由于表单肩负着交互的重要使命，所以处理表单就成了xajax的必修课了，对于我个人的经验，看一下本站的评论xajax是如何处理的。

由于本站使用了smarty模版，对于一些不熟悉smarty模版的朋友增加了理解的难度，所以在这个例子中我不使用类和smarty等其他工具，只作简单阐述，力求能够理解方法

<?php error_reporting(E_ALL ^ E_NOTICE); define('ROOT_PATH',str_replace("\\","/",dirname(__FILE__))); //载入xajax类 require_once(ROOT_PATH . '/includes/xajax/xajax.inc.php'); //处理评论提交 function postcomment($form) { global $db,$tablefix; $objResponse = new xajaxResponse(); $errormsg = array(); $UserName = xml_escape($form['UserName']); $Email = xml_escape($form['Email']); $Words = xml_escape($form['Words']); $BlogID = xml_escape($form['BlogID']); $IsConfirmed = 0; $badkey = "非法关键字|非法"; if(empty($Email)){ //如果没有填写电子邮件则替换容器标签为Emailmsg内的内容为email必须填写 $objResponse->addAssign("Emailmsg","innerHTML","email必须填写"); } if(empty($UserName)){ $errormsg['UserName'] = "姓名必须填写"; $objResponse->addAssign("UserNamemsg","innerHTML",$errormsg['UserName']); } if(empty($Words)){ $objResponse->addAssign("Wordsmsg","innerHTML","内容必须填写"); } if(preg_match("/$badkey/i",$Words)){ $errormsg['Words'] = "内容可能含有敏感字符"; $objResponse->addAssign("Wordsmsg","innerHTML",$errormsg['Words']); } if(!is_numeric($BlogID) OR $BlogID <= 0){ $objResponse->addAppend("Wordsmsg","innerHTML","未知错误"); } if(count($errormsg)>0){ $objResponse->addAssign("addsubmit","value","发表留言"); $objResponse->addAssign("addsubmit","disabled",false); }else{ //没有错误则插入数据 //这里是你处理提交进数据库 //清空表单 $objResponse->addAssign("UserName","value",""); $objResponse->addAssign("Email","value",""); $objResponse->addAssign("Words","value",""); //添加提示信息 $objResponse->addAssign("addsubmit","value","如继续评论请刷新页面"); $objResponse->addAssign("successmsg","innerHTML","评论已经成功添加，但仍需要审核才会显示出来"); } return $objResponse; } $xajax = new xajax(); //$xajax->debugOn(); $xajax->registerFunction("postcomment"); $xajax->processRequests(); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>xajax留言评论处理例子</title> <?php echo $xajax->getJavascript($CONFIG['ROOT_PATH'] .

主要用于过滤特殊符号.

我是xajax新手,看到这上面的例子,我想知道

xml_escape 这个函数是从哪里得来,或者是不是自己定义的
