WordPress:WPMU List All Blogs Widget

This code is the code needed to create a widget to show a list of all blogs. It is dependent on the plug-in List-All, that should be installed first. Create a blank text file named widget_list_all.php in your plugins folder, add the following php code. You should then be able to activate the List All plugin and the List-All-Blogs Widget on the plugins tab. Then look over in the presentation/widgets tab and you should have a new widget named List All Blogs Widget.

需要这个代码，创建widget显示所有博客的列表。取决于插件List-All，应该先安装这个插件。在你的插件文件夹中创建名为widget_list_all.php的空白文本文件，添加下面的php代码。然后你就能够激活插件标签上的List All插件和List-All-Blogs Widget。然后查看呈现/widget标签，你应该有个新的称为All Blogs Widget的widget。
