<?php $TYPE = getcache('type_content','commons');?>
然后在循环里写：
<a href="index.php?m=content&c=type&catid={$catid}&typeid={$r[typeid]}">{$TYPE[$r[typeid]][name]}</a>
这样就可以调用出来类别了，不过链接暂时无效，因...
Django templates: verbose version of a choice
...
In Django templates you can use the "get_FOO_display()" method, that will return the readable alias for the field, where 'FOO' is the name of the field.

How can I have linebreaks in my long LaTeX equations?
...can be precisely controlled. e.g.
\begin{align*}
x&+y+\dots+\dots+x_100000000\\
&+x_100000001+\dots+\dots

Use 'import module' or 'from module import'?
... * can be particularly useful, if using it as: if(windows):\n\t from module_win import * \n else: \n\t from module_lin import *.
