The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

PHP Session expire/close detection

Asked by micamedia in PHP Scripting Language

Tags: session, php, expire, close

I need a way to detect session close/expire and run a task when this happens. Here's the the situation:

I have a custom shopping cart. When people add x of an item to the cart, the system "locks" x items. Meaning it takes them temporarly from the inventory. After 20 min or inactivity it will unlock the items. Each time the cart loads it will attempt to relock the items reseting the time.

This all works perfectly. My problem is this:

Say someone puts 10 items in the cart. 10 items are locked. Now the user closes the browser. The cart session goes away, but the 10 items are still locked. They will remain locked for 20 min. I would like to just remove the locks when this happens. But i don't know how to detect this.

I need a way to be able to tell when my $_SESSION["order_id"] is closed or expired. And when it does it gets even more complex. In order to remove the locks, i need to know what the order_id was.

So in summary, i need to know when $_SESSION["order_id"] goes away, and what it was so i can then delete the locks associated with the order.

Of course if you have another idea of how to do this, i'm all ears.
