Twig Array to string conversion
Solution 1
You shouldn't really be building complex data structures inside of Twig templates. You can achieve the desired result in a more idiomatic and readable way like this:
{% for status in status_info %}
<a href="{{ status.link }}" title="{{ status.title }}">{{ status.display }}</a>
{% if not loop.last %}|{% endif %}
{% endfor %}
Solution 2
info is an array, so you should simple write
{{ info|join(', ') }}
to display your info array.
[info] is a array with one value : the array info.
Solution 3
You can user json_encode for serialize array as strig, then show pretty - build in twig
{{ array|json_encode(constant('JSON_PRETTY_PRINT')) }}

This is probably relatively easy to do, but I'm new to twig and I'm frustrated.
I'm adapting code from this answer: https://stackoverflow.com/a/24058447
the array is made in PHP through this format:
$link[] = array( 'link' => 'http://example.org', 'title' => 'Link Title', 'display' => 'Text to display', );
Then through twig, I add html to it, before imploding:
<ul class="conr"> <li><span>{{ lang_common['Topic searches'] }} {% set info = [] %} {% for status in status_info %} {% set info = info|merge(['<a href="{{ status[\'link\'] }}" title="{{ status[\'title\'] }}">{{ status[\'display\'] }}</a>']) %} {% endfor %} {{ [info]|join(' | ') }} </ul>
But I'm getting:
Errno [8] Array to string conversion in F:\localhost\www\twig\include\lib\Twig\Extension\Core.php on line 832
It's fixed when I remove this line, but does not display:
{{ [info]|join(' | ') }}
Any ideas how I can implode this properly?
** update **
Using Twig's dump function it returns nothing. It seems it's not even loading it into the array in the first place. How can I load info into a new array.
