一个改写的表单验证类
一个改写的表单验证类
代码：
<?php
/****************************************
* FormChecker V0.3 *
* By:Terpomo Email:[email protected] *
* **************************************
* 主要函数：
* 1.增加一项验证项
* Add($id,$name,$type,$canNull=false,$max=100,$msg='',$regular='//');
* $id 要检查的表单（数组）中键值
* $name 该项的名称
* $type 类别（text/int/email/url/postcode/phponecode/usr(自定义))
* $canNull 可以为空,默认为不能
* $max 最大长度
* $msg 如果出错的提示信息，不填使用系统默认
* $regular type为user时的自定义正则表达式
* 2.检查一个数组是否符合所有人验证项
* Check($Array)
* 3.检查结果
* checkPassed 是否通过检查
* 4.错误信息
* error
* 一个简单例子
*--------------------------------------------
* <?php
* $FC = new FormChecker;
* $FC->Add('email','电子邮件','email');
* $FC->Check($_POST);
* if($FC->checkPassed){
* do some thing for the form values....
* }else{
* echo $FC->error;
* }
* ?>
* <form action=<? php_self ?> ><input type=text name=email><input type=submit></for>
*--------------------------------------------
* 注：写这个class是为了尝试如何方便的进行大量的表单的验证和处理，希望大家提出讨论的意见
