putting variables inside predefined variables. Possible?

[jtorral]

Normally,

 

I would check for a cookie something like this

 

$_COOKIE['cookie_name']

 

But how can I do this ...

 

$cn = "cookie_name";

$_COOKIE['$cn'];

 

I can't get it to work. Is there a special way of assigning a variable to a global predefined?

 

Thanks

Do like $_COOKIE[$cn] without the quotes around the variable name.

i tried that and it does not work

Okay...

 

How did you try it, and how does it "not work"?

 

Help me help you. It's not like I can see what's going on on your computer, so vague statements like "it does not work" are entirely useless.

i have javascript that sets a cookie when I click on a link.

I then call the function below to check the value of the cookie.

 

I am trying to use variable $div because I have 20 cookies withe the name xxx_div1 through xxx_div20 therefor I try to create the cookie name in the call so ai can minimize code.

 

If i take the function below and replace $divcn with the actual cookie name it works as expected. If I use the variable, it always goes to the else.

 

function checkdivsettings($div) {

  $divcn = "xxx_" . $div;

  if(isset($_COOKIE[$divcn])) {

      $div = $_COOKIE[$divcn];

  } else {

      $div = "block";

  }

  return $div;

}

The proverbial wrong spelling!
