Today I would like to share some laravel tips an<\/font>d tricks. Let’s take a look.<\/p>\n\n\n\n

Use Carbon with Only Hours<\/strong><\/h3>\n\n\n\n

If you want to have a current date without seconds and\/or minutes, use Carbon’s methods like setSeconds(0) or setMinutes(0).<\/p>\n\n\n\n

echo now();<\/p>\n\n\n\n

\/\/ 2022-02-14 02:12:34<\/p>\n\n\n\n

echo now()->setSeconds(0);<\/p>\n\n\n\n

\/\/ 2022-02-14 02:12:00<\/p>\n\n\n\n

echo now()->setSeconds(0)->setMinutes(0);<\/p>\n\n\n\n

\/\/ 2022-02-14  02:00:00<\/p>\n\n\n\n

\/\/ Another way – even shorter<\/p>\n\n\n\n

echo now()->startOfHour();<\/p>\n\n\n\n

<\/p>\n\n\n\n

Generate Images with Seeds\/Factories<\/strong><\/h3>\n\n\n\n

Normally, We use Faker to generate fake text values in seeds and factories. But do you know that you can generate not only text values but also Images by Faker?<\/p>\n\n\n\n

For example: See image field here – it will generate 100×100 image:<\/p>\n\n\n\n

$factory->define(User::class, function (Faker $faker) {<\/p>\n\n\n\n

    return [<\/p>\n\n\n\n

        ‘name’ => $faker->name,<\/p>\n\n\n\n

        ‘email’ => $faker->unique()->safeEmail,<\/p>\n\n\n\n

        ‘email_verified_at’ => now(),<\/p>\n\n\n\n

        ‘password’ => bcrypt(‘password’),<\/p>\n\n\n\n

        ‘remember_token’ => Str::random(10),<\/p>\n\n\n\n

        ‘Image’ => $faker->image(storage_path(‘images’), 100, 100)<\/p>\n\n\n\n

    ];<\/p>\n\n\n\n

});<\/p>\n\n\n\n

<\/p>\n\n\n\n

Simple Pagination<\/strong><\/h3>\n\n\n\n

In pagination, if you need just “Previous\/next” links instead of all the page numbers (and have fewer DB queries because of that), You can do this easily by changing paginate() to simplePaginate():<\/p>\n\n\n\n

\/\/ Instead of<\/p>\n\n\n\n

$products = Product::paginate(8);<\/p>\n\n\n\n

\/\/ Now you can do this<\/p>\n\n\n\n

$products = Product::simplePaginate(8);<\/p>\n\n\n\n

<\/p>\n\n\n\n

Use @auth in Blade<\/strong><\/h3>\n\n\n\n

Instead of an if-statement to check logged-in users, You can use the @auth directive in your blade file.<\/p>\n\n\n\n

Old way:<\/p>\n\n\n\n

@if(auth()->user())<\/p>\n\n\n\n

    \/\/ The user is authenticated.<\/p>\n\n\n\n

@endif<\/p>\n\n\n\n

Latest:<\/p>\n\n\n\n

@auth<\/p>\n\n\n\n

    \/\/ The user is authenticated.<\/p>\n\n\n\n

@endauth<\/p>\n\n\n\n

The opposite is @guest directive:<\/p>\n\n\n\n

@guest<\/p>\n\n\n\n

    \/\/ The user is not authenticated.<\/p>\n\n\n\n

@endguest<\/p>\n\n\n\n

<\/p>\n\n\n\n

Check the view file exists<\/strong><\/h3>\n\n\n\n

You can check if the View file exists before actually loading it.<\/p>\n\n\n\n

if (view()->exists(‘admin.dashboard’)) {<\/p>\n\n\n\n

 \/\/ Load the view<\/p>\n\n\n\n

}<\/p>\n\n\n\n

You can even load an array of views, and only the first existing will be loaded.<\/p>\n\n\n\n

return view()->first([‘admin.dashboard’, ‘dashboard’], $data);<\/p>\n\n\n\n

<\/p>\n\n\n\n

Create migration without underscore _ symbol<\/strong><\/h3>\n\n\n\n

When you are running a make:migration command, you don’t necessarily have to write underscore _ symbol between parts, like create_users_table.<\/p>\n\n\n\n

\/\/ with underscore _ symbol<\/p>\n\n\n\n

php artisan make:migration create_users_table<\/p>\n\n\n\n

You can enter the name into quotes and then utilize spaces instead of underscores.<\/p>\n\n\n\n

\/\/ without underscore _ symbol<\/p>\n\n\n\n

php artisan make:migration “create users table”<\/p>\n\n\n\n

<\/p>\n\n\n\n

Use Auth::once()<\/strong><\/h3>\n\n\n\n

Do you know that you c an log in with the user only for One Request? You can easily do this by utilizing the method Auth::once(). No sessions or cookies will be used, which indicates this method may be applicable when building a stateless API.<\/p>\n\n\n\n

if (Auth::once($credentials)) {<\/p>\n\n\n\n

    \/\/<\/p>\n\n\n\n

}<\/p>\n\n\n\n

<\/p>\n\n\n\n

Use @canany to check multiple permissions at once<\/strong><\/h3>\n\n\n\n

Earlier, You use the @can directive to check if a user has a certain permission. Now, you can also check multiple permissions at once with the @canany directive.<\/p>\n\n\n\n

@canany([‘update’, ‘view’, ‘delete’], $blog)<\/p>\n\n\n\n

    \/\/ The current user can update, view, or delete the blog post<\/p>\n\n\n\n

@elsecanany([‘create’], \\App\\Blog::class)<\/p>\n\n\n\n

    \/\/ The current user can create a blog post<\/p>\n\n\n\n

@endcanany<\/p>\n\n\n\n

<\/p>\n\n\n\n

This is all for now. Hope you enjoy that.<\/p>\n\n\n\n
