doubt in session

[darisiravi]

hello,

problem : the same member should not be able to be logged in more than once at the same time.

i tried this one, but i got some problems.

table is :

user_id varchar(20)
user_password varchar(20)
enabled varchar(3)

for this, i done using database. when the user logged in, then the user set enabled to "yes". but when the user is logged out then the user set enabled to "no".
suppose, if the user is logged in. the user just close the browser with out using the logoff link. in this situation, how the user set enabled to "no".

Have a timestamp in the table showing when the user last moved (ie every time a user goes to a page on the site this timestamp is updated) then you can check this timestamp and set enabled to "no" if the user has not moved for more than a certain amount of time. This is the usual way of doing it for things like "Users currently online". An alternative would be to do it with javascript but I'm not sure how this would be done.
