php - 从 laravel 中传递的数组对象更新 DB::table

Question

在 laravel 中，我正在尝试更新多个表和行。我有一些元素要由 2 个不同的用户接收和检查。

在我的 show.blade.php 中，我有这个验证按钮和提交按钮，具体取决于用户。

@if (($current_user_id  != $saved_receiver_id) && ($saved_receiver_id != $not_yet_received))    

    <div class="row padder m-b">
        <div class="col-md-12">
            <label for="received_by" class="pull-left" >Received by:</label> <span class="fa"></span>
            <input type="hidden" name="receiver_id" value="{{ $saved_receiver_id }}" >{{ $receiver_username }}</input>
        </div>
    </div>
    <div class="row padder m-b">
        <div class="col-md-12">
            <label for="received_date" class="pull-left" >Received date:</label> <span class="fa"></span>
            <input type="hidden" name="received_date" value="{{ $received_date }}" >{{ $received_date }}</input>
        </div>
    </div>
    <input type="hidden" name="purchase_orders_id" value="{{ $purchase_order_number }}">
    <input type="hidden" name="checker_id" value="{{ $current_user_id }}">
    <div class="row padder m-b">
        <div class="col-md-12">
            <label for="final_checker_remarks" class="pull-left" >Final Remarks</label>
            <textarea class="form-control col-md-12" name="final_checker_remarks" value="{{ $final_checker_remarks }}" id="final_checker_remarks">{{ $final_checker_remarks }}</textarea>
        </div>
    </div>
    <br />
    <div class="row">
        <div class="col-md-12">
            <button type="button" class="pull-right btn btn-success btn-sm submit-btn" id="update-form-submit" data-action="verified">Verified</button>
        </div>
    </div>
    @else
    <div class="pull-right">
        <div class="btn-group">
            <button type="button" class="btn btn-info btn-sm submit-btn" id="update-form-submit" data-action="submit">Submit List</button>
        </a>
    </div>
@endif

现在在我的 ReceivesController.php 中，我有这个 postUpdate 函数，

public function postUpdate(Request $request)
{
    if (! $request->ajax()) {
        abort(404);
    }

    $items = json_decode($request->items);
    $action = json_decode($request->action);        
    if(!count($items) && !count($items->purchase_item_id)){
        return false;
    }

    $cnt = count($items->purchase_item_id);     
// Receiver Submit function 
    if ($action == "submit") {

// Saves the received id of the one who received to purchase order table        
        DB::table('purchase_orders')
        ->where('id', $items->purchase_orders_id)
        ->update([
            'receiver_id'       =>  $items->receiver_id,

        ]);


// Saves the quantity received and receiver remarks to purchase items table 
        for($i=0; $i<$cnt; $i++){
            DB::table('purchase_items')
            ->where('id', $items->purchase_item_id[$i])
            ->update([
                    'quantity_received' =>  $items->quantity_received[$i], 
                    'receiver_remarks'  =>  $items->receiver_remarks[$i],
                ]);
        }   
// Items Received Success Message           
        $message = 'Items Received';
    } 
// QA or Checker Finalize function  
    else {

// Saves the checker id, and final checker remarks of the one who made the QA to purchase order table   
        DB::table('purchase_orders')
        ->where('id', $items->purchase_orders_id)
        ->update([
            'checker_id'            =>  $items->checker_id,
            'final_checker_remarks' =>  $items->final_checker_remarks,
        ]);
// Saves the quality received and checker remarks to purchase items table   
for($i=0; $i<$cnt; $i++){                       

            $quality_received = $items->quality_received;
            if(is_array($items->quality_received)){
                $quality_received = $items->quality_received[$i];
            }

            $checker_remarks = $items->checker_remarks;
            if(is_array($items->checker_remarks)){
                $checker_remarks = $items->checker_remarks[$i];
            }

            $quantity_received = $items->quantity_received;
            if(is_array($items->quantity_received)){
                $quantity_received = $items->quantity_received[$i];
            }

            $receiver_remarks = $items->receiver_remarks;
            if(is_array($items->receiver_remarks)){
                $receiver_remarks = $items->receiver_remarks[$i];
            }


            DB::table('purchase_items')
            ->where('id', $items->purchase_item_id[$i])
            ->update([
                    'quality_received'  =>  $quality_received, 
                    'checker_remarks'   =>  $checker_remarks,                       
                    'quantity_received' =>  $quantity_received, 
                    'receiver_remarks'  =>  $receiver_remarks,
                ]);
// Increments or Adds the quantity received to items table  
            DB::table('items')
            ->where('purchase_items.id', $items->purchase_item_id[$i])
            ->join('purchase_items', 'items.id', '=', 'purchase_items.item_id')
            ->increment('items.measurement', $items->quantity_received[$i]);

        }
/   / Items Finalized Success Message       
        $message = 'Items Verified';
    }
// Returns Success Message 
    return response()->json([
            'success' => true,
            'message' => $message
        ]);
}

现在我的问题是只有在输入区域中输入的单词的第一个字母被保存，而在其他区域则不保存，但是在其他区域可以保存。我知道这很奇怪，但我找不到我的代码的哪一部分正在做这样的结果，我需要做什么才能正确更新我的表？先谢谢您的帮助。

更新:这是我的 receive-form-function.js

Answer 1

我上面的 $.fn.serializeObject = function() 似乎有错误，我尝试使用另一个 $.fn.serializeObject = function()，它给了我我想要的 json 对象。这是我现在使用的 $.fn.serializeObject = function() 。

$.fn.serializeObject = function()
{
    var o = {};
    var a = this.serializeArray();
    $.each(a, function() {
        if (o[this.name] !== undefined) {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }
            o[this.name].push(this.value || '');
        } else {
            o[this.name] = this.value || '';
        }
    });
    return o;
};
