[英]How to store array cookie in laravel 5.4?
I have this function in laravel 5.4 but I get error. 我在laravel 5.4中有这个功能,但是我得到了错误。
$cart[$product->id] = $quantity;
var_dump($cart);
return redirect('catalogs')->withCookie(cookie()->forever('cart', $cart));
var_dump($cart) contains this: var_dump($ cart)包含:
array(1) { [1]=> string(1) "1" }
Error warning: 错误警告:
Method Symfony\Component\HttpFoundation\Cookie::__toString() must not throw an exception, caught ErrorException: Array to string conversion
If I passed just string value (not array), it success. 如果我只传递字符串值(不是数组),那就成功了。 If there any way to store array cookie in Laravel?
如果有任何方法可以在Laravel中存储数组cookie?
Thank you. 谢谢。
Only strings can be stored in a cookie. 只有字符串可以存储在cookie中。 So try this:
试试这个:
$cart[$product->id] = $quantity;
var_dump($cart);
return redirect('catalogs')->withCookie(cookie()->forever('cart', serialize($cart)));
Warning: Do not use serialize/unserialize http://php.net/manual/en/function.unserialize.php#refsect1-function.unserialize-notes 警告:不要使用序列化/反序列化http://php.net/manual/en/function.unserialize.php#refsect1-function.unserialize-notes
You can store it as JSON 您可以将其存储为JSON
$user=['name'=>'Imran','email'=>'xyz*emphasized text@gmail.com'];
$array_json=json_encode($user);
return redirect('user')->withCookie(cookie()->forever( 'user',$array_json, 450000));
On retrieval 在检索
$user=\Cookie::get('user');
$user=json_decode($user);
echo $user->name;
echo $user->email;
