Twig Array to string conversion
提问by Chris98
This is probably relatively easy to do, but I'm new to twig and I'm frustrated.
这可能相对容易做到,但我是树枝的新手,我很沮丧。
I'm adapting code from this answer: https://stackoverflow.com/a/24058447
我正在改编这个答案的代码:https: //stackoverflow.com/a/24058447
the array is made in PHP through this format:
该数组是通过这种格式在 PHP 中制作的:
$link[] = array(
'link' => 'http://example.org',
'title' => 'Link Title',
'display' => 'Text to display',
);
Then through twig, I add html to it, before imploding:
然后通过树枝,我在爆炸之前向它添加 html:
<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:
但我得到:
Errno [8] Array to string conversion in F:\localhost\www\twig\include\lib\Twig\Extension\Core.php on line 832
Errno [8] 832 行 F:\localhost\www\twig\include\lib\Twig\Extension\Core.php 中的数组到字符串的转换
It's fixed when I remove this line, but does not display:
删除此行时已修复,但不显示:
{{ [info]|join(' | ') }}
Any ideas how I can implode this properly?
有什么想法可以正确地内爆吗?

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.
使用 Twig 的转储函数,它什么都不返回。似乎它甚至没有首先将它加载到数组中。如何将信息加载到新数组中。

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:
你真的不应该在 Twig 模板中构建复杂的数据结构。您可以像这样以更惯用和可读的方式实现所需的结果:
{% for status in status_info %}
<a href="{{ status.link }}" title="{{ status.title }}">{{ status.display }}</a>
{% if not loop.last %}|{% endif %}
{% endfor %}

info is an array, so you should simple write
info 是一个数组,所以你应该简单地写
{{ info|join(', ') }}
to display your info array.
显示您的信息数组。
[info] is a array with one value : the array info.
[info] 是一个具有一个值的数组:数组信息。

You can user json_encode for serialize array as strig, then show pretty - build in twig
您可以使用 json_encode 将数组序列化为 srig,然后显示漂亮 - 在树枝中构建
{{ array|json_encode(constant('JSON_PRETTY_PRINT')) }}
