This article mainly introduces the binding operation method of Laravel framework routing and controller. It analyzes the operation steps, implementation methods and related precautions of binding Laravel framework routing and controller in the form of examples. Friends in need can refer to it. Next
The example of this article describes the binding operation method of Laravel framework routing and controller. Share it with everyone for your reference, the details are as follows:
The relationship between routing and controller
The routing file address is in \app\ Http\routes.php, let’s look at two different routes.
Route::get('/', function () {
return view('welcome');
});
Route::get('/hi', function () {
return 'hello world';
});The above are all routes bound to anonymous functions. Although they can return views or strings, the essence is the same.
Route::get('/blog','BlogController@index');
Route::get('/post/{slug}','BlogController@showPost');These two are routes bound to the controller. There are two functions under the controller class BlogController, index and showPost can be called.
So the question is, which one should I choose?
You can't write complex business logic in an anonymous function, so you have to learn to create new controllers.
Route::get('/mvc', 'MyController@hello');
Add a new controller
The controller folder address is in the Laravel folder Next\app\Http\Controllers, we continue to use the artisan console to create a new controller
php artisan make:controller MyController
Then, return to the controller directory, a new MyController.php file is created with the following code:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
class MyController extends Controller
{
//
}We modify the MyController class and create a view at the same time.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
class MyController extends Controller
{
public function hello()
{
return View('myview');
}
}If written like this, it means that once the user accesses URL:laravel/public/mvc, the routing will be handed over to MyController for control The hello function of the controller, the hello function returns the myview view, that is, returns myview.blade.php
Let’s take a look at the code of myview.blade.php
@extends('layouts.app')
@section('content')
<p class="container">
<p class="row">
<p class="col-md-10 col-md-offset-1">
<p class="panel panel-default">
<p class="panel-heading">{{ $d1 }}</p>
<p class="panel-body">
this is my view!
</p>
</p>
</p>
</p>
</p>
@endsection Here{{ $d1 }} hopes to use the value of a variable instead, so we modify the MyController controller to
class MyController extends Controller
{
public function hello()
{
return View('myview',['d1'=>'a1']);
}
}
