如何使用三元运算符编写此 if..else 条件语句：

Question

我想用三元运算符编写这个 if..else 语句：

if((($request->city)=="98")&&($cartPrice >= 300000)&&($request->province)=="8")){
    "ort_free_delivery" => 'City sending free delivery'
}elseif((($request->city)!="98")&&($cartPrice >=300000)&&($request->province)!="8")){
    "ort_free_delivery" => 'Country sending free delivery'
}else{
    "ort_free_delivery" => '',
}

这是我的尝试：

( ( ($request->city)=="98" ) ? ($cartPrice>=300000) ? ( ( ($request->province)=="8" ) ? "ort_free_delivery" == "City sending free delivery" ) ); 

( ( ($request->city)!="98" ) ? ($cartPrice>=300000) ? ( ( ($request->province)!="8" ) ? "ort_free_delivery" == "Country sending free delivery" : "ort_free_delivery" == "" ) );

但这是错误的，因为有两行三元运算符，而我需要一行中的这个条件（因为我在 Laravel 中插入了一些带有 DB class 的数据）：

    DB::table('order_detail')->insert([
        "ort_ord_id" => $orderId,
        "ort_amount" => $value->price,
        "ort_total" => $value->discounted * $value->quantity,
        "ort_discount" => ($value->price * $value->quantity) - $value->discounted * $value->quantity,
        "ort_type" => "product",
        "ort_number" => $value->quantity,
        "ort_reference_id" => $value->id,
        ( ( ($request->city)=="98" ) ? ($cartPrice>=300000) ? ( ( ($request->province)=="8" ) ? "ort_free_delivery" == "City sending free delivery" ) )
        ( ( ($request->city)!="98" ) ? ($cartPrice>=300000) ? ( ( ($request->province)!="8" ) ? "ort_free_delivery" == "Country sending free delivery" : "ort_free_delivery" == "" ) )
        "created_at" => now(),
        "updated_at" => now()
    ]);

所以我的问题是如何在一行中添加带有三元运算符的条件语句？

更新 #1:

我试过这个来检查条件是否有效：

if ($foundOrder != null) {
                DB::table('order_detail')->whereOrtOrdId($orderId)->delete();
                foreach ($foundOrder as $key => $value) {
                    $existProduct = DB::table('order_detail')->whereOrtOrdId($orderId)->whereOrtReferenceId($value->id)->exists();
                    if (empty($existProduct)) {
                        $price = Product::wherePrdId($value->id)->select('prd_sale_price')->first();
                        if($request->city==98&&$cartPrice >= 300000&&$request->province==8){
                            dd('city');
                        }elseif($request->city!=98&&$cartPrice >=300000&&$request->province!=8){
                            dd('country');
                        }else{
                            $data["ort_free_delivery"] = '';
                        }
                    }
                }
            } else {
                DB::table('order_detail')->whereOrtOrdId($orderId)->delete();
            }

它正确显示 city 和 country 如果它们的条件 return 为真，

一个选项是

$data=[
        "ort_ord_id" => $orderId,
        "ort_amount" => $value->price,
        "ort_total" => $value->discounted * $value->quantity,
        "ort_discount" => ($value->price * $value->quantity) - $value->discounted * $value->quantity,
        "ort_type" => "product",
        "ort_number" => $value->quantity,
        "ort_reference_id" => $value->id,
        "created_at" => now(),
        "updated_at" => now()
    ];  
    
if($request->city==98&&$cartPrice >= 300000&&$request->province==8){
    $data["ort_free_delivery"] = 'City sending free delivery';
}elseif($request->city!=98&&$cartPrice >=300000&&$request->province!=8){
     $data["ort_free_delivery"] = 'Country sending free delivery';
}else{
    $data["ort_free_delivery"] = '';
}

然后查询

  DB::table('order_detail')->insert($data);

或

DB::table('order_detail')->insert([
    "ort_ord_id" => $orderId,
    "ort_amount" => $value->price,
    "ort_total" => $value->discounted * $value->quantity,
    "ort_discount" => ($value->price * $value->quantity) - $value->discounted * $value->quantity,
    "ort_type" => "product",
    "ort_number" => $value->quantity,
    "ort_reference_id" => $value->id,
    "ort_free_delivery" =>($request->city==98&&$cartPrice >= 300000&&$request->province==8)?'City sending free delivery':
        (($request->city!=98&&$cartPrice >=300000&&$request->province!=8)?'Country sending free delivery':null),
    "created_at" => now(),
    "updated_at" => now()
]);
