show content based on city selection
switch($city)
{
case "Auburn" :
print 'Auburn ';
break;
case "Bessemer" :
print 'Bessemer ';
break;
case "Birmingham" :
print 'Birmingham ';
break;
default :
break;
}
?>
</td>
</tr>
</table>
</body>
</html>

alCityLinks.php
<a href="?city=Auburn">Auburn</a> 
<a href="?city=Bessemer">Bessemer</a> 
<a href="?city=Birmingham">Birmingham</a>

Try using <?php echo $_SERVER['PHP_SELF'] ?>

Short tags may be off.

I got the nesting issue worked out, thanks for the reply, but I just need to make the state menu list disappear when the user is on a state specific page. I'll keep picking at it , but if you have any ideas, they're definitely welcome. Thanks again. d

Instead of the big switch statement, why don't you use and array.

$citylinks = array( 'Alabama'=>'alCityLinks.php' ,
'Alaska'=>'akCityLinks' ....... );

include( $citylinks[$state] );

If you want this

<td valign="top">
<a href="<?=$SERVER['PHP_SELF']?>?state=Alabama">Alabama </a> 
<a href="<?=$SERVER['PHP_SELF']?>?state=Alaska">Alaska</a> 
<a href="<?=$_SERVER['PHP_SELF']?>?state=Arizona">Arizona</a> 
</td>
to dissappear when $state is set, you will have to put it in an if statement.

<?
if( !isset( $_GET['state'] )
{ ?>
<td valign="top">
<a href="<?=$_SERVER['PHP_SELF']?>?state=Alabama">Alabama </a><br>
<a href="<?=$_SERVER['PHP_SELF']?>?state=Alaska">Alaska</a><br>
<a href="<?=$_SERVER['PHP_SELF']?>?state=Arizona">Arizona</a><br>
</td>

<? }

Thanks for your help. I used what you suggested and tweaked it a bit like this:

$state = "";
$city = "";
if (isset ($GET[state]))
{
$state = "&state=" . $GET[state];
}

if (isset ($GET[city]))
{
$city = "&city=" . $GET[city];
}
?>

seems to work just the way I want it to.

Have a great day.
