Plugin Updates: Website Membership, Facebook Login, Twitter Login (Updated Feb 7)

I'm getting the following error on the user-login.php page:

setPrefixedCookie: Can't set cookie, headers already sent! Output started in /home/qaa/public_html_staging/user-login.php line 4.

It probably has somthing to do with the fact that I have a php insert for all the sites standard viewers?

Hi Tim, 

Cookies and session data need to be sent before any content.  

The usual cause of the "headers already sent" error is extra whitespace before, after, or between tags.  Check on line 4 of /user-login.php for anything like that and remove it if possible.

Then check your include files before whitespace before the first <?php, after the last ?> or between tags, like this: 

?>
<?php

Replace with: ?><?php

Let me know if that fixes it.  Thanks!

Hi Dave,

The plugin Twitter causes a problem with the use of the sessions.

> Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time in lib/init.php on line 454 Couldn't start session! 'A session had already been started - ignoring session_start()'!

For the moment, I added session_destroy() in the header of my file (it is a contact form with a captcha) and that seems to function.

    session_start();
    session_unset();
    session_destroy();
    session_write_close();
    setcookie(session_name(),'',0,'/');
    session_regenerate_id(true);

An idea?

Thanks!

That's done it - thanks Dave!

Hi Dave,

I've installed the latest beta CMSB, membership, facebook, twitter...  I've then duplicated the accounts.ini.php, removed the "accessList" section and saved as members.ini.php

I've then updated the websitemembership.php : $GLOBALS['WSM_ACCOUNTS_TABLE']            = 'members';

It goes fine until I add an email address at the twitter-connect.php and I get the error: MySQL Error: Unknown column 'disabled' in 'field list' (at outgoingMailer.php line 47 in function mysql_insert)

Any thoughts?

That fixed it!

Thanks!

Hi Djulia, 

I wanted to get back to you about the Twitter Login session issue.  What I've done for now is add some code so the plugin won't start a session if a session is already active.  I checked session_id() for that like this:

// make sure session is started (for storing twitter data)
if (!session_id() && !defined('START_SESSION')) { define('START_SESSION', true); }

That will work in this case because Twitter Login only stores it's own information in the session, not anything from CMSB.

When you use two php applications that use sessions there is a problem because each application might be setting up sessions differently.  If this comes up more often maybe what I could do is add some functions that would allow you to save and restore CMSB sessions.  So if you need to use another application that also uses PHP sessions they wouldn't conflict.  Or we could always just write out own session handler and emulate what php does.  So we'd use $CMS_SESSION or something different.

It's a bit tricky, but I'll give it some more thought.  Let me know if you run into any more issues with sessions, and thanks for you ongoing feedback and support.

Thanks! :)

Thanks everybody for your feedback, we've released all of these plugins out of beta.  Cheers!
