下面是发送邮件给作者的model，可有可无 

app\code\local\Iverve\Uploadpdf\Model
app\code\local\Iverve\Uploadpdf\Model\Extensioncheck.php
class Iverve_Uploadpdf_Model_Extensioncheck extends Mage_Core_Model_Abstract
{
public function _construct()
{
parent::_construct();
$this->_init('uploadpdf/extensioncheck');
}   
}

下面是sql文件，用于自动添加对应的数据表，如果没有添加，自己按照代码来手动添加对应的表

<?php

$installer->startSetup();
$installer->run("

   CREATE TABLE {$this->getTable('uploadpdf/uploadpdf')}(

	  `pdf_file` varchar(500) NULL,

if(!$installer->tableExists('uploadpdf/extensioncheck')){
