Mod_rewrite with Wikka in subdirectory doesn't work
See also: ModRewrite
Symptoms
The installation path of Wikka (relative to the document root) is different from the path used to acess Wikka in the URL. Some examples might be:Installation directory /www/wiki acessed via http://www.example.com/wiki/
Installation directory /wiki acessed via http://wiki.example.com/
Cause
If the path to the subdirectory is the same as the document root plus the subdirectory, the translation should work fine. However, if some kind of aliasing is taking place (as may be the case with hosted sites, though that is not the only possibility) then Apache won't be able to construct the correct URL without a little help.Applies to
All Wikka versionsNote
Future versions of Wikka (> 1.1.6.0) may handle the workaround outlined below automatically.Solution
Use the RewriteBase directive to tell Apache what the URL is for the directory Wikka is installled in. If, for example, Wikka is installed in the directory /www/wiki but it is acessed using http://www.example.com/wiki, you need to modify the .htacess file in the /www/wiki directory (starting with line 7):- <IfModule mod_rewrite.c>
- RewriteEngine on
- RewriteCond %{REQUEST_FILENAME} -d
- RewriteRule ^(.*/[^\./]*[^/])$ $1/
- RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L]
- </IfModule>
- <IfModule mod_rewrite.c>
- RewriteEngine on
- RewriteBase /wiki
- RewriteCond %{REQUEST_FILENAME} -d
- RewriteRule ^(.*/[^\./]*[^/])$ $1/
- RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L]
- </IfModule>
If you would rather add it to your Apache configuration file (httpd.conf), instead of .htaccess, you need to enclose it in a <Directory> and not use the RewriteBase directive:
<Directory /usr/local/www/data/wiki>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*/[^\./]*[^/])$ $1/
RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L]
</Directory>
where the path /usr/local/www/data/wiki corresponds to the absolute server path where your Wikka is installed (change to match your configuration).RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*/[^\./]*[^/])$ $1/
RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L]
</Directory>
CategoryWorkaround
All is working perfectly except that when I try to create a new page by forcing the url to http://wikka.jsnx.com/NewPage the system proposes me to create newpage instead of NewPage. Same problem using the action {{newpage}} or when trying to create NewPage from an existing wikka page.
I have really no idea where it could come from. Any suggestion welcome.
I think you mentioned this problem before (can't search comments), but we didn't figure it out. What OS is your Wikka running on? I'm wondering if it could be Windows doing this, or some setting in your httpd.conf.
I have a windows 2k/apache/mysql base. The problem could come from my httpd.conf althrough I cannot identify anything wrong.
Sorry, I just could not remember *where* we discussed it. Just did some more digging and probably found a clue; see the added a comment to the discussion on the ModRewrite page. Hope that helps!
I hope this saves someone from banging their head like I have been for the last couple of hours.
