php - 通过 Laravel 中的链接 href 传递 id

Question

是否可以通过 Laravel 中的链接 href 传递 id 并显示该页面，如/projects/display/2。

我有这个链接:

<td><a href="{{ url('projects/display', $projects->id) }}" class="btn btn-info">View</a></td>

将鼠标悬停在/projects/display/2 链接上时，它会显示 id。但是每当我点击链接时，我都会收到一条错误消息:

 Sorry, the page you are looking for could not be found.

我有一个名为 projects/display 的 View 设置，以及路由和 Controller 。

路线:

<?php


Route::group(['middleware' => ['web']], function (){

    Route::get('/', 'PagesController@getIndex');

    Route::get('/login', 'PagesController@getLogin');

    Auth::routes();

    Route::get('/home', 'HomeController@index');

    Route::get('/projects/display', 'ProjectsController@getDisplay');

    Route::resource('projects', 'ProjectsController');


});

Controller :

<?php

namespace App\Http\Controllers;

use App\project;
use App\Http\Requests;
use Illuminate\Http\Request;
use Session;

class ProjectsController extends Controller
{

    public function index()
    {



    }


    public function create()
    {
        return view('projects.create');
    }



    public function store(Request $request)
    {
        $this->validate($request, array(

            'name' => 'required|max:200',
            'description' => 'required'
        ));

        $project = new project;

        $project->name = $request->name;
        $project->description = $request->description;

        $project->save();

         Session::flash('success', 'The project was successfully created!');

        return redirect()->route('projects.show', $project->id);


    }


    public function show()
    {
        $project = Project::all(); 

        return view('projects.show')->withProject($project);

    }


    public function edit($id)
    {
        //
    }


    public function update(Request $request, $id)
    {
        //
    }

    public function getDisplay($id){


        $project = Project::find($id);

        return view('projects/display')->withProject($project);

    }





}

您需要将路线更改为:

Route::get('/projects/display/{id}', 'ProjectsController@getDisplay');

然后生成 URL:

{{ url('projects/display/'.$projects->id) }}
