  • Style Magento checkout form fields without touching the core code

    Although I can change css complete restyle the checkout forms, this is not what I want to discuss today. What I want to achieve are:

    1. fix City required asterisk not showing bug
    2. change Address lines from full width to half width as City

    The City required asterisk is hidden by a javascript wrongly. I found City and State/County/Province are put into one li, i.e. <li><div></div></li>. It might be something should happen on State/County/Province but happens on City. If I close li after City, and reopen it before State/County/Province, bug is fixed. By the way, I hide State/County/Province.

    To show a field in full length, Magento uses
    <li><label><span></span></label><input/></li>
    To show a field in half length, Magento uses
    <li><div><label><span></span></label><input/></div></li>

    So just find the right place to insert <div> and close it for Address lines, I easily style them to the same length of City.

  • Magento idea: business intelligence

    It is very time consuming to set Related Products, Cross Sells, Up Sells on individual product basis, and not accurate if you work them out just using your brain. It is good to see Magento has these marketing terms built in, but I hate to do the job by hand (or brain).

    So I am thinking of developing a business intelligence module for Magento to let computer work Related Products, Cross Sells, Up Sells for us.

    Here is the overview of this module:

    First, we need record more data than what Magento provides. we specify a period of data to data-mine.

    Then, for Related Products, mine product pageviews by each visit. Put a visitor’s all visited products into an array, and count all visitors’ arrays for every product-product combination.

    As for Cross Sells, mine orders received or fulfilled. The algorithm is similar to Related Products.

    As for Up Sells, mine the products were added to cart but dropped from final order. Compare the product dropped with the products in final order, and if the former is of higher value, and some sort related to the latter, we can call the former Up Sells. This is my definition, and the algorithm is some sort complicated.

  • Chrome for Linux

    今天无意中发现 Google 有了 Linux 版的 Chrome，赶紧下载来装。以前也有 Linux 版的 Chrome，但要自己编译，我吃不消，盼望给我一个 rpm 很久。我在 Fedora 本来只有 Firefox 可用，偶尔用一下 Konqueror，但不顺手，所以 Firefox 挺寂寞的。

    Google 是开源先锋，我认为早就可以出 Linux 版的 Chrome 了，可是还是先出了 Windows 版的，到底还是 Windows 用户多嘛，用户至上，无可厚非。
