Access Query String Values from Laravel

Laravel get query string

To determine if an input value is present:

if ($request->has('invitee')) {
   $user->invitee = $request->input('invitee');
}

The has method returns true if the value is present and is not an empty string:

Access query string values from Laravel

Yes, it is possible. Try this:

Route::get('test', function(){
    return "<h1>" . Input::get("color") . "</h1>";
});

and call it by going to http://example.com/test?color=red.

You can, of course, extend it with additional arguments to your heart's content. Try this:

Route::get('test', function(){
    return "<pre>" . print_r(Input::all(), true) . "</pre>";
});

and add some more arguments:

http://example.com/?color=red&time=now&greeting=bonjour`

This will give you

Array
(
    [color] => red
    [time] => now
    [greeting] => bonjour
)

how to access query string in controller and routes of laravel

The query string is considered part of the inputs and not part of the URI for routing. If you want the 'id' part of the URI to be optional you would have to adjust your definition. Then in your controller you can access your reference query string parameter.

Route::get('user/{id?}', 'UserController@index')->name('user');

public function index(Request $request, $id = null)
{
    $reference = $request->input('reference');
    ...
}

Get query string:

$query is the query string.

How can I access query string parameters for requests I've manually dispatched in Laravel 4?

You are correct in that using Input is actually referencing the current request and not your newly created request. Your input will be available on the request instance itself that you instantiate with Request::create().

If you were using (as you should be) Illuminate\Http\Request to instantiate your request then you can use $request->input('key') or $request->query('key') to get parameters from the query string.

Now, the problem here is that you might not have your Illuminate\Http\Request instance available to you in the route. A solution here (so that you can continue using the Input facade) is to physically replace the input on the current request, then switch it back.

// Store the original input of the request and then replace the input with your request instances input.
$originalInput = Request::input();

Request::replace($request->input());

// Dispatch your request instance with the router.
$response = Route::dispatch($request);

// Replace the input again with the original request input.
Request::replace($originalInput);

This should work (in theory) and you should still be able to use your original request input before and after your internal API request is made.

getting query parameters from URL in laravel 7.1

In Route::post you don't need set the parameters in route. Just use:

Route::post("your-route", "YourControllerController@doSomeThing");

So, in app/Http/Controllers/YourControllerController.php file:

class YourControllerController extends Controller {

public function doSomeThing(Request $request)
{
    echo $request->input('param1');
    echo $request->input('param2');
    echo $request->input('param3');
}

To get request paramters either its POST or GET use the request() helper for it.

Example:
URL: http://travel.localhost/home?name=google

Use request()->get('name'); Result will be google this can be used for post parameters as well.

If you want to get all the request paramters
Use request()->all() Result will be

[
   'name' => 'google'
]

Also check your app\Http\Kernel.php file and see if you're missing any middleware mentioned in below picture.
