quote item update issue in magento 1.4.1.1

2010-08-16T01:48:59-08:00

Hi, I have run into a bit of a problem with magento 1.4.1.1.
I have developed a module that creates a quote requests from the shopping cart items and sends it through to the admin.
This allows me to hide the prices and have people add products to cart with unknown prices.
Once the admin gets the quote request he can set custom prices and discounts to the quote.
The admin notifies the customer that his quote is ready and when the customer accepts the quote the products are added to his cart with the custom prices and he is allowed to go through the checkout process.
I used to use something similar to the following code to set the prices.

private function customPrice($product_id, $price){
    $cart = Mage::getModel('checkout/cart'); //Get Cart Model
    $quote = $cart->getQuote(); //Get all info of current quote
    $quote_items = $quote->getAllItems(); //Get all products in cart
    foreach($quote_items as $item){  //loop through products
      $item_id = $item->getProductId();  //Get product sku
      if($item_id == $product_id){ //Check if sku's match
        $item->setCustomPrice($price); //Set the unit price 
        $item->calcRowTotal();  //Calculate the subtotal
        $item->save;  //Update the item
      }  
    }
    $quote->getTotals(); //Recalculate all totals
    $quote->save(); //Save cart
  }

This was working in magento 1.4.0.1 but now, all custom prices gets recalculated each time the user goes to the checkout page or the cart page.
I am working on another workaround but would like to know if there is an easy way to set a custom price to a magento quote item that will stick around and not modify any settings to the actual product.
If I find a solution to this today, I will update the post to let you know how I did it.

magento 性能优化

2010-09-19T07:31:48-08:00

前言:
Magento 是一个开源电子商务系统，尤其以扩展性高著称，但是很高的扩展性往往是牺牲了速度为代价的，虽然现在magento为速度提升做了很多工作，但是还是没能达到人们对速度的要求。既然如此还是有很多企业选择了它，速度问题还是让很多客户无法接受，最近忙碌于magento性能优化。
同时速度也上了几个台阶，据本人目测最少快了(7-8倍)。

参考了合同前辈的经验总结了如下几点:
1) Magento Caching. Magento 自身cache
Goto Magento Admin -> System -> Cache Management
- Tick the following items:
– Configuration
– Layouts
– Block HTML output
– Translations

2) MySQL Cache Size 设置
query_cache_size=128M
innodb_buffer_pool_size=64M
innodb_additional_mem_pool=16M

4) Enabling Gzipping 启用gzip压缩
.htaccess
php_flag zlib.output_compression on
AddHandler application/x-httpd-php5 .css

修改 .htaccess mod_deflate 配置
本人配置如下:

# Insert filter on all content
SetOutputFilter DEFLATE
# Insert filter on selected content types only
#AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript

# Netscape 4.x has some problems…
BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

# Don’t compress images
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary

# Make sure proxies don’t deliver the wrong content
Header append Vary User-Agent env=!dont-vary

5) Install Fooman Speedster 安装该插件

6) Install APC or Xcache 安装apc机器码缓存

apc
alphanumeric

添加到 app/etc/local.xml 之间.

7) 设置apache 开启 KeepAlive

KeepAlive ＝ On

LoadModule deflate_module modules/mod_deflate.so #开启mod_deflate

Using Multiple Stores and Single Checkout

2010-08-17T06:20:11-08:00

hi,

Just wanted to know if we can use two stores and a single checkout in magento.If it is possible please do post the solution here.

My requirement is as follows,

I have two websites main-site-1 and main-site-2.

main-site -2 uses another domain.

But both the stores share the same files of magento.

Now when a customer purchases any product from main-site-2, then i want him to be redirected to the main-site-1 cart/checkout page with the cart contents of the main-site -2 to be displayed on the cart/checkout page of main-site-1.

I was able to redirect him to the main-site-1 but the contents of the cart were not getting displayed.

can anyone help me with this..?

Thanks

"Swedish" Rounding

2010-10-07T03:55:33-08:00

I would like to implement “Swedish” rounding.
http://en.wikipedia.org/wiki/Swedish_rounding

Even though it may not be necessary in e-commerce, there is a culture of using it in many countries. This is because in these countries small monetary demoninations have been removed from circulation. 1 cents / 2 cents etc.. I have a client with a brick + mortar store, they want the prices in their physical cash world to match the online store, so there is no differences for the end consumer.

It is a psychological issue IMHO, however at the end of the day we sell products to people not machines.

This should work for everything, delivery, % discounts etc.

Considering this could be an issue for a few countries I thought I would share this around as it can benefit others.

I have a rough method which is locale based, probably not 100% correct, can be done more sophisticated:

function swedishRound($price) {
    preg_match('/[A-Z][A-Z]/', Mage::app()->getLocale()->getDefaultLocale(),$matches);
    if (isset($matches) && count($matches) > 0)
    {
        switch ($matches[0])
        {
            case 'AU': //Australia
            case 'BA': //Bosnia and Herzegovina
            case 'BR': //Brazil
            case 'CH': //Switzerland
            case 'FI': //Finland    
            case 'HU': //Hungary
            case 'MY': //Malaysia
            case 'NL': //Netherlands
            case 'SG': //Singapore
            case 'ZA': //South Africa
                // 5 cent rounding
                $price = round(($price+0.000001)*20)/20;
            break;
            case 'NZ': //New Zealand
                // 10 cent rounding
                $price = round(($price+0.000001)*10)/10;
            break;
        }
    }
    return $price;
}

I am just wondering where the best place to put it would be? I am guessing just before the price gets formatted?
Though you have to make sure that runs all the way through to the final billing.
Any tips/help would be appreciated.
Missing countries (Norway/Denmark/Sweden?), others, cultural norms?

Ultimately it could be a nice free community extension.
