POPHP session doesn't work correctly maybe because of fb? please help
text
Body
copied!<p>I have a question about PHP sessions. I use a session to keep a visitor logged in. I have made a site before with this and works perfect. Now I am making a Facebook app.</p> <p>When logging in (checking if user is registered in database), I register <code>id</code>. After that I use:</p> <pre><code>if(session_is_registered("id")) { echo "Logged in"; } </code></pre> <p>So if it shows "Logged in" in the browser, I am absolutely sure that the session is registered. But when I go to the next page (which has session_start(); at the top of the page), there's no session anymore. But if I go to the logout page (with session_destroy();), and then proceed to the login, the session is registered correctly. Also if I close all the browser windows and then go to login, it won't register correctly.</p> <p>I tried destroying the session right before registering the 'id', but that also doesn't work.</p> <p>I'm guessing I made a basic error, so someone on here should be able to help me without wasting a lot of time.</p> <p>Please help me. I have wasted days on this. Thanks in advance.</p> <hr> <p>More code:</p> <p>Where session is registered:</p> <pre><code>$id_query = mysql_query (" SELECT * FROM Tour11_deelnemers WHERE fb_id = '$user'"); while ($record = mysql_fetch_assoc ($id_query)) { $id = $record['deelnemer_id']; } if($id > 0) { $speelid = $id; session_register("speelid"); } </code></pre> <p>After that to check if it is registered:</p> <pre><code>if(session_is_registered("speelid")) { echo "Ingelogd"; } </code></pre> <p>session_is_registered() is same as isset() for $_SESSION.</p> <p>So the thing I don't understand is while session_is_registered() is true after it is registered, on the next page it is false again :( unless I login immediately after going to logging out page (session_destroy();). So even if i destroy the session just before restarting it and registering again, it doesn't help.</p>
