delete-----magento后台数据信息删除----------

在grid里面实现这个方法：

protected function _prepareMassaction()

{

$this->setMassactionIdField('post_id');

$this->getMassactionBlock()->setFormFieldName('blog');

$this->getMassactionBlock()->addItem('delete', array(

'label' => Mage::helper('gao')->__('Delete'),

'url' => $this->getUrl('*/*/massDelete'),

'confirm' => Mage::helper('gao')->__('Are you sure?')

));

$statuses = Mage::getSingleton('blog/status')->getOptionArray();

array_unshift($statuses, array('label'=>'', 'value'=>''));

$this->getMassactionBlock()->addItem('status', array(

'label'=> Mage::helper('blog')->__('Change status'),

'url' => $this->getUrl('*/*/massStatus', array('_current'=>true)),

'additional' => array(

'visibility' => array(

'name' => 'status',

'type' => 'select',

'class' => 'required-entry',

'label' => Mage::helper('blog')->__('Status'),

'values' => $statuses

)

)

));

return $this;

}
