== Estensione Restrict access by category and group ==

https://www.mediawiki.org/wiki/Extension:Restrict_access_by_category_and_group

Abbiamo modificato questa estensione per:
* permettere agli utenti loggati di vedere le pagine definite private
* Impedire ai visitatori non loggati di vedere suddette pagine

== Installazione ==

Abbiamo creato il file {{code|extensions/RestrictAccessByCategoryAndGroup/RestrictAccessByCategoryAndGroup.php}} con questo contenuto:
<pre>
<?php

if ( !defined( 'MEDIAWIKI' ) ) {
die( 'Not a valid entry point.' );
}

$wgExtensionCredits['parserhook'][] = array(
'name' => 'Restrict access by category and group',
'author' => 'Andrés Orencio Ramirez Perez',
'url' => 'https://www.mediawiki.org/wiki/Extension:Restrict_access_by_category_and_group',
'description' => 'Allows to restrict access to pages by users groups and page categories',
'version' => '2.0.1'
);

$wgHooks['userCan'][] = 'restrictAccessByCategoryAndGroup';

function restrictAccessByCategoryAndGroup( $title, $user, $action, $result ) {

$wgWhitelistRead[] = wfMsgForContent( 'mainpage' );

$systemCategory[ $formatedKey ] = $value;
}

//Is this page a white page?
if ( isset( $wgWhitelistRead[0] ) ) {
$whitePage = in_array( $title, $wgWhitelistRead );
}

//If the page has no categories, it's public.
if ( count( $title->getParentCategories() ) == 0 ) {
$validCategory = true;
} else {
//For each system categories
foreach ( $wgGroupPermissions as $key => $value ) {
//If current system category is defined as private, then tmpCatP is true
if ( isset( $wgGroupPermissions[ $key ]['private'] ) ) {

} else {

}

if ( array_key_exists( strtolower( str_replace( " ", "_", $key ) ), $systemCategory ) ) {
if ( $privateCategoryTemp and !$privateCategory ) {
$privateCategory = true;
$validCategory = false;
}
//We see that the user belongs to one of the groups (like of category)
if ( in_array( $key, $user->getGroups() ) and ( !$privateCategory or ( $privateCategoryTemp and $privateCategory ) ) ) {
$validCategory = true;
}
$groupExists = true;
}
}
$pageHasCategories = count( $title->getParentCategories() ) > 0;
}

if ( !$pageHasCategories ) {
return true;
}
if ( !$groupExists and !$whitePage ) {
return true;
}
if ( ( $user->isLoggedIn() and $validCategory ) or $whitePage ) {
return true;
}
return false;
}
</pre>

Abbiamo importato l'estensione modificando il file {{code|}} aggiungendo le righe
<pre>
// estensione protezione accesso alle pagine private
require_once "$IP/extensions/RestrictAccessByCategoryAndGroup/RestrictAccessByCategoryAndGroup.php";
// blocco delle pagine con categoria "Private"
$wgGroupPermissions['Private']['private'] = true;
</pre>

Ora basta inserire nella pagina la categoria inserendo il codice
<pre>
[[Category:Private]]
</pre>
