Access query string values from Laravel - php

Question

Does anyone know if it's possible to make use of URL query's within Laravel.
Example
I have the following route:
Route::get('/text', 'TextController#index');
And the text on that page is based on the following url query:
http://example.com/text?color={COLOR}
How would I approach this within Laravel?

Answer 1

For future visitors, I use the approach below for > 5.0. It utilizes Laravel's Request class and can help keep the business logic out of your routes and controller.
Example URL
admin.website.com/get-grid-value?object=Foo&value=Bar
Routes.php
Route::get('get-grid-value', 'YourController#getGridValue');
YourController.php
/**
* $request is an array of data
*/
public function getGridValue(Request $request)
{
// returns "Foo"
$object = $request->query('object');
// returns "Bar"
$value = $request->query('value');
// returns array of entire input query...can now use $query['value'], etc. to access data
$query = $request->all();
// Or to keep business logic out of controller, I use like:
$n = new MyClass($request->all());
$n->doSomething();
$n->etc();
}
For more on retrieving inputs from the request object, read the docs.

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
)

Answer 3

Query params are used like this:
use Illuminate\Http\Request;
class ColorController extends BaseController{
public function index(Request $request){
$color = $request->query('color');
}

Answer 4

public function fetchQuery(Request $request){
$object = $request->query('object');
$value = $request->query('value');
}
