laravel 关联关系 自定义分页(还是采用与laravel自带的样式相同)

1,laravel自带的分页:

\vendor\laravel\framework\src\Illuminate\Pagination\LengthAwarePaginator.php

运用这个方法:

/** * Create a new paginator instance. * * @param  mixed  $items * @param  int  $total * @param  int  $perPage * @param  int|null  $currentPage * @param  array  $options (path路径, query执行, fragment, pageName) * @return void */public function __construct($items, $total, $perPage, $currentPage = null, array $options = []){    foreach ($options as $key => $value) {        $this->{$key} = $value;    }    $this->total = $total;    $this->perPage = $perPage;    $this->lastPage = (int) ceil($total / $perPage);    $this->path = $this->path != '/' ? rtrim($this->path, '/') : $this->path;    $this->currentPage = $this->setCurrentPage($currentPage, $this->pageName);    $this->items = $items instanceof Collection ? $items : Collection::make($items);}

2,我的controller

public function index(Request $request) {        $search=$request->input('search');        $page = $request->has('page')?$request->input('page'):1;        $paginate = 15;

//搜索功能        if($request->has('search')){            $search=$request->input('search');            $count = Goods::where('name', 'like', '%' . $search . '%')->count();        }else{            $count = Goods::count();//总数        }

//计算一页显示几条数据        $total_page = ceil($count / $paginate);        $temp = [];        for($i=0;$i<$count;$i=$i+$paginate){            $temp[] = $i;        }        if($request->has('search')){            $search=$request->input('search');            $goods = Goods::where('name', 'like', '%' . $search . '%')->offset($temp[$page - 1])->limit($paginate)->get();        }else{            $goods = Goods::offset($temp[$page - 1])->limit($paginate)->get();        }

//laravel的关联关系,注意modal            $data = [];            foreach($goods as $key=>$v){                //dump($v->goodsclass);                $data[$key]['id'] = $v->id;                $data[$key]['name'] = $v->name;                $data[$key]['product_code'] = $v->product_code;                $data[$key]['class_name'] = $v->goodsclass->class_name;                $data[$key]['nums'] = $v->goodsNexus->count();                $data[$key]['price'] = $v->price;            }//dd($data);

//传参数给\vendor\laravel\framework\src\Illuminate\Pagination\LengthAwarePaginator.php//要use Illuminate\Pagination\LengthAwarePaginator;            $goods = new LengthAwarePaginator($data, $count, $paginate, $page, ['path' => '/admin/commodity']);        $goodsClasses = GoodsClass::where('fid', 0)->get();        return view("admin.commodity",[            'goodsClasses'=>$goodsClasses,            'goods'=>$goods,            'search'=>$search,            'total_page'=>$total_page        ]);   }

3,modal:

<?phpnamespace App\Models;use Illuminate\Database\Eloquent\Model;class Goods extends Model{    protected $table='11';    protected $guarded = [];    public function 11(){        return $this->hasMany('App\Models\11', 'id');    }    public function 11(){        return $this->belongsTo('App\Models\111','id');    }    }

public function 11(){    return $this->belongsTo('App\Models\11', 'id');}public function hasChildren(){    return self::where('fid',$this->id)->exists();}public function childrens(){    return self::where('fid',$this->id)->get();}

public function 11() {    return $this->belongsTo('App\Models\11','id');}

4,view

@foreach($goods as $good)<tr>    <td>{{$good['id']}}</td>
