Dynamic language string name in templates

[motomac]

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?

[motomac]

@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.

[motomac]

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).
