Blade Control Structures - @if, @foreach, @forelse
Blade provides clean directives for PHP control structures. @if/@elseif/@else for conditionals, @foreach for loops, @forelse for loops with empty state handling, @for, @while, and the special $loop variable that tracks iteration state.
Control Structures
@if($user->isAdmin())
<span class="badge">Admin</span>
@elseif($user->isEditor())
<span class="badge">Editor</span>
@else
<span class="badge">Member</span>
@endif
{{-- @unless is the opposite of @if --}}
@unless(Auth::check())
<a href="/login">Please log in</a>
@endunless
{{-- @forelse - loop with empty fallback --}}
@forelse($posts as $post)
<article>
<h2>{{ $post->title }}</h2>
</article>
@empty
<p>No posts found.</p>
@endforelse
{{-- The $loop variable --}}
@foreach($users as $user)
{{ $loop->index }} {{-- 0-based index --}}
{{ $loop->iteration }} {{-- 1-based index --}}
{{ $loop->first }} {{-- true on first item --}}
{{ $loop->last }} {{-- true on last item --}}
{{ $loop->count }} {{-- total items --}}
@endforeachIndustry Best Practices
- Always write tests for this functionality - it's the most reliable way to catch regressions when you refactor or update packages
- Document your implementation decisions in code comments, especially when you deviate from Laravel conventions - future team members (including yourself) will thank you
- Follow the single responsibility principle: each class does one thing. If a method grows beyond 20 lines, consider extracting helper methods or moving logic to a service class
- Profile performance with Laravel Debugbar (composer require barryvdh/laravel-debugbar) during development - it shows query counts, memory usage, and timeline for every request
- Keep dependencies up to date: run composer audit regularly to check for security vulnerabilities in your package dependencies

Tip
Tip
Practice Blade Control Structures if foreach forelse in small, isolated examples before integrating into larger projects. Breaking concepts into small experiments builds genuine understanding faster than reading alone.
Blade compiles to plain PHP - zero overhead in production
Practice Task
Note
Practice Task - (1) Write a working example of Blade Control Structures if foreach forelse from scratch without looking at notes. (2) Modify it to handle an edge case (empty input, null value, or error state). (3) Share your solution in the Priygop community for feedback.
Quick Quiz
Common Mistake
Warning
A common mistake with Blade Control Structures if foreach forelse is skipping edge case testing - empty inputs, null values, and unexpected data types. Always validate boundary conditions to write robust, production-ready laravel code.
