Laravel Blade is a powerful and easy-to-use templating engine that comes with Laravel, a popular PHP web application framework. Here is a cheat sheet of some common Blade directives and their usage:
Echoing Data:
{{ $variable }} - Outputs the value of a variable
{!! $variable !!} - Outputs the value of a variable, but with HTML encoding disabled |
Control Structures:
@if ($condition)
// code to execute if condition is true
@endif
@unless ($condition)
// code to execute if condition is false
@endunless
@if ($condition)
// code to execute if condition is true
@elseif ($otherCondition)
// code to execute if otherCondition is true
@else
// code to execute if both conditions are false
@endif
@switch($variable)
@case(value)
// code to execute if $variable == value
@break
@case(anotherValue)
// code to execute if $variable == anotherValue
@break
@default
// code to execute if none of the above cases are true
@endswitch |
Loops:
@foreach ($items as $item)
// code to execute for each item in the array
@endforeach
@for ($i = 0; $i < 10; $i++)
// code to execute for each iteration of the loop
@endfor
@while ($condition)
// code to execute as long as the condition is true
@endwhile |
Including Subviews:
@include('subview')
@include('subview', ['key' => 'value']) |
Extending Layouts
@extends('layout')
@section('content')
// content to be included in the 'content' section of the layout
@endsection |
Displaying Blade Syntax Errors:
@error('field_name')
<div class="alert alert-danger">{{ $message }}</div>
@enderror |
Commenting:
{{-- This is a Blade comment and will not be rendered in the HTML output --}} |
Displaying Partials:
@each('partials.item', $items, 'item') |
Displaying Components:
@component('components.alert')
@slot('title')
Alert Title
@endslot
Alert body text goes here.
@endcomponent |
Displaying a View Based on a Condition:
@isset($variable)
@include('view')
@endisset |
