记录下有关magento关于面包屑的笔记：

magento的后台有很多类似button标签的按钮，比如：在项目中，我们会对这些面包屑添加一些增删改查的一些功能，这也是面包屑的主要功能之一，但是当有时候项目的一些模块也不需要这些面包屑，那么如何去掉它呢？1.如何去掉右上方的面包屑(Add New):

//在block/Adminhtml/XXX.php中的构造方法中添加一行代码即可class YourModule_Custom_Block_Adminhtml_Custom extends Mage_Adminhtml_Block_Widget_Grid_Container{  public function __construct()  {    $this->_controller = 'adminhtml_custom';    $this->_blockGroup = 'custom';    $this->_headerText = Mage::helper('custom')->__('Custom Manager');    parent::__construct();    //$this->_addButtonLabel = Mage::helper('custom')->__('Add Item');    //删除Add new,添加如下代码：    $this->_removeButton('add');  }}

删除后的效果如图：

2.如何更改面包屑的名称(重命名面包屑)：

//在上述构造方法中取消对这行的注释即可：$this->_addButtonLabel = Mage::helper('custom')->__('Add Item');

3.Magento后台Grid点进去后的Edit页面，也包含了Back、Save和Delete按钮，如何来去除这些按钮呢？

首先,来看下未操作之前的展示图：删除之后的展示图：如何做的？来看下下面的这段代码：

//Block/Adminhtml/Count/Edit.php 页面class Message_Count_Block_Adminhtml_Count_Edit extends Mage_Adminhtml_Block_Widget_Form_Container{    public function __construct()    {        parent::__construct();          $this->_objectId = 'id';        $this->_blockGroup = 'count';        $this->_controller = 'adminhtml_count';        //删除delete按钮        $this->_removeButton('delete');        //删除save按钮        $this->_removeButton('save');        //删除back按钮        $this->_removeButton('back');        //删除reset按钮        $this->_removeButton('reset');        //更改save按钮的名称        $this->_updateButton('save', 'label', Mage::helper('count')->__('Save Item'));        //更改delete按钮的名称        $this->_updateButton('delete', 'label', Mage::helper('count')->__('Delete Item'));        //添加面包屑Save And Continue Edit          $this->_addButton('saveandcontinue', array(            'label'     => Mage::helper('adminhtml')->__('Save And Continue Edit'),            'onclick'   => 'saveAndContinueEdit()',            'class'     => 'save',        ), -100);        $this->_formScripts[] = "            function toggleEditor() {                if (tinyMCE.getInstanceById('count_content') == null) {                    tinyMCE.execCommand('mceAddControl', false, 'count_content');                } else {                    tinyMCE.execCommand('mceRemoveControl', false, 'count_content');                }            }            function saveAndContinueEdit(){                editForm.submit($('edit_form').action+'back/edit/');            }        ";    }
