获取 controller 中的删除 id 以删除 mysql 记录

Question

I have this in AuthController:

public function DelFunc() {

    if(Auth::check() === true) {
        $deleted = DB::delete('delete from funcionarios where id = ?',[$id]);
    }
    return redirect()->route('admin.login');
}

But I get this error: Undefined variable: id

I have this button in my view:

<a href="../admin/delFunc?id={{$empresa->id}}">
    <button class="btn btn-primary">Delete</button>
</a>

I know my question is simple, but, how can I get the id value on AuthController to delete this record?

I also have this route:

Route::get('/admin/delFunc', [App\Http\Controllers\AuthController::class, 'delFunc'])->name('delFunc');

Answer 1

A bunch of red flags here:

• Why is this going into a controller called AuthController when it is working with a Funcionario object?
• Why direct database queries instead of using Eloquent models?
• You should not be deleting items by GET method, this is very dangerous.
• Authentication is to be done by middleware, not by checking within every controller method.
• And last, your method should also have a more conventional name like destroy .

Route parameters are defined in the route definition with braces like "/admin/delete/{func}" and then bound to objects in the controller method definition.

So, putting all that together, what it should look like is:

<?php

use App\Http\Controllers\FuncionarioController;
use Illuminate\Support\Facades\Route;

Route::middleware("auth")->group(function ($router) {
    $router->delete('/funcionario/{func}', [FuncionarioController::class, 'destroy'])
        ->name('funcionario.destroy');
});

And then in your controller:

<?php

namespace App\Http\Controllers;

use App\Models\Funcionario;

class FuncionarioController extends Controller {

    public function destroy(Funcionario $func)
    {
        $func->delete();
        return redirect()
            ->route('admin.login')
            ->with('success', __('Funcionario deleted'));
    }
}

And your view would look like this, assuming your value is passed in the $id variable:

<form method="post" action="{{ route("funcionario.destroy", $id) }}">
    @method('DELETE')
    @csrf
    <button type="submit">{{ __("Delete") }}</button>
</form>

Instead of [$id] use [request('id')]
