symfony 2 twig limit the length of the text and put three dots

Question

How can I limit the length of the text, e.g., 50, and put three dots in the display?

{% if myentity.text|length > 50 %}

{% block td_text %} {{ myentity.text}         


        

Answer 1

I wrote this simple marco for the same purpose, hope it helps:

{%- macro stringMaxLength(str, maxLength) -%}
    {%- if str | length < maxLength -%}
        {{ str }}
    {%- else -%}
        {{ str|slice(0, maxLength) }}...
    {%- endif -%}
{%- endmacro -%}

Usage Example #1 (Output: "my long string here ..."):

{{ _self.stringMaxLength("my long string here bla bla bla la", 20) }}

Usage Example #2 (Output: "shorter string!"):

{{ _self.stringMaxLength("shorter string!", 20) }}
