To retrieve the query parameters on your Laravel backend, you can make use of either the "Request" class or the "request()" helper method.
By using the Request Instance
Imagine you want to get the "search" query from the URL, you can do as follows.
By using the Request Instance
Imagine you want to get the "search" query from the URL, you can do as follows.
$searchQuery = $request->query('search');If the requested query string value data is not present, the second argument to this method will be returned.
$name = $request->query('search', 'Learn laravel');You may call the query method without any arguments in order to retrieve all of the query string values as an associative array.
$query = $request->query();
Full Code Example
<?php
namespace App\Http\Controllers;
use App\Models\Post;
use Illuminate\Http\Request;
class SearchPost extends Controller
{
/**
* Handle the incoming request.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\RedirectResponse
*/
public function __invoke(Request $request)
{
$searchQuerey = $request->query('search', 'Learn laravel');
$posts = Post::query()->where('title', 'LIKE', $searchQuerey)->take(10)->get();
return view('posts.index', compact('posts'));
}
}By using request() Helper
Otherwise, if you prefer to use the "request()" helper, then it will be like below.
$searchQuery = request()->query('search');
