laravel5.4笔记

laravel获取输入数据

获取已知key的数据

public function store(Request $request)

{

    $name = $request->input('name');

$request->path();  //获取请求路径

if ($request->is('admin/*')); //判断是否符合目标路由

$url = $request->url(); //获取请求url

$url = $request->fullUrl();//获取请求url,包含查询字符串

$method = $request->method(); //请求方法

if ($request->isMethod('post'));//判断请求方法

$input = $request->all();//以数组方式获取输入全部数据

}

处理session

$request->session()->put('aa','bb'); //添加
var_dump($request->session()->get('aa')); //获取
$request->session()->forget('aa'); //删除
$request->session()->flush(); //删除全部

Laravel模型操作

引用模型 use IlluminateDatabaseEloquentModel;

设置表 $table = ‘tbname’;

设置主键 $primaryKey = key;

设置非数字主键 $incrementing = true;

取消维护数据记录(时间戳) $timestamps = false;

获取全部数据

$flights = $this->all();

$this::where([])->get();

分页

$this::where([])->orderBy('id','asc')->paginate(15);

增加一定的限制

$flights = AppFlight::where('active', 1)

               ->orderBy('name', 'desc')

               ->take(10)

               ->get();

获取单个数据

$flight = AppFlight::find(1); //使用主键查找

$flight = AppFlight::where('active', 1)->first();

插入一条数据

$this->fill($data);

$this->save();

$flight = new Flight;

$flight->name = $request->name;

$flight->save();

更新数据

$flight = AppFlight::find(1);

$flight->name = 'New Flight Name';

$flight->save();

$sk = $this::find($id);

$sk->update($data);

删除数据

$sk = $this::find($id);

$sk->delete();
