CL Auth [BETA] v0.2.5 - Printable Version

Code:

==========================================================================

function CI_Session()

==========================================================================



--------------------------------------------------------------------------

ADD AFTER "$this->CI =& get_instance();"

--------------------------------------------------------------------------

// CL_Auth config settings

$this->track_activity = $this->CI->config->item('track_activity');

$this->regen = $this->CI->config->item('regen')



==========================================================================

function sess_run()

==========================================================================



--------------------------------------------------------------------------

ADD AFTER introduction comments

--------------------------------------------------------------------------

if (is_numeric($this->CI->config->item('sess_time_to_update')))

{

    $this->time_to_update = $this->CI->config->item('sess_time_to_update');

}





--------------------------------------------------------------------------

CHANGE ELSE STATEMENT AFTER if ( ! $this->sess_read()) { $this->sess_create(); }

--------------------------------------------------------------------------

// Activity Function for CL_Auth

if ( $this->userdata['session_user_id'] != 0 AND $this->CI->config->item('CL_Auth') === TRUE AND 



$this->track_activity === TRUE )

{

    $this->CI->load->model('cl_auth/users', 'users');

    $active = $this->now - $this->userdata['last_activity'];

    $this->CI->users->update_activity($this->userdata['session_user_id'], $active);

    $this->sess_update();

}

// We only update the session every five minutes

elseif (($this->userdata['last_activity'] + $this->time_to_update) < $this->now)

{

    $this->sess_update();

}





==========================================================================

function sess_read()

==========================================================================



--------------------------------------------------------------------------

MANY DIFFERENCES, ONLY THING IMPORTANT TO CL_AUTH WAS THE FOLLOWING I THINK

ADD BEFORE THE CHECK "$query->num_rows() == 0"

--------------------------------------------------------------------------

// This section of code is new

if ( $this->CI->config->item('CL_Auth') === TRUE )

{

    $users_table = $this->CI->config->item('CL_table_prefix').$this->CI->config->item



('CL_users_table');



    $this->CI->db->from($this->session_table);

    $this->CI->db->join($users_table, $users_table.'.id = '.$this-



>session_table.'.session_user_id', 'left');



    $query = $this->CI->db->get();

}

else

{

    // Normal session query

    $query = $this->CI->db->get($this->session_table);

}



==========================================================================

function sess_create()

==========================================================================



--------------------------------------------------------------------------

SOME DIFFERENCE, NOT IMPORTANT TO CL_AUTH I THINK?

--------------------------------------------------------------------------



==========================================================================

function sess_update()

==========================================================================



--------------------------------------------------------------------------

REPLACE THE STATEMENT if ($this->use_database === TRUE) { [...] }

--------------------------------------------------------------------------

// format query array to update database

$ud = $this->userdata;

$sql_ary = array(

'session_id'    => $new_sessid,

'session_user_id' => $ud['session_user_id'],

'last_page' => $this->CI->uri->uri_string(), // Grab current page they are on

'last_activity' => $ud['last_activity']);



unset($ud['session_id'], $ud['session_user_id'], $ud['last_page'], $ud['last_activity'], $ud



['user_agent'], $ud['ip_address']);



$sql_ary['session_data'] = serialize($ud);

$this->CI->db->query($this->CI->db->update_string($this->session_table, $sql_ary, array



('session_id' => $old_sessid)));



==========================================================================

function set_userdata()

==========================================================================



--------------------------------------------------------------------------

ORIGINAL USES sess_write() AT THE END, BUT THE CL_AUTH USES sess_update()?

--------------------------------------------------------------------------



==========================================================================

function unset_userdata()

==========================================================================



--------------------------------------------------------------------------

SAME DIFFERENCE AS set_userdata()

--------------------------------------------------------------------------



==========================================================================

function _flashdata_sweep()

==========================================================================



--------------------------------------------------------------------------

CHANGED TO

--------------------------------------------------------------------------

function _flashdata_sweep()

{

    $i=0;

    $userdata = $this->all_userdata();

    foreach ($userdata as $key => $value)

    {

        if (strpos($key, ':old:'))

        {

            unset($this->userdata[$key]);

            $i++;

        }
