SESSION Array problem - possibly different PHP versions?

Hi All,

I have a problem that only occurs on our live server and not our local
server.

It works fine locally.

Basically I am using a session array to store values of product colours. A
user can add colours to the session array.

The session is defined as follows:

$_SESSION['color'][$counter] = $color;

Obviously the first time we validate and the $counter is set to 0.

When more colours are added the $counter variable increments and should
increment the value of the array.

The colours are added through a popup window. Before I open the popup window
I print_r($_SESSION['color']) to view the contents of the array and make
sure that they are valid and it is an array.

Output is as follows:

[color] => Array ( [0] => #339933 [1] => #cccc00 ) etc...



Then once the popup opens I do the same print_r

And it now shows: [color] => #339933

There fore it isn't an array of colors within the session array. How can PHP
change this? Also the strange thing is that locally it works fine but not
live. So I am guessing that there is a problem with a certain version of
PHP?

Also Im not sure what else could be causing this problem?

Any ideas or hints would be appreciated.

Thanks




Kind regards,

From where is the color data coming in to the script, a database?
Check to make sure that the array is being populated. Also, you're
not attempting to pass the session from your dev box to your live box,
are you?

Hi Daniel, thanks for the reply.

The system works as follows.

There is a colour picker, when a user clicks on a colour then it opens a
popup window with the color set as a GET variable.

They can then enter the price per colour etc... once done, they save it. It
then saves the details to a session.

The user then closes the window and it refreshes the parent page which has
the colour picker and a listing of selected colours already choosen, after
the refresh it shows the array values (print_r) and is correct the first
time:

[color] => Array ( [0] => #339933

Then if they do the same procedure again, once the popup opens it shows the
session variable as:

[color] => #339933

But nothing has been done to the SESSION variables since the save, so
somehow between the the click and the popup opening something strange is
happening.

Like I mentioned it works on a local laptop as well as our local server so
its strange, I have tried many times closing the browser to ensure all
sessions are cleared.

Any ideas what might be causing this error?

Thanks very much

Put a print_r($_SESSION) at the top and bottom of your page code so you can see
what's happening.

Also check your code that updates the session assignment by the GET value. It
appears your code maybe unset()ing the session assignments.

Are you using Cookies? If so, check this code carefully as it can cause non
obvious things depending on whether the client machine has cookies enabled or
disabled.

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

Thanks will do so going to check the unset() as well as the print_r at top
and bottom, also I am not using cookies hope to get this sucker working.

Will keep you posted.
