将循环从 php 转换为 twig

Question

I want to change the command from php to twig:

<?php for($__i = 0; $__i < sizeof($s_opts); $__i++) { ?>

<option value="<?php echo $s_opts[$__i]['id']; ?>"><?php echo $s_opts[$__i]['name']; ?></option> 

<?php } ?>

Answer 1

Here's one way of doing this

{% for opt in s_opts %}
    <option value="{{ opt.id }}">{{ opt.name }}</option> 
{% endfor %}
