The if blade directive

• @if()
• @elseif()
• @else
• @endif

The @ symbol may also be used to escape Blade directives:

  {{-- Blade template --}}@@if()  <!-- HTML output -->@if()

You may construct if statements using the @if, @elseif, @else, and @endif directives. These directives function identically to their PHP counterparts:

@if (count($records) === 1)    I have one record!@elseif (count($records) > 1)    I have multiple records!@else    I don't have any records!@endif

The foreach blade directive

• @foreach()
• @endforech

While iterating through a foreach loop, a $loop variable will be available inside of your loop. This variable provides access to some useful bits of information such as the current loop index and whether this is the first or last iteration through the loop:

@foreach ($users as $user)   @if ($loop->first)     This is the first iteration.   @endif   @if ($loop->last)    This is the last iteration.   @endif   <p>This is user {{ $user->id }}</p>@endforeach

The csrf blade directive

• The @csrf directive is used in the form.
• It is also used in Laravel applications to verify tokens.

Anytime you define an HTML form in your application, you should include a hidden CSRF token field in the form so that the CSRF protection middleware can validate the request. You may use the @csrf Blade directive to generate the token field:

<form method=”POST” action=”/profile”>  @csrf…</form>

The unless blade directive

For convenience, Blade also provides an @unless directive:

@unless (Auth::check())You are not signed in.@endunless

The isset and empty blade directives

In addition to the conditional directives already discussed, the @isset and @empty directives may be used as convenient shortcuts for their respective PHP functions:

@isset($records)// $records is defined and is not null…@endisset@empty($records)// $records is “empty”…@endempty

The production blade directive

You may check if the application is running in the production environment using the @production directive:

@production// Production specific content…@endproduction

Or, you may determine if the application is running in a specific environment using the @env directive:

@env('staging')// The application is running in "staging"...@endenv@env(['staging', 'production'])// The application is running in "staging" or "production"...@endenv

The verbatim directive

If you are displaying JavaScript variables in a large portion of your template, you may wrap the HTML in the @verbatim directive so that you do not have to prefix each Blade echo statement with an @ symbol:

@verbatim<div class="container">Hello, {{ name }}.</div>@endverbatim

The hasSection blade directive

@hasSection('navigation')
    
@endif

The code above checks if a section inherited has content.

The sectionMissing blade directive

@sectionMissing('navigation')
    
@endif

The above code checks if the section’s contents are missing.

The switch blade directive

@switch($i)
    @case(1)
        First case...
        @break
    @default
       
@endswitch

Just like your normal switch statement, the @switch() blade directive functions the same.

The for loop blade directive

@for ($i = 0; $i < 10; $i++)
    The current value is {{ $i }}
@endfor

The blade directives are just simple and short forms that Laravel uses to simplify some PHP functions to make your codes simple and readable.
