Rene,
Of course this is possible. However, I doubt if it is desirable. The more
visitors to your site the larger the load if you load all the graphics,
because each session would have it's own copy of all the graphics. It would
be better if you checked the page being loaded and passed a list of the
needed graphics needed to a function that would load ONLY those graphics
needed for said page. This is not too very difficult and if run on a PHP
caching server then the overhead is not so bad. The hard part is getting
the JS to work correctly (at least for me. hehe. I suck at JS).
For example. http://clans.acnsnet.com is a package I'm working on that uses
templates to control the layout. Each menu item is stored in an SQL backend
as well as the Template info (location, menu type, state, etc....). I
already have a function to determine what page is active. So finding out
what menu items are visible is simply a matter of comparing the active page
to the array of menu items. I can then determin which images I would need
to load (depending on the template in use). This way I only load the images
that are needed, which saves on load time and memory.
Anyway, have fun.

What you're saying makes sense--that loading ALL the nav button images
for the whole site at once is overkill. In this case, however, it really
isn't, since there are just to 'sets' of nav buttons--the top-level set,
which needs to be preloaded no matter what page the user is on; and the
products subsection set, which SHOULD be preloaded, because every visit
will inevitably visit that section (it is the reason why any visits the
site). I agree that if there were numerous sub-level 'sets' of nav
button images, that loading all of them would be inefficient.

Hello,
I would like to reinitialise an MySQL_fetch_array. That is, once it has gone through I
would like to be able to go back to the start again.
for eg
while ($myrow=MySQL_fetch_array($result2))
{
$befid=$myrow["beforeid"];
while($myrow5=MySQL_fetch_array($result5))
{
$aftid=$myrow["afteridid"];
if ( $befid == aftid)
{
do something;
}
} //while($myrow5=MySQL_fetch_array($result5))
//now that the inner loop has finished I would like to be able to restart the
inner loop by reinitailsing the MySQL_fetch_array
} //while ($myrow=MySQL_fetch_array($result2))
Regards,
Ivan

IT IS NOT POSSIBLE!!!
Php does not permit editing of files on the file system of a remote host. If
you want to edit your php scripts on some free host...then place a dirty
code editor on that system...It may be slow but it is the only solution...
It MIGHT be possible to use the fopen() command and make an editor like
that(your imagination) but you need to set the CHMOD of the files each time
you edit it....But it is a BAD idea....It is going to be slow..You may get
several errors....
If it works...make it a public domain for the advantages of others..

You may want to take a look at the midgard project's
cms API using php4.
http://www.midgard-project.org/
That combined with a web base interface created by hklc.com
called nadmin studio enables you write your entire web site from a browser.
here is a demo of it on hhlc's site.

Ehm ...
I tried to do open_basedir within the .htaccess and own this file by root,
so the user
couldn´t change the settings. But yeah, that wasn´t the best solution, now I
do within
the Apache config file.
A entry for a vhost looks like this:
<VirtualHost IPADRESS>
ServerAdmin [EMAIL PROTECTED]
ServerName www.domain.com
ServerAlias domain.com
DocumentRoot /home/domain/public_html
php_admin_value open_basedir /home/domain
</VirtualHost>
Hope it helps !
Cya !

Hi Yasuo,
I seem to remember having similar problems understanding objects and
references
also and you guided me here. Manuel is a good programmer and if he also has
problems, I'm a bit worried for novices. Objects and references are not
intuitive :(

If there are no other virtual hosts on your box, you could leave Apache as is
(unrecognised hostnames will go to the default site), and do the dynamic
processing in PHP using the $REQUEST_URI variable...
as for the crazy-page.php thing, you could set up a custom error handler page
that points at your dynamic page...
Hope that helps...

HTTP authentication (which is what you're using) is controlled by the
browser. Some browsers even keep the login/password after the window is
closed until the user logs out (Konqueror on Linux for one...)
If you want more control over logins and the ability to do a logout, you
should make your own login scheme using an HTML form for username/password
and setting a cookie to flag that the user is 'logged in'. Then, when the
user wants to log out, clear the cookie and job done :)

Well, I have to second that. If it weren't for PHP I probably would have
never gotten into web development at all. I've said it before and I'll say
it again...if Microsoft solutions were the only ones available I would have
switched careers long ago. Thank God (and the PHP developers) for PHP!
