String Modifiers within partials

[nadlig123]

Hello together,

I am trying to do a really basic task. I have a variable called objekttitel and I am trying to modify it with antlers built in modifiers.
My code looks as following:

 {{ if objekttitel | is_empty }}
      {{ 'Kein Titel' }}
 {{ else }}
       {{objekttitel | truncate(30, '...')}}
 {{ /if }}

I get following error message "Modifier [truncate(30, '...')] not found". I have already checked that var objekttitel definitely is a string and i can't really figure out what is missing in piece of code. I have also tried other modifiers such as substring, ... and they all don't work, except of a few like length and also is_empty.

Would really appreciate any help :D

Hey there!

Sounds like the Antlers version is set to regex; that new syntax is only supported with the newer Antlers version. If you need to continue using that version, the docs here will help with passing arguments to modifiers: https://statamic.dev/antlers-legacy#stringshorthand-style

To change the Antlers version, in config/statamic/antlers.php you can set the version entry to runtime:

<?php

return [
    // ...
    'version' => 'runtime',
   // ...
];

If its already set like that, or you still receive the error after the change, you can try clearing the configuration cache using:

php artisan config:clear

If you decide to change the Antlers version, your condition can be simplified to the following:

{{ (objekttitel | trim | truncate(30, '...')) ?? 'Kein Titel' }}
