Hi

I get these errors:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /var/www/board.php:1) in /var/www/sessions.php on line 116

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /var/www/board.php:1) in /var/www/sessions.php on line 116

Fatal error: Call to a member function on a non-object in /var/www/sessions.php on line 57

Warning: Unknown(): A session is active. You cannot change the session module's ini settings at this time. in Unknown on line 0

Heres my code

PHP Code:

 $session_life = get_cfg_var("session.gc_maxlifetime");



  //function to open our session

  function session_open( $save_path, $session_name )

   {

      return true;

   }



   //function to close our session

   function session_close()

    {

       return true;

    }



    //function to read the value of a session variable

    function session_read( $sessid )

     {

        global $DBI;



        $query_string = "SELECT data FROM diet_sessions WHERE sessionID = '$sessid' AND expires > ".time();



        //run the query

        $query = $DBI->query( $query_string ); //LINE 57



        $result = $query->fetchRows();



        if( $result )

         {

           return $result->data;

         }



         return false;

     }



     //function to write session variables to the DB table

     function session_write( $sessid, $value )

      {

         global $session_life, $DBI;



         $expire_time = time()+$session_life;



         $values = addslashes( $value );

 //check that this session doesnt already exist

         $check_query_string = "SELECT * FROM diet_sessions WHERE sessionID = '



         $check_result = $DBI->query( $check_query_string );



         $check_num = $check_result->numRows();



         if( $check_num >= '1' )

          {

            $update_string = "UPDATE diet_sessions SET expires = '$expire_time'

                             "WHERE sessionID = '$sessid' AND expires > ".time(



            $update_query = $DBI->query( $update_string );



          }

          elseif( $check_num <= '0' )

          {

 $insert_string = "INSERT INTO diet_sessions VALUES ('$sessid', '$ex



            $insert_query = $DBI->query( $insert_string );



          }



          return $insert_query;

      }



      //function to destroy our session

      function session_end( $sessid )

       {

          global $DBI;



          $query_string = "DELETE FROM diet_sessions WHERE sessionID = '$sessid



          $query = $DBI->query( $query_string );



          return $query;



       }

  function session_gc( $maxlifetime )

        {

           global $DBI;



           $query_string = "DELETE FROM diet_sessions WHERE expires < ".time();



           $query = $DBI->query( $query_string );



           return 1;



        }



        //setup PHP's session handler to use our functions instead of the defau

        session_set_save_handler( "session_open",

                                  "session_close",

                                  "session_read",

                                  "session_write",

                                  "session_end",

                                  "session_gc");



        //finally, startup our session

        session_start();



?> 

my $DBI is a class which is in called in the include.php file.

The $DBI class works, iam certain, but i dont know why the sessions file gives out, and why cant I send out the session_start();
I know its supposed to be at the stop of every script, but in this case as iam writing my owne session functions, it shouldnt matter??

Try to change this:

PHP Code:

            $update_string = "UPDATE diet_sessions SET expires = '$expire_time' 

                             "WHERE sessionID = '$sessid' AND expires > ".time( 

to this (remove that quotemark before WHERE):

PHP Code:

            $update_string = "UPDATE diet_sessions SET expires = '$expire_time' 

                              WHERE sessionID = '$sessid' AND expires > ".time( 

Any help?

edit: nevermind, your whole code seems to be cut from the right...

no difference

You've got some string termination issues on your query strings. You're including code in your query strings because they are not terminated properly with closing quotes.

[perleo]

but if at the top of the script I do

PHP Code:

$query = $DBI->query( "SELECT * FROM table" ); 

it returns the same type of error,


Fatal error: Call to a member function on a non-object in /var/www/sessions.php on line 35

is it the way I call the database script that has the DBI class ?

I do $DBI = new DBI( "mysql://root***@localhost/db" );

at the end of the database script. and then include that in the sessions.php

It's very likely that this is the root of your problem. Not knowing what parameters your class constructor is expecting makes it impossible for me to say for sure. I will say it looks very strange tho.
