ErrorException strtotime() 期望参数 1 是字符串，给定数组

Question

谁能帮帮我？这是我的控制器，当我尝试存储“购买”数据时，它显示此消息 strtotime() 期望参数 1 是字符串，给定数组 错误出现在$purchase->date = date('Y-m-d', strtotime($request->date)); 和$purchaseDetail->date = date('Y-m-d', strtotime($request->date));

public function store(Request $request){
    if($request->category_id == null){
        return redirect()->back()->with('error', 'Please Purchase The Product');
    } else{
        // Multipale Data Insert start //
        $purchase = new purchase();
        $purchase->purchase_no = $request->purchase_no;
        $purchase->date        = date('Y-m-d', strtotime($request->date));
        $purchase->description = $request->description;
        $purchase->status      = '0';
        $purchase->created_by  = Auth::user()->id;
        DB::transaction(function() use($request,$purchase) {
           if($purchase->save()) {
            // Purchase Details Insert Start //
            $category_id = count($request->category_id);
            for ($i=0; $i < $category_id; $i++) { 
                $purchaseDetail = new purchaseDetail();
                $purchaseDetail->date               = date('Y-m-d', strtotime($request->date));
                $purchaseDetail->purchase_id        = $purchase->id;
                $purchaseDetail->supplier_id        = $request->supplier_id[$i];
                $purchaseDetail->category_id        = $request->category_id[$i];
                $purchaseDetail->product_id         = $request->product_id[$i];
                $purchaseDetail->buying_qty         = $request->buying_qty[$i];
                $purchaseDetail->unit_price         = $request->unit_price[$i];
                $purchaseDetail->buying_price       = $request->buying_price[$i];
                $purchaseDetail->discount_amount    = $request->discount_amount[$i];
                $purchaseDetail->ppn                = $request->ppn[$i];
                $purchaseDetail->status              = '0';
                $purchaseDetail->save();
            }
        }
        });
    }
    // Redirect 
    return redirect()->route('purchase.view')->with('success', 'Purchase Added Successfully');
}

您好，我尝试将$purchase->date = date('Y-m-d', strtotime($request->date)); 更改为$purchase->date = $request->date; 但结果是 TypeError 传递给 Illuminate\Database\Grammar::parameterize() 的参数 1 必须是数组类型，给定字符串，在 D:\Project Laravel\alc-pos\vendor\laravel\framework\src\Illuminate\Database\Query\ 中调用第 869 行的 Grammars\Grammar.php

至于我的意见，您在保存到数据库时不能格式化您的日期。 相反，您可以在将其从数据库输出到刀片模板时对其进行格式化。

随便查一下$request->date，好像是个数组。

您可以像这样在模型中使用 Laravel 访问器来格式化您的日期（示例）：

    public function getFormattedStartDateAttribute()
    {
        return $this->start_date->format('d-m-Y');
    }

然后像这样在刀片模板中调用它（示例）：

 <input type="text" name="start_date" class="form-control" value="{{$trip->formatted_start_date}}">

你也可以做另一件事。在您的schema::create 上制作：

$table->date('date_name_column');

然后像下面这样保存它：

        $purchaseDetail->date = $request->input('date');

这样数据库中的日期将保存为：YYYY-MM-DD

希望对你有帮助！
