| - | The trick is to find how Piwigo can understand if it's currently running gallery1 or gallery2. In this example, we have used the $_SERVER['SCRIPT_NAME'] variable. You can also use an environment variable set by your webserver or the servers name in the $_SERVER['SERVER_NAME'] variable (if you search for a specific sub-domain). If no Alias or Server Name matches it will just use the default, root gallery. | + | The trick is to find how Piwigo can understand if it's currently running gallery1 or gallery2.

| + | |||
| + | [[user_documentation:albums_management|Physical Albums]] (aka Synchronization) for Multisites are not yet (means version 2.5.1) supported out of the box. I mean all that stuff in the //galleries// directory. The main issue here is, that all sites of a Multisite installation are sharing this directory. An other issue is that with the current code directory traversals are possible to just import an others gallery. | ||
| + | |||
| + | Either you disable Synchronization with the following code snippet in your local/config/config.inc.php: | ||
| + | <code php>// disable the synchronization method for adding photos | ||
| + | $conf['enable_synchronization'] = false;</code> | ||
| + | |||
| + | Or you just hack the code as described in [[http://piwigo.org/forum/viewtopic.php?id=22173|[Forum, topic 22173] physical albums are not multisite save]]. | ||
| + | |||
| + | Let's some it up here. | ||
| + | |||
| + | ==== Pimp Synchronization for Multisites ==== | ||
| + | |||
| + | Due to the path for the //galleries// directory is nowhere configured as for upload_dir and data_location we need to put site_dir into the $conf variable. Just add the following to the ''if (isset($site_dir))'' statements from above. | ||
| + | |||
| + | <code php> $conf['site_dir'] = $site_dir;</code> | ||
| + | |||
| + | Also we need to adapt admin/site_manager.php to prefix the //galleries// directory with the site_dir at creation time. Already existing //galleries// directories will not be prefixed automatically, you have to change them on your own in the database in table piwigo_sites. | ||
