demo.tpl
使用insert函数使模板一部分不被缓存
<br><{$file}><{$str}><br>
<div>这里是insert更新部分<{insert name="get_current_time"}></div>
<br>
使用register_function阻止内容从缓存输出
<div>这里是register_function函数更新部分<{current_time}></div>
<br>
使用register_block使用整篇页面的某一块区域不被缓存
<div>
Page created: <{"0"|date_format:"%D %H:%M:%S"}>
<{dynamic}>
Now is:<{$now}>
<{/dynamic}>
</div>
<table border="1">
<{assign var="Color" value="#ff0000"}>
<Tr>
<TD colspan="2">色彩:<{$Color}></Td>
</Tr>
<{section name=loop loop=$log}>
<{if $Color == "#ff0000"}>
<tr bgcolor="<{$Color}>">
<{assign var="Color" value="#CCCCCC"}>
<{else $Color == "#CCCCCC"}>
<tr bgcolor = "<{$Color}>">
<{assign var="Color" value="#ff0000"}>
<{/if}>
<td><{$log[loop].logid}></td>
<td><{$log[loop].title}></td>

要对smarty库作修改。
修改libs/Smarty_Compiler.class.php第721行：
if($tag_command == 'ywnocache') {
$this->_plugins['block'][$tag_command] = array($plugin_func, null, null, null, false);
} else {
$this->_plugins['block'][$tag_command] = array($plugin_func, null, null, null, true);
}
在libs/plugins中添加一文件:block.cacheless.php
<?php
function smarty_block_dynamic($param, $content, &$smarty) {
return $content;
}
?>
