Php 从Laravel中的pivotParent获取数据
目前我在MySQLvideos中有3个表:关键字、视频_关键字。video_keywords是一个透视表单videos和keywords id、keywords_id、video_id。主要问题是:如何从keywords表接收来自pivotParentname表的数据?目前我只能从视频关键字表中获取关键字id、视频id以及视频表中的所有数据,但无法从关键字表中获取任何内容 在keywords/list.blade.php中转储$keyword->videos将提供输出: [{id:4,youtube\u id:cq2Ef6rvL6g,标题:环境放松休息室放松音乐-基本放松课程1-背景放松音乐-创建时间:2020-01-22 14:39:41,更新时间:2020-01-22 14:39:41,轴心:{关键字\u id:5,视频\u id:4}] BelongToMany返回一个Illumb\Database\Eloquent\Collection实例,它是关键字视频的列表 因此,您可以检索第一个视频的名称,如下所示: 转储$keyword->videos->first->name; 或者,如果要循环浏览视频列表,请执行以下操作: foreach$关键字->视频作为$video{ 转储$video->name; } 您可以在此处阅读更多关于多对多关系的信息:Php 从Laravel中的pivotParent获取数据,php,laravel-5,Php,Laravel 5,目前我在MySQLvideos中有3个表:关键字、视频_关键字。video_keywords是一个透视表单videos和keywords id、keywords_id、video_id。主要问题是:如何从keywords表接收来自pivotParentname表的数据?目前我只能从视频关键字表中获取关键字id、视频id以及视频表中的所有数据,但无法从关键字表中获取任何内容 在keywords/list.blade.php中转储$keyword->videos将提供输出: [{id:4,youtu
