Hi,
I am relatively new to php and am currently working on a site where I need
to use a collapsing menu system. I have written the code to do this
however I am completely at a loss to do one particular thing. To best
explain what the problem is I will give you an overview of how the menu
hangs together.
The menu looks like this:
Catagory1 (note these look like buttons)
Catagory2
Catagory3
When a user clicks on a catagory that catagory expands to show the sub
catagories and the menu then looks like this ( assuming they clicked on
catagory1)
Catagory1
subitem1
subitem2
Catagory2
Catagory3
If you were to click on catagory2 then the sub items for that catagory would
appear and the sub items for catagory 1 would disappear.
The menu script I created draws the catagories to look like buttons and
gives them a url in the form of 'index.php?s=#' so for example catagory1
has the url of 'index.php?s=1'
The script draws the first 'button' (catagory1)and proceeds to check to see
if that catagory is active and if so it then populates the subitems and
then loops and draws the next button (catagory2). What I would like to do
is some how when a user click on catagory1 to have the script recognise
this and rather than give the button the url of 'index.php?s=1' when the
page is drawn to simply change it to a text lable, if the user was then to
click on button 2 (catagory2) it then needs to change button 2 url to just
a text lable and button 1 url back to 'index.php?s=1'.
I hope this makes sense, i have included a cut down version of my menu
script which hopefully will make things clearer.
Any help on this will be appreciated.

<?php
session_start();
if ((isset($_SESSION['group'])) && (!isset($_GET['s']))) {
$s = $_SESSION['group'];
}
else {
$s = $_GET[s];
}
//Get current page
$page = $_SERVER['REQUEST_URI'];
// array holds menu button names and passes menu group value
$headers = array('Cars' => 'index.php?s=1','Bikes' => 'index.php?s=2');
$sub_1 = array(
'Sports' => 'sports.php',
'Family' => 'family.php',
'4x4' => 'fourby.php'
);
$sub_2 = array(
'Motocross' => 'moto.php',
'Road' => 'road.php',
'Scooters' => 'scooter.php',
);
// Draw the menu
foreach ( $headers as $key => $value ) {
// Line below draws a button this is the part i want to be able to change
the value of if that submenu is currently active
echo "<div id=\"button\"><a href='$value'>$key</a></div>";
$_SESSION['group'] = $s;
if (($key == "Cars") && ($s == "1")) {
foreach ( $sub_1 as $key => $value ) {
$_SESSION['group'] = $s;
// Check to see if page is active is so bold it
if ($value == $page) {
echo "<b><a href='$value'>$key</a></b>";
}
else {
echo "<a href='$value'>$key</a>";
}
}
}
if (($key == "Bikes") && ($s == "2")) {
$_SESSION['group'] = $s;
foreach ( $sub_2 as $key => $value ) {
$_SESSION['group'] = $s;
// Check to see if page is active is so bold it
if ($value == $page) {
echo "<b><a href='$value'>$key</a></b>";
}
else {
echo "<a href='$value'>$key</a>";
}
}
}
}
?>

Please note I call this script as an include from my template
Many thanks
