smarty中的这个数组如果理解呀
$arr|api:'cases':'getInfoList':"where pass=1^ ORDER BY topflag DESC,submit_date DESC^0^8^id,title,thumbnail,bedeck^^0"

在BIweb中的这数组怎么理解呀??

------解决方案--------------------
给lz找个手册上的例子 :{$articleTitle|truncate:30:"":true} 意思是把$articleTitle变量传入truncate方法中,附带三个参数30、""、true,然后返回截取后的结果
如果能看懂上面的例子,lz就应该很清楚了,api是自定义函数,后接三个用 ':' 隔开参数
'|'符号是类似于管道的功能,将$arr传给api函数,返回经过处理的结果
参考下面的文章:

------解决方案--------------------
变量调节器用于变量,自定义函数和字符串。使用‘|’符号和调节器名称应用调节器。变量调节器由赋予的参数值决定其行为。参数由‘:’符号分开。

Smarty模板引擎中的自定义函数放在插件目录(plugins)下,内建函数写在smarty本身的语法里面。自定义函数可以任意修改,任意添加,内建函数则不然。

我们可以在plugins目录下自定义函数文件,但必须严格按照smarty的函数命名规范,以便我们在调用自定义函数的时候,smarty才能够在plugins下找到。

接下来,我们将定义两个自定义函数:
函数stredit用于对字符串的大小写转换操作
函数jiequ用于对字符串进行截取操作

 命名规范:
变量调节器文件名必需以modifier开头,后面接上自定义函数名:如modifier.stredit.php,modifier.jiequ.php
变量调节器函数名的命名必需以smarty_modifier_开头,后接上自定义函数名:如smarty_modifier_stredit()、smarty_modifier_jiequ()

自定义字符串操作函数

1The basic unit of Unicode computer storage is the byte, which is composed of 8 bits. Since English only consists of 26 letters plus a number of symbols, English characters can be stored directly in bytes. But other languages ​​(such as Chinese, Japanese, Korean, etc.) have to use multiple bytes for encoding due to the large number of characters. With the spread of computer technology, non-Latin character encoding technology continues to develop, but there are still two major limitations: no multi-language support: the encoding scheme of one language cannot be used in another language and there is no unified standard: for example There are many encoding standards in Chinese such as GBK, GB2312, GB18030, etc. Since the encoding methods are not unified, developers need to convert back and forth between different encodings, and many errors will inevitably occur.

What are the similarities and differences between __str__ and __repr__? We all know the representation of strings. Python's built-in function repr() can express objects in the form of strings to facilitate our identification. This is the "string representation". repr() obtains the string representation of an object through the special method __repr__. If __repr__ is not implemented, when we print an instance of a vector to the console, the resulting string may be. >>>classExample:pass>>>print(str(Example()))>>>
