Laravel route url with query string

Laravel's route() and action() helper methods support URL query params. The url() helper method, unfortunately does not.

Simply provide an array with key => value pairs to the route parameters. For example:

route('products.index', ['manufacturer' => 'Samsung']);

// Returns 'http://localhost/products?manufacturer=Samsung'

You can also still include your route parameters (such as ID's and models) to accompany these parameters:

route('products.show', [$product->id, 'model' => 'T9X']);

// Returns 'http://localhost/products/1?model=T9X'

Basically, any elements in the array that contain string keys will be treated as query parameter (/products?param=value). Anything with an integer array key will be treated as a URL argument (/products/{arg}).

This is also supported in action methods:

action('ProductController@index', ['manufacturer' => 'Samsung']);

You can also supply query parameters inside the link_to_route() and link_to_action() methods:

link_to_route('products.index', 'Products by Samsung', ['model' => 'Samsung');

link_to_action('ProductController@index', 'Products by Samsung', ['model' => 'Samsung']);

2019 - EDIT:

If you can't use route() or action(), you can generate a URL with query params using the Arr::query() helper:

url('/products?').\Illuminate\Support\Arr::query(['manufacturer' => 'Samsung']);

// Returns 'http://localhost/products?manufacturer=Samsung'

Or:

url('/products?').http_build_query(['manufacturer' => 'Samsung'], null, '&', PHP_QUERY_RFC3986);

// Returns 'http://localhost/products?manufacturer=Samsung'

Or create a simple helper function:

use Illuminate\Support\Arr;
use Illuminate\Support\Str;

function url_query($to, array $params = [], array $additional = []) {
    return Str::finish(url($to, $additional), '?') . Arr::query($params);
}

Then call it:

url_query('products', ['manufacturer' => 'Samsung']);

// Returns 'http://localhost/products?manufacturer=Samsung'

url_query('products', ['manufacturer' => 'Samsung'], [$product->id]);

// Returns 'http://localhost/products/1?manufacturer=Samsung'

The following was what I needed to do:

I handle all of my routing in a service provider, where I had defined the following function:

private function registerRestfulController($prefix, $controllerClass)
{
    Route::controller($prefix, $controllerClass, $controllerClass::getRouteNames());
}

getRouteNames is a static method on my BaseController that conventionally returns routes so that RESTful controllers can have automatic named routes.

The problem I was running into was that this defined the set of wildcard matchers on the route itself - in order to avoid that, I add the following to the private function above:

foreach ($controllerClass::getRoutesNames() as $name) { 
    $route = Route::getRoutes()->getByName($name);
    $cleanUri = preg_replace('/\/\{\w*\?\}/', '', $route->getUri());
    $route->setUri($cleanUri);
}

This loads all the routes you are registering at the time and immediately removes wildcards from the URI. You could easily pass a boolean or "white-list" of route names that you want to preserve wildcards for, so that it doesn't stomp all over the Laravel default without the intention. Once you run this, it automatically starts working with query string variables, which I find far preferable to path variables in this instance.

A simple way to do this, specially to use with jQuery Autocomplete, it's modify the Controller with a condition to check if has 'term' in the $request:

(Controller file)

public function list_for_autocomplete(Request $request)
{
    if ($request->has('term')) {
        return YourModel::select('column_name as value')
            ->where('column_name', 'like', '%' . $request->input('term') . '%')
            ->get()
    }
}

$query = implode([
    route('your_route_name'),
    '?',
    http_build_query(['param1'=>'def','param2'=>'def'])
]);

Vanilla php resolve that without worries
