Php 从laravel中传递的数组对象更新DB:：table

在laravel中，我试图更新几个表和行。我有两个不同的用户要接收和检查的项目

在show.blade.php中，根据用户的不同，我有这个verify按钮和submit按钮

@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

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

对于所有选择要更新的行。当您转储简单值时，您得到了什么？当我在输入中输入一个单词时，例如：hello，表中唯一保存的是字母h。once$items=json_decode（$request->items）；在保存到数据库之前返回响应，看看您得到了什么新的，当我有3行被更新时，它不再工作了。我收到这个错误：QueryException in Connection.php第636行：SQLSTATE[42000]：语法错误或访问冲突：1064您的SQL语法有错误；检查与您的MariaDB服务器版本相对应的手册，了解第1行“where

purchase\u items

id

is null”附近使用的正确语法（SQL:update

items

Internal join

purchase\u items

on

items

purchase\u items

itemsset

items

度量+其中

purchase\u items

id

为空）
