如何使用三元運算符編寫這些“if..else”條件語句

Question

我想用三元運算符編寫這些if..else語句：

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" => '',
}

這是我的嘗試：

( ( ($request->city)=="98" ) ? ($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" == "" ) ); 

但這是錯誤的，因為有兩行三元運算符，我需要在一行中包含這個條件（因為我在 Laravel 中插入了一些帶有 DB 類的數據）：

    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()
    ]);

所以我的問題是，如何在一行中添加帶有三元運算符的條件語句？

Answer 1

你可以試試這個。 這個想法是用第二個三元替換第一個:之后的語句。 僅當第一個條件為假時才會評估第二個三元組。

    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" : "" ) ),
        "created_at" => now(),
        "updated_at" => now()
    ]);

Answer 2

一種選擇是構建數組然后插入

$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()
    ];  

對於條件數據

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"] = '';
}

然后查詢

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

或者

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()
]);

Answer 3

使用var_dump進行測試，而不是你所擁有的，這就是我想出的：

(((($request->city=="98")&&($cartPrice>=300000)&&($request->province=="8"))?var_dump('1'):((($request->city!="98")&&($cartPrice>=300000)&&($request->province=="8"))?var_dump('2'):var_dump('3'))))

以更易讀的方式：

(
    (
        (
            ($request->city == "98") && 
            ($cartPrice >= 300000) && 
            ($request->province == "8")
        )
        ? var_dump('1') 
        : (
            (
                ($request->city != "98") && 
                ($cartPrice >= 300000) && 
                ($request->province == "8") 
            )
            ? var_dump('2')
            : var_dump('3')
          )
    )
)

Answer 4

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

人工讀取代碼：

如果cartPrice 低於300000 總是''

否則如果兩個城市都是 98 並且省同時是 8 (AND) ...

是“城市發送..”

別的

是“國家發送..”

因為：

主要區分規則似乎 city=98 和 Province=8 都必須為 True 才能成為“城市發送”......

......所以所有其他情況都是“國家發送”......

... 當購物車價格 >= 300000
