尝试稍微重构控制器：

public function Projectaction(Request $request)
{
    $query = $request->get('query');

    if ($query == 'All') {
        $portfolio = DB::table('category')
            ->join('projects', 'category.id', '=', 'projects.Category_id')
            ->select('projects.*', 'category.*')
            ->get();
    } else {
        $portfolio = DB::table('category')
            ->join('projects', 'category.id', '=', 'projects.Category_id')
            ->select('projects.*', 'category.*')
            ->where('category.category_name', $query)
            ->get();
    }

    return Response::json([
        'response' => true,
        'html' => View::make('front_end/project', ['portfolio' => $portfolio])->render(),
    ]);
}
