我有类似的购物车。在我的项目中，用户和访客可以将产品添加到购物车。用户还可以。当来宾用户在购物车中添加产品时，我将其保存为带有会话ID的数据库。还可以。但是，当来宾用户关闭站点时，我无法从db中删除记录。我如何检测被破坏的会话？
我有一个GuestUserProvider，它在db中创建新的来宾用户
$session_id = session()->get( '_token' );
$guests = GuestUser::all();
foreach ($guests as $guest){
}
if(!empty($guest)){
if($session_id != $guest['session_id']){
$created = GuestUser::create([
'session_id' => $session_id,
'ip' => $clientIP = \Request::ip()
]);
}
}else{
$created = GuestUser::create([
'session_id' => $session_id,
'ip' => $clientIP = \Request::ip()
]);
}
并添加到购物车功能
public function gocart(Request $request)
{
$session_id = session()->get( '_token' );
if(Auth::User()){
$ifs = Cart::where(['product_id' => $request['id'], 'user_id' =>
Auth::user()->id])->get();
}else{
$ifs = Cart::where(['product_id' => $request['id'], 'session_id'
=> $session_id])->get();
}
if(count($ifs) > 0) {
foreach ($ifs as $if) {}
$count = $if['quantity'];
$newCount = $count + 1;
if(count($ifs) >= 1){
Cart::where('product_id', $request['id'])->update([
'quantity' => "$newCount"
]);
}
}else{
$products = ProductNew::where('id', $request['id'])->get();
$images = Pimage::select('image')->where('product_id',
$request['id'])->first();
$image = $images['image'];
foreach ($products as $product) {
$main = ProductNew::where('group', $product['group'])-
>first();
$title = $main['title'];
$price = $product['price'];
$quantity = 1;
if(Auth::user()){
Cart::create([
'user_id' => Auth::user()->id,
'product_id' => $request['id'],
'session_id' => $session_id,
'quantity' => $quantity,
'title' => $title,
'price' => $price,
'image' => $product['image'],
'option' => $product['option'],
'ip' => $clientIP = \Request::ip()
]);
}else{
Cart::create([
'user_id' => '0',
'product_id' => $request['id'],
'session_id' => $session_id,
'quantity' => $quantity,
'title' => $title,
'price' => $price,
'image' => $product['image'],
'option' => $product['option'],
'ip' => $clientIP = \Request::ip()
]);
}
}
}
toastr()->error('Data has been saved successfully!');
return back();
