Global Variable

[eluser]jon74[/eluser]
Hi All,

I am hoping to define a global variable in my controllers that can then be accessed from my Models and core files (e.g. DB_active_rec). I've tried using a constant, which works- but in certain scenarios I need to redefine the value within my controller which a constant doesn't support.

I've also tried defining a global variable in the controller class, but it isn't available in the models/core files.

Any pointers or suggestions would be greatly appreciated.

Thanks

I use the config class for those cases.

Code:

$this->config->set_item('item_name', 'item_value');

After setting an config item anywhere in your application its global accessable.

Code:

$item_value = $this->config->item('item_name');
