LARAVEL 在數據庫中插入多行

Question

我正在嘗試使用單擊在兩個數據庫表中插入多行數據，但此代碼一次只插入一行。 當我嘗試 dd($request->all()); 我在數組中得到數據，但只插入一行。 有什么問題，我該如何解決？

受保護的 $table = 'biniyojan';

////修改后的控制器//////

public function bbcreate(Request $request)
{

    //dd($request->all());
    $biniyojan_details = new BiniyojanDetails();


    $biniyojan = new Biniyojan();
    $biniyojan->details_id = $biniyojan_details->details_id;
    $biniyojan->date =  $request->date;
    $biniyojan->ab =  $request->ab;
    $biniyojan->school =  $request->school;
    $biniyojan->behora =  $request->behora;
    $biniyojan->save();


    $biniyojan_details = new BiniyojanDetails();
    if (!empty($request->school)) {
        for ($i = 0; $i < count((array)$request->school); $i++) {
        $biniyojan_details['biniyojan_id'] = $biniyojan->id;
        $biniyojan_details['school'] = $request->school[$i];
        $biniyojan_details['source'] = $request->source[$i];
        $biniyojan_details['kriyakalap'] = $request->kriyakalap[$i];
        //$biniyojan_details->debit_credit = $request->debit_credit[$i];
        //$biniyojan_details->debit_credit_type = $request->debit_credit_type[$i];
        $biniyojan_details['cash'] = $request->cash[$i];
        $biniyojan_details->save();
        }
    }
    return redirect()->back()->with('status', 'Inserted');
}

Answer 1

正如@aynber 指出的那樣，您需要移動該行$biniyojan_details = new BiniyojanDetails(); 在循環內部，因此它為每次迭代啟動一個新的 object。

另一種解決方案是同時插入所有條目（更好的性能）。 為此，我們首先准備要插入的數據

public function bbcreate(Request $request)
{

    //dd($request->all());
    $biniyojan_details = new BiniyojanDetails();


    $biniyojan = new Biniyojan();
    $biniyojan->details_id = $biniyojan_details->details_id;
    $biniyojan->date =  $request->date;
    $biniyojan->ab =  $request->ab;
    $biniyojan->school =  $request->school;
    $biniyojan->behora =  $request->behora;
    $biniyojan->save();


    $biniyojanDetailsToBeInserted = [];
    if (!empty($request->school)) {
        for ($i = 0; $i < count((array)$request->school); $i++) {
            $biniyojan_details = [];
            $biniyojan_details['biniyojan_id'] = $biniyojan->id;
            $biniyojan_details['school'] = $request->school[$i];
            $biniyojan_details['source'] = $request->source[$i];
            $biniyojan_details['kriyakalap'] = $request->kriyakalap[$i];
            //$biniyojan_details['debit_credit'] = $request->debit_credit[$i];
            //$biniyojan_details['debit_credit_type'] = $request->debit_credit_type[$i];
            $biniyojan_details['cash'] = $request->cash[$i];
            $biniyojanDetailsToBeInserted[] = $biniyojan_details;
        }
    }
    if ($biniyojanDetailsToBeInserted) {
        BiniyojanDetails::insert($biniyojanDetailsToBeInserted);
    }
    return redirect()->back()->with('status', 'Inserted');
} 

Answer 2

您的代碼僅創建一行，但值得注意的是它創建了一行，但包含數組的最后一個數據。

因為您沒有在循環內制作 object，所以它在循環外，所以循環在同一個 object 上運行，並在每次循環運行時更新其屬性並保存它。

在循環內創建 object ，這樣每次都會創建新的 object ，這意味着每次都會創建新行而不是更新同一行。

如果數組鍵的名稱與數據庫表列的名稱相同，則有更好的方法。

Biniyojan::insert($request->data);

它是這樣工作的。

User::insert([
    ['name' => 'John', 'email' => 'john@example.com'],
    ['name' => 'Marina', 'email' => 'marina@example.com'],
]);
