#payment/method_creditlimit ->Mage/Payment/Model/Method/creditlimit.php<br>配置完之后再后台支付哪里可以看到，启用支付插件System > Configuration > Payment Methods

5、修改前端支付方法文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

#app/design/frontend/default/theme592/template/checkout/onepage/payment/methods.phtml   /*处理是否允许用户类型支付*/ if($_code == "creditlimit"){             $Type = $this->getCustomer()->getType();             /*用户是个人，支付只支持公司*/             if(intval($Type) != 1){                 continue;             }             /*如果是企业用户*/             $maxOrderTotalCL= $this->getCustomer()->getCreditThreshold();             $grandTotal = $this->getQuote()->getBaseGrandTotal();             if(intval($maxOrderTotalCL) > $grandTotal){ //如果订单总数小于允许最大值时                 continue;             }             /*获取当前可用信用额度*/             $CreditLimit = (float)$this->getCustomer()->getCreditLimit();  //该用户的信用额度             $useCreditLimit = (float)$this->getCustomer()->getUseCreditLimit();//已经使用了信用额度             $CreditLimitPercent = (float)$this->getCustomer()->getCustomPayment();//已经使用了信用额度             $usedCreditLimit = (float)($CreditLimit-$useCreditLimit);//可用额度             $usedCreditLimit = $usedCreditLimit<0?0:$usedCreditLimit;             $tipceCreditLimit[$_code] = $this->__('当前可用信用额度 <b style="color:#f00;">HK$%s</b>',sprintf('%.2f',$usedCreditLimit));             /*信用额度不足的情况*/             if($grandTotal > $CreditLimit){                 if($CreditLimitPercent==0) $CreditLimitPercent = 50;                 $MethodFormHtml[$_code] = $this->__('因定单金额过大，下单后我们将先收取该订单金额的%s',$CreditLimitPercent."%");             }elseif($usedCreditLimit<$grandTotal){                 $MethodFormHtml[$_code] = $this->__('当前可用信用额度不足，下单后请等待客服人员联系.');             } }

6、后台添加订单状态

System > Order Status

在app/code/core/Mage/order.php文件中的351行下面添加两个状态

const STATE_PENDING_REPAYMENT = 'pending_repayment';
const STATE_PENDING_DEPOSIT = 'pending_deposit';

7、处理订单

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#在code/core/Mage/Checkout/controllers/OnepageController.php文件的successAction方法中添加代码   /*订单*/  $order = Mage::getSingleton('sales/order')->loadByIncrementId($IncrementId);         $paymentMethod = $order->getPayment()->getMethod();         if($paymentMethod == 'creditlimit'){             Mage::dispatchEvent('payment_model_method_creditlimit_pay', array('order' => $order)); } #payment_model_method_creditlimit_pay触发器在code/core/Mage/Checkout/etc/config.xml文件中添加事件 <payment_model_method_creditlimit_pay><!-- 事件的名字 -->        <observers>            <update_creadit_limit><!-- 任何唯一的标示符 -->            <type>singleton</type>           <class>Mage_Payment_Model_Method_Creditlimit</class><!-- 我们自己的类(class) -->            <method>UpdateCustomerCreditLimit</method><!-- 方法名 -->           </update_creadit_limit>         </observers>   </payment_model_method_creditlimit_pay>   #类和方法在code/core/Mage/Payment/Model/Method/Creditlimit.php文件中<br>#/js/mage/adminhtml/tools.js文件中添加了一个方法后台处理订单状态使用<br>#/design/adminhtml/default/default/template/qquoteadv/sales/order/view/info.phtml文件中添加订单状态处理按钮
