[RESOLVED] Session losing 1 value!?

leatherback

Hi All,

On a website I use sessions to store a users'prefernce with regards to color specifications. I have two main setups, one green-based and one brown-based.

Upon loading the page, I check for a swap, which works. The menu gets the right link and all for the color swap. And on my local server the new settings are retained. But on the live server, it doesn't! It will load the new color, but will not retain it to the next page.

When I chect the session array, it resets the value:

First page with new color:

Array
(
    [name] => jelle4
    [colorscheme] => b
)

The second load:

Array
(
    [name] => jelle4
    [colorscheme] => 
)

What am I missing?
Local machine: PHP Version 4.2.3, reg.glob off
Live machine: PHP Version 4.3.10, reg.glob off

The check / set routine:

$colorscheme = getvar('c', '', 2);

if($_GET[c] == "")
  {
  $colorscheme = $_SESSION[colorscheme];
  }
else
  {
  $_SESSION[colorscheme] = $colorscheme;
  }

switch($colorscheme)
  {
  default:   

  $barurl = $baseurl."layout/gif/groen/";
  $stylesheet = $baseurl."layout/colors_m_g.css";
  $menuswap="<a class=\"menu0\" href=\"$_SERVER[PHP_SELF]?c=b\">Swap colors</a>";
  break;

  case 'g':
  $barurl = $baseurl."layout/gif/groen/";
  $stylesheet = $baseurl."layout/colors_m_g.css";
  $menuswap="<a class=\"menu0\" href=\"$_SERVER[PHP_SELF]?c=b\">Swap colors</a>";
  break; 

  case 'b':
  $barurl = $baseurl."layout/gif/bruin/";
  $stylesheet = $baseurl."layout/colors_m_b.css";
  $menuswap="<a class=\"menu0\" href=\"$_SERVER[PHP_SELF]?c=g\">Swap colors</a>";
  break;
}
?>

In you default setting where it says

$menuswap="<a class=\"menu0\" href=\"$_SERVER[PHP_SELF]?c=b\">Swap colors</a>";

Should it not be:

$menuswap="<a class=\"menu0\" href=\"$_SERVER[PHP_SELF]?c=$colorscheme\">Swap colors</a>";

If this is wrong... dont laugh :-P

Hi Biuostall,

Nope.

For some reason at the server there is some overwrite of the session variables whenever they are used as normal variables, which doesn't occur on my server.

By chnging it to:

$colors = getvar('c', '', 2);

if(! isset($_GET[c]))
  {
  $colors = $_SESSION[colorscheme];
  }
else
  {
  $_SESSION[colorscheme] = $colors;
  }

switch($colors)
  {

it was solved.

Still strange, guess I'll have to read up on sessions again..

Just one more thing. I've only been working with sessions for a short amount of time but when you do $SESSION[colorscheme]... should it not be $SESSION['colorscheme']?? Maybe its just me being dumb (again) lol

Sorry, but yes, it's you being a typical person. Nobody can know everything about a language, so it's understandable that everyone will come up with errors every now and then.

$SESSION[colorscheme] is syntactically correct, however, standards prefer $SESSION['colorscheme']
