Posting Data / needs major editPage.php rewrite
 Need Help At present, user interface code is tightly woven with the database access code, making it unusable for the API. These two must be separated from one another – we need a clean data access layer without any UI logic. If you want to contribute with rewriting EditPage.php, and if you know PHP and MediaWiki, or you think you can learn it, please give us a hand at making this possible. --Yurik 15:07, 17 October 2006 (UTC)

action=submit allows data to be posted back to the MediaWiki servers. For this to work, the client must first obtain an edittoken by using prop=info & intoken=edit query call. Both the lastrev and the token have to be sent to the server, together with the title of the page, its content, and the summary comment. disablemerge parameter stops the save operation in case the article has been modified after the query call. testrun parameter attempts the save operation by merging the content with the newer changes (if needed), and returning how the page would look like if it was saved, but without actually changing any data.

Note: The parameters should be modified to allow for the controlled merge. For example: rev #1 is received, an attempt is made to save changes to it, but rev #2 has been created in the meantime. The client decides to allow merge with rev #2, but while the decision is made, the rev #3 has been published. The client should have the option to only allow merging with rev #2 which was verified, not with rev#3 that it has not yet seen.
