UDTs are being silly

[Cobby]

Hi all,

Here is my problem.

If I have a tag called {page} and its contents is:

Code: Select all

$p = "1";
$page[$p] = "This is page ".$p;
$p++;
echo $page[1];
echo $page[2];

It will output:
This is page 1This is page 2

But if I put $p into a separate tag, so I hade
{p}

Code: Select all

$p = "1";

and

{page}

Code: Select all

$page[$p] = "This is page ".$p;
$p++;
echo $page[1];
echo $page[2];

If that happens it will only output:
This is page 1

I am entering {p}{page} into the page, so that is correct.

Why does it only output 1 page when I set $p in its own tag?

Does tags not recognize the value of variable from another tag?

Cheers,
Cobby

it's not being silly, it's a matter of scope.  if you want to access variables from one UDT in another, you will need to make that variable global in scope.

Thanks for that. Much appreciated
