How do I redirect to a URL with query parameters?

Question

I am trying to do a redirect with query parameters, using the redirect() helper:

$link = 'https://example.com' . '?key1=value1&key2=value2';

return redirect()->to($link);

The problem is that when the $link is passed to the to() method Laravel removes the question mark leading the query string, so it turns this:

https://example.com?key1=value1&key2=value2

into this:

https://example.comkey1=value1&key2=value2

(again, notice the missing ? in the final link).

How do I make a redirect with query params appended to a custom URL?

Answer 1

Use:

return redirect($link);

If you want to redirect a named route with query string, use:

return redirect()->route('route_name',['key'=> $value]);

Answer 2

The approved answer explains it all, according to the documentation. However, if you are still interested in finding some kind of "hard-coded" alternative:

$link = "https://example.com?key1={$value1}&key2={$value2}";

Then,

return redirect($link);

Reference

If the link is to a page on your domain, you don't need to re-write the domain name, just:

$link = "?key1=${value1}&key2=${value2}";

Laravel will automatically prepend the URL with your APP_URL (.env)

Answer 3

If you're building a Single Page Application (SPA) and you want to redirect to a specific page within your app from a server request, you can use the query method from the Arr helper class. Here is an example:

$result = Arr::query([
    'result' => 'success',
    'code' => '200'
]);

return redirect("/purchase?$result");

This will redirect the user to the /purchase page with the query parameters result=success and code=200.

For example, the final url would be:

http://example.com/purchase?result=success&code=200

Answer 4

Get the value of the query param:

request()->query('param')

Redirect to a named route including query parameter:

redirect(route('name', ['foo' => request()->query('param')]));
