| Manually setting this variable to the absolute path to MediaWiki on disk from {{ll|Manual:LocalSettings.php|LocalSettings.php}} was necessary in older versions of MediaWiki.
| |
| However, at least since MediaWiki 1.18, manually defining <code>$IP</code> in LocalSettings.php is no longer needed and no longer works as you may expect.
| |
| It will default to the current working directory and it can be used without the need to define it manually.
| |
|
| |
|
| If you have to override the default value you have to declare the environment variable <code>MW_INSTALL_PATH</code>.
| | [[Category:Templates{{#translation:}}]] |
| See the documentation of your webserver for how to do it.

| {{note|1=Note that you can't just override <code>$IP</code> from your {{ll|Manual:LocalSettings.php|LocalSettings.php}} if you do not want to fix also all the variables that are based on it, like {{ll|Manual:$wgExtensionDirectory|$wgExtensionDirectory}} etc.}}

| | |
| == Details ==
| |
| | |
| IP stands for '''I'''nstall '''P'''ath. The variable holds the local file path to the base installation of your wiki. If for whatever reason you want to overwrite its default - make sure you refer to the fully qualified file path. Do not include a slash at the end of the path.
| |
| | |
| In MediaWiki 1.16 and prior, where the {{ll|Manual:DefaultSettings.php|DefaultSettings.php}} file still had to be loaded from inside LocalSettings.php, the directory to load it from was determined by the IP variable.
| |
| | |
| Unlike other variables, the default is set in WebStart.php instead of in DefaultSettings.php.
| |
| | |
| Setting the <code>MW_INSTALL_PATH</code> environmental variable can sometimes be useful when running maintenance scripts that are in non-standard directories. (Maintenance scripts by default use the parent of the current working directory as $IP).
