例3.6 数字范例
[coolcode]
{$foo+1}
{$foo*$bar}
{* some more complicated examples *}
{* 一些更复杂的例子 *}
{$foo->bar-$bar[1]*$baz->foo->bar()-3*7}
{if ($foo+$bar.test%$baz*134232+10+$b+10)}
{$foo|truncate:”`$fooTruncCount/$barTruncFactor-1`”}
{assign var=”foo” value=”`$foo+$bar`”}

注意复杂等式中的函数{math}。 |
| Escaping Smarty Parsing |
避开Smarty解析 |
| It is sometimes desirable or even necessary to have Smarty ignore sections it would otherwise parse. A classic example is embedding Javascript or CSS code in a template. The problem arises as those languages use the { and } characters which are also the default delimiters for Smarty. |
有时候让Smarty忽略其他的对块的解析是需要的乃至必须的。一个经典的例子是在模板Javascript或者CSS代码中。问题在于这些语言使用{和}字符，而它们也是Smarty默认的定界符。 |
| The simplest thing is to avoid the situation altogether by separating your Javascript and CSS code into their own files and then using standard HTML methods to access them. |
完全避免这种情况最简单的方法，是通过分割你的Javascript和CSS代码到它们自己的文件中，使用标准的HTML方法访问它们。 |
| Including literal content is possible using {literal} .. {/literal} blocks. Similar to HTML entity usage, you can use {ldelim},{rdelim} or {$smarty.ldelim} to display the current delimiters. |
使用{literal} .. {/literal}块包含文字内容是可以的，像HTML实体使用，你可以使用{ldelim}、{rdelim}或者{$smarty.ldelim}来显示当前的定界符。 |
| It is often convenient to simply change Smarty’s $left_delimiter and $right_delimiter. |
简单地改变Smarty的$left_delimiter和$right_delimiter是非常方便的。 |
Example 3.7. changing delimiters example
例3.7 改变定界符范例
[coolcode]
left_delimiter = ‘‘;
$smarty->assign(‘foo’, ‘bar’);
$smarty->display(‘example.tpl’);
