[Problem] echo $number works fine, setvar displays nothing

[ClausVB]

Perhaps I miss something, but this behavior seems strange to me:

Code: [Select]


$number = 2 - 2;

echo $number;



displays 0 like it should be.

Code: [Select]


$number = 2 - 2;

$tmpl-setvar'number', $number;



displays nothing.

Code: [Select]


$number = 2 - 2;

$tmpl-setvar'number', $number;



works fine again.

It's working this way, but why echo and setvar work differently?

Claus

Note:
First encountered in:

Code: [Select]


if $successes_a = $successes_b



$netto = $successes_a - $successes_b;

$winner = A;



else



$netto = $successes_b - $successes_a;

$winner = B;





$tmpl-setvar'netto', $netto; // $netto==0 would display nothing instead of 0

$tmpl-setvar'winner', $winner;



[ClausVB]

By the way ...

$tmpl->setvar('number', 0);

does not work either.

Was this happening within a Loop?

[ClausVB]

No, normal code.

Does it not occur in your enviroment?

Then I will look after my version.

But I think it is 3-0-10.

I see where the problem is.

If you need this urgently you can change the setVar function in vlibTemplate.php yourself.
In the 'else' section you'll see at the end off the if statement it says:

Code: [Select]


if preg_match'/^A-Za-z_+A-Za-z0-9_*$/', $k && $v != null



.. you just need to change the " && $v != null" to " && $v !== null" so it reads:

Code: [Select]


if preg_match'/^A-Za-z_+A-Za-z0-9_*$/', $k && $v !== null



I'll fix this in the next version of vLIB, which should be out soon.
