The @if directive allows conditional rendering in templates, making it possible to dynamically control whether content is displayed. This is very useful for building flexible dynamic pages.
@if($user->isAdmin)
This user is an admin.
@endif
In the example above, if the $user object's isAdmin property is true, the template will display “This user is an admin.” Otherwise, this content will not be shown.
The @foreach directive allows you to iterate over arrays or collections within a template, making it easy to process and render each element.
@foreach($users as $user)
{{ $user->name }}
@endforeach
In this example, $users is a collection containing multiple user objects. The loop accesses and outputs the name of each user one by one.
The @include directive is used to include another template file inside the current template, enabling modularization and code reuse.
@include('partials.header')
Here, @include pulls in the partials.header template fragment, allowing reuse of the page header content and keeping code clean.
@yield defines placeholders in a parent template, which child templates can fill with specific content, enabling template content extension.
<!DOCTYPE html>
<html>
<head>
<title>@yield('title')</title>
</head>
<body>
@yield('content')
</body>
</html>
The example defines two placeholders, 'title' and 'content'. Child templates extend the parent template and fill these sections with actual content.
The @extends directive specifies which parent template the current template inherits from. Used alongside @section and @endsection, it defines which content the child template injects into the parent.
@extends('layouts.app')
<p>@section('content')<br>
<p>This is the content of the page.</p><br>
@endsection<br>
In this example, the child template extends the layouts.app parent template and fills the 'content' section with specific content, achieving page structure reuse and extension.
In summary, these five Blade directives significantly enhance the flexibility and efficiency of Laravel template development. Mastering them helps developers better organize code, optimize template structure, and build clearer, more maintainable Laravel applications.
