laravel 8 - 返回基于数组的用户角色

Question

I am using Metronic 8 admin dashboard template for laravel.

The developer made the nav menu as array:

<?php
return array(
    // Main menu
    'main' => array(
        //// Dashboard
        array(
            'title' => 'Dashboard',
            'path' => '',
            'icon' => theme()->getSvgIcon("demo1/media/icons/duotune/art/art002.svg", "svg-icon-2") ,
        ) ,
    )
) 

If you want to add a new nav item, just add an object inside the array.

I am currently using Spatie user roles & permissions. According to their docs, I can use blade directives like this:

@can('permission name')
test
@endcan

OR

@role('role name') test @endrole

Unfortunately, the menu.php is a plain php config file and not a blade. How can I use spatie to hide nav items based on user role?

You need to change configs runtime, in Controller or in Middleware or even in Provider, depending on your needs. You need to do something like:

$navs = config('config.global.menu');
if(auth()->user()->can('permission name')){
    $navs[] = 'nav item';
    config([
        'config.global.menu' => $navs
    ]);
}

You can create a new listener and bind Illuminate\Auth\Events\Login event to it in EventServiceProvider . I've named this event as ModifyMetronicMenu .

protected $listen = [
        Login::class=>[
            ModifyMetronicMenu::class
        ]
    ];

ModifyMetronicMenu listener

namespace App\Listeners;

class ModifyMetronicMenu
{
    public function handle($event)
    {
        $newMenu = array_filter(config('menu.main'),function ($item){
            return \Auth::user()->can(data_get($item,'title'));
        });

        // Update the menu config file
        config(['menu.main'=>$newMenu]);
    }
}

As you can see, I have filtered menu and have updated the config. Notice that the condition that I wrote in the array_filter is not correct and you should tune it base on your needs.
