laravel ajax pass multiple variables to controller? - ajax

Question

I need to pass 4 variables to controller so that I can do what I want to do with it, however I get an error:
Missing argument 1 for
App\Http\Controllers\ProfileController::getGoogle()
Here's my Controller:
function getGoogle($lat, $lng, $destinationLat, $destinationLng) {
print_r($lat);
print_r($lng);
print_r($destinationLat);
print_r($destinationLng);
}
and ajax:
function getDirections(lat, lng, destinationLat, destinationLng) {
$.ajax({
url: '/google/',
type: 'post',
data: {
lat: lat,
lng: lng,
destinationLat: destinationLat,
destinationLng: destinationLng
},
dataType: 'json',
success: function() { alert('hello!'); },
error: function() { alert('boo!'); },
headers: {
'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
}
});
}
Route:
Route::post('google/', 'ProfileController#getGoogle');

Answer 1

You are actually sending POST variables to the controller, but you are accepting them in controller as GET variables,if you want to read the variables, your controller should be like this:
function getGoogle(Request $request) {
print_r($request->input('lat'));
print_r($request->input('lng'));
print_r($request->input('destinationLat'));
print_r($request->input('destinationLng'));
}
Remember to import Request as use Illuminate\Http\Request;

Answer 2

You aren't passing any parameter via the url and is passing via ajax POST params so you need to change your controller method definition to
function getGoogle() {
print_r(Input::get('lat'));
print_r(Input::get('lng'));
print_r(Input::get('destinationLat'));
print_r(Input::get('destinationLng'));
}
