在外部使用WordPress API

用Wordpress这么久了, 从没看过文档也没用过API. 近期有如此需求, 譬如说我站内已有一个网站, 另有一个Wordpress, 两个都在一个主机上, 我希望在WordPress之外使用其API, 显示文章列表啊什么的.

发现有如下之参考: see: http://www.webopius.com/content/139/using-the-wordpress-api-from-pages-outside-of-wordpress

在php文档一开头就声明:

<?php define('WP_USE_THEMES', false); ?>
<?php require('wp-blog-header.php');?>

此后, WordPress API可用.

的确可用.

但今天在讨论Wordpress读取post的SQL时对qury进行了debug, 发现, 只要include/require了 wp-blog-heard.php就会立马辗转Call一下Classes.query_posts(), 先查询10个post再说.

分析后发现不可引用wp-blog-heard.php, 转而引用:wp-load.php就够．

因此，如果需要在站外使用API, php声明:

define('WP_USE_THEMES', false);
require 'C:\xampp\htdocs\wp\wp-load.php'; // instead of wp-blog-header.php

使用Streampad播放网页中的MP3音频文件

Categories: Development Notes • WordPress; Tagged with: WordPress; @ March 21st, 2010 17:46

无需注册，立即获得代码： http://www.streampad.com/getit#

将获得后的代码放入网页中放置妥当后， 会自动播放网页中的ｍｐ３链接．如包含:

 我这里放了个mp3链接,所以才会播放!

总之:

有两个条件:

1. js代码已放入网页中 – 播放器有了

2. 网页中包含有mp3链接- 要播放的音乐有了.

另外: 简洁直接的播放器, 尤其适合一般音乐不多的情况下:

WordPress 无法自动更新解决方法

Categories: Development Notes • WordPress; Tagged with: WordPress; @ September 10th, 2009 21:34

出现形如: “You do not have sufficient permissions to update plugins for this blog”的错误

今天帮老刘升级WordPress时出现这个错误, 很晕,据 http://wordpress.org/support/topic/230668 知:

原因在于表*options表中的user_roles 数据不准确, 如你也碰到此类问题, 又想启用自动更新, 你可拷贝以下将你的覆盖掉.

WordPress播放器

Categories: Development Notes • WordPress; Tagged with: WordPress; @ May 10th, 2009 21:43

今天录了段音, 想放上来, 想搞个稍微花哨的播放器. 顺手找到的俩假单的, look:

1. 使用站点: http://www.blogcastone.net/ 填入mp3地址, 然后加入生成的代码

2. 直接使用flash的player, 手动改代码其实也慢方便的:

如: Google Reader的:

使用Windows Live Writer发布日志

Categories: Development Notes • WordPress; Tagged with: WordPress; @ November 12th, 2008 11:46

作为一款本地Blog管理工具，Windows Live Writer 支持大部分主流的Blog接口，包括RSD、Metaweblog API和Movable Type API等。通过WLW可以方便的在博客中插入图片,视频等多媒体, 以及表格,链接等常规内容.并且支持通过代理服务器发布博客.

WLW可以完美的支持WordPress,包括目录选择, 增加目录, Tag, 是否允许评论, 作者,密码, 摘要等.
在安装完毕WLW后, 选择Weblog/Add Weblog Account,增加一个博客:

如果时WordPress，选择最后一个．

填入博客地址，用户名及密码既可．

如果需要使用代理,点击Edit Proxy…
现在就可以使用WLW写博客啦:

好用的功能:

1. 直接拖入图片作为附件. 设置图片的位置及效果.
2. 三种视图,非常方便在Source视图中可以查看或修改代码. 在PREVIEW视图中预览
3. 展开下方的输入框, 可以增加目录,设定Tag, 摘要等.
4. 离线发布: 无网络时使用WLW, 待有网络时候发布

Windows Live Writer Beta 使用了许多与 Microsoft Office 相同的键盘快捷方式。常见操作快捷键如下：

将当前文章发布到博客：CTRL+SHIFT+P

打开新文章： CTRL+N

将草稿保存到计算机上： CTRL+S

切换到“普通”视图： CTRL+F11

切换到“Web 版式”：视图 F11
