Laravel MySQL多行插入跳过现有记录

Question

我有2个多重数组，我循环遍历以在数据库中插入新值，但是当我添加验证时，当条件为true时，循环终止，其余查询不会被执行

{
initialRouteName: 'Home',
drawerPosition: 'left',
contentComponent: withUserContext(CustomDrawerContentComponent),
drawerOpenRoute: 'DrawerOpen',
drawerToggleRoute: 'DrawerToggle',
drawerCloseRoute: 'DrawerClose',
style:{
  drawer: {width:200, shadowColor: '#000000', shadowOpacity: 0.8, shadowRadius: 3},
    main: {paddingLeft: 3}
},
contentOptions: {
  activeTintColor: "white",
  activeBackgroundColor: 'transparent',
  inactiveTintColor: '#c5e6fc',
  inactiveBackgroundColor: 'transparent',
  labelStyle: {
    fontSize: 15,
    marginLeft: 10,
    },
  },
}

我希望其他部分将跳过它们，然后运行其余所有查询
