The idea is that I’m fetching table values (also caching it) and made a SettingServiceProvider to be able to access it as a configuration variable later on.
First, we need to create Setting model and migration by following artisan
php artisan make:model Models\Setting -m
Configure for Setting migration file
// database\migration\xxxx_xx_xx_xxxxxx_create_settings_table.php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateSettingsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('settings', function (Blueprint $table) {
$table->smallIncrements('id');
$table->string('name')->unique();
$table->text('value');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('settings');
}
}
Configure for Setting model file
// app\Models\Setting.php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Setting extends Model
{
protected $guarded = [];
}
Run following artisan
php artisan migrate
And create a service provider
php artisan make:provider SettingServiceProvider
We will use cache and set expire time for Setting by bellow code
// app\Provider\SettingServiceProvider.php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Contracts\Cache\Factory;
use App\Models\Setting;
class SettingServiceProvider extends ServiceProvider
{
/**
* Register services.
*
* @return void
*/
public function register()
{
//
}
/**
* Bootstrap services.
*
* @return void
*/
public function boot(Factory $cache, Setting $settings)
{
$settings = $cache->remember('settings', 60, function() use ($settings){
// Laravel >= 5.2, use 'lists' instead of 'pluck' for Laravel <= 5.1
return $settings->pluck('value', 'name')->all();
});
config()->set('settings', $settings);
}
}
Register it into providers section of config/app.php file
// config\app.php
'providers' => [
// ...
App\Providers\SettingServiceProvider::class,
],
Create a controller class for Setting
php artisan make:controller Backend\SettingController
Add following logic code
// app\Http\Controllers\Backend\SettingController.php
namespace App\Http\Controllers\Backend;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Contracts\Cache\Factory;
use App\Models\Setting;
class SettingController extends Controller
{
public function index()
{
$settings = Setting::all();
return view('backend.modules.setting.index', compact('settings'))->withTitle('List of Settings');
}
public function edit(Setting $setting)
{
return view('backend.modules.setting.edit', compact('setting'))->withTitle('Edit a Setting');
}
public function update(Request $request, Factory $cache, Setting $setting)
{
if ($request->isMethod('put')) {
$rules = [
'value' => 'required'
];
$messages = [
'value.required' => 'Value of Setting is required.'
];
$this->validate($request, $rules, $messages);
$setting->value = $request->value;
$setting->save();
// When the settings have been updated, clear the cache for the key 'settings'
$cache->forget('settings');
return redirect()->route('admin.settings.index')->with('success', 'Item has been updated successfully.');
}
}
}
In anywhere, we just only access via the config() helper
config('settings.variable_name')
