Question

我有这个名为 $ box_items 的laravel集合。

Collection {#320 ▼
  #items: array:3 [▼
    0 => array:6 [▼
      "img_alt" => "<span>Original</span> gifts"
      "class" => "personalised-gifts"
      "elements" => array:2 [▼
        0 => array:2 [▼
          "id" => 2638
          "type" => "ARTICLE"
        ]
        1 => array:2 [▼
          "id" => 2100
          "type" => "ARTICLE"
        ]
      ]
    ]
    1 => array:5 [▼
      "img_alt" => "<span>Love</span> gifts"
      "class" => "love-gifts"
      "elements" => array:3 [▼
        0 => array:2 [▼
          "id" => 1072
          "type" => "CATEGORY"
        ]
        1 => array:2 [▼
          "id" => 6186
          "type" => "ARTICLE"
        ]
        2 => array:2 [▼
          "id" => 1028
          "type" => "CATEGORY"
        ]
      ]
    ]

另一方面，我有另一个名为 $ elements 的集合，这个 $ elements 集合有关于 $ box_items中'element'字段的额外信息收藏。

这是我的 $ elements 集合：

array:5 [▼
   0 => {#313 ▼
      +"type": "ARTICLE"
      +"name": "Ceramic Mug"
      +"resource_id": "2638"
      +"seo": {#314 ▶}
  }

  1 => {#323 ▼
    +"type": "CATEGORY"
    +"name": "Personalised Blankets"
    +"category": {#325 ▼
      +"id": 1072
      +"gallery_id": null
      +"final": true
    }
    +"seo": {#326 ▶}
  }

  2 => {#327 ▼
      +"type": "ARTICLE"
      +"name": "Circle Cushion"
      +"resource_id": "2100"
      +"seo": {#328 ▶}
  }

  3 => {#329 ▼
      +"type": "ARTICLE"
      +"name": "Book"
      +"resource_id": "6186"
      +"seo": {#330 ▶}
  }

  4 => {#341 ▼
    +"type": "CATEGORY"
    +"name": "Gifts for men"
    +"category": {#342 ▼
      +"id": 1028
      +"gallery_id": null
      +"final": false
    }
    +"seo": {#343 ▶}
  }

]

我想用 $ box_items 元素字段替换 $ elements CATEGORIES和ARTICLES。

我想要这个最终结果：

Collection {#320 ▼
  #items: array:3 [▼
    0 => array:6 [▼
      "img_alt" => "<span>Original</span> gifts"
      "class" => "personalised-gifts"
      "elements" => array:2 [▼
        0 => {#313 ▼
            +"type": "ARTICLE"
            +"name": "Ceramic Mug"
            +"resource_id": "2638"
            +"seo": {#314 ▶}
        }
        2 => {#327 ▼
            +"type": "ARTICLE"
            +"name": "Circle Cushion"
            +"resource_id": "2100"
            +"seo": {#328 ▶}
        }
      ]
    ]
    1 => array:5 [▼
      "img_alt" => "<span>Love</span> gifts"
      "class" => "love-gifts"
      "elements" => array:3 [▼
         0 => {#323 ▼
          +"type": "CATEGORY"
          +"name": "Personalised Blankets"
          +"category": {#325 ▼
            +"id": 1072
            +"gallery_id": null
            +"final": true
          }
          +"seo": {#326 ▶}
        }
        1 => {#329 ▼
            +"type": "ARTICLE"
            +"name": "Book"
            +"resource_id": "6186"
            +"seo": {#330 ▶}
        }
        2 => {#341 ▼
          +"type": "CATEGORY"
          +"name": "Gifts for men"
          +"category": {#342 ▼
            +"id": 1028
            +"gallery_id": null
            +"final": false
          }
          +"seo": {#343 ▶}
        }
      ]
    ]

编辑：行中的错误if（$ article_element ['id'] == $ extra_element-＆gt; category-＆gt; id）;

foreach($articles_rows as &$article)
        {

           foreach($article['elements'] as &$article_element)
           {

              foreach($cats_and_arts as $extra_element)
              {

                if($extra_element->type == 'CATEGORY')
                {

                    if($article_element['id'] == $extra_element->category->id)//Undefined index: id
                    {

                         $article_element = (array)$extra_element;
                    }
                }

                if($extra_element->type == 'ARTICLE')
                {

                    if($article_element['id'] == $extra_element->article->id)
                    {

                         $article_element = (array)$extra_element;

                    }
                }

              }
           }
         }
            dd($articles_rows);

试一试。它应该适合你。

foreach($box_items as &$box){
   foreach($box["elements"] as &$box_element){
      foreach($elements as $element){
         if($box_element->id == $element->id){
            $box_element = $element;
         }
      }
   }
 }

合并两个Laravel集合元素并替换
