Wordpress文章URL优化,seo优化

Wordpress有自定义URL的机制来进行URL优化
,可以自由设定Wordpress
文章的URL地址。

如,//sjolzy.cn/Article-URL-Wordpress-optimization-seo-optimization.html

这个URL组成形式为:http://域名/文章标题.html

实现方法:后台 settings > Permalinks > Common settings

选择Custom Structure:填入/%postname%.html

或者多一级目录形式的:/%category%/%postname%.html

这样就能对Wordpress博客的文章进行URL优化了,从而达到seo优化
效果。。

PS,设置完后如果出现Wordpress 403错误的话,参考:Wordpress出现403 Forbidden错误

Magento - 添加订单退货模块

参考水水兄的文章:http://blog.csdn.net/shuishui8310/archive/2010/04/27/5532992.aspx

ps, 水水兄高人风范,,很多地方都一语带过, 下午应朋友需求增加订单退货模块,跟着做了一下.. 略微详细记录过程。

无图,图片党边参照水水兄的文章。

1./app/code/core/Mage/Sales/etc/config.xml
搜索statuses,加入<refunding translate="label"><label>On Refunding
</label></refunding> 
再在下面的states加入
    <refunding>
        <statuses>
            <refunding/>
        </statuses>
    </refunding>

2./app/locale/en_US/Mage_Sales.csv 打开这个语言文件 >> 其他语言包的自己翻译相应加入
搜索Payment Review,换个行加入"On Refunding","On Refunding",到这步骤在后台就能看到On Refunding这个退货的订单状态了(清下缓存)

3.在前台http://domain.com/customer/account/index/,新增可供客户点击的“退货”链接
app/design/frontend/base/default/template/sales/order/recent.phtml搜索View Order在大概65行加入
<?php if ($_order->getStatus()=='complete') : ?>
    <span class="separator">|</span> <a href="#" class="link-reorder"><?php echo $this->__('On Refunding') ?></a>
<?php endif ?>
自己下个订单测试,改成完成状态后便可以有退货的链接。

4.在app/code/core/Mage/Sales/controllers/OrderController.php里加个函数
    /*将客户完成的订单的订单状态改退货中*/
    public function refundingAction(){
        $orderId = (int) $this->getRequest()->getParam('order_id');
        if (!$orderId) {
            $this->_forward('noRoute');
            return false;
        }
        $order = Mage::getModel('sales/order')->loadByIncrementId($orderId);
        if ($this->_canViewOrder($order)&&$order->getStatus()=='complete') {    // 验证符合
            $order->setData('status','refunding');
            $order->save();
        }
    $this->_redirect('*/*/history');    // 这里提示的 相应再自己修改
    }
这时候通过访问:http://www.chaussay.com/sales/order/refunding/order_id/100000002
就可以把该客户的完成的订单改变成退货中。

至此Magento增加订单退货的整个流程结束。。

Magento调试 - 页面空白,打开错误报告的方法

问题:Magento页面一片空白
没显示什么东西,无法判断是否程序错误,所以要把错误显示打开使之能调试

解决:

1. 在网站根目录的.htaccess文件里加上

php_flag display_errors on
php_value error_reporting 2039
详情看另外一篇文章:(用.htaccess设置 PHP错误显示
)

2. 然后找到/errors/local.xml.sample这个文件,改成/errors/local.xml

3. 接着找到lib/Zend/Cache/Backend/File.php

查找 protected $_options = array( ’cache_dir’ => ‘null’,

替换成 protected $_options = array( ’cache_dir’ => ‘tmp/’,

4. 最后在/index.php文件里把error_reporting(E_ALL | E_STRICT)
;和ini_set('display_errors', 1)
;注释取消。可以再加上Mage::setIsDeveloperMode(true)
;这句配合第二点把magento的开发模式打开

这几步下来Magento的错误报告
就打开啦!

MYSQL应用 - 自定义排序,字段置顶等

在MYSQL数据库查询时,排序是经常用到的一个功能。单纯按照某字段排序查询较为简单,无非就是order by `field` (DESC/ASC)。如:

1SELECT * FROM `table`

2ORDER BY `field` DESC

注:上面的table换成要查询的表名,field换成要排序的字段名,DESC表示从大到小,去掉则从小到大。

下面介绍几个复杂一点的应用:

自定义排序

需求:查询table表,取出id为1,5,9,7的记录,并按1597的顺序显示.

解决:

1SELECT * FROM `table`

2WHERE id in(1,5,7,9)

3ORDER BY FIELD(`id`,1,5,9,7) //注意FIELD后面无空格

文章置顶

需求一:查询文章表table,取出所有文章,但字段zj为1的记录置顶(均以time字段排序,time大的 放在前面)。

解决一:

1SELECT * FROM `table`

2ORDER BY `zj` DESC,`time` DESC

解决二:

1SELECT * FROM `table`

2WHERE zj=1

3ORDER BY `time` DESC

4UNION

5SELECT * FROM `table`

6WHERE zj!=1

7ORDER BY `time` DESC

需求二:查询文章表table,取出所有文章,置顶ID为1、5、12、2的文章,并按上述顺序显示。

解决:

 

1SELECT * FROM `table`

2ORDER BY FIELD(`zj`,1,5,12,2) DESC,`time` DESC

没有胶片的光线

三年前写的一篇文章,今天偶然在好友空间找回,贴回来。

 

 突然知道,已经好几年没认真照过相了。
      
于是。

那几年的似乎美好时光终于像没有在胶片上感光并留下痕印而夭夭逃去的光线。


在我的视界里拉出长长的模糊白色点点。

留下没有什么。就像终究没过认真照相。

就像糖是甜的唇是红的没带光线的胶片是不感人的一样。自然。

蜘蛛啊爬虫啊太勤劳了。。

大前天写了一篇,抓取蜘蛛爬虫痕迹的文章,之后就根据写的代码在本站上测试。

经过两天的时间,来发表一下对一些搜索引擎的爬虫蜘蛛的看法。。

整天24小时几乎都有爬虫过来爬。。那些大咔的和小咔的。其中sogou最积极。。

下面截取上午到下午几小时内的记录:
