Generally, we cannot use the laravel localization key in its javascript. is that possible to use laravel localization in javascript?

Yes, now you can use laravel localization into laravel, thanks to the rmariuzzo/Laravel-JS-Localization package.

In this tutorial, we will learn how to use laravel localization in javascript, so let's get started.

Install the package

composer require mariuzzo/laravel-js-localization

In your Laravel app go to config/app.php and add the following service provider:

Mariuzzo\LaravelJsLocalization\LaravelJsLocalizationServiceProvider::class

Usage

The Laravel-JS-Localization package provides a command that generates the JavaScript version of all your messages found in app/lang (Laravel 4) or resources/lang (Laravel 5) directory.

Generating JS messages

php artisan lang:js

The resulting JavaScript file will contain all your messages plus messages.js in your public directory.

Link that js file into your main layout.

<script src="{{ asset('messages.js') }}"></script>

Documentation

Getting a message

Lang.get('messages.home');

Getting a message with replacements

Lang.get('messages.welcome', { name: 'Joe' });

Changing the locale

Lang.setLocale('es');

What are UUIDs?

UUIDs stands for Universally Unique Identifiers and are 128 bits values used to uniquely identify some record in our database. UUIDs are represented as a hexadecimal string split into five groups separated by hyphens.UUIDs are universally unique alphanumeric identifiers that are 36 characters long.

Instead of using auto-incrementing integers as your Eloquent model's primary keys, you may choose to use UUIDs instead.

Updating Migration File

It is a very important step to update our migration file, I want to use the UUIDs in my User class so I will make changes to my User’s migration class.

 $table->id();

to this:

$table->uuid('id')->primary();

If you are using a UUID primary key as a foreign key in another table, you need to change the column type to UUID, where the foreign key is defined. from this:

$table->unsignedBigInteger('user_id')->unsigned();

to this:

$table->uuid('user_id');

Using Trait in Our Model Class

you may use the Illuminate\Database\Eloquent\Concerns\HasUuids trait on the model.

use Illuminate\Database\Eloquent\Concerns\HasUuids;
use Illuminate\Database\Eloquent\Model;

class User extends Model
{
  use HasUuids;

  // ...
}

$user = User::create(['name' => 'John','email' => 'john@doe.com']);

$user->id; //72106479-5367-4853-9b44-b8b7a1e94f01

By default, The HasUuids trait will generate "ordered" UUIDs for your models. These UUIDs are more efficient for indexed database storage because they can be sorted lexicographically.

Why use UUIDs over regular IDs?

• UUIDs are safer than using regular numeric IDs because they are not easy to spoof. Regular IDs make it easy to get information about the application, like how many users the application has.
• Using UUID is a great solution for multi-tenancy applications.

I hope you will find this post useful.

How to integrate paypal payment gateway with Laravel / PHP ?

In this tutorial we are going to see to integrate the paypal payment gateway with checkout method using the Laravel.

We are going to use package : https://github.com/srmklive/laravel-paypal

Install the package

composer require srmklive/paypal:~3.0

Publish Assets

php artisan vendor:publish --provider "Srmklive\PayPal\Providers\PayPalServiceProvider"

Set Paypal credentials into config/paypal.php

return [
    'mode'    => env('PAYPAL_MODE', 'sandbox'), // Can only be 'sandbox' Or 'live'. 
    'sandbox' => [
        'client_id'         => env('PAYPAL_SANDBOX_CLIENT_ID', ''),
        'client_secret'     => env('PAYPAL_SANDBOX_CLIENT_SECRET', ''),
        'app_id'            => '',
    ],
    ......
    ......
];

Create Routes

routes/web.php

 Route::get('paypal-onboard', [PaypalController::class, 'onBoard'])->name('paypal.init');
 Route::get('paypal-payment-success', [PaypalController::class, 'success'])->name('paypal.success');
 Route::get('paypal-payment-failed', [PaypalController::class, 'failed'])->name('paypal.failed');

Create Controller

app\Http\Controllers\PaypalController.php

setCurrency('EUR');
        $provider->getAccessToken();
        $data = [
            "intent"              => "CAPTURE",
            "purchase_units"      => [
                [
                    "amount" => [
                        "value"         => 100,
                        "currency_code" => getCurrencyCode(),
                    ],
                ],
            ],
            "application_context" => [
                "cancel_url" => route('user.paypal.failed'),
                "return_url" => route('user.paypal.success'),
            ],
        ];

        $order = $provider->createOrder($data);

        return redirect($order['links'][1]['href']);
    }

    public function failed()
    {
        dd('Your payment has been declend. The payment cancelation page goes here!');
    }

    public function success(Request $request)
    {
        $provider = new PayPal();      // To use express checkout.
        $provider->getAccessToken();
        $token = $request->get('token');

        $orderInfo = $provider->showOrderDetails($token);
        $response = $provider->capturePaymentOrder($token);

        dump($orderInfo);
        dd($response);
    }
}

That's it. Enjoy.

We often listen to the words "Eager Loading" & "Lazy Loading" in Laravel. but maybe some of how still don't know what that actually stands for.

What Lazy Loading means?

I worked with many projects that is developed by some other developers and the common problems in code I found us Lazy Loading queries everywhere.

To understand it more easily let's take one simple example.

Let's say There is Post model and Comments Model.

So basically post->hasMany('comments')

So let's say we are fetching 10 posts and now we want the comments of each post. what we will do is :

$post->comments()->get() (LAZY LOADING)

Lazy loading cause N+1 queries issues as every time we are fetching comments of each post and it will block the execution too for while as its queries from the DB.

What Eager Loading means?

Eager loading is very useful when we are working with large-scale projects. it saves lot's of execution time and even DB queries too :)

Let's take the above example to understand the Eager loading.

$posts = Post::with('comments')->get()

$post->comments (EAGER LOADING)

here when we retrieve the posts at that time we are fetching its comments too on the same query. so when we do $post->comments it will not again do query into DB or not even block execution as the comments are already there in model instance.

So this is how Eager loading saves your time and also prevents N+1 Query.

Hope that helps.

It's 2022 and people are still using the old jquery tables with Laravel. As laravel have the livewire why do we have to use the jquery tables ??

In this tutorial, we are going to use the livewire tables and gonna see the benefits of it.

The main problem I see with Jquery Datatable is :

• Page will flicker when we do any search, as it will fire the server-side query and fetch results
• HTML Appending into JS for action column
• It's not easy to customize the row, we have to write the HTML into JS

The main benefits of using Laravel Livewire tables are:

• After searching results will be quickly updated on-page, without flickering
• As the Livewire table is JS less, Of course, you don't have to append HTML into it. you can do it via blade files :)
• You can easily customize the row and tables view by adding your custom blade views.

How to integrate Bootstrap Livewire tables?

For that we are going to use the following package :

https://github.com/rappasoft/laravel-livewire-tables

Install Package

composer require rappasoft/laravel-livewire-tables

Publish Assets

php artisan vendor:publish --provider="Rappasoft\LaravelLivewireTables\LaravelLivewireTablesServiceProvider" --tag=livewire-tables-config

php artisan vendor:publish --provider="Rappasoft\LaravelLivewireTables\LaravelLivewireTablesServiceProvider" --tag=livewire-tables-views

php artisan vendor:publish --provider="Rappasoft\LaravelLivewireTables\LaravelLivewireTablesServiceProvider" --tag=livewire-tables-translations `

Choosing Bootstrap 5 theme

Into the published config file you can choose/change theme to bootstrap-5

    return [
        /**
        * Options: tailwind | bootstrap-4 | bootstrap-5.
        */
        'theme' => 'bootstrap-5',
    ];

Render the components

    <livewire:members-table />

Create Component

    namespace App\Http\Livewire;

    use App\Models\User;
    use Rappasoft\LaravelLivewireTables\DataTableComponent;
    use Rappasoft\LaravelLivewireTables\Views\Column;

    class MembersTable extends DataTableComponent
    {
        protected $model = User::class;

        public function configure(): void
        {
            $this->setPrimaryKey('id');
        }

        public function columns(): array
        {
            return [
                Column::make('ID', 'id')
                    ->sortable(),
                Column::make('Name')
                    ->sortable(),
            ];
        }
    }

That's It :)

That's it, and you will see the bootstrap-5 Laravel livewire table. it have other lot's of fucntionality too, you can use or disable it as per your need.

What is Laravel?

Laravel is the most popular PHP framework right now to develop web applications, it offers a very easy environment and services for developers.

In this blog, we are going to know about the packages that we must have to use while developing any laravel application.

Best Laravel Packages

Here we are going to see some best and top laravel packages that will help you to optimize your application performance and it's also very useful while doing the development.

IDE Helper

Github: https://github.com/barryvdh/laravel-ide-helper

It's a very helpful package and saves lots of time for the developer.

It will generate the helper file which enables our IDE to provide accurate autocompletion while doing the development.

Laravel Debugbar

Github : https://github.com/barryvdh/laravel-debugbar

This is very helpful when we have to check the page performance, in sense of how many queries are firing on the specific page? , how many models are loading? etc.

We can show the total processing time of the page, and the query results time too. by using that results we can do some refactor to our code and make our application more optimized.

Spatie Medialibrary

Github : https://github.com/spatie/laravel-medialibrary

This package is very useful when we are doing file uploads. also, it allows us to upload files to the s3 (AWS) very easily by changing just the file system driver.

The main functionality it has is it allows us to associate files with the Eloquent models.

Spatie Role Permission

Github : https://github.com/spatie/laravel-permission

It's 2022 and still, lots of developers are using the custom roles/permissions management. they even didn't familiar that this package have capabilities to manage each role/permissions management with a specific Eloquent model too.

We can assign roles or permissions to the user model or even any model. later we can check it via the middleware that this package is providing.

Ziggy

Github : https://github.com/tighten/ziggy

Before using this package you must need to implement the named routes into your laravel application.

Normally people can just provide a hardcoded URL into the JS file while doing the AJAX calls. But with this package, you can use the route we are using in blade files.

This allows us to use the route() helper method in the JS files.

People are quite afraid :), including me :) when it’s about the developing system that works with multi-tenant / multi-database.

In this tutorial, we will implement a multi-tenant system that will create a separate database when the new tenant will create.

Install Package

composer require stancl/tenancy

Then run the following command :

php artisan tenancy:install

Then add the service provider TenancyServiceProvider to your config/app.php file:

/*
 * Application Service Providers...
 */
App\Providers\AppServiceProvider::class,
App\Providers\AuthServiceProvider::class,
// App\Providers\BroadcastServiceProvider::class,
App\Providers\EventServiceProvider::class,
App\Providers\RouteServiceProvider::class,
App\Providers\TenancyServiceProvider::class, // <-- here

Setup Tenant Model

namespace App;

use Stancl\Tenancy\Database\Models\Tenant as BaseTenant;
use Stancl\Tenancy\Contracts\TenantWithDatabase;
use Stancl\Tenancy\Database\Concerns\HasDatabase;
use Stancl\Tenancy\Database\Concerns\HasDomains;

class Tenant extends BaseTenant implements TenantWithDatabase
{
    use HasDatabase, HasDomains;
}

Then, configure the package to use this model in config/tenancy.php:

'tenant_model' => \App\Tenant::class,

Create Migrations For tenant

Create one migration and move that migration file to migrations/tenant. So when we are going to create new tenant this migarations files will run for that new tenant.

You can do the same for seeders. if you want to change the seeder file then you can change it from the config/tenancy.php

Create Actual Tenant

$tenant = Tenant::create([
    'id' => time(),
]);

Result

Now when we run above code it will create new tenant and also create new database with related prefix and given id value.

So it will create following things :

• New Tenant will be created in main database
• New tenant database will be created
• New migrations and seeders will be executed into new tenant database.

Hope that will helps a lot.

In this tutorial, we are going to see how we can implement the authorized hosted payment gateway by using their UI and components and take payments from users via authorized net using Laravel.

Create HTML form as like below code :

authorize.blade.php

{{ Form::open(array('url' => 'https://test.authorize.net/payment/payment')) }}

Form::hidden('token', '{{$token}}');

Form::submit('Click Me!');

{{ Form::close() }}

You must have to pass $token to form, we will see below how we can generate that token.

AuthorizeController.php

 public function onboard() {

    $token = $this->getAnAcceptPaymentPage();

    return view('authorize', compact('token'));
 }

 public function getAnAcceptPaymentPage()
 {
    $merchantAuthentication = new AnetAPI\MerchantAuthenticationType();
    $merchantAuthentication->setName(config('payments.authorize.login_id'));
    $merchantAuthentication->setTransactionKey(config('payments.authorize.transaction_key'));

    $refId = 'ref' . time();

    $transactionRequestType = new AnetAPI\TransactionRequestType();
    $transactionRequestType->setTransactionType("authCaptureTransaction");
    $transactionRequestType->setAmount("2050"); 

    $setting1 = new AnetAPI\SettingType();
    $setting1->setSettingName("hostedPaymentButtonOptions");
    $setting1->setSettingValue("{\"text\": \"Pay\"}");

    $setting2 = new AnetAPI\SettingType();
    $setting2->setSettingName("hostedPaymentOrderOptions");
    $setting2->setSettingValue("{\"show\": false}");

    $setting3 = new AnetAPI\SettingType();
    $setting3->setSettingName("hostedPaymentReturnOptions");
    $setting3->setSettingValue(
        "{\"url\": \"http://127.0.0.1:8000/authorize-success?refID\".$refID, \"cancelUrl\": \"http://127.0.0.1:8000/authorize-cancel\", \"showReceipt\": true}"
    );

    // Build transaction request
    $request = new AnetAPI\GetHostedPaymentPageRequest();
    $request->setMerchantAuthentication($merchantAuthentication);
    $request->setRefId($refId);
    $request->setTransactionRequest($transactionRequestType);

    $request->addToHostedPaymentSettings($setting1);
    $request->addToHostedPaymentSettings($setting2);
    $request->addToHostedPaymentSettings($setting3);

    $controller = new AnetController\GetHostedPaymentPageController($request);
    $response = $controller->executeWithApiResponse(\net\authorize\api\constants\ANetEnvironment::SANDBOX);

    if (($response != null) && ($response->getMessages()->getResultCode() == "Ok")) {

    } else {
        echo "ERROR :  Failed to get hosted payment page token\n";
        $errorMessages = $response->getMessages()->getMessage();
        echo "RESPONSE : " . $errorMessages[0]->getCode() . "  " .$errorMessages[0]->getText() . "\n";
    }
    return $response->getToken();

}

Now create routes into web.php as specified below.

web.php

Route::get('authorize-onboard', [\App\Http\Controllers\AuthorizePaymentController::class, 'onboard'])->name('authorize.init');

Route::get('authorize-success', [\App\Http\Controllers\AuthorizePaymentController::class, 'success']);

How it's going to work ?? (flow)

So initially we will call the route that contains that authorization form and also contains the payment information.

Here we are generating token before, generally, it should be generated from the payment screen.

The token will contains the payment information so while generating it make sure you are passing all the details properly.

Now when you submit the form it will redirect you to the authorized checkout page from where users can do payments and again redirect to the success screen.

Once Payment is done successfully you will be redirected to the success route URL with the RefID which is basically the transaction ID, and you can perform related actions on success action.

Hope it will help.
