I believe I do what you are attempting to do, in pure PHP using a switch
statement and variables. It works, (check www.northpointless.org to see it
in action) but keep in mind my site is in early developement, so the menu
options aren't quite fleshed out at this time.:
function menu ($pos, $sub = none, $sub2 = none) {
global $PHP_SELF;
global $sess_auth;
switch($pos) {
case main:
print BA HREF=$PHP_SELFHome/A;
print BRA
HREF=$PHP_SELF?sub=Commaction=CommCommunity/A;
print BRA HREF=$PHP_SELF?sub=JFFaction=JFFAfter
Hours/A;
print /B;
break;
case secondary:
switch($sub2) {
case WOS:
$wos = FONT SIZE=-1BAdd Slander/FONT;
break;
}
switch($sub) {
case Comm:
print BMessage Boards;
print BRMailing List;
print BRJob Listings;
print BRMember Directory;
print /B;
break;
case JFF:
print BA
HREF=$PHP_SELF?action=wosaction_args=showsub=JFFsub2=WOSWall Of
Slander/B/A;
if ($wos) { print BR$wos; };
break;
}
break;
}
}

See my response to Girish' post.
You can't have JavaScript talking to PHP in real-time for
user-interaction.
You either need to send your ENTIRE tree to JavaScript, or make the user
choose on each page from a sub-menu...
For that, you would just need to have JavaScript set the location to
something involving the ID of the sub-category so PHP can then generate a
new menu.

Subject: Hierarchic menus using Javascript and PHP?
On my site I have a page that takes input into a MySQL database
(though this isn't a db question).
Each entry has a category and a subcategory entry, which should come
from predefined lists and are therefore instituted as pull-down
lists. The category list is in a PHP array which feeds a SELECT
pull-down list. The subcategory choices should depend upon what
category is selected. In order to ease user input, I've used a
javascript function to cause the subcategory pulldown to depend upon
the category selection. Thus if the category is Animals, the
subcategory SELECT would show dog, cat, fish - but if the
category were Colors the possible subcategories might be Red,
Green, Yellow, Puce.
On the initial entry - a blank record - this all works fine. But if
I go back in to modify a record I run into trouble, as I can't make
the page reflect the stored value of the subcategory within the
pull-down list (i.e. as the SELECTED item).
I use the following PHP code to display the $categories array - and
if there is a stored value ( $formValues[category] ) it displays
that selection as SELECTED - which is exactly right.
printf(TRTDCategory /TD);
printf(TDSELECT NAME=category ONCHANGE=\updateCats()\\n);
printf(OPTION VALUE=0 === Select One === /OPTION\n);
$i=0;
while ($i count($categories)) {
printf(OPTION VALUE=%s %s%s/OPTION\n,
$categories[$i],
$categories[$i] == $formValues[category] ? SELECTED : ,
$categories[$i]);
$i++;
}
printf(/SELECT/TD/TR);
But when it comes to the Sub-Category the list that feeds the SELECT
list is not in an array, but is coming from the JavaScript function
like:
if(subCategoryIndex == 1) // Colors
document.search.subcategory.options[1] = new Option('Red');
document.search.subcategory.options[1].value = red;
document.search.subcategory.options[2] = new Option('Blue');
document.search.subcategory.options[2].value = blue;
...etc...
I can't figure a way to make the 'Update' version of the page display
the value of the Sub-Category in a select list (so that the user CAN
update it). I can certainly have the value display, but it no long
has the other possible members of the list, since it's not coming
from a display.
I couldn't see a way to do this (updating one form element from
another) completely in PHP - else I would have.
Does anyone have any ideas?
Could I feed a PHP array FROM JavaScript? If I could get the
subcategory selection list into an arry I think I could make this
work.
Or possibly use another
