Blade Template - Laravel Blade Template

Blade is a simple templating engine that helps you to create reusable templates for your Laravel application. It is a preprocessor that compiles your templates into PHP code, which is then executed by the server. In this article, we'll explore the Blade template engine in Laravel.

Syntax

The Blade syntax uses double curly braces ({{ }}) to print variables and values, and the @ symbol to indicate control structures, such as loops and conditionals.

Printing Variables

{{ $variable }}

Control Structures

@if (condition)
    // code here
@endif

@foreach ($items as $item)
    // code here
@endforeach

@forelse ($items as $item)
    // code here
@empty
    // code if items array is empty
@endforelse

@switch($type)
    @case(1)
        // code if type is 1
        @break
    @case(2)
        // code if type is 2
        @break
    @default
        // code if type is something else
@endswitch

Blade Layouts

// app.blade.php
<html>
    <head>
        <title>@yield('title')</title>
    </head>
    <body>
        @yield('content')
    </body>
</html>

// home.blade.php
@extends('layouts.app')

@section('title', 'Home')

@section('content')
    <h1>Welcome to the Home Page</h1>
@endsection

Example

Let's say we have a variable $name and we want to print it in a Blade template.

<!-- welcome.blade.php -->
<!DOCTYPE html>
<html>
    <head>
        <title>Welcome</title>
    </head>
    <body>
        <h1>Hello, {{ $name }}!</h1>
    </body>
</html>

Output

The rendered output of this Blade template would look like this:

<!DOCTYPE html>
<html>
    <head>
        <title>Welcome</title>
    </head>
    <body>
        <h1>Hello, John!</h1>
    </body>
</html>

Assuming $name is set to 'John'.

Explanation

In the example above, we used the Blade syntax {{ $name }} to print the value of the $name variable. When the Blade template is compiled, it will be replaced with the PHP code <?php echo $name; ?> which will then be executed by the server and output the value of $name.

Use

Blade templates are used to create reusable templates for your Laravel application. This makes it easier to maintain your application's design and structure, as well as reducing the amount of duplicate code you need to write.
