twig | Christian Baer – PHP-Developer

In the core symfony / twig do not have a simple truncate-text-function, like substr() in PHP. Therefor you have to activate the Twig-Text-Extension:

// app/config/config.yml
services:
 twig.extension.text:
     class: Twig_Extensions_Extension_Text
     tags:
         - { name: twig.extension }

// app/config/config.yml

services:

twig.extension.text:

class: Twig_Extensions_Extension_Text

tags:

- { name: twig.extension }

Now you can easily truncate as you like:

{{ var.long_description | truncate(50) }}

1	{{ var.long_description \| truncate(50) }}

If you want to preserve whole words, you have to set the 2nd parameter:

{{ var.long_description | truncate(50, true) }}

1	{{ var.long_description \| truncate(50, true) }}

With the 3rd parameter you can override the default seperator ‘…':

{{ var.long_description | truncate(50, true, '.......') }}

1	{{ var.long_description \| truncate(50, true, '.......') }}
