[pmwiki-users] pmwiki mirrors

[Petko Yotov]

Yes, it is possible, I use this on a number of websites -- either a home 
server like your case, or a "backup snapshot" of a website from the 
previous night.

To do it, you can have in config.php a conditional based on the server 
name or the server address.

It will help if you have the same server software (e.g. Apache) and PHP 
version on both installations, or have slightly newer versions at home.

You don't need to use relative links, you need to define different 
values to the $EnableReadOnly, $ScriptUrl, $FarmPubDirUrl, $PubDirUrl, 
and $UploadUrlFmt variables.


   if($_SERVER['SERVER_ADDR'] == '127.0.0.1') { # home server
     # or possibly $_SERVER['SERVER_NAME'] == "localhost"
     $ScriptUrl = "http://127.0.0.1/~user/www/pmwiki.php";
     $FarmPubDirUrl = $PubDirUrl = "http://127.0.0.1/~user/www/pub";
     $UploadUrlFmt = "http://127.0.0.1/~user/www/uploads";

     # this is to remind me I am on the home server
     $HTMLStylesFmt['Local'] = '#wikitext {background-color: #ffe 
!important;}';
     $WikiTitle = 'Local wiki';
   }
   else { # online server
     $EnableReadOnly = 1;

     $ScriptUrl = "https://www.your-website.org/wiki/";
     $FarmPubDirUrl = $PubDirUrl = 
""https://www.your-website.org/wiki/pub";
     $UploadUrlFmt = ""https://www.your-website.org/wiki/uploads";

     $WikiTitle = 'Online wiki';
   }

I believe there are some aggressive caching recipes that you may have to 
disable, or to skip the *,cache files from the home server when you 
rsync.

The next step may be to have a static export and rsync that to the 
online server (although, no search, authentication, PmWiki conditionals, 
{(ftime)} markup expressions or other interactive server-side features). 
Static export is not an easy task though.
