Change database value without page-load?

Hi,

I got a page which contain a lot of rows from a table.
The db-table got a "locked" column (ENUM "0","1").

I display a lock/unlock image to the user, based on the value of this column.
Is it possible to change db value and replace image without a page-load?

The "without a page load" part seems to imply that you would make an AJAX request.  The short answer is "yes, you can do that."  There is an article here that gives the design pattern of a PHP / jQuery AJAX implementation.   It shows how to get around the "page load" issues and still accomplish back-and-forth communication with the server via the standard request/response.

Got a version of this working on my site.  See it here: http://girlzunderground.com/ee.html

Do you need the code explained to you?

You'll need to change all the image names in the javascript code and you'll also need to change what page the ajax call is made to.

Just change the actual image name, you shouldn't have to worry about the path as long as the two images (lock.png / unlock.png) are in the same folder.

Also, you see the function accepts the parameter "id"; this is posted to the page as well--you might want to put the id of the record in the onclick event in the image tag (right now its 1, 2, or 3) and this value will get sent to your page as well.  THought you might want that.
