translating strings in template files

[eutervogel]

Hi, 
 

when I try to do that in my template:
 

echo "<h2>" . __("Keine Uploads vorhanden") . "</h2>";

I'm running into an error:  Fatal Error: Uncaught Error: Call to undefined function __()

So I tried to do it this way:
 

echo "<h2>" . $this->_("Keine Uploads vorhanden") . "</h2>";

That doesn't produce an error but the translation is not shown.

I used the first version in other websites before and never had an issue;

PW-Version: 3.0.148

What could be wrong here?

It's hard to tell without getting more informations.

The second call will only work inside a class. The first one should work. 

Where did you place your template file?
Did you add the ProcessWire namespace to your template file?
Could you provide a little more code?

Do you have a namespace declaration in your template?

Thanks guys adding the namespace did it.

But I looked into my other websites a there __() works pretty fine without namespace declaration.

How is that possible?

You probably have disabled "Auto file compiler"?
