Laravel 錯誤異常。 數組到字符串的轉換

[英]Laravel Error Exception. Array to string Conversion

 原文  2022-09-15 11:45:43  8   2    javascript/ php/ jquery/ ajax/ laravel

問題描述

我試圖通過單擊插入多行數據，但出現了一個名為“數組到字符串轉換”的錯誤。 並且當我從 Model 中刪除 Brackets[] 時，如下所示：

受保護的 $table = 'biniyojan';

它會引發另一個像這樣的錯誤：（Illuminate\Database\Grammar::parameterize(): Argument #1 ($values) must be of type array, string given）我該如何解決這個問題？

請試試這個：-

public function bbcreate(Request $request){

    $biniyojan_details = new BiniyojanDetails();
    $biniyojan_details->school = $request->school;
    $biniyojan_details->source = $request->source;
    $biniyojan_details->kriyakalap = $request->kriyakalap;
    $biniyojan_details->debit_credit = $request->debit_credit;
    $biniyojan_details->debit_credit_type = $request->debit_credit_type;
    $biniyojan_details->cash = $request->cash;

    $biniyojan_details->save();

    if(!empty($request->school)){
        for($i=0; $i< count($request->school); $i++){
            $biniyojan              = new Biniyojan();
            $biniyojan->details_id  = $biniyojan_details->id;
            $biniyojan->date        = $request->date[$i];
            $biniyojan->ab          = $request->ab[$i];
            $biniyojan->school      = $request->school[$i];
            $biniyojan->behora      = $request->behora[$i];
            $biniyojan->save();

        }

    }
    return redirect()->back()->with('status', 'Inserted');
}

正如您所說，您正在嘗試insert multiple row data 。

然后您必須將array轉換為json以將其存儲到數據庫中。

這樣做 - json_encode($request->school,true);
