I keep having the same problem when i run my script on the server. the error is Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/alliapop/public_html/ekloges2010/ekloges2010/eisagogi.php:1) in /home/alliapop/public_html/ekloges2010/ekloges2010/includes/session.php on line 1 I know i have to put session start at he very first line and i did but the problem keeps showing up. What else should i check?

what does the # symbol do in php(e.x index.php?cat=1#privacy)? How can i use it? From what i 've seen you use it for changing a whole div without reloading the page like tabs..

Yes, i know how to use session start and i know how to use just sessions without cookies. My main problem is how am i goiing to restore the session when the user comes back to my web page. Should i store the session name in a cookie and also in a table in my database and check if they match? or should i check if the users ip is the same with that on the cookie?What is the best practice when you want to restore a session after the browser is closed and reopoened?
-
So step by step what i'm going to do: user types in username and password. with the php post method i check if they are correct. If they are i set the user id and username in the session. I also set the users ip inside a cookie. Now when the user closes the browser the session is destroyed. When the user reopens the browser and comes back to the web page i check to see if the user ip is the same as the user that came back. If it is i set once again in the session the usename and user_id. Is that correct? BTW how come php remebers my username even if my ip has changed?
-
right, the user ip, forgot about that. Whats a token?
-
Thanks for the reply, you got me kind of covered. But if i use session, when the browses closes so does the session. How am i supposed to restore the session when the user reopens the browser. If i store the session id inside a cookie whould that be ok(is it true that firefox does that automaticaly unlike iexplorer)? And how am i supposed to prevent another user from stealing the session id.
-
So for example, if i have a web site where user can log in and post stuff like php freaks, if a use session, when the browser closes the session is destroyed. If i use cookie it will remember the user. But wouldn't it be a safety risk?
-
What is the best practice to use cookies and sessions? Should i create a cookie and keep inside the cookie the name of the username the user has logged in or a session? How am i supposed to compine theese two? Is there any example or a tutorial on this? For example how does php freaks sessions and cookies work.

Ok, everything fixed. I forgot to close one div tag. So i guess firefox bybass the problem and fixes it but iexplorer won't do that.
-
I have the following problem. I have some div tags and inside of the some other div tags like this <div> <div id="div1" float:left> (some other div tags) </div> <div id="div2" float:right> (some other div tags) </div> </div> the problem is that in firefox the div2 floats right but in iexplorer goes below the div1 tag. a tested with javascript to find the parent nodes and they had different in iexplorer and different in firefox. does any one know what may cause the problem?

so the only thing you have to do to cancel the form from going to the next post page is to return false to the onsubmit function?
