If a variable hasn't been defined, I want to define it (easy question) 1

[krigbert]

Poor assed headline, but it is descriptive

Here's what I have:

define("GOTOO", $_GET['goto']);

if (defined('GOTOO')) {

  }else{
  
  define("GOTOO", 2);
  
}

$goto = GOTOO;

So, if goto is defined (in a link), it gets passed over to the constant GOTOO, which I then see if is defined - if it isn't I set it to be the number 2. After all that I set the variable $goto to the value of the constant GOTOO.

Not all that straightforward, but it works in my mind... but not on the computer

is not very specifc, Do you get any error messages? do the values not get assigned exactly what is not working?

Actually, your call to DEFINE is going to generate a warning when $_GET['goto'] is not set.

I would Check wether $_GET['goto'] is set before using it to define a constant.

So basically,

if ( isset( $_GET['goto'] ) 
   $goto = $_GET['goto'] ; 
else 
   $goto = 2 ;

tried cut and pasting and tried

if ( isset($_GET['goto']) ){

   $goto = $_GET['goto'] ;
   
}else{

   $goto = 2 ;
   
}

But it just doesn't seem to pass it along. "$goto = $_GET['goto'];" alone does pass it along, so I'm guessing it's just a typo :l

huh?

If $_GET['goto'] is set then $goto will get the value.

If $_GET['goto'] is not set then $goto will get a value of 2.

What doesn't pass?

Agh, sorry, nevermind, it was the script that was receiving the value that didn't want to take numbers. That does actually work. Barrels o' thanks.

Try printing out $_GET to see what's happening.
