I need to get short weekday names dynamically. But this code in templates doesn't work:

{{$day1 = 'day_' . date( 'w', $timestamp ) . '_short';}}

{lang="$day1"}

Is it possible to do this?

Probably you need something like:

{{$day1 = \IPS\Member::loggedIn()->language()->addToStack( 'day_' . date( 'w', $timestamp ) . '_short' );}}

addToStack or get.

Untested.

Edit: scratch what I said before. What you want is

{lang="{$day1}"}

addToStack is actually the equivalent of lang="".

@HeadStand I tried this, but without success.

@Adriano Faria I get day_2_short string in the output, so I guess the problem is in the second part: how {lang=""} works.

lang makes a call to addToStack. So the question is, do you have a language string called day_2_short?

@HeadStand yes, sure, I have it. As I know, it's a default string.

No, it's a js language string, which means that it doesn't exist in the php scope

Hm... But I can see it in the ACP:

What should I do now?

It will be listed in the ACP because that would display both PHP and JS variables. You'll need to create duplicate strings in your own lang file.

Is there any way to avoid this duplication? I don't want to let the users of my plugin to translate these strings while they are already translated in the System.

So you have a variable $timestamp which, presumably, holds a timestamp right? And you want to show the short form of the day (i.e. "Sun" for Sunday)?

Something like this should work

{expression="\IPS\DateTime::ts( $timestamp )->strFormat( '%a' )"}

 

This doesn't rely on language strings but rather uses the native PHP DateTime object (which is locale aware).
