We finally managed to come up with a first tiny recipe here. I must
say we're very proud .-)
I have attached our cookbook recipe here. It's working well but I'd be
very happy if anyone could please review and comment on it to see if
we have build in some major bugs or weaknesses for future releases or
whatever ...
Thanks to everyone who contributed!

// Description:
We got pmwiki-2.2.0-beta65 running with LDAP authentication and want
only authenticated users to be able to edit pages. Therefore we set
the following in config.php:
$DefaultPasswords['edit'] = 'id:*';
Now we'd like to add a checkbox "This is a public page" to the edit
form that does the following: If unchecked (default), the read
password for the page being edited should be set to "id:*" allowing
only authenticated users to VIEW the page. If the author activates
the
checkbox, the read password should be cleared so anyone can see the
page.
// Precondition:
- You must add an extra checkbox into the Site.EditForm a la
(:input e_public:) Allow unauthorized users to view this page?
// Known issues:
- When setting the password, the page is shown afterwards without
password
prompt. For our purpose, this is not crucial as we only allow
authenticated
users to edit pages and therefore they can see the page
afterwards anyway.
*/
// Prepend "CheckPassword" function at the BEGINNING of the
$EditFunctions array
array_unshift($EditFunctions, 'CheckPassword');
// Insert "AllowPublicPage" function immediately before "PostPage"
array_splice($EditFunctions, array_search('PostPage', $EditFunctions),
0, 'AllowPublicPage');
// Prepend the extra input field at the BEGINNING of the $EditFields
array
array_unshift($EditFields, 'public');
/* /////////////////////////////////////////
CheckPassword()
- get current page read password(s)
- if checkbox "public" is set, make sure "id:*" is NOT SET in
read passwd field else SET "id:*" in read passwd field
*/
function CheckPassword($pagename, &$page, &$new) {
global $InputTags;
// get current read password(s)
$rpw = $page['passwdread'];
// Add input field (checkbox) via SDVA ("Set Default Value Array)
SDVA($InputTags["e_public"], array(
':html' => "<input type='checkbox' \$InputFormArgs />", 'name' =>
'public',
'value' => 'yes'));
// If password does NOT contain "id:*"
if (!strstr($rpw, 'id:*'))
SDV($InputTags['e_public']['checked'], 'checked');
}
/* /////////////////////////////////////////
AllowPublicPage()
- should be invoked before the page is stored to set the passwd
- get current page read password(s)
- if checkbox "public" is set, REMOVE "id:*" if present
else SET "id:*" in read passwd field
*/
function AllowPublicPage($pagename, &$page, &$new) {
// $EnablePost is used to check if the page is being stored (???)
global $EnablePost;
// Get current read password(s)
$rpw = $page['passwdread'];
if ($EnablePost) {
// if checkbox is checked ("public=YES")
if (@$_REQUEST['public']) {
// if password contains "id:*"
if (strstr($rpw, 'id:*'))
// remove "id:*" from read passwd
$rpw = str_replace('id:*', '', $rpw);
// else if checkbox is NOT checked ("public=NO")
} else {
// if password does NOT contain "id:*"
if (!strstr($rpw, 'id:*'))
// Append " id:*" (Note the BLANK!) at the end of the read
password field
$rpw .= ' id:*';
}
// Store the page read password
$new['passwdread'] = $rpw;
return;
}

Lars,
Somewhat related, Hans helped me create a recipe that would add an
edit password basically of
id:$AuthUser when creating a profile page.
http://www.pmwiki.org/wiki/Cookbook/FoxPageManagement
The key is a small php program that adds the password before saving.

PHP isn't really so hard if you have enough examples close to what
you want to do.

Peter, thanks for your quick anwer!
I see the $EditFunctions array is a good place to hook in. I assume
you are suggesting to write an own recipe for this, right? I am aware
of the $page['passwdread'] variable and I have checked the file you
suggested, but I am definitely not able to strip out the code
pieces I
need from that file or to code an own recipe.
I have had a look at the cookbook recipe called "EditTitle" before
( http://pmwiki.org/wiki/Cookbook/EditTitle
) to take that as a basis but I figured out that I am not capable of
doing this...
This would be my first recipe, but I need way more code ... or
someone
to do it for me .-)

You can look at the code in WikiSh.php for wshChmod() to see how to
set a password and potentially append to it. Basically it's a
question of reading & setting a value in $page['passwdread'].
Probably you could hook into the $EditFunctions with another
function
that will do what you want it to do.
Hope that gets you started in the right direction.

Can anyone point us into a direction how to do this via a cookbook
recipe or even better - provide the code? We're familiar with PHP
in
general, but we'd like to keep PmWiki as close to the original
distribution for future updates and therefore need support in
"hooking" this into the software.
Tricky sidenote: To be even more precise, if a read password has
already been set by "?action=attr" (i.e. "secret"), we'd like the
recipe to append the "id:*" rather than over-writing the entire
attribute. Same applies for clearing the field. The "id:*" should
be
removed, but everything else should remain untouched.
Thanks a lot in advance.
