与Twig相交两个数组 [英] Intersect two arrays with Twig

问题描述

我有两个要交集的数组.我得到了这两个数组:

I have two arrays which i'd like to intersect. I got these two arrays:

{{dump(array1)}}

{{ dump(array1) }}

array(6) {
  [0]=>
  array(2) {
    ["id"]=>
    int(121)
    ["text"]=>
    string(3) "uno"
  }
  [1]=>
  array(2) {
    ["id"]=>
    int(122)
    ["text"]=>
    string(3) "dos"
  }
  [2]=>
  array(2) {
    ["id"]=>
    int(123)
    ["text"]=>
    string(4) "tres"
  }
  [3]=>
  array(2) {
    ["id"]=>
    int(124)
    ["text"]=>
    string(6) "cuatro"
  }
  [4]=>
  array(2) {
    ["id"]=>
    int(125)
    ["text"]=>
    string(5) "cinco"
  }
  [5]=>
  array(2) {
    ["id"]=>
    int(126)
    ["text"]=>
    string(4) "seis"
  }
}

{{dump(array2)}}

{{ dump(array2) }}

array(3) {
  [0]=>
  array(2) {
    ["id"]=>
    int(124)
    ["text"]=>
    string(6) "cuatro"
  }
  [1]=>
  array(2) {
    ["id"]=>
    int(125)
    ["text"]=>
    string(5) "cinco"
  }
  [2]=>
  array(2) {
    ["id"]=>
    int(126)
    ["text"]=>
    string(4) "seis"
  }
  [3]=>
  array(2) {
    ["id"]=>
    int(127)
    ["text"]=>
    string(5) "siete"
  }
}

我希望我的第三个数组具有这样的结果:

And i want my third array to have a result like this:

array(3) {
  [0]=>
  array(2) {
    ["id"]=>
    int(124)
    ["text"]=>
    string(6) "cuatro"
  }
  [1]=>
  array(2) {
    ["id"]=>
    int(125)
    ["text"]=>
    string(5) "cinco"
  }
  [2]=>
  array(2) {
    ["id"]=>
    int(126)
    ["text"]=>
    string(4) "seis"
  }
}

问题是:如何在树枝中使用简单的滤镜将它们相交?

The question is: How do I intersect them using a simple filter in twig?

推荐答案

更好的解决方案是在执行输出之前，将它们在我的控制器或服务中与php相交:

Better solution was to intersect them in my controller or service with php before doing an output:

array_intersect($array1, $array2);

Twig打算在模板中显示数据，而无需像@sjagr在其评论中建议的那样进行过多处理.

Twig is intended to display data in a template without doing too much processing as @sjagr suggested in his comment.
