我正在关注这个包装器

我有这样的错误:开捕致命错误:传递给XeroPHP \型号\会计\发票:: setDueDate(参数1)必须实现接口DateTimeInterface,字符串中给定

这是我的代码:

try{
            $lineitem = new LineItem($this->_xi);
            $lineitem->setAccountCode('200')
            ->setQuantity('5.400')
            ->setDescription('this is awesome test')
            ->setUnitAmount('9900.00');

            $contact = new Contact($this->_xi);
            $contact->setName("John Doe")
                ->setFirstName("John")
                ->setLastName("Doe")
                ->setEmailAddress("johngwapo@hot.com")
                ->setContactStatus(Contact::CONTACT_STATUS_ACTIVE);



            $invoice = new Invoice($this->_xi);
            $invoice->setType(Invoice::INVOICE_TYPE_ACCREC)
                ->setStatus(Invoice::INVOICE_STATUS_AUTHORISED)
                ->setContact($contact)
                //->setDate(\DateTimeInterface::format("Y-m-d"))
                ->setDueDate("2018-09-09")
                ->setLineAmountType(Invoice::LINEAMOUNT_TYPE_EXCLUSIVE)
                ->addLineItem($lineitem)
                ->setInvoiceNumber('10')
                ->save();



        }catch ( Exception $e ){
            $GLOBALS['log']->fatal('[Xero-createContact]-' . $e->getMessage());
            echo $e->getMessage();

        }

当我尝试这样做时:

->setDueDate(\DateTimeInterface::format("Y-m-d"))

我得到了这个错误:致命错误:非静态方法DateTimeInterface :: format()无法静态调用,假设$ this来自不兼容的上下文

这是我调用的setDueDate的功能:

 /**
     * @param \DateTimeInterface $value
     * @return Invoice
     */
public function setDueDate(\DateTimeInterface $value)
    {
        $this->propertyUpdated('DueDate', $value);
        $this->_data['DueDate'] = $value; …

我很困惑,因为如果我删除te .toFixed(2)然后条件将返回false,因此是正确的,但如果有.toFixed(2)它返回true,这是错误的.

此外,当我使用console.log显示包含值的两个变量时,它们都返回此值

5.00 and 20.00

这是代码:

//this two values are actually populated from .val of an input field
var coupon_limit2 = 0;
var coupon_limit = $("#product_coupon_limit").val();
var sale_price = $("#product_product_list_price").val();


if(disc_type == "Percentage"){
            if(coupon_type == "amount"){
                coupon_limit2 = (coupon_limit/sale_price)*100;
            }else{
                coupon_limit2 = coupon_limit;
            }
        }else{
            if(coupon_type == "percent"){
                coupon_limit2 = (coupon_limit/100)*sale_price;
            }else{
                coupon_limit2 = coupon_limit;
            }
        }

var x = parseFloat($("#product_product_discount").val()).toFixed(2);
var y = coupon_limit2;

//returns correctly
if(x > parseFloat(y)){
   alert("hi"); 
}

//returns wrong
if(x > parseFloat(y).toFixed(2)){
   alert("hi"); 
} …
