Trying to check if html text box is empty using php
I have this code to verify whether an html text box is empty or not. But I can't figure out what common with admission time and address, that they don't seem to work. The code is not reading them even if I have inputted a data on them:
<html>
<head>
<title>Admission Information Sheet</title>
<meta http-equiv="Content-Type" content="text/html; Western (ISO-8859-1)">
<meta name="author" content=" ">
<title>
<style>
input { font-size: 16px;}
</style>
<?php include('header.php'); ?>
<div id="main_content">
</div>
<?php include('footer.php'); ?>
<table border="1" width="900" border="0" align="left" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">

What's up with the second <form> containing just a hidden input and a submit button? That submit button belongs in the outer form. (Forms can't be nested, anyhow. No forms inside of other forms!)
Make this:
<form action="aisaction.php" method="POST" target="_window">
<input type="hidden" name="submit" value="yes">
<input type="submit" value="submit">
</form>
into this:
<input type="hidden" name="submit" value="yes">
<input type="submit" value="submit">
加载中,请稍侯......
