Question

如何用Laravel替换$ _GET。我试图访问此href参数。我知道在标准PHP中你执行$ _GET请求后跟SQL删除查询语句。在Laravel，它更加困难，因为它涉及控制器/路线。我在ProjectsController中有一个destroy路由。以下链接是我将鼠标悬停在链接上时显示的内容。我得到了Jquery的id并传递了它，但问题是我希望它在点击这个链接时从数据库中删除项目。

<a href="projects/delete=31"> delete</a>

控制器：

<?php

namespace App\Http\Controllers;

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

class ProjectsController extends Controller
{



    public function destroy($id){


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

        $request->input('delete'); 

        $project->delete();

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

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

    }

}

Answer 1

试试这个：

Route::get('projects/delete/{id}', 'ProjectsController@destroy')->where('id', '[0-9]+');

并更新你的href：

<a href="projects/delete/31"> delete</a>

它会像这样工作。您也可以删除该行：$request->input('delete');

Answer 2

更改

<a href="projects/delete=31">delete</a> // this is wrong

到

Approch 01

<a href="projects?delete=31">delete</a>

将路线设为

Route::get('projects', 'ProjectsController@destroy');

将ProjectsController设置为

class ProjectsController
{
    public function destroy()
    {
        $delete = request()->get('delete');
    }
}

Approch 02

<a href="projects/delete/31">delete</a>

将路线设为

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

将ProjectsController设置为

class ProjectsController
{
    public function destroy($id) // $id = 31
    {
        // your code
    }
}

请参阅routing和controllers以掌握它们。

Answer 3

将链接更改为：

<a href="/projects?delete=31"> delete</a>

确保路线如下：

Route::get('projects', ....

然后，您可以在控制器，模型等中使用request('delete')访问此参数。

Answer 4

也许你可以这样试试

<a href="{{ asset('projects/delete/{id}') }}">delete</a>

并设置路线

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

关于ProjectsController中的删除功能

public function delete($id)
{
    $projects = projects::find($id);
    $projects->delete();
    return redirect('/yourEditPage');
}

希望这可以帮到你！

Answer 5

其他答案涵盖了如何通过路由访问get参数，这确实可以回答您的原始问题。

但是，我会建议您在删除内容时遵循restful模式（使用DELETE方法）。在laravel中它非常简单。

路线

Route::delete('projects/{project}', 'ProjectsController@destroy')->name('projects.destroy');

控制器方法

public function destroy(Project $project) {
    $project->delete();
    Session::flash('success', 'The project was successfully deleted!');
    return redirect()->route('projects.index');
}

模板

<form action="{{route('projects.destroy', ['project' => $project->id])}}" method="POST">
{{method_field('DELETE')}}
{{csrf_field()}}

<button type="submit">Delete</button>
</form>
