如何在購物車價格規則內添加自定義選項卡

Question

我試圖在magento促銷/購物車價格規則中添加自定義選項卡。我需要的是，當我選擇任何規則時，自定義選項卡顯示在「管理優惠券代碼」下方，當我點擊自定義選項卡時，我必須獲取具有保存並保存並繼續編輯按鈕的網格表格。任何人都可以建議我以正確的方式來做到這一點？

這就是我要添加新的自定義選項卡下面的「管理優惠券代碼」窗口：

對於完整的解釋，你可以參考這個http://www.newgenray.com/2015/04/22/creating-custom-tab-on-edit-page-in-an-existing-module-of-magento/

首先，你需要創建一個模塊，你必須定義兩件事情之一是佈局和塊

<config> 
<modules> 
    <Newgenray_Coupon> 
     <version>0.0.1</version> 
    </Newgenray_Coupon> 
</modules> 
<adminhtml> 
    <layout> 
     <updates> 
      <newgenray_coupon> 
       <file>coupon.xml</file> 
      </newgenray_coupon> 
     </updates> 
    </layout> 
</adminhtml> 
<global> 
    <blocks> 
     <newgenray_coupon> 
      <class>Newgenray_Coupon_Block</class> 
     </newgenray_coupon> 
    </blocks> 
</global> 

然後在文件app /代碼/本地/ Newgenray /座/ Adminhtml /促銷/報價/編輯/標籤/ Custom.php

class Newgenray_Coupon_Block_Adminhtml_Promo_Quote_Edit_Tab_Custom extends Mage_Adminhtml_Block_Widget_Form 
implements Mage_Adminhtml_Block_Widget_Tab_Interface 
{ 
/*public function __construct(){ 
    $this->setTemplate('newgenray_coupon/custom_tab.phtml'); 
}*/ 

/** 
* Mandatory to override as we are implementing Widget Tab interface 
* Return Tab Title 
* 
* @return string 
*/ 
public function getTabTitle(){ 
    return Mage::helper('salesrule')->__('Custom Tab'); 
} 

/** 
* Mandatory to override as we are implementing Widget Tab interface 
* Return Tab Label 
* 
* @return string 
*/ 
public function getTabLabel(){ 
    return Mage::helper('salesrule')->__('Custom Tab'); 
} 

/** 
* Mandatory to override as we are implementing Widget Tab interface 
* Can show tab in tabs 
* Here you can write condition when the tab should we shown or not. Like you see when we create shopping cart rule 
* Manage coupon tab doesn't come. If you want that then just make a function and check whether you have information 
* in registry or not 
* 
* @return boolean 
*/ 
public function canShowTab(){ 
    return true; 
} 

/** 
* Mandatory to override as we are implementing Widget Tab interface 
* Tab is Hidden 
* 
* @return boolean 
*/ 
public function isHidden(){ 
    return false; 
} 

/** 
* Defines after which tab this tab should come like you asked you need it below Manage Coupon codes 
* 
* @return string 
*/ 
public function getAfter(){ 
    return 'coupons_section'; 
} 

public function _prepareForm(){ 
    /* To set the data in the form you need to get the data in registry In my example 
    * I don't have any registry so I am commenting it. My Form will be blank 
    */ 
    //$model = Mage::registry('custom_tab_form_data'); 

    $form = new Varien_Data_Form(); 

    $form->setHtmlIdPrefix('rule_'); 

    $fieldset = $form->addFieldset('custom_fieldset', array(
     'legend'=>Mage::helper('salesrule')->__('Your Custom Field Set ') 
    )); 

    $fieldset->addField('name', 'text', array(
     'label'  => Mage::helper('salesrule')->__('Name'), 
     'class'  => 'required-entry', 
     'required' => true, 
     'name'  => 'name', 
     'note'  => Mage::helper('salesrule')->__('The name of the example.'), 
    )); 

    $fieldset->addField('description', 'text', array(
     'label'  => Mage::helper('salesrule')->__('Description'), 
     'class'  => 'required-entry', 
     'required' => true, 
     'name'  => 'description', 
    )); 

    $fieldset->addField('other', 'text', array(
     'label'  => Mage::helper('salesrule')->__('Other'), 
     'class'  => 'required-entry', 
     'required' => true, 
     'name'  => 'other', 
    )); 


    //$form->setValues($model->getData()); 
    $this->setForm($form); 

    return parent::_prepareForm(); 
} 
} 

然後在文件app /應用/設計/ adminhtml /默認/缺省/佈局/coupon.xml

<?xml version="1.0"?> 
<layout version="0.1.0"> 
    <adminhtml_promo_quote_edit> 
      <reference name="promo_quote_edit_tabs"> 
       <action method="addTab"> 
        <name>promo_quote_edit_tab_custom</name> 
        <block>newgenray_coupon/adminhtml_promo_quote_edit_tab_custom</block> 
       </action> 
      </reference> 
     </adminhtml_promo_quote_edit> 
    </layout> 

最後一步將被激活，我們剛剛創建

<?xml version="1.0"?> 
<config> 
<modules> 
    <Newgenray_Coupon> 
     <active>true</active> 
     <codePool>local</codePool> 
    </Newgenray_Coupon> 
</modules> 
</config>
