如何在Laravel的同一张表中插入一对多关系多数据? [英] How do I insert one to many relational multi data to same table in Laravel?

问题描述

我的表结构是: id | parent_id |姓名. 我的菜单模型一对多关系是:

My table structure is: id | parent_id | name. My Menu model one to many relationship is:

          public function childMenus() { 
          return $this->hasMany( ‘App\Menu’, ’parent_id’); 
          } 

         public function parentMenus() {
         return $this->belongsTo(‘App\Menu’, ‘parent_id’); 
         }  

我正在创建带有子菜单的菜单.例如，我必须设置具有三个子菜单的父菜单".为此，我创建了一个具有四个输入字段的表单.

I am creating menus with sub menus.For example I have to set 'Parent Menu' with three child menus.For this I have created a form with four inputs field.

<form>
     <input type="text" name="parent">
     <input type="text" name="child[]">
     <input type="text" name="child[]">
     <input type="text" name="child[]">
     </form>

现在我想同时保存父菜单及其子菜单.我试图将它们保存在数组中，但是在Laravel中不起作用. 也请解释什么是保存此数据的控制器方法. 预先感谢
