Smarty缓存机制 $smarty->display(

阅读更多关于 Smarty缓存机制 $smarty->display(

Smarty缓存机制大家应该知道缓存机制能有效的减轻网站的服务器压力，Smarty模板引擎的一大亮点就是为我们提供了非常简单的缓存操作，下面就让我们学习一下。　　首先我们要知道Smarty缓存机制分为全局缓存，部分缓存，局部缓存三种，我们一一介绍。　　1、全局缓存　　顾名思义，全局缓存就是为整个网站的全部页面都生成缓存页面。首先我们要操作smarty的配置文件，开启缓存，指定缓存文件目录，并设置缓存的存活时间　　$smarty->cache_dir = './cache/'; //设置存放缓存文件的文件夹 $smarty->caching = 1; //开启缓存 0、FALSE代表关闭|非0数字、TRUE代表开启 $smarty->cache_lifetime = 3600; //单位为秒(如果填写-1为永不过期) 　　接下来我们要去具体的php页面设置与之对应的具体缓存文件的名字　　$url=md5($_SERVER['REQUEST_URI']); //将当前页面的URL(包含?后面的所有参数)进行md5加密 $smarty->display('list2.html',$url); //设置缓存文件名　　需要注意的是：　　$smarty->display('与之对应的模板文件名','缓存文件名的补充部分') 这个方法。　　第二个参数不是必须的，如果不写的话

问题 Assigning from PHP: $smarty->assign("myArrays", Array( Array( "title" => "ABC", "whatever" => 45), Array( "title" => "DEF", "whatever" => 78) )); In Smarty (v3.1.16) .tpl file: {assign "seperator" "|"} {foreach from=$myArrays item=currentItem} {$seperator}{$currentItem.title}{$seperator} {/foreach} Then it will output as: |ABC| |DEF| ..

问题 I'm having difficulty throwing away the bits of the expression I don't want, and keeping the bits I do. The problem is - given the input string: {if cond}foo{else}bar{/if} I'd like just to have: 0: {if cond}foo{else}bar{/if} 1: cond 2: foo 3: bar And for the input string: {if cond}foo{/if} I'd like just to have: 0: {if cond}foo{else}bar{/if} 1: cond 2: foo 3: The regex I've got at present looks like this: \{if ([a-z0-9]+)\}([^\{]*?)(((?:\{else\})?)(.*?)?)\{/if\} I get the following data back:

阅读更多关于 A voting system with jQuery, PHP and Smarty

I have made a voting feature to my website using only PHP and Smarty. This's the HTML part of it: <p>{$vote} <a href="vote.php?q_vote=vote_up&question_id={$qid}"><i class="icon-thumbs-up"></i></a> <a href="vote.php?q_vote=vote_down&question_id={$qid}"><i class="icon-thumbs-down"></i></a></p> The PHP part of the code takes the vote and refreshes the same page. I want to do the same thing using jQuery so that it won't need to refresh the page.

Assigning defaults for Smarty using Object Oriented style

阅读更多关于 Assigning defaults for Smarty using Object Oriented style

问题 I'm just very slowly starting to sink into object-oriented programming, so please be gentle on me. I have a custom class for Smarty that was partially borrowed. This is how the only example reflects the basic idea of using it across my current project: class Template { function Template() { global $Smarty; if (!isset($Smarty)) { $Smarty = new Smarty; } } public static function display($filename) { global $Smarty; if (!isset($Smarty)) { Template::create(); } $Smarty->display($filename); } Then

问题 I'm trying to use jsmart to render Smarty3 templates on the client-side. If you've no experience with them, keep reading because it could just be a simple JavaScript error that I'm making. It works for simple templates: I create the template (which I receive via AJAX), then render it (passing it the data), as per the documentation: var template = new jSmart(templateReceivedViaAJAX); var content = template.fetch({"firstname":"adam", "secondname":"lynch"}); Then I simply stick the rendered
