10 Laravel Quick Tips

Tip 1. Controllers Having Single Action

In some situations you need a single action in a controller, if this is the case in Laravel you can achieve it by **__invoke()** method.

<?php

namespace App\Http\Controllers;
use App\User;
use App\Http\Controllers\Controller;

class ShowProfile extends Controller
{
   /**
   * Show the profile for the given user.
   *
   * @param int $id
   * @return Response
   */
    public function __invoke($id)
    {
         return view('user.profile', ['user' => User::findOrFail($id)]);
    }
}

Routes:

Route::get('user/{id}', 'ShowProfile');

Artisan command to generate this controller:

php artisan make:controller ShowProfile --invokable

Tip 2. Migration Fields Having Timezone

Do you know in Laravel migrations are just not limited to **timestamps()** you can also add **timestampsTz()**

Schema::create('employees', function (Blueprint $table) {
 $table->increments('id');
 $table->string('name');
 $table->string('email');
 $table->timestampsTz();
});

Also, there are columns **dateTimeTz()** , **timeTz()** , **timestampTz()**, **softDeletesTz()**.

Tip 3. Eloquent has() deeper

You can use Eloquent has() function to query relationships even two layers deep!

// Author -> hasMany(Book::class);
// Book -> hasMany(Rating::class);
$authors = Author::has('books.ratings')->get();

Tip 4. SoftDeletes: Restore Multiple

To restore soft deleted rows, you can restore them in one sentence.

User::withTrashed()->where('author_id', 1)->restore();

Tip 5. Image Validation

During image upload, validate images on specific dimensions.

'photo' => 'dimensions:max_width=4096,max_height=4096'

Tip 6. Wildcard Subdomains

You can create route group by dynamic subdomain name, and pass its value to every route.

Route::domain('{username}.workspace.com')->group(function () {
 Route::get('user/{id}', function ($username, $id) {
 //
 });
});

Php how to delete multiple rows through checkbox using ajax in laravel

First thing, we will need a table and i am creating products table for this example. So run the following query to create table.

CREATE TABLE `products` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 `description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
 `updated_at` datetime DEFAULT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Next, we will need to insert some dummy records in this table that will be deleted.

INSERT INTO `products` (`name`, `description`) VALUES

('Test product 1', 'Product description example1'),

('Test product 2', 'Product description example2'),

('Test product 3', 'Product description example3'),

('Test product 4', 'Product description example4'),

('Test product 5', 'Product description example5');

Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = [
        'name','description'
    ];
}

Step 2: Create Route

Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.

routes/web.php

Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);
