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'
