1.创建路由

  1. //新闻系统
  2. Route::get('/admins/article/index','Article@index');//文章列表
  3. Route::get('/admins/article/add','Article@add');//文章添加
  4. Route::post('/admins/article/save','Article@save');//文章保存
  5. Route::post('/admins/article/del','Article@del');//删除文章
  6. Route::get('/admins/article/cates','Article@cates');//文章分类
  7. Route::get('/admins/article/add_cate','Article@add_cate');//添加文章分类
  8. Route::post('/admins/article/save_cate','Article@save_cate');//保存文章分类
  9. Route::post('/admins/article/del_cate','Article@del_cate');//删除文章分类
  10. // 上传系统
  11. Route::post('/admins/files/upload_img','Files@upload_img');//文章缩略图上传

2. 创建后台控制器

利用laravel的artisan命令轻松创建

  1. php artisan make:controller admins/Article
  2. php artisan make:controller admins/Files

3. 控制器代码

  1. <?php
  2. namespace App\Http\Controllers\admins;
  3. use App\Http\Controllers\Controller;
  4. use Illuminate\Http\Request;
  5. use Illuminate\Support\Facades\DB;
  6. use Illuminate\Support\Facades\Auth;
  7. class Article extends Controller
  8. {
  9. // 添加新闻
  10. public function add(Request $request)
  11. {
  12. $aid=(int)$request->aid;
  13. $data['article']=DB::table('article')->where('id',$aid)->item();
  14. $data['contents']=DB::table('article_detail')->where('aid',$aid)->item();
  15. $data['cates']=DB::table('article_cate')->lists();
  16. return view('admins/article/add',$data);
  17. }
  18. // 保存新闻
  19. public function save(Request $request)
  20. {
  21. $aid=(int)$request->aid;
  22. $admin=Auth::user();
