Laravel 5.8: 你能帮我解决这个关于会话的问题吗
Laravel 5.8: Can you help me with this problem about sessions
我有一个用 Laravel 5.8 编写的在线商店项目,在这个项目中,我在控制器上设置了一些会话,如下所示:
$delivery_types = [];
$conflicting = false;
if ($foundOrder != null) {
foreach ($foundOrder as $key => $value) {
$product = Product::with('uploaded')->wherePrdId($value->id)->select('*')->first();
array_push($delivery_types, $product->prd_delivery);
$prds[] = [
$product,
$value->quantity,
$value->price
];
}
$delivery_types = array_unique($delivery_types);
if (in_array('iran_free_delivery', $delivery_types) && in_array('tehran_free_delivery', $delivery_types)) {
$conflicting = true;
}
if (in_array(null, $delivery_types)) {
Session::put('free' , 'no');
} else if (in_array('iran_free_delivery', $delivery_types) && in_array('tehran_free_delivery', $delivery_types)) {
Session::put('free' , 'city_country');
//Session::put('iran' , '10');
//Session::put('free_notfree' , '13');
} else if (in_array('iran_free_delivery', $delivery_types)) {
Session::put('free' , 'country');
} else if (in_array('tehran_free_delivery', $delivery_types)) {
Session::put('free' , 'city');
} else {
Session::put('free' , '0');
}
} else {
$prds = [];
}
...
return view('frontend.shop.carts.index', compact('conflicting','...')'
问题是,每当 conflicting
重新提交时
checkout.blade.php
,之前添加的那些会话仍然会被提交。
但是,它不应提交旧会话。
那么如何用 Laravel 做到这一点?
非常感谢你的任何想法或建议..
谢谢
像这样尝试一次后,您必须取消设置会话变量
$this->session->unset_userdata('name');
对于多个数据,您可以:
$array_name = array('username' => '', 'email' => '');
$this->session->unset_userdata($array_name);
