Hi all,
Please excuse me if this question has been asked before, but I am new to php and can't seem to find the answer to my question anywhere.

I am designing a website for my company. The site will have a JQuery accordion menubar across the top and a sidebar menu as well. What I would like to do, using php in order to save myself the trouble of cluttering my html with menu code on every single page on the site, is make it so that when someone clicks on a link in the menubar, the links listed in the sidebar change according to what was clicked. For example, if someone were to click on "About" in the menubar, the sidebar would display different "About"-related hyperlinks ("About Us", "Management", "Our Staff", "Job Opportunities," etc.) and then, if the user then selects "Products and Services" from the top menu, the side menu would change with a list of new links related to that one.

Is this possible, and if so, how do I do this? Any help is appreciated!

Thanks!
Jason

One possible way that comes to mind is the use of an ifrane.
Setup an iframe where the menu is to be.
Using php, have php set the values for the link they clicked.

I do something similar on my site.
When a user clicks on the year, the iframe content changes accordingly.
Not the entire page.

If this should work with server-side PHP, search for “include” and
“template”.

When all you know is jQuery, every problem looks $(olvable).

Jason,

PHP is server side - to execute any PHP code, the client must make a
call to the server. While this can be done using Ajax, it requires
Javascript code on the client as well as PHP code on the server. As
such, I think it's a bit of overkill for what is basically static
information (the same info for the same menu item on each page).

You don't have to have the Javascript code in every page; it can be
included - and you don't even need PHP to do it. Try
comp.lang.javascript for more information.

To do this at the php level implies some sort of reloading of the page,
or at least the sidebar (is it in a separate frame?) when the menu link
is clicked, with the relevant submenu data loaded.

If you want this to happen inside the page without a reload, that's
something you'd want to do client side, and that's not really a php
issue, although you might use an ajax request in the javascript code on
the client to ask the server for the relevant menu links to display.

You mention jquery - the normal suggestion in this case is to go and find
a jquery forum and ask the question there. There are probably other
javascript methods to do this, but they would be equally off topic here,
but perhaps on topic in comp.lang.javascript - however that latter group
is generally dismissive of jquery (and indeed most libraries) and will
probably suggest that you find a more relevant forum.

So, I think that first of all you need to decide whether:

(a) the menu change is going to happen with a page reload
(b) the menu is going to be in a frame and the menu frame will reload
(c) the menu change is going to happen client side using submenu data
provided as part of the initial pageload
(d) the menu change is going to happen client side using submenu data
provided in response to a menu click

Then you will know what data you need to provide, when to provide it,
what stimuli will trigger its provision, and whether you';re going to be
working client side or server side or both.

Once you know what bits you need to do server side in php, come back and
ask here if you need any help with them.

The site will have a JQuery accordion menubar across the top and
a sidebar menu as well.

What I would like to do, using php in order to save myself the
trouble of cluttering my

html with menu code on every single page on the site, is make it
so that when someone

clicks on a link in the menubar, the links listed in the sidebar
change according to what

was clicked. For example, if someone were to click on "About" in
the menubar, the

sidebar would display different "About"-related hyperlinks
("About Us", "Management",

"Our Staff", "Job Opportunities," etc.) and then, if the user
then selects "Products and

Services" from the top menu, the side menu would change with a
list of new links related

to that one.

This is actually fairly easy to do, once you know how to use
AJAX. The click sends a request to a PHP script that generates
the sidebar code and the ajax code on the client side puts it
there. I don't use jquery, but I am sure that jquery includes
routines to do exactly that.

Other people have suggested using AJAX.
Alternatively, you could include all the
options as HTML in your sidebar, but then
make all but one of them invisible using
the CSS {display: none;}. Then, when the
user clicks on a link in the menubar, use
JavaScript to change what HTML is made
visible in the sidebar.

Whichever way you do this, PHP will not do
it. PHP just generates HTML (perhaps in
response to a JavaScript AJAX request).
This is therefore the wrong newsgroup.

the only way you can do it server side is to cause any click to reload
the page, or part of the page from the server.
But invisible divs are cheap enough, if you don't mind using javascript
to handle the context sensitivity, and its a hell of a lot faster.

I do not have an answer to your question as asked, but maybe an alternative:
Why not just use Masterborders for where you need the menues
changed? The click could simply load a new page even though it's
identical or however you want to set it up, but has a different MB with
the NAV menues you want?

Also, I haven't tried it, but isn't there a way to hide and unhide
objects dynamically? That sounds like it might fit the bill.

I'm no guru and I'm sure others will come along with more specific
answers, but ... thought I'd pass along my thoughts.
