Introduction:
Laravel Blade is a powerful templating engine that simplifies the process of creating dynamic views in Laravel applications. In this tutorial, we’ll cover a wide range of Blade features, from the basics to more advanced techniques, empowering you to leverage Blade effectively in your projects.
Getting Started with Blade Templates:
Blade templates in Laravel are stored in the resources/views directory. You can create a new Blade file with the .blade.php extension to start using it. Let’s create a simple Blade template called welcome.blade.php :
<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
</head>
<body>
<h1>Hello, {{ $name }}!</h1>
</body>
</html>
Basic Blade Directives:
Blade provides several directives to help you work with templates more efficiently. Some of the basic directives include:
-
{{ $variable }}: Echoing variables. -
@if,@elseif,@else,@endif: Conditional statements. -
@foreach,@endforeach: Looping through arrays. -
@for,@endfor: Looping with a specified number of iterations.
Blade Layouts and Extending:
Blade allows you to create reusable layouts and extend them in other views. Let’s create a layout file called layout.blade.php:
<!DOCTYPE html>
<html>
<head>
<title>@yield('title')</title>
</head>
<body>
<div class="container">
@yield('content')
</div>
</body>
</html>
You can extend this layout in other views using the @extends directive:
@extends('layout')
@section('title', 'Home Page')
@section('content')
<h1>Welcome to our website!</h1>
@endsection
Blade Components and Slots:
Blade components allow you to create reusable UI components. Define a component using the @component directive and render it using the @slot directive:
@component('alert')
@slot('type', 'success')
@slot('message')
This is a success message.
@endslot
@endcomponent
Using Blade Components:
Use Blade components in your views:
@extends('layouts.app')
@section('content')
<x-alert type="success">
This is a success message.
</x-alert>
@endsection
Processing Dynamic Data in Blade Components:
Pass dynamic data to Blade components using the @props directive:
// create a component with dynamic props pre-defined like title, desc
@props(['title','desc'])
<div class="card">
<div class="card-header">
{{ $title }}
{{ $desc}}
</div>
<div class="card-body">
{{ $slot }}
</div>
</div>
// pass the dynamic data using props in you blade file while using the component.
<x-card :title="your-title-here" :desc="your-description-here"/>Rendering JSON Data:
You can render JSON data directly in Blade templates using the json_encode function:
@php
$data = ['John', 'Doe', 'Jane', 'Smith'];
@endphp
<script>
var jsonData = {!! json_encode($data) !!};
console.log(jsonData);
</script>
