Thanks a lot for the script. I was trying to debug it. It does switch
to protected mode, it just does not seem to switch back. I am going to
continue to work on this, and keep you posted on the updates. I found
that you can replace crypt('test') with '@_site_edit' and get the
desired result of password protecting a page with the editors
password. It does not however switch back to unprotected mode. Worst
case scenario might be to have two buttons: Protect and Unprotect.
However, in that case editors would have no way of knowing if a page
was protected or not without logging out. It seems like there ought to
be a way to do this.
Like I said, I will continue to work on this, and gladly publish a
cookbook if it works out.
Thanks for the help, and let please keep me posted if you can make any
progress,
Alex

I tried putting this at the bottom of config.php, but it just
seemed to mess
up my pages:
$HandleActions['switchauth'] = 'switchauth'; # if url contains
action=myaction call HandleMyAction timely
$HandleAuth['switchauth'] = ' '; # authorization level
$auth
for HandleMyAction
function switchauth($pagename, $auth) { # parameters
(signature) of
handler function required by PMWiki
# Lock(2);
$pagestuff = RetrieveAuthPage($pagename, 'attr', false);
$old=$pagestuff;
if($pagestuff['protected']==true){
$pagestuff['passwdread'] = 'test';
$pagestuff['protected']=false;
}
else{
$pagestuff['passwdread'] = 'test';
$pagestuff['protected']=true;
}
UpdatePage($pagename, $old, $pagestuff);
Redirect($pagename);
# Lock(0);
}
Can someone please help me?
Try this:
===(snip)===
$HandleActions['switchauth'] = 'switchauth'; # if url contains
action=myaction call HandleMyAction timely
$HandleAuth['switchauth'] = 'attr'; # authorization level
$auth for HandleMyAction
function switchauth($pagename, $auth) { # parameters (signature)
of handler function required by PMWiki
Lock(2);
$pagestuff = RetrieveAuthPage($pagename, 'attr', false);
$old=$pagestuff;
if($pagestuff['protected']=='true'){
// (Ideally we would strip out the exact passwd rather than
blanking
// the whole thing.)
$pagestuff['passwdread'] = ''; // set it to no passwd (loses
any other passwd - sorry)
$pagestuff['protected']='false';
#echo "DEBUG: UNprotecting<br>\n";
} else {
// (Ideally we would append the passwd rather than replacing
what may
// have existed before.)
$pagestuff['passwdread'] = crypt('test');
$pagestuff['protected']='true';
#echo "DEBUG: Protecting<br>\n";
}
UpdatePage($pagename, $old, $pagestuff);
#echo "DEBUG: Updated<br>\n";
Redirect($pagename);
Lock(0);
}
$FmtPV['$protected'] = 'PageIsProtected($pagename,"edit")';
function PageIsProtected($pagename, $level)
{
global $PCache, $PasswdVarAuth, $FmtV;
$page = $PCache[$pagename];
if (!isset($page['=passwd'][$level])) {
$page = RetrieveAuthPage($pagename, 'ALWAYS', false,
READPAGE_CURRENT);
if ($page) PCache($pagename, $page);
}
$protected = @$page['protected']; // either "true" or something else
return ($protected);
}
===(snip)===
Note that if someone sets another password on a page (pmwiki allows
multiple passwords) and then this action is used on that page then the
additional password will be lost. I've referred to that problem in
the comments -- not a big deal to fix, but I don't remember if a space
or something else is the separator between multiple passwords.
Since you've got the convenient $page['protected'] in there I went
ahead and used that to set the {$protected} PV and used it in
Site.PageActions like this (accesskey is pretty non-standard):
===(snip)===
(:if auth attr:)
* %item rel=nofollow class=switchauth accesskey="s"%
[[{*$FullName}?action=switchauth | (:if1 equal {$protected} "true":)
Unprotect (:else1:) Protect (:if1end:) ]]
(:ifend:)
===(snip)===
If this ends up working for you, please publish it as a recipe in the
cookbook -- it seems like something that someone else may be able to
use in various contexts...
