本文详细介绍如何在Magento后台定制Grid控件，包括配置步骤、关键代码解析及实现功能的具体方法。

对于在后台的grid，form等控件，在显示的时候前，一般在_prepareForm（这个比较复杂，后面再介绍！）

在RichardMason_Profile_Block_Adminhtml_Profile_Grid定义的

protected function _prepareColumns()

{

$baseUrl = $this->getUrl();

$this->addColumn('content_heading', array(

'header' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'),'content_heading'),

'align' => 'left',

'index' => 'content_heading'

));

if(Mage::registry('profile_category_id') != RichardMason_Profile_Model_Profile::CATEGORY_RELEASES) {

$this->addColumn('content', array(

'header' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'),'content'),

'align' => 'left',

'index' => 'content'

));

}

if (!Mage::app()->isSingleStoreMode()) {

$this->addColumn('store_id', array(

'header' => Mage::helper('profile')->__('Store View'),

'index' => 'store_id',

'type' => 'store',

'store_all' => true,

'store_view' => true,

'sortable' => false,

'filter_condition_callback'

=> array($this, '_filterStoreCondition'),

));

}

$this->addColumn('is_active', array(

'header' => Mage::helper('profile')->__('Status'),

'index' => 'is_active',

'type' => 'options',

'options' => array(

0 => Mage::helper('profile')->__('Disabled'),

1 => Mage::helper('profile')->__('Enabled')

));

$this->addColumn('creation_time', array(

'header' => Mage::helper('profile')->__('Date Created'),

'index' => 'creation_time',

'type' => 'datetime',

));

$this->addColumn('update_time', array(

'header' => Mage::helper('profile')->__('Last Modified'),

'index' => 'update_time',

'type' => 'datetime',

));

return parent::_prepareColumns();

}

$this->addColumns('store_id',array())

在这个函数里面的这个方法为Mage_Adminhtml_Block_Widget_Grid的方法，这里覆盖

目的是为了设置

访问url

profile/adminhtml_profile/news/key/fdsfsdfsadfds

grid的流程显示：

前提，各种资源，model，config.xml都配置好，

1.config.xml配置。

<menu>

<cms>

<sort_order>60</sort_order>

<action>profile/adminhtml_profile/news</action>

</news>

</children>

2 controller----newsaction方法的填写

在RichardMason_Profile_Adminhtml_ProfileController写一个函数newsAction（）

public function newsAction(){

Mage::register('profile_category_id', RichardMason_Profile_Model_Profile::CATEGORY_NEWS);

$this->_initAction()

->renderLayout();

}

protected function _initAction() {

$this->loadLayout()

->_setActiveMenu('profile/items')

->_addBreadcrumb(Mage::helper('adminhtml')->__('Profiles Manager'), Mage::helper('adminhtml')->__('Profile Manager'));

return $this;

}

3.layouthandle

到profile.xml中写一个layouthandle：

<profile_adminhtml_profile_news>

</reference>

</profile_adminhtml_profile_news>

4.Block/Adminhtml/Profile.php

RichardMason_Profile_Block_Adminhtml_Profile extends Mage_Adminhtml_Block_Widget_Grid_Container

public function __construct()

{

$this->_controller = 'adminhtml_profile';

$this->_blockGroup = 'profile';

$this->_headerText = Mage::helper('profile')->getText(Mage::registry('profile_category_id'), '_headerText');

parent::__construct();

parent::_addButton('add', array(

'label' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'), 'New'),

'onclick' => 'setLocation(/''.$this->getUrl('*/*/edit', array('category_id' => Mage::registry('profile_category_id'))).'/')',

'class' => 'add',

));

}

因为在该函数构造的时候需要用到grid，系统的默认路径为adminhtml/profile/grid.php(prifile.php的地址：adminhtml)

class RichardMason_Profile_Block_Adminhtml_Profile_Grid extends Mage_Adminhtml_Block_Widget_Grid

{

//1

public function __construct()

{

parent::__construct();

$this->setId('profileBlockGrid');

$this->setDefaultSort('profile_id');

$this->setDefaultDir('ASC');

}

//2

protected function _prepareCollection()

{

$collection = Mage::getModel('profile/profile')->getCollection();

$collection->addFieldToFilter('category_id', Mage::registry('profile_category_id'));

/* @var $collection Mage_Cms_Model_Mysql4_Block_Collection */

$this->setCollection($collection);

return parent::_prepareCollection();

}

//3

protected function _prepareColumns()

{

$baseUrl = $this->getUrl();

$this->addColumn('content_heading', array(

'header' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'),'content_heading'),

'align' => 'left',

'index' => 'content_heading'

));

if(Mage::registry('profile_category_id') != RichardMason_Profile_Model_Profile::CATEGORY_RELEASES) {

$this->addColumn('content', array(

'header' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'),'content'),

'align' => 'left',

'index' => 'content'

));

}

if (!Mage::app()->isSingleStoreMode()) {

$this->addColumn('store_id', array(

'header' => Mage::helper('profile')->__('Store View'),

'index' => 'store_id',

'type' => 'store',

'store_all' => true,

'store_view' => true,

'sortable' => false,

'filter_condition_callback'

=> array($this, '_filterStoreCondition'),

));

}

$this->addColumn('is_active', array(

'header' => Mage::helper('profile')->__('Status'),

'index' => 'is_active',

'type' => 'options',

'options' => array(

0 => Mage::helper('profile')->__('Disabled'),

1 => Mage::helper('profile')->__('Enabled')

));

$this->addColumn('creation_time', array(

'header' => Mage::helper('profile')->__('Date Created'),

'index' => 'creation_time',

'type' => 'datetime',

));

$this->addColumn('update_time', array(

'header' => Mage::helper('profile')->__('Last Modified'),

'index' => 'update_time',

'type' => 'datetime',

));

return parent::_prepareColumns();

}

//4

protected function _afterLoadCollection()

{

$this->getCollection()->walk('afterLoad');

parent::_afterLoadCollection();

}

//5

protected function _filterStoreCondition($collection, $column)

{

if (!$value = $column->getFilter()->getValue()) {

return;

}

$this->getCollection()->addStoreFilter($value);

}

/**

* Row click url

* @return string

//6

public function getRowUrl($row)

{

return $this->getUrl('*/*/edit', array('profile_id' => $row->getId(), 'category_id' => Mage::registry('profile_category_id') ));

}

以上函数的讲解：

6.1

public function __construct()

{

parent::__construct(); //上层构造函数调用。

$this->setId('profileBlockGrid'); //Set object id field value

$this->setDefaultSort('profile_id'); //以那个字段来排序

$this->setDefaultDir('ASC'); //升序还是降序。

}

6.2

protected function _prepareCollection()

{

$collection = Mage::getModel('profile/profile')->getCollection();

$collection->addFieldToFilter('category_id', Mage::registry('profile_category_id'));

/* @var $collection Mage_Cms_Model_Mysql4_Block_Collection */

$this->setCollection($collection);

return parent::_prepareCollection();

}

得到过滤条件后的collection，然后将_data[collection],赋值。

6.3

//3

protected function _prepareColumns()

{

$baseUrl = $this->getUrl();

$this->addColumn('content_heading', array(

'header' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'),'content_heading'),

'align' => 'left',

'index' => 'content_heading'

));

if(Mage::registry('profile_category_id') != RichardMason_Profile_Model_Profile::CATEGORY_RELEASES) {

$this->addColumn('content', array(

'header' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'),'content'),

'align' => 'left',

'index' => 'content'

));

}

if (!Mage::app()->isSingleStoreMode()) {

$this->addColumn('store_id', array(

'header' => Mage::helper('profile')->__('Store View'),

'index' => 'store_id',

'type' => 'store',

'store_all' => true,

'store_view' => true,

'sortable' => false,

'filter_condition_callback'

=> array($this, '_filterStoreCondition'),

));

}

$this->addColumn('is_active', array(

'header' => Mage::helper('profile')->__('Status'),

'index' => 'is_active',

'type' => 'options',

'options' => array(

0 => Mage::helper('profile')->__('Disabled'),

1 => Mage::helper('profile')->__('Enabled')

));

$this->addColumn('creation_time', array(

'header' => Mage::helper('profile')->__('Date Created'),

'index' => 'creation_time',

'type' => 'datetime',

));

$this->addColumn('update_time', array(

'header' => Mage::helper('profile')->__('Last Modified'),

'index' => 'update_time',

'type' => 'datetime',

));

return parent::_prepareColumns();

}

_prepareColumns()

主要应用addColumns方法：增加grid的列!

$this->addColumns("此处为在数据库中的字段名称".array())

array（

header-----在页面显示的列名

index------数据库中的字段名称

type ------在前台显示使用的小控件类型，如options（select下拉条），datetime（会显示时间控件）

store_all--是否显示所有商店。

sortable---是否可以排序，也就是在页面的字段名称处点击，然后以此字段排序的功能是否开启，flase/true.

type--------store类型，应该是根据值去对应相应的key，得到相应的value吧。

filter_condition_callback---array($this,'_filterStoreCondition')

是store_id的，对于这个，还是很模糊，先这样吧。遇到store，直接把这个赋值过去就可以了。

6.4

protected function _afterLoadCollection()

{

$this->getCollection()->walk('afterLoad');

parent::_afterLoadCollection();

}

还是不是很懂。看来想做grid，还是得摸索着做，以后再回来看奥秘。

6.5

//5

protected function _filterStoreCondition($collection, $column)

{

if (!$value = $column->getFilter()->getValue()) {

return;

}

$this->getCollection()->addStoreFilter($value);

}

为addcolumns store_id处的filter_condition_callback---array($this,'_filterStoreCondition')

对应的方法。

//6

public function getRowUrl($row)

{

return $this->getUrl('*/*/edit', array('profile_id' => $row->getId(), 'category_id' => Mage::registry('profile_category_id') ));

}

得到URL，也就是grid中每行可以通过点击该行进入编辑的URL获得，就是通过这个函数得到的！

到此，吧一个grid显示出来编写结束！主要难点为block/Profile.php文件和block/profile/Grid.php文件的编写。

附加：

parent::_addButton('add', array(

'label' => Mage::helper('profile')->getText(Mage::registry('profile_category_id'), 'New'),

'onclick' => 'setLocation(/''.$this->getUrl('*/*/edit', array('category_id' => Mage::registry('profile_category_id'))).'/')',

'class' => 'add',

));

add按钮，编写的时候模仿就可以，一切可以山寨！懂原理就可以！！
