Constants Help - El Forum - 10-14-2010

I've been trying to figure out how to use the constants.php file to load simple global variables that i need access to application wide but I can't figure out how to use it.

I tried adding to constants.php

Code:
$test_var = "HOPE YOU CAN SEE THIS!";

and tried using it on a view page

Code:
&lt;?php echo $test_var; ?&gt;

But all I got was a undefined variable error.

Can someone point me in the right direction?

That is not a constant, that's a normal variable. If you want to make it a constant:

Code:
define('TEST_VAR', 'HOPE YOU CAN SEE THIS!');

is there a different way to call TEST_VAR?

I tried echo'ing it and it didn't work.
