如何在php（laravel）中mysql的select语句中添加数组？

Question

我正在尝试在 laravel 的 select 语句中添加数组， 这是示例数据，请查看以下片段，

    $message =["messages"=>[ 
                            ["attachment"=>
                              ["type"=>"template","payload"=>
                                ["template_type"=>"list","top_element_style"=>"large","elements"=>
                                  [
                                    ["title"=>"test","image_url"=> "https://cdn-images-1.medium.com/max/375/0*sepg7sXXe3zcmGvZ.png","subtitle"=>"Soft white cotton t-shirt is back in style","buttons" =>
                                      [
                                        ["type"=>"web_url","url"=>"https://petersapparel.parseapp.com/buy_item?item_id=101","title"=>"buy item"]
                                      ]
                                    ]
                                    ,
                                    ["title"=>"test","image_url"=> "https://cdn-images-1.medium.com/max/375/0*sepg7sXXe3zcmGvZ.png","subtitle"=>"Soft white cotton t-shirt is back in style","buttons" =>
                                       [
                                         ["type"=>"web_url","url"=>"https://petersapparel.parseapp.com/buy_item?item_id=101","title"=>"buy item"]]
                                     ]

                                    ]
                                ]     
                            
                              ]
                           ]
                          ]
              ]; 

当我从 laravel 的数据库中提取时，我只能做直到字幕，我不能做按钮部分

  ["type"=>"web_url","url"=>"https://petersapparel.parseapp.com/buy_item?item_id=101","title"=>"buy item"]

，这是我的尝试，

    $message =["messages"=>[ 
                            ["attachment"=>
                              ["type"=>"template","payload"=>
                                ["template_type"=>"list","top_element_style"=>"large","elements"=>
                                  [
                                    Fabric::orderBy('id', 'DESC')->where('title', 'LIKE', "%$search_term%")
                                     ->select('title','postdate as image_url',"company_name as subtitle"
                                      )->get()
                                    ]
                                ]     
                            
                              ]
                           ]
                          ]
              ]; 

我为每个按钮数组字段都有另一个字段，不知道如何在 select 语句中添加。任何帮助将不胜感激。

Eloquent 模型上的 get 方法返回一个集合，但您似乎正在寻找一个数组。

所以只需像这样修改你的代码：

Fabric::orderBy('id', 'DESC')->where('title', 'LIKE', "%$search_term%")
       ->select('title','postdate as image_url',"company_name as subtitle")
       ->get()->toArray();
