php - 尝试使用 php 检查 html 文本框是否为空

标签 php mysql html

我有这段代码来验证 html 文本框是否为空。但我不明白入场时间和地址有什么共同点，它们似乎不起作用。即使我在其中输入了数据，代码也不会读取它们:

   <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">

<form name="form1.1" method="POST" action="aisaction.php">

     $TELNUM = $_POST[telnum];
     $HOSPNUM = $_POST[hnum];

     $FIRSTNAME = $_POST[fname];
     $MIDNAME = $_POST[mname];
     $ADDRESS = $_POST[address];

     $ADATE = $_POST[adate];
     $ADTIME = $_POST[adtym];
     $CSTAT = $_POST[cs];
     $AGE = $_POST[age];
     $BDAY = $_POST[bday];
     $SEX = $_POST[sex];

最佳答案

第二个怎么了 <form>只包含一个隐藏的输入和一个提交按钮？该提交按钮属于外部表单。 (无论如何，表单不能嵌套。表单不能嵌套在其他表单内!)

做这个:

<form action="aisaction.php" method="POST" target="_window">
    <input type="hidden" name="submit" value="yes">
    <input type="submit" value="submit">
</form>

进入此:

<input type="hidden" name="submit" value="yes">
<input type="submit" value="submit">
