New Bug in RC2?

[sojomy]

I just did a clean install of osC 2.2 RC2 and I am getting a new error that I did not get in RC1 or any version before that I've used. I can't make it happen myself, but I am getting these errors sometimes. When it happens it will show up 3-5 times in the log file and it's at random times. The IP address I got from the access log at that time was 66.249.70.77 which comes back as a googlebot. Here is the error

 

[21-Jan-2008 15:12:19] PHP Warning:  array_key_exists() [<a href='function.array-key-exists'>function.array-key-exists</a>]: The second argument should be either an array or an object in C:\Webroot\DOMAINNAME\includes\functions\sessions.php on line 127

 

In my sessions.php file, the RC1 version is

return isset($_SESSION[$variable]);

And the newer RC2 version is

return array_key_exists($variable, $_SESSION);

 

 

It seems that the error is because the array_key_exists function is called using the $_SESSION variable, and the $_SESSION variable isn't set at the time this code is run. I'm assuming that the errors I am getting are because google (or other) spiders are crawling through the site and they don't create a session variable, but I'm confused as to why. And more importantly, why was the code changed, and should it be changed back or changed to something else to not give errors when a spider visits the site?

RC2 - release candidate, it doesn't mean the final stable release. you will get few more bugs in RC2.

Try this to fix it.

return (is_array($_SESSION) ? array_key_exists($variable, $_SESSION) : false);

 

I guess this would be a reason to change it.

 

Example#2 array_key_exists() vs isset()

isset() does not return TRUE for array keys that correspond to a NULL value, while array_key_exists() does. 

<?php
$search_array = array('first' => null, 'second' => 4);

// returns false
isset($search_array['first']);

// returns true
array_key_exists('first', $search_array);
?>

Try this to fix it.

return (is_array($_SESSION) ? array_key_exists($variable, $_SESSION) : false);

I'm using RC2. I tested this several times in my local machine.

If "Force Cookie" is enabled/true and the customer doesn't have the site cookie present,

this message shows up in several lines.

Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in catalog\includes\functions\sessions.php on line 127

 

The warning message disappears when 1. the user clicks any link a few times within the site thus setting a cookie OR

2. "Force Cookie" is disabled/false in sessions.

 

This is my line 127 with your fix applied(blue). I Commented the offending line (red).

 

function tep_session_is_registered($variable) {

if (PHP_VERSION < 4.3) {

return session_is_registered($variable);

} else {

//return array_key_exists($variable, $_SESSION);

return (is_array($_SESSION) ? array_key_exists($variable, $_SESSION) : false);

 

Thanks for this fix. It works.

This didn't fix for me.

 

I got this error after installing AJAX Attribute Manager contribution.

 

Here's the error msg I'm getting...

The error msg only comes up in the Product add/edit page right above the attributes template.

 

Please help. Thanks

This didn't fix for me.

I have solved it.

 

bellow:

About the 123 error !

In:

admin/includes/functions/sessions.php

change

line 123 "return isset($_SESSION) && array_key_exists($variable, $_SESSION);"

to

return isset($_SESSION[$variable]);

[arietis]

return isset($_SESSION[$variable]);

 

i'm not sure you want to use this, for the reason stated in the third post in this thread by user99999999: isset() does not return TRUE for array keys that correspond to a NULL value, while array_key_exists() does. this is likely the reason for the code to be changed to what you have now.

 

the following code, posted previously, should work:

return (is_array($_SESSION) ? array_key_exists($variable, $_SESSION) : false);

 

if that doesn't, try using the following:

return isset($_SESSION) && array_key_exists($variable, $_SESSION);

 

this is what my code looks like, which is from a recent code release and i haven't had any problem with it.

 

there really isn't much difference between the two, so i'm not sure why you'd be having problems with the first example. if you're still having problems, post the code you're using. there might be some other subtle difference causing the problem. it could also have something to do with the version of php you're using - so let us know which version.

[Paul J. McCain]

thank you so much, I was having the same problem! I had the attributes manager and then upgraded to RC2. The second suggested fix worked!

 

return isset($_SESSION[$variable]);

 

Thanks!

Paul

[Alex Zuyev]

I had the same error and return isset($_SESSION[$variable]); helped! Thanx!

[morehawes]

Same problem, this also worked for me:

 

return isset($_SESSION[$variable]);

[♥FWR Media]

Same problem, this also worked for me:

 

return isset($_SESSION[$variable]);

 

Joe.

 

This is not correct it should be ..

 

return ( isset($_SESSION) && is_array($_SESSION) ? array_key_exists($variable, $_SESSION) : false );

[♥FWR Media]

Actually no RC2a code is correct ...

 

return isset($_SESSION) && array_key_exists($variable, $_SESSION);

 

What's happening is some bad code is creating a scalar variable called $_SESSION when the session is not set.

 

Therefore $_SESSION exists but it is not an array.

 

By breaking the code as listed in posts above you are just hiding the error with bad code.

[morehawes]

OK, thanks for the info!

[bhbilbao]

Need urgent help with this problem.

 

I have tried diferent methods:

 

1

return isset($_SESSION[$variable]);

2

return ( isset($_SESSION) && is_array($_SESSION) ? array_key_exists($variable, $_SESSION) : false );

3

return isset($_SESSION) && array_key_exists($variable, $_SESSION);

4

error_reporting(E_ALL & ~E_WARNING & ~E_NOTICE & ~E_STRICT);

5

error_reporting(0);

6

error_reporting(E_ERROR | E_WARNING | E_PARSE);

 

 

Please help, I dont know what could be the correct code.

 

My problem is with Google Index SEO, when searching the net with google if I click on See Cache versión, it appears the uggly errors reporting, in special this report.

 

Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in /homepages/6/d3086888888/htdocs/includes/functions/sessions.php on line 127

 

P.D: on normal view on the web there is no errors reporting, only when clickin the caché version.

My php versión is 5.2, osCommerce 2.2 Milestone 2 (I dont know if I installed the 2.2rc2a, how to know this?)

[Jan Zonjee]

Please help, I dont know what could be the correct code.

The line 3 (see last post of FWR Media in this thread) is the one that will be in the next version. I suppose it will take a while before these cached versions will be gone from Google.
