Append Query String to Route in Laravel

How to Append Query String to Route in Laravel ?

Aman Jain,

In this guide, we’ll explore the methods and best practices on append query string to route in Laravel. One common requirement is appending query strings to routes, a task often encountered when dealing with dynamic data and user interactions.

Understanding Query Strings and Routes in Laravel

Before diving into the techniques, let’s clarify what query strings and routes mean in the context of Laravel. In web development, a query string is a part of a URL that contains data to be passed to a web page. Laravel’s routing system, on the other hand, is responsible for directing incoming requests to the appropriate controller.

Append query string to url in laravel

Appending a query string to a route in Laravel is a straightforward process. The url helper function comes in handy for this task. Consider the following example:

$url = url('article/detail', ['id' => 1, 'type' => 'post']);

or 
$url = url('article/detail', request()->all());

In this case, the resulting URL would be something like http://your-app.com/article/detail?id=1&type=post. The url helper takes the route and an array of parameters, appending them as a query string.

Append query string to Route in laravel using Helper Route function

Appending a query string to a route in Laravel is a straightforward process. The Route helper function comes in handy for this task. Consider the following example:

$url = route('article/detail', ['id' => 1, 'type' => 'post']);

or 
$url = route('article/detail', request()->all());

In this case, the resulting URL would be something like http://your-app.com/article/detail?id=1&type=post. The Route helper takes the route and an array of parameters, appending them as a query string. if you want to append without query params then you can use below code

$url = route('article/detail', $id);

Resultant url will be http://your-app.com/article/detail/1

Redirect with query params in laravel

Laravel provides the Request object, allowing developers to access various aspects of an HTTP request. To append query parameters dynamically based on the current request, you can use the merge method:

use Illuminate\Http\Request;

public function someControllerMethod(Request $request)
{
    $query = $request->query(); // $request->all();
    $query['additional_param'] = 'some_value';

    return redirect()->route('your.route.name')->withQuery($query);
}

This method ensures that existing query parameters are preserved while appending new ones.

Conditional Query String Append to URL

In some scenarios, you might want to conditionally append query strings based on certain criteria. Laravel’s when method provides an elegant solution for this:

use Illuminate\Support\Facades\Route;

Route::get('/conditional-route', function () {
    $parameter = // Some condition;

    return redirect()->route('your.route.name')->when($parameter, function ($query) {
        return $query->merge(['conditional_param' => 'some_value']);
    });
});

I hope this article will help you to create proper url with query params.
