smarty 替换多个值

问题描述

我有包含这一行的 ..tpl 文件:

I have ..tpl file with this line:

{$error|replace:"pno":"personal number error"}

我需要修改它以便替换多个值，例如:

I need to modify it so multiple values will be replaced, sort of:

{$error|replace:"pno_error":"personal number error", "error_1":"1", "error_2":"2"}

我需要确保代码格式正确.我如何实现这一目标?

I need to make sure the code is correctly formed. How do I achieve this?

推荐答案

像这样

{assign "find" array('pno', 'error_1', 'error_2')}
{assign "repl" array('personal number error', 1, 2)}
{assign "text" 'error_1 and pno and error_2 are friends'}
{$text|replace:$find:$repl}

顺便说一句:不要通过控制器来做，在 tpl 文件中使用最终值?

btw: dont'cha rather do it through a controller and in tpl files use final values?

编辑

如何使它只替换完全匹配，例如如果$text 是'pno'，则替换它，但如果$text 是'pnopno'，则什么都不做?

在这种情况下，您可以使用正则表达式，但是，在数组中是不可能的(据我所知)，您需要一步一步地进行，或者更确切地说是一个命令后的命令.

In that case, you can use regular expressions, however, it is not possible in an array (as far as I know) and you need to do it step by step, or rather a command after command.

关于替换pno而不是pnopno，您需要找出适合您需要的正则表达式.

Regarding of replacing pno and not pnopno, you need to figure out your own regular expression to suit your needs.

{assign "text" 'error_1 and pno and error_2 are friends'}
{$text|regex_replace:"/(\s)(pno)(\s)/":"personal number error"|regex_replace:"/(error_1)/":"1"|regex_replace:"/(error_2)/":"2"}
