Implementing Real-Time Search with Livewire in Laravel
Adding real-time search functionality to your Laravel application can greatly enhance the user experience by allowing users to see search results instantly as they type. In this tutorial, we'll walk through how to build a live search feature using Livewire in Laravel.
Prerequisites
- Basic understanding of Laravel and Livewire
- A Laravel project with Livewire installed
Objective
We'll create a real-time search form that filters and displays results as the user types in the search input field.
Step 1: Setting Up the Livewire Component
First, let's create a Livewire component to handle our search functionality.
Component Class
Run the following command to generate a Livewire component:
php artisan make:livewire SearchPosts
Open the newly created SearchPosts.php
file and set up the properties and methods to manage the search query and results:
<?php
namespace App\Http\Livewire;
use Livewire\Component;
use App\Models\Post;
class SearchPosts extends Component
{
public $query = '';
public $posts = [];
public function updatedQuery()
{
$this->posts = Post::where('title', 'like', '%' . $this->query . '%')->get();
}
public function render()
{
return view('livewire.search-posts');
}
}
Step 2: Creating the Blade View
Next, create the Blade view for this component in resources/views/livewire/search-posts.blade.php
.
Blade Template
<div>
<!-- Search Input -->
<input type="text" placeholder="Search posts..." wire:model="query" class="border rounded p-2 w-full">
<!-- Search Results -->
@if(!empty($posts))
<ul class="mt-4">
@foreach($posts as $post)
<li class="p-2 border-b">{{ $post->title }}</li>
@endforeach
</ul>
@elseif(strlen($query) > 0)
<p class="mt-4 text-gray-500">No results found for "{{ $query }}".</p>
@endif
</div>
Step 3: Updating the Routes
Ensure your Livewire component is properly routed. Add the following to your web.php
file:
use App\Http\Livewire\SearchPosts;
Route::get('/search-posts', SearchPosts::class);
Step 4: Testing the Search Functionality
Navigate to http://your-app-url/search-posts
in your browser. Start typing in the search input field, and you should see the search results update in real-time.
Explanation
- Search Query Binding: The
query
property is bound to the search input field. As the user types, theupdatedQuery
method is triggered.
- Dynamic Search: The
updatedQuery
method performs a search on thePost
model using alike
query and updates theposts
property with the results. The results are then rendered dynamically in the view.
- Livewire Reactivity: Livewire automatically handles the reactivity, updating the search results as the
query
property changes without the need for a full page reload.
Conclusion
With Livewire, adding real-time search functionality to your Laravel application is straightforward and efficient. This tutorial showed how to create a live search feature, providing instant feedback to users as they type, enhancing the overall user experience.
