Try to insert in your 'locked' field an Unix date instead of 'locked' .

Just put a timestamp field into the table, which will automatically track the last update of that row. Prior to doing a write, lock the table, and then compare the timestamp at retrieval time to the current timestamp. If it's identical, write the data and unlock. Otherwise, display an error and unlock, or do whatever else you want to do to handle the error. -- Work: It's not just a job, it's an indenture. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] locking a mysQL row
Hi all, I'm currrently developing a dynamic, user-added content site. The thing is, content can be added and edited my TWO people.. the original writer, and the editor. So, my problem is, if the editor/user makes an edit to content whilst the other is also attempting to do so, one of them will get overwritten. This isn't the end of the world, but it's a bit of a problem i'd like to clear up. So, my initial thought was to add a new column to the code "locked" with a time that the code can be re edited. 1. when the user requests to edit the content, the program first makes sure any "locked" time has expired. 2. he/she is given a time limit (say 10 minutes) to edit and re-submit, during which time the annother user cannot edit or change the content. 3. when the user submits the edited content, the locked timestamp is deleted, so that the content can be re-edited earlier than the 10 minutes. 4. if the user submits after the 10 minutes, they are rejected, since the content may have been edited by annother user. Does this seem like a good move? Can any one offer any firther tips or a smarter way to do this?
