Newbe with php - javascript problem

[Ralf Meuser]

Hi there

I'm trying to create a button which will exit my php-session un go to my
main page.
I thought of some thing like this:

....
<script language=JavaSc ript>
function fonct_form(form )
{
<?php session_unregis ter( "uid" );
session_unregis ter( "lang" );
session_destroy ();
session_start() ;
?>
document.locati on.href="http://www.mysite.com" ;
}
.....
<TD><input type='button' onClick='fonc_f orm(this.form)'
value='quit'></TD></TR>
......


But this doesn't work.
Thanks in advance for any help

Won't work because php is server-side and your button click is
client-size.

The easiest way would probably be an unregister.php script which is
called when your button is pushed and then redirects to your home page.

There is also another way. You could actually have javascript load an
image into the page such like an image that executes the logout script.

Ouch, you can't put PHP inside of javascript. Javascript is executing in
the browser, and PHP on the web server. Perhaps this would be the idea:

The page has this somewhere:

<TD>
<a href="logout.ph p">Logout Now</a>
<TD>

FILE: logout.php
<?php
session_unregis ter( "uid" );
session_unregis ter( "lang" );
session_destroy ();
session_start() ;
header("Locatio n: http://www.mysite.com" );
?>

Ralf,

I don't know if you figured out your problem or not yet, but you can't
run PHP on the client side like Javascript. PHP is compiled on the
server side. You can use PHP to redirect anyway by using:

header("Locatio n:
http://www.mysite.com" );

You can have a button run that PHP code with the new addition the same
way a submit button would.
