我在Symfony2项目中正在研究Twig的模板。我需要定义一个二维数组。我试过了
{% set fields = { {'name': 'description', 'value': '1'}, { 'name': 'abc', 'value': '2'}, { 'name':'tags', 'value': '3'} } %}
But I'm getting
但我得到了
A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses (unexpected token "punctuation" of value "{" in ABundle:XYZ:edit_a_page.html.twig at line 51
Not sure what is wrong with the above code.
不确定上面的代码有什么问题。
What is the right syntax to set a 2 dimensional array in twig?

In Twig, arrays are marked with [], and hashes with {}. A hash is a key-value pair with explicit keys (strings or integers), an array is simply a set of values without any explicitly defined keys (they will be indexed numerically).
在Twig中，数组用[]标记，哈希用{}标记。散列是具有显式键（字符串或整数）的键值对，数组只是一组没有任何明确定义键的值（它们将以数字方式索引）。
In order to use a hash, you MUST provide a key for each element.
为了使用哈希，你必须为每个元素提供一个键。
So, what you want is probably {% set fields = [ {'name': 'description', 'value': '1'}, { 'name': 'abc', 'value': '2'}, { 'name':'tags', 'value': '3'} ] %}
那么，你想要的可能是{％set fields = [{'name'：'description'，'value'：'1'}，{'name'：'abc'，'value'：'2'}，{ 'name'：'tags'，'value'：'3'}]％}

You can do it like this {% set foo = {"adjuster_list": {"id": "1", "name": "Joe Smith"}} %}
你可以这样做{％set foo = {“adjuster_list”：{“id”：“1”，“name”：“Joe Smith”}}％}
