smarty高级特性之过滤器的使用方法,
本文实例分析了smarty高级特性之过滤器的使用方法。分享给大家供大家参考,具体如下:
高级特性中过滤器的使用
1、预过滤器
function remove_dw_comments($tpl_source, &$smarty) { return preg_replace("/<!--#.*-->/U","",$tpl_source); //去除原tpl文件中的注释,使其在编译后的文件中不显示 } //注册预过滤器 $smarty->register_prefilter("remove_dw_comments"); $smarty->display("test1.tpl");
test1.tpl
与过滤器的使用
注释的格式
这样的话,注释在编译后的文件中被过滤掉
2、后过滤器
function add_header_comment($tpl_source, &$smarty) { return "<?php echo \"<!-- Created by Smarty! -->\n\" ?>\n".$tpl_source; //添加头部注释 } //注册后过滤器 $smarty->register_postfilter("add_header_comment"); $smarty->display('test2.tpl');
模板文件:
test2.tpl
头部会产生注释:
3、输出滤镜
function protect_email($tpl_output, &$smarty){ $tpl_output = preg_replace('!(\S+)@([a-zA-Z0-9\.\-]+\.([a-zA-Z]{2,3}|[0-9]{1,3}))!', '$1%40$2', $tpl_output); return $tpl_output;}// register the outputfilter$smarty->register_outputfilter("protect_email"); $smarty->display("index.tpl"); } $smarty->register_outputfilter("protect_email"); $smarty->display("index.tpl");
希望本文所述对大家基于smarty模板的PHP程序设计有所帮助。
