Laravel错误：路由未定义

Question

Possible duplicate of this . But unable to get the answer in my case.

I need to use a link on my Laravel website, but it keeps resulting in "route not defined" error.

Html:

<ul class="nav navbar-nav">
@auth
    <li>
        <a href="{{ route('add-post') }}">Add post</a>
    </li>
@endauth
</ul>

web.php:

Route::get('/add-post', 'PagesController@add_post');

PagesController:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class PagesController extends Controller
{
    public function add_post()
    {
        return view('add-post');
    }
}

Answer 1

You need to name the route in order to do that:

For example:

Route::get('/add-post', 'PagesController@add_post')->name('add-post);

This is because when you use route('add-post') are are requesting a URL based on the name set in the web.php file

Answer 2

So you basically have two options here. When you use the route function, Laravel is looking for a named route. In order to name a route, you can add ->name('name-of-route-here') at the end of your route definition.

If you don't want to name your route, you can just use the url helper function instead of route , so your code would be url('add-post')

Documentation on named routes: https://laravel.com/docs/5.5/routing#named-routes Documentation on url function: https://laravel.com/docs/5.5/helpers#method-url

Answer 3

Just change this:

<ul class="nav navbar-nav">
   @auth
     <li>
      <a href="{{ url('add-post') }}">Add post</a>
   </li>
   @endauth

web.php:

Route::get('add-post', 'PagesController@add_post');
