Laravel where子句在多个orWhere子句之后不起作用？

Question

我正在查询具有型号名称和类型的车辆，但是在添加orWhere之后，这些where子句不在末尾。 当我评论或删除这些orWhere子句时，它便起作用了。

$models = Vehicle::join('vmodels', 'vmodels.vehicle_id', '=', 'vehicles.id')
    ->join('vehicletypes', 'vehicletypes.id', '=', 'vehicles.vehicletype_id')
    ->join('brands', 'brands.id', '=', 'vehicles.make')
    ->join('companies', 'brands.id', '=', 'companies.name')
    ->select('vehicles.slug as vslug', 'brands.name as brandname', 'vehicles.id as vid', 'vmodels.*', 'vehicletypes.name as vtype', 'companies.status as cstatus')
    ->where('brands.name', 'LIKE', "%{$term}%")
    ->orWhere('vmodels.name', 'LIKE', "%{$term}%")
    ->orWhere('vmodels.year', 'LIKE', "%{$term}%")
    ->orWhere('vehicletypes.name', 'LIKE', "%{$term}%")
    ->orWhere('vehicles.model', 'LIKE', "%{$term}%")
    ->where('companies.status', '=', 1 )
    ->where('vmodels.status', '=', 1)
    ->where('vehicles.status', '=', 1)
    ->paginate(30);

将您的orWhere ，

$models = Vehicle::join('vmodels', 'vmodels.vehicle_id', '=', 'vehicles.id')
    ->join('vehicletypes', 'vehicletypes.id', '=', 'vehicles.vehicletype_id')
    ->join('brands', 'brands.id', '=', 'vehicles.make')
    ->join('companies', 'brands.id', '=', 'companies.name')
    ->select('vehicles.slug as vslug', 'brands.name as brandname', 'vehicles.id as vid', 'vmodels.*', 'vehicletypes.name as vtype', 'companies.status as cstatus')
    ->where(function($query) use($term){
        $query->where('brands.name', 'LIKE', "%{$term}%")
            ->orWhere('vmodels.name', 'LIKE', "%{$term}%")
            ->orWhere('vmodels.year', 'LIKE', "%{$term}%")
            ->orWhere('vehicletypes.name', 'LIKE', "%{$term}%")
            ->orWhere('vehicles.model', 'LIKE', "%{$term}%");
    })
    ->where('companies.status', '=', 1 )
    ->where('vmodels.status', '=', 1)
    ->where('vehicles.status', '=', 1)
    ->paginate(30);

如果要使用Laravel查询构建器为SQL查询模拟AND / OR语句，则应执行以下操作：

((A or B) and (C or D)) or (E)

ModelName::join(...)->join(...)
           ->where(function($query){
               $query->where( A )
               ->orWhere( B )
           })
           ->where(function($query){
               $query->where( C )
               ->orWhere( D )
           })->orWhere( E )

How about this one 
  $models = Vehicle::join('vmodels', 'vmodels.vehicle_id', '=', 'vehicles.id')
    ->join('vehicletypes', 'vehicletypes.id', '=', 'vehicles.vehicletype_id')
    ->join('brands', 'brands.id', '=', 'vehicles.make')
    ->join('companies', 'brands.id', '=', 'companies.name')
    ->select('vehicles.slug as vslug', 'brands.name as brandname', 'vehicles.id as vid', 'vmodels.*', 'vehicletypes.name as vtype', 'companies.status as cstatus')
    ->where('brands.name', 'LIKE', "%{$term}%")
    ->where('companies.status', '=', 1 )
    ->where('vmodels.status', '=', 1)
    ->where('vehicles.status', '=', 1)
    ->orWhere(function($query) use ($term){
      $query->where('vmodels.name', 'LIKE', "%{$term}%")
             ->where('vmodels.year', 'LIKE', "%{$term}%")
             ->where('vehicletypes.name', 'LIKE', "%{$term}%")
              ->where('vehicles.model', 'LIKE', "%{$term}%")
    })   
    ->paginate(30);
