Bug when passing numeric zero to template

Recommended Posts

Hello,

I just found out that,  when passing a (numeric) zero with "$view->myVar=0" to a template then the corresponding template variable $this->myVar is empty, it has no value.

This even occurs when I convert the value to a string: (string) 0

Strings and numeric values other than zero are handled correctly. 

I think this is a bug which should be fixed?!

 

regards, Helmut

you pass it via API to a template or a page? In case of the latter, I can't reproduce that.

What is $view? The PW core does not have the concept of a view that variables are passed to - there are just template files where the API variables are available.

I think this is not a core issue but perhaps you are using some third-party templating module in which case you should raise this in the module's support thread.

Assuming you use TemplateFile ? This works as it should, variables are passed as is:

$tpl = new TemplateFile("_tpl.php");
$tpl->myVar1 = 0;
$tpl->set("myVar2", 1);
$content .= $tpl->render();

in _tpl.php

echo $myVar1;
echo $myVar2;

Outputs: 01

$view is an instance of
