我的 Controller :

function generateallmonthreport()
    {
        $month = $this->input->post('month');
        $year = $this->input->post('year');
        $familyid = $this->session->userdata('family_id');

        $fulldata['dates'] = $this->Itemreport_model->getreportallmonth($month,$year);
        $fulldata['members1'] = $this->Itemreport_model->getindependentmembers($familyid);
        $fulldata['members2'] = $this->Itemreport_model->getindependentmembers($familyid);
        $fulldata['members3'] = $this->Itemreport_model->getindependentmembers($familyid);
        $fulldata['members4'] = $this->Itemreport_model->getindependentmembers($familyid);
        $fulldata['members5'] = $this->Itemreport_model->getindependentmembers($familyid);
        $fulldata['year'] = $year;
        $fulldata['month'] = $month;

        $this->load->view('header');
        $this->load->view('itemreports/allmonthreportpage', $fulldata);
        $this->load->view('footer');
    }

我的模型:

function getreportallmonth($month,$year)
{
    $sql = "SELECT DISTINCT `item_date` FROM `items` WHERE MONTH(`item_date`)='$month' AND YEAR(`item_date`)='$year'";
    $query = $this->db->query($sql);
    return $query->result();
}

function getindependentmembers($familyid)
{
    $sql = "SELECT * FROM `familymember` WHERE `family_id`='$familyid' AND `dependency`='1'";
    $query = $this->db->query($sql);
    return $query->result();
}

function getcountofexpensetype($memberid,$year,$month)
{
    $sql = "SELECT COUNT(DISTINCT `item_expensetype`) AS spancount FROM `items` WHERE `item_purchaseby`='$memberid' AND MONTH(`item_date`)='$month' AND YEAR(`item_date`)='$year' AND `item_expensetype` IS NOT NULL";
    $query = $this->db->query($sql);
    return $query->result();
}

function getexpensetype($memberidforexpensetype,$year,$month)
{
    $sql = "SELECT DISTINCT `item_expensetype` as expensetype FROM `items` WHERE `item_purchaseby`='$memberidforexpensetype' AND MONTH(`item_date`)='$month' AND YEAR(`item_date`)='$year' AND `item_expensetype` IS NOT NULL";
    $query = $this->db->query($sql);
    return $query->result();
}

function getallitems($thisdate)
{
    $sql = "SELECT `item_name`,`item_price`,`item_purchasetype` FROM `items` WHERE `item_date`='$thisdate'";
    $query = $this->db->query($sql);
    return $query->result();
}

function getexpensetypefinal($memberidforexpensetypeprice,$year,$month)
{
    $sql = "SELECT DISTINCT `item_expensetype` as expensetype FROM `items` WHERE `item_purchaseby`='$memberidforexpensetypeprice' AND MONTH(`item_date`)='$month' AND YEAR(`item_date`)='$year' AND `item_expensetype` IS NOT NULL";
    $query = $this->db->query($sql);
    return $query->result();
}

我的看法:

<table border="2" id="tab" style="width:100%" class="text-center m-auto table table-bordered table-hover">

                    <tr>

                                    $countforcolspan = $this->Itemreport_model->getcountofexpensetype($memberid,$year,$month);
                                ?>

代码似乎工作正常但给了我尝试获取非对象属性的通知

错误:

A PHP Error was encountered Severity: Notice Message: Trying to get property of non-object Filename: itemreports/allmonthreportpage.php Line Number: 68

Backtrace: File: D:\wampserver\www\home\application\views\itemreports\allmonthreportpage.php Line: 68 Function: _error_handler

File: D:\wampserver\www\home\application\controllers\Itemreport.php Line: 91 Function: view

File: D:\wampserver\www\home\index.php Line: 315 Function: require_once

我无法发现代码的不当部分..请帮助..!!
