I want to find substring of the string or check if there is no such substring using Twig. On the words, I need analogue of 'strstr' or 'strpos' in php. I googled and searched this issue in stackoverflow but nothing found. Does someone know how to solve this problem?

    Nothing found, really? When I google Find substring in the string in TWIG, I get a first hit that looks really good. I don't think it's going to get any better than that.

  • Please follow the ask advice you needed to confirm before posting any question. Keep in mind that only you want something and you ask yourself how it is programmed does not qualify as a programming question per-se.

  • Pekka, thanks for your link but it isn't exactly what i found. strstr and strpos lets find positions of substring in the string or return false if there is no such substring. It is not similar with strpos.

    If you don't find what you want, you can always do it yourself.

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

    Is it possible to use this inside an if statement?

    Great :) I used it to figure out the current route: <li class="{% if 'gew_team_default_' in app.request.get('_route') %}active{% endif %}">

    Is it affected by slashes or special characters? I am trying to do is find /some-link in some-doma.in/some-link...

    Just for completeness, the syntax for testing whether a substring is not present is: {% if 'needle' not in haystack %}
