Extension:ImportUsers

The ImportUsers extension adds special page, "Special:ImportUsers", which can be used by bureaucrats (or other users who have the  permission) to import users from a CSV file to MediaWiki's user database.

Import File Format
The CSV file in UTF-8 without BOM encoding consists of four or five columns, delimited with commas: Be sure the CSV file has the correct line feeds. Files with Macintosh line feeds will process only the first line. user1,pass1,user1@example.org,John Doe user2,pass2,user2@example.org,Jane Doe,editor user3,pass3,user3@example.org,Jonnie Doe,editor,staff
 * 1) username
 * 2) password
 * 3) email
 * 4) real name
 * 5) user groups (optional; if the user is a member of more than one group, put each group in its own column in the CSV file - do not embed them with commas in one column)
 * Example:

Duplicate/Collision handling
This extension will never create duplicate user accounts. Collision handling behavior is determined by the "Replace existing users" check box.

Two accounts are in collision (or are duplicates of each other) if their login names (user names) are equal.
 * What is account collision?


 * What can be done?
 * When "Replace existing users" check box is clear (unchecked), ImportUsers extension will ignore records in the input file which are duplicates of existing accounts.
 * When "Replace existing users" check box is checked, ImportUsers extension will update corresponding accounts with data from input file.

MediaWiki tolerates duplicate email addresses. In other words, there may be multiple accounts connected to the same email address. This extension will not validate for duplicate email addresses.

Configuration

 * User right

The user right " " is by default assigned to the "bureaucrat" user group. In case you would like to assign the right to an additional user group, e.g. "sysop" add the following line to your "LocalSettings.php" file after the inclusion of the extension as described in the "Installation" section above:

Maintenance
After importing users you might want to run initSiteStats.php (MW ≥ 1.21.x) or initStats.php (MW ≤ 1.20.x) to update the statistics of your wiki on registered users.
