laravel 引入模板:
1.return view('admin.login');
2.return view('admin.add',['data'=>$data]);
获取数据:
$request->input('name');
查询
use DB;
$res = DB::table('user')->where('name',$name)->first();
$res2 = DB::table('user')->where('name',$name)->where('pass',$pass)->first();
$data = DB::table('order')->where('name','like','%'.$name.'%')->paginate(10);
$data1 = DB::table('order')->where('name','like','%'.$name.'%')->where('status',0)->paginate(10);
$data = DB::table('detail')->where('orderid',$id)->get();
$review = DB::table('review')->where('goodsid',$v->goodsid)->where('orderid',$order->id)->value('review');
$data = DB::table('type')->select(DB::raw("*,concat(path,',',id) as paths"))->where('status','1')->orderBy('paths')->get();
$res = DB::table('type')->where('pid',$v->id)->first();
修改:$res = DB::table('order')->where('id',$id)->update(['status' => 1]);
新增:DB::table('type')->insert($data);
转向:return redirect("/index");返回提示:return back()->with('mess','密码错误');
$request->session()->forget('name');
laravel sql
1.插入数据
DB::insert('insert into test (id, name, email, password) values (?, ?, ? , ? )',[1, 'Laravel','laravel@test.com','Laravel']);
2.查询语句
$user = DB::select('select * from test where id = ?', [1]);
//我们还 可以看到在执行查询的时候使用了参数绑定,以避免SQL注入。除此之//外还可以使用命名绑定:
$user = DB::select('select * from test where id = :id', [':id'=>1]);
3.更新语句
$resule = DB::update('update test set name="laraveltest" where name = ?', ['laravel']);
//此处返回值为影响的行数请注意 不能直接做判断的
if($resule || $resule===0){
//成功的提示语
return true;
}else{
//失败的提示语
return false;
}
4.删除语句
$deleted = DB::delete('delete from test');
