["menu_0"]=>
array(4) {
["user_order_id"]=>
string(3) " 86"
["menu_id"]=>
string(3) "231"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(1) "3"
}
}
["menu_1"]=>
array(4) {
["user_order_id"]=>
string(3) " 86"
["menu_id"]=>
string(3) "236"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
["menu_2"]=>
array(4) {
["user_order_id"]=>
string(3) " 86"
["menu_id"]=>
string(3) "232"

i want if i used another $oder_id it will show only the session by the $order_id, example my first order_id is 86, it will showed as the first session on top,
than if i used new $order_id example 83, it will show :
["items_250"]=>
array(4) {
["menu_0"]=>
array(4) {
["user_order_id"]=>
string(2) "83"
["menu_id"]=>
string(3) "236"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
["menu_1"]=>
array(4) {
["user_order_id"]=>
string(2) "83"
["menu_id"]=>
string(3) "357"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
but if i used another $order_id
it will be showed this :
["items_250"]=>
array(4) {
["menu_0"]=>
array(4) {
["user_order_id"]=>
string(2) "83"
["menu_id"]=>
string(3) "236"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
["menu_1"]=>
array(4) {
["user_order_id"]=>
string(2) "83"
["menu_id"]=>
string(3) "357"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
["menu_2"]=>
array(4) {
["user_order_id"]=>
string(3) " 86"
["menu_id"]=>
string(3) "232"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
["menu_3"]=>
array(4) {
["user_order_id"]=>
string(3) " 86"
["menu_id"]=>
string(3) "357"
["qty"]=>
string(1) "1"
["choice"]=>
array(1) {
[0]=>
string(0) ""
}
}
}
as you can see from new session, the session of user_order_id are different, but it still showed the last session of user_order_id
this is how i set my session:
if($order_id !== $this->session->userdata('user_order_id')) {
$count = count($menu_id); // get count
for ($i = 0; $i < $count; $i++) {
$_SESSION['items_' . $restaurant_id]['menu_' . $i] = array(
'user_order_id' => $order_id,
'menu_id' => $menu_id[$i],
'qty' => $qty[$i],
"choice" => array($variant_name[$i]['variant_menu_id']),
);
}
}else{
}
guys can you help me how to update the session?
