提交表单只是显示自己 [英] submitted form just shows itself

问题描述

我有一个用于注册新人的表单，当我点击

提交按钮时，表单就会显示出来。如果你将字段留空等，它应该显示一个

消息显示字段错误。

提交空表单应该显示红色的错误消息，然后显示

表格，但它只是表格形式。我检查了变量，使得他们没事，他们就没事了。我相信这是一个逻辑错误

我的if else ....我通过使用函数

和相同的结果模块化了一切。

如果有人看到逻辑错误，请告诉我。这里的代码：

<？php


函数showmessage（）{

//检查以确保他们输入了有效的电子邮件地址。

if（eregi（" ^（[[：alnum：]] | _ | \。| - ）+ @（[[：alnum：]] | \。 | - ）+（\。）（[az] {2,4}）$"，

I have a form i will use to register new people and when I click the
submit button, the form just shows itself. It is supposed to show a
message showing field errors if you leave fields blank etc. so
submitting the empty form should show error message in red , then show
form, but all it does is show form. I checked the variable to make
shore they ere ok and they are fine. i believe it is a logical error
with my if else.... I eved modularized everything by using functions
and the same results.

if any one sees the logical error, let me know. Here the code:
<?php
