Re: Cache / file.php / unserialize() error
This should be fixed in #769
http://cakephp.lighthouseapp.com/projects/42648/tickets/769
We're working towards packaging another release for this as soon as possible.
Cheers,

Re: unserialize error
hey,
session data are serialized. i failed with php command
"unserialize", because of the "|" signs, which apparently
separate subarrays.
i found no other way of getting the data out of the session.
see this example:
$account_in_use = false;
$temp = mysql_query('SELECT * FROM sessions');
while($row = mysql_fetch_array($temp)){
$vars = array();
$a = preg_split( "/(\w+)\|/", $row['data'], -1, PREG_SPLIT_NO_EMPTY
| PREG_SPLIT_DELIM_CAPTURE );
for($i = 0; $i < count($a); $i = $i+2){
$vars[$a[$i]] = unserialize($a[$i+1]);
}
if(isset($vars['User']['id']) && isset($vars['User']
['logged_in'])){
if($vars['User']['id']==$someone['User']['id'] &&
$vars['User']
['logged_in']==1){
$account_in_use = true;
break;
}
}
}
this piece of code helps checking for the logged_in status.
i'm wondering if you have usernames only in the sessions ?
can you read the usernames from another table, which is
related to the session entry ?
i would have been better of storing the logged_in status in another
table... but anyways, it works for now...

Re: unserialize error
gc works fine now,
How to extract some value from $session['Mysession']['data']
like User.username ?
I would like to find all logged users (by username). () without stuff
like:
$a = preg_split( "/(\w+)\|/", $row['data'], -1,
PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE );
Is there another way?

Re: unserialize error
finally i found a way to implement a custom
session garbage collection. luckily there
is the "expires" field which can be evaluated
instead of the serialized value in the data array:
// custom session garbage collection
$sessions = $this->Mysession->findAll();
foreach($sessions as $session){
if($session['Mysession']['expires']Mysession->del($session['Mysession']['id']);
}
}
use the mysession model i posted above.
majna, wasn't it this what you have been looking for ?
cheers, jyrgen

Re: unserialize error
valid sessions on my system look like this
Config|a:3:{s:4:"rand";i:1735136669;s:4:"time";i:1175943092;s:
9:"userAgent";s:32:"cc98eaffc23c634e0efd75ab9e36e810";}
User|a:5:{s:2:"id";s:1:"6";s:9:"author_id";s:1:"5";s:
12:"publisher_id";s:1:"0";s:9:"logged_in";i:1;s:4:"type";s:1:"A";}
(two arrays)
i'm asking myself if the "|", lets my reading fail...
this works for my, instead of unserialize:
$temp = mysql_query('SELECT * FROM sessions');
while ($row = mysql_fetch_array($temp)){
$variables = array( );
$a = preg_split( "/(\w+)\|/", $row['data'], -1,
PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE );
for( $i = 0; $i < count( $a ); $i = $i+2 ) {
$variables[$a[$i]] = unserialize( $a[$i+1] );
}
}
should be combined with a session model in order to
avoid explicit sql quering.
i can live with that :-)
still searching for a method to collect session garbage.
once i got this done, multiple logins are prevented and
my auth system will be finished...

Re: unserialize error
Also I need to grab username from session. Sessions are set to
database. Cake 1.1.13.
Session data filed is NOT just serilalized. Is there any other way
beside reg exp?

Re: unserialize error
oops. i just noticed that the Session model interferes
with the Session object.
therefore i renamed the Session model into
mysession.php
class Mysession extends AppModel{
var $name = 'Mysession';
var $useTable = 'sessions';
}
j.

unserialize error
i'm still struggling with reading data from the sessions
table.
at least i'm now able to retrieve session entries, after
i set up a simple model like this.
class Session extends AppModel{
var $name = 'Session';
}
but when i try to print out the session data in a controller
$sessions = $this->Session->findAll();
foreach($sessions as $session){
$d=$session['Session']['data'];
pr(unserialize($d));
}
i get this error:
Notice: unserialize(): Error at offset 0 of 117 bytes in /var/www/cake/
app/controllers/users_controller.php on line 88
with 117 being the last position "}" of the serialized string
Config|a:3:{s:4:"rand";i:1024300043;s:4:"time";i:1175942427;s:
9:"userAgent";s:32:"cc98eaffc23c634e0efd75ab9e36e810";}
thanks for your help!
