How can I use break or continue within for loop in Twig template?

Question

I try to use a simple loop, in my real code this loop is more complex, and I need to break this iteration like:

{% for post in posts %}
    {% i         


        

Answer 1

From docs TWIG docs:

Unlike in PHP, it's not possible to break or continue in a loop.

But still:

You can however filter the sequence during iteration which allows you to skip items.

Example 1 (for huge lists you can filter posts using slice, slice(start, length)):

{% for post in posts|slice(0,10) %}
    
{{ post.heading }}
{% endfor %}

Example 2:

{% for post in posts if post.id < 10 %}
    
{{ post.heading }}
{% endfor %}

You can even use own TWIG filters for more complexed conditions, like:

{% for post in posts|onlySuperPosts %}
    
{{ post.heading }}
{% endfor %}
