Twig - 如何循环特定次数

Question

I need to be able to generate the links certain number of times (stored in int variable)Is there a way to do it out of the box with twig's for loop?

{% for i in numberOfLoops %}
    {{ i }}. Some data
{% endfor %}

The above example do not work. I googled it but did not find actual solution. Any support would be very appreciated.

EDIT: I also tried:

{% set k = 10 %}
{% for i in 0..k %}
    {{ i }}
{% endfor %}

but this generates an exception:

com.lyncode.jtwig.exception.ParseException: Wrong binary operation syntax
Explanation: Input position (line 15, pos 27):
        {% for i in 0..k %}
                      ^

Answer 1

I found the working example:

{% set k = 10 %}
{% for i in range(1, k) %}
    {{ i }}
{% endfor %}

Source: http://twig.sensiolabs.org/doc/templates.html (not very intuitive to find indeed).

Answer 2

I already had a loop in place to iterate over, I solved this for myself with the slice filter.

{% for link in links|slice(0, 12) %}

Answer 3

Try this:

{% set k = 10 %}
{% for i in 0..k %}
    {{ i }}
{% endfor %}
