if($_POST['registerbtn'])
{
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];

            if($getemail){


             if($getuser){

                 if($getpass){

                         }else

Answer 1

如果您在同一页面提交表格。

$form = "<form action='' method='post'>

试试这个..

if(isset($_POST['registerbtn']))

而不是

if($_POST['registerbtn'])

和如果你的Connect.php和注册在同一个文件夹中，那么如果在文件夹之外，请使用require("Connect.php");然后给出正确的路径

Answer 2

首先，除了registerbtn之外，如果没有将变量设置为“”，则需要检查变量是否已设置。

像这样：

<?php
if(isset($_POST['registerbtn']))
{
  ...

} else {
  $getuser = $getemail = $errormsg = "";
}





$form = "<form action='./register.php' method='post'>

<table>
<tr>
<td></td>
<td><font color='red'>$errormsg</font></td>
</tr>
</table>
<fieldset>
<legend>Account</legend>
<input type='text' name='user' size='15' value='$getuser'/>:Username<br/>
<input type='text' name='email' size='15'value='$getemail'>:Email<br/>
<input type='password' name='pass' size='15' value=''/>:Passcode<br/>
<input type='password' name='confirmation' size='15' value=''/>:Confirmation<br/>
<br/>
<input type='submit' name='registerbtn' value='EAT ME'/>
</fieldset>
</form>";
  echo "$form";

如果db部分没有任何问题，它应该可以工作。

在其中一个if-conditionals中：

if($numrows == 1){
}else
    $errormsg = "An Error Has Occurred. Account Not Processed";

这不是必需的，因为if($numrows == 0 )的其他人负责处理它。

Answer 3

将<form action='./register.php' method='post'>更改为<form action='' method='post'> or <form action='#' method='post'>

我无法以某种方式在我的数据库上POST文件
