Hi All,
I'm developing a wiki-esque application for an in-house project and am wondering how others go about resolving potential conflicts when multiple users are editing the same content drawn from a MySQL database? In particular, I'm working on code that allows users to rename 'pages' (ie the value in the 'pagetitle' field for the record currently being displayed). Theoretically, there may be other records in the table that have intra-record links to the record being renamed (I'm using the Markdown syntax [see http://daringfireball.net/projects/markdown/syntax and http://www.michelf.com/projects/php-markdown/] in the content fields). In a perfect world, I should just be able to run a MySQL replace function across any records that contain the old page title, replacing the value with the new page title, however I foresee a problem if a user is currently editing content from a record that has the old page title. When that user saves their changes, it will currently overwrite any changes made by the MySQL replace function. So, I'm wondering, how do others handle potential conflicts of this kind? This conflict should be just as relevant to the idea of two users concurrently attempting to edit the same record, as it does to the specific situation outlined above. Any help appreciated! Much warmth, Murray
