如何解决：传递给 Illuminate\Database\Grammar::parameterize() 的参数 1 必须是数组类型，给定字符串

Question

我想存储date，但出现问题。

输入

    <div class="col-lg-6">
       <div class="form-group">
          <label>Date</label>
          <input type="date" name="date" id="date" class="form-control form-control-sm">
       </div> 
    </div>


Controller
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        = $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');
    }

当我存储它时，出现如下错误：

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 中调用 Laravel\alc-pos\vendor\laravel\framework\src\Illuminate\Database\Query\Grammars\Grammar.php 在第 869 行

我尝试改变这个$purchase->date = $request->date;

在这个$purchase->date = date('Y-m-d', strtotime($request->date)); 中出现类似ErrorException strtotime() expects parameter 1 to be string, array given 的错误：

strtotime() 期望参数 1 是字符串，给定数组

Answer 1

似乎$request->date 是一个数组。通过echo print_r($request->date, true); 确认$request->date 确实是一个数组，如果是，您可以看到它的结构。从那里拿走。

目前还没有那么多事情要做。

编辑：

最终解决方案（由@JulienBaldy 在评论部分提供）： 改变

$purchase->date = $request->date;

进入

$purchase->date = date('Y-m-d', strtotime( $request->date[0]));
