I keep getting this warning in a phpbb2 script after adding a mod (i must say that this file hasn't been edited)

Warning: mysql_free_result(): supplied argument is not a valid MySQL result resource in /mounted-storage/home43a/sub004/sc31952-BMDX/www/forum/db/mysql4.php on line 319

This is the code in that line of the file:

            if ( $query_id )
            {
                  unset($this->row[$query_id]);
                  unset($this->rowset[$query_id]);

                  mysql_free_result($query_id); //line 319

                  return true;
            }
            else
            {
                  return false;
            }
      }

How can i fix this??

When i print the content of the variable $query_id I get  this "Resource id #351"

try and track down where $query_id is declared, and see if it is a connection link to mysql database.

You can temporarily suppress the error message:
@mysql_free_result($query_id);

but off course, you should fix up the error if possible.

It is in this function:


      function sql_freeresult($query_id = 0)
      {
            if( !$query_id )
            {
                  $query_id = $this->query_result;
            }

            if ( $query_id )
            {
                  unset($this->row[$query_id]);
                  unset($this->rowset[$query_id]);
                  mysql_free_result($query_id);

                  return true;
            }
            else
            {
                  return false;
            }
      }

the @mysql_free_result( suggested by nizsmo only hides the error .
The above solves the problem .
