Laravel How to delete session on the homepage - php

Question

Im using javascript in Homepage to pass variable to next page (Im using controller to store variable in session) , now how can I empty the session if loaded the home page again?
$(document).on('click', '.btn_getbids', function() {
$.ajax({
type: 'post',
url: 'addItem',
data: {
'_token': $('input[country=_token]').val(),
'country': $('input[name=country]').val() },
success: function(data) {
}, });
$('#country').val('');});
Controller
public function addItem(Request $request) {
$request->session()->put('country', $request->country);
return response ()->json ( $data );
}

Answer 1

Assuming you have an IndexController where you call the homepage function to call your home view.
public function homepage(Request $request){
//check if session exists
if($request->session()->has('country'){
//forget session
$request->session()->forget('country');
}
}
With this code, session country will be forgotten every time you go to the homepage.

Have you tried:
public function addItem(Request $request) {
if($request->session()->has('country'){
$request->session()->forget('country'); //if you want to clear specific one
//$request->session()->flush //if you want to flush all
}
$request->session()->put('country', $request->country);
return response ()->json ( $data );
}
