How to output multilanguage string inside a multiline variable?

[Juergen]

Hello @ all,

PW offers the opportunity to use multilanguage translateable string.

$text = _x('text', 'noun');

With echoing the text variable you can get the different language translations - so far so good.

But how can I use such a language string inside a multiline variable?

THIS WORKS
$name = _x('Your name', 'Form');
$summary = <<<EOT
My $name is nobody. This is a
text over
multiple lines.
EOT;
echo $summary;

THIS DOESN´T WORK
$summary = <<<EOT
My _x('Your name', 'Form') is nobody. This is a
text over
multiple lines.
EOT;
echo $summary;

I have also tried it with  ${_x('text', 'noun')} and other combinations but I cannot get it to work.

Does anyone know how to use translateable strings inside multiline variables?

Best regards

The heredoc syntax behaves exactly like double-quote strings in a single line. Both do not support calling a function in it, only class methods or anonymous functions, see here for examples: http://stackoverflow.com/questions/10002652/in-php-how-to-call-function-in-string

Edit:

What might work is this, as templates while mostly using local variables are still executed in class context.

$a = <<<EOT
  My {$this->_x('text', 'noun')}
EOT;

Edit2:

You're also using nowdoc instead of heredoc, which does not allow for variable substitution at all, like single-quote strings. See here: http://php.net/manual/de/language.types.string.php#language.types.string.syntax.heredoc

Unfortunately this leads to error 500 in my case.

Instead of the standard syntax for translateable strings I use a function:

//Global translation function
function _t($text, $context, $textdomain = '/site/templates/_strings.php')
{
    return _x($text, $context, $textdomain);
}

and then I call the string like this:

$namelabel             = _t('Your name', 'Form');

Maybe this could be a reason for the error message.

That's exactly the point I meant to convey. You cannot "embed" normal functions in strings. It does only work for class methods or anonymous functions, e.g. everything where a variable (the class or the anonym. func) is involved. 

[Juergen]

OK, I understand. So there is no other way. I have to put the translateable string function into a variable and put this variable into the multiline variable.

Thanks for you help!!

Or you create a class for the job.

Edit:

Also are you sure the first example of your entry post does work? As nowdocs do not substitute variables it shouldn't. If it's not working please correct your entry post.

Yep. Example was not the correct syntax. I have corrected it and I have tested it. I got the correct output.
