Hi,

This is my first time using php in my site navigation, I have the code
for all the pages in one file and I am using the switch statement to
change between them.

This is working great but I am now trying to change the css id of the
current page's navbar link. How do I get my script to recognize which
case is currently being echoed by the switch statement?

If you want to see the page in action without php in the navbar visit
here: http://www.publikdesign.com

Here is the code:

Contact a>

"; }
?>

if ( $page = "portfolio" ) {
echo "

"; }

else {
echo "

\">Portfolio

switch($_GET['page']) {

case "contact":
echo "

Phone 0437 988 399

eMail \">tdaff@publikdesign.com

";
break;

case "portfolio":
echo "

alt=\"Portfolio\" />

$\"K$ Development Lofo\" />

\">Click to Expand

\"Katmandog Logo\" />

\" target=\"_blank\">Click to visit website

\"Island Healing Logo\" />

Click
to Expand

\"Roaming Earth Logo\" />

Click
to Expand

";
break;

case "home":
echo "

$page = case; will be raising a notice which you're obviously not
seeing. So, step 1 is to edit PHP.ini on your development machine so
error_reporting is E_ALL, and display_errors is on. You'll need to
restart your web server for this change to take effect.

The case keyword is not valid outside a switch block. What you want to
be doing is comparing "contact" etc with $_GET['page'] which is the
variable the switch statement is using.

Additionally you are using a single = which is the assignment
operator, so each if statement is assigning the quoted string to $page
not testing for it. You need to use == to do that.

I would suggest you buy a book on PHP for beginners, or Google for an
introductory tutorial because these are pretty basic syntax mistakes.

Quite sure this is not what you mean:

> $page = case;
> if ( $page = "contact" ) {

but instead

> $page = case;
> if ( $page == "contact" ) {

None of your code included a case/switch piece. This is probably
what you mean:

$page = basename($_SERVER['PHP_SELF']);

switch($page) {
case "contact.php":
$css = "

";
break;
case "portfolio.php":
$css = "

";
break;
case "whoweare.php":
$css = "

";
break;
default:
$css = "

";
break;
}
?>
