Help with smarty template + function

[fredrm]

Hi Folks! I need some help with functions and smarty template.

I have a function like this:

function Test(){
$a = "This is a test.";
}

and I have a Item Template to show this variable on the smarty template, that go like this:

function Unit1Template($sender, $params){
$this->Test();

$template = $params['template'];
$template->_smarty->assign("test", $a);
}

And my Smarty Template is ok, but nothing shows...

debug with die ($a);

Then learn about variable scope on php.net

PHP: Variable scope - Manual

But the question is.

How do I get the $a valeu inside of the Unit1Template?

Because when I debug on die($a), the $a inside of the Unit1Template is equals to NULL.

Thx!

That is why I pointed you to variable scope.

In a nutshell vars are private to their function so they aren't usable unless you do something to make them that way. Declare them global is one way. Another is to return them from the function

PHP Code:

function Test(){
$a = "This is a test.";
return $a;
}

....

$template->_smarty->assign("test", $this->Test());
