Using phpBB authentication on other pages

[tempyyyst]

Hi all

I want to use phpBB's authentication to restrict access to a 'user reviews' section on my DVDRecorderWorld site (see sig).

I'm following this tutorial.

Which basically involves sticking code a bit like this into the page:

  define('IN_PHPBB', true);
    $phpbb_root_path = './forum/';
    include($phpbb_root_path . 'extension.inc');
    include($phpbb_root_path . 'common.'.$phpEx);
    
    //
    // Start session management
    //
    $userdata = session_pagestart($user_ip, PAGE_INDEX);
    init_userprefs($userdata);
    //
    // End session management
    //
    
    // phpBB session test
    
    if( $userdata['session_logged_in'] )
       {
          echo('logged in');
       }
    else
           {
                   echo('Please Login');
           } 

but if you take a look at

http://www.dvdrecorderworld.com/reviewtest.php?model=60

you'll see an error message (which annoyingly I can't reproduce once I logged in) involving headers.

Anyone got any tips as you what this means and where I should be looking to fix it?

that error means you've done something that outputs data before using the header function (for redirecting or what not). You cant have outputted data on the same page as a header redirect.

Thanks. So, the headers are first being sent by my parent php page and then something in phpBB is trying to resend.

Any phpBB experts out there come across this before?

Ah, solved the headers problem by moving the phpBB include stuff right to the top of the page, but now I'm getting other SQL errors.

Looks as though having the phpBB session stuff at the top of the page is stopping the passing of the variable $model.

Anyone know why?

<?php
   
   define('IN_PHPBB', true);
   $phpbb_root_path = './forum/';
   include($phpbb_root_path . 'extension.inc');
   include($phpbb_root_path . 'common.'.$phpEx);
   
   //
   // Start session management
   //
   $userdata = session_pagestart($user_ip, PAGE_INDEX);
   init_userprefs($userdata);
   //
   // End session management
   //
   
   include("<include path>/db_connect.php");
   
   echo ("<p>Modelid: $model</p>");
   
 $modelsql = "SELECT model, manu, amazon_asinuk, amazon_asinus FROM model LEFT JOIN manu ON manu_id=manu.id WHERE model.id=$model";
   
   $modelfields = @mysql_query("$modelsql");
   if (!$modelfields) {
       echo("<p>ERROR2:" . mysql_error() ."\n SQL: $modelsql</p>" );
       exit ();
   }

gives me

 Modelid: 

 ERROR2:You have an error in your SQL syntax near '' at line 1  SQL: SELECT model, manu, amazon_asinuk, amazon_asinus FROM model LEFT JOIN manu ON manu_id=manu.id WHERE model.id=

[Gibb]

where were you getting the $model variable from? was it stored in a $_SESSION, or from $_GET?

If you have some code for retrieving $model down below, you'll need to move that up as well.

[loadx]

could be in a different include ?

[tempyyyst]

$_GET

ie.

http://www.dvdrecorderworld.com/reviewtest.php?model=60

Page works fine at:

http://www.dvdrecorderworld.com/review.php?model=60

before I added the phpBB includes.

[Gibb]

then move the code that grabs the $_GET variable to the top of the page, before the phpBB code (so long as there's no echo statements or such that would cause a header error again).

Thanks, that's done it.
