Magento中如何调用SQL语句------magento----摘来的其他不错的!

1.Magento运行出现错误的解决方法

Magento根目录下的lib/Varien/Simplexml中的config.php文件，在顶段加上error_reportting(0);来屏蔽php的错误或异常捕捉就行了，不过，只是在Warning提示时才好用，如果时Error的话建议另辟蹊径

2.How to get currency symbol?

Here’s another way that might work for you:

Mage::app()->getLocale()->currency(Mage::app()->getStore()->

getCurrentCurrencyCode())->getSymbol()

or if you want to pass a certain currency code simply specify it:

Mage::app()->getLocale()->currency(’EUR’)->getSymbol()

Magento中如何调用SQL语句

I 创建表结构和测试数据

create table rooms(id int not null auto_increment, name varchar(100), primary key(id));

insert into rooms values(1,'Royal Room');

insert into rooms values(2,'Standard Room');

II.创建 controllers/RoomController.php:

源码copy to clipboard打印？

1. <?php

2. class Cartz_Hotel_RoomController extends Mage_Core_Controller_Front_Action{

3. public function listingAction() {

4. $handle = Mage::getSingleton('core/resource')->getConnection('core_write');

5.

6. $query = $handle->query('select name from rooms');

7. while ($row = $query->fetch()) {

8. $row = new Varien_Object($row);

9. echo "<strong>" . $row->getName() . "</strong><br/>";

10. }

11.

12. }

13. }?>

<?php class Cartz_Hotel_RoomController extends Mage_Core_Controller_Front_Action{

public function listingAction() {

$handle = Mage::getSingleton('core/resource')->getConnection('core_write');

$query = $handle->query('select name from rooms');

while ($row = $query->fetch()) {

$row = new Varien_Object($row);

echo "<strong>" . $row->getName() . "</strong><br/>";

}

}

}

?>

在地址栏中输入: http://localhost/magento/index.php/hotel/room/listing, 页面将输出:

Royal Room

Standard Room
