The EditWarning extension displays a warning if user edits a page/section which is currently being edited.
On pages which are being edited by many users simultaneously, edit conflicts can easily happen. This extension tries to avoid this problem by showing a warning message if the user edits a page that is being edited by other users at the same time. It's very similar to the MoinMoin Wiki warning with the difference that it doesn't lock the page.
Note: It's not recommended to use this extension if anonymous users are allowed to edit pages, because it ignores anonymous page edits.
- Download and place the file(s) in a directory called
- Add the following code at the bottom of your LocalSettings.php:
- Execute the following SQL statements in your database:
CREATE TABLE IF NOT EXISTS editwarning_locks ( user_id int(10) unsigned NOT NULL, user_name varchar(255) NOT NULL, article_id int(10) unsigned NOT NULL, timestamp int(11) unsigned NOT NULL, section int(2) unsigned NOT NULL, KEY user_id (user_id), KEY article_id (article_id) ) ENGINE=InnoDB; ALTER TABLE editwarning_locks ADD CONSTRAINT editwarning_locks_ibfk_1 FOREIGN KEY (user_id) REFERENCES user (user_id) ON DELETE CASCADE ON UPDATE CASCADE, ADD CONSTRAINT editwarning_locks_ibfk_2 FOREIGN KEY (article_id) REFERENCES page (page_id) ON DELETE CASCADE ON UPDATE CASCADE;
- The default timeout is set to 10 minutes. If you want to change this setting, add this line to your LocalSettings.php (Note: The value is the number of minutes):
$EditWarning_Timeout = 5;
- The extension hides everything except the editor area (see screenshots). If you don't like this behavior, add this line to your LocalSettings.php:
$EditWarning_OnlyEditor = "false";
Upgrade from 0.3Edit
See the UPGRADE file.
- The extension can only recognize the cancel of page editing if the user uses the "Cancel" button. Otherwise the warning will be showed until the timeout (default 10 minutes).
- When a user tries to edit a page that is already edited by another user and she/he sees a blank page or a page with "Fatal error:Call to undefined function:bcdiv()" you have to install the php module "bcmath".
