Regex to check for a number in the url using Twig

This wouldnt be a big problem if I had known Twig a little more. Here is my code, I am trying to check whether the url contains number in it.

{% set x = req.path %} {% set matches = x|regex_match('~[\d\.]+$~') %} {% set matches = x|regex_match('~[0-9]*$+~') %}

none of these work

thanks in advance

For complex string comparisons, the matches operator allows you to use regular expressions:

{% if phone matches '/^[\\d\\.]+$/' %}
{% endif %}

So, to check if a string contains a digit with a regex, just use

{% if x matches '/\\d/' %} Do Stuff {% endif %}

Why using Twig for this ? should be more reliable to use the routing functionnalities ?

my_route_to_check: pattern: /my/route/{id} defaults: { _controller: acmeMybundle:myController:myAction, id:0} requirements: id : \d+

here {id} has to be a integer ( with \d+ rules ) otherwise an exception will be triggered.

easier , no ?
