file last updated with cookie?
Anyone know how to do this...I maintain a list of AUTOCAD files which sometimes get changed. I want to highlight the drawings which have changed from the users last visit via css...any pointers appreciated. |

In a nutshell.... - Store a cookie on the users system with the date/time (perhaps Unix epoch time would be best) of their last visit to the page that lists the files. - Everytime a cad file is updated, store the updated time in the database. - Have a script display the files from the database and compare the time on the DB with the time in their cookie - If the time in the DB is greater than the time in their cookie, flag that record/file. That's pretty much how I'd tackle the problem. Of course it means you'd need to have a database running but that shouldn't be too hard ? Or are you are reading in a directory list of files straight off the server ? If that is the case, you can retrieve the time of the last change/update from the file info although that method would be slower and more CPU intensive. - Mike |
