让你的Smarty更聪明_PHP教程

一、扩展你的Smarty 1、准备功夫 PHP代码:-------------------------------------------------------------------------------- function Smarty_function_page ( $params, &$Smarty ) { $href = #; $space = ; $frist = NULL; $last = NULL; $page = 5; extract($params); if ( !$row || $row <= 1 ) return ; $pages = $row; $curr_page = $now ? $now : 1; $offset = 2; $from = $curr_page - $offset; $to = $curr_page + $page - $offset - 1; if ( $page > $pages ) { $from = 1; $to = $pages; } else { if ( $from < 1) { $to = $curr_page + 1 - $from; $from = 1; if ( ( $to - $from ) < $page && ( $to - $from ) < $pages ) { $to = $page; } } elseif ( $to > $pages ) { $from = $curr_page - $pages + $to; $to = $pages; if ( ( $to - $from ) < $page && ( $to - $from) < $pages ) { $from = $pages - $page + 1; } } } if ( $frist && ( $curr_page - 1 ) >= 1 ) $p[frist] = . $frist . ; if ( $prev && ( $i = $curr_page - 1 ) >= 1 ) $p[prev] = . $prev . ; for( $i = $from; $i <= $to; $i ++ ) { if ( $i == $curr_page ) { $p[$i] = [ . $i . ]; } else { $p[$i] = . $i . ; } } if ( $next && ( $i = $curr_page + 1 ) <= $pages ) $p[next] = . $next . ; if ( $last && ( $curr_page + 1 ) <= $pages ) $p[last] = . $last . ; return implode( $space, $p ); } // end func -------------------------------------------------------------------------------- 将上面的代码命名为"function.page.php"保存到Smarty的plugins目录里 代码:-------------------------------------------------------------------------------- {page row=10} {page row=10 now=5} {page row=10 now=5 href=DownloadFilesa2004-11-02"plugins.php$a=1&b=2&page=" frist="第一页" prev="上一页" next="下一页" last="最后页"} {page row=10 now=5 href=DownloadFilesa2004-11-02"plugins.php$a=1&b=2&page=" frist="第一页" prev="上一页" next="下一页" last="最后页"} {page row=10 now=1 href=DownloadFilesa2004-11-02"plugins.php$a=1&b=2&page=" frist="第一页" prev="上一页" next="下一页" last="最后页"} {page row=10 now=10 href=DownloadFilesa2004-11-02"plugins.php$a=1&b=2&page=" frist="第一页" prev="上一页" next="下一页" last="最后页"} -------------------------------------------------------------------------------- 将上面的代码命名为"plugins.html"保存到Smarty的template目录里 2、测试程序 PHP代码:-------------------------------------------------------------------------------- $Smarty->display( plugins.html ); -------------------------------------------------------------------------------- 3、使用说明 我懒得打了，对比一下"plugins.html"的5个{page}用法，以及看看显示出来的效果就明白是什么了 4、插件说明 “《Smarty手册》第十六章.以插件扩展Smarty ”的应用。像中文字符截取之类的都可以以plugins扩展Smarty，Smarty自带的截取不支持中文。 __________________ 二、Smarty自动生成静态页面 如果你的文件扩展名为".html"~~~~~嘿嘿，这不就是静态页面了吗？-_-! 至于怎么取得静态的文件名呢？ PHP代码:-------------------------------------------------------------------------------- /** * */ class template extends Smarty { /** * */ function template () { $this->Smarty(); } // end func /** * */ function name ( $tpl_file, $cache_id = null, $compile_id = null ) { if (!isset($compile_id)) $compile_id = $this->compile_id; $_auto_id = $this->_get_auto_id( $cache_id, $compile_id ); $_cache_file = $this->_get_auto_filename( $this->cache_dir, $tpl_file, $_auto_id ); return basename( $_cache_file ); } // end func } // end class $Smarty = new template; $file_name = $Smarty->name( plugins.html, cache_name );#html文件的名字(不包含路径) $Smarty->cache_lifetime = -1;#静态文件永不过期 $Smarty->fetch( plugins.html, cache_name );#生成静态html文件 这是村里翻译的，实际上Smarty的应用还远不止于此。 One of the unique aspects about Smarty is the template compling. This means Smarty reads the template files and creates PHP scripts from them. Once they are created, they are executed from then on. Therefore there is no costly template file parsing for each request, and each template can take full advantage of PHP compiler cache solutions such as Zend Accelerator (http://www.zend.com) or PHP Accelerator (http://www.php-accelerator.co.uk). Smarty的特点之一是"模板编译"。意思是Smarty读取模板文件然后用他们创建php脚本。这些脚本创建以后将被执行。因此并没有花费模板文件的语法解析,同时每个模板可以享受到诸如Zend加速器(http://www.zend.com) 或者PHP加速器(http://www.php-accelerator.co.uk)。这样的php编译器高速缓存解决方案。 Some of Smartys features: Smaty的一些特点: It is extremely fast. 非常非常的快! It is efficient since the PHP parser does the dirty work. 用php分析器干这个苦差事是有效的 No template parsing overhead, only compiles once. 不需要多余的模板语法解析,仅仅是编译一次 It is smart about recompiling only the template files that have changed. 仅对修改过的模板文件进行重新编译 You can make custom functions and custom variable modifiers, so the template language is extremely extensible. 可以编辑自定义函数和自定义变量,因此这种模板语言完全可以扩展 Configurable template delimiter tag syntax, so you can use {}, {{}}, , etc. 可以自行设置模板定界符,所以你可以使用{}, {{}}, , 等等 The if/elseif/else/endif constructs are passed to the PHP parser, so the {if ...} expression syntax can be as simple or as complex as you like. 诸如 if/elseif/else/endif 语句可以被传递到php语法解析器,所以 {if ...} 表达式是简单的或者是复合的,随你喜欢啦 Unlimited nesting of sections, ifs, etc. allowed. 如果允许的话,section之间可以无限嵌套 It is possible to embed PHP code right in your template files, although this may not be needed (nor recommended) since the engine is so customizable. 引擎是可以定制的.可以内嵌php代码到你的模板文件中,虽然这可能并不需要(不推荐) Built-in caching support 内建缓存支持 Arbitrary template sources 独立模板文件 Custom cache handling functions 可自定义缓存处理函数 Plugin architecture 插件体系结构
