错误：字段列表中的未知列

Question

While running the below script it shows the errorError: Unknown column 'email' in 'field list'.

  <?php
  include("connect.php");

  if($loggedin == '1')
  die("You can't register another account while you're logged in.");

  if(isset($_POST['submit']))
  {

  $uname = trim($_POST['username']);

 if($_POST["regkey"]!="171717")
 die("Invalid Registration Key. <br> <a href= register.php>Back</a>");

 if($_POST["pass"]!=$_POST["pass2"])
 die("Passwords do not match. <br> <a href= register.php>Back</a>");

 // Make sure all forms were filled out.

 if((!isset($_POST['username'])) || (!isset($_POST['pass']))
 || ($uname == '') || ($_POST['pass'] == ''))
 die("Please fill out the form completely. <br><br>
 <a href=register.php>Continue</a>");


 $check = @mysql_query("SELECT id FROM players WHERE username = '$uname'");
 $check = @mysql_num_rows($check);

 if($check > 0)
 die("Sorry, that username has already been taken. Please try again.
 <br><br>
 <a href=register.php>Continue</a>");


 $pass = md5($_POST['pass']);

 $date = date("m/d/y");


 $newPlayer = @mysql_query("INSERT INTO players (username, password,   

registered,callname,email) VALUES   ('$uname','$pass','$date','$_POST

[callname]','$_POST[email]')") or die("Error: ".mysql_error());

echo 'You have been registered! You may now <a href=index.php>Log in</a>.';


}
else
{

// A simple example of a form.

echo '
<center>
<form action=register.php method=post>
<p>Registration is currently<b> NOT OPEN.</b><br>
 You must have a valid Registration key to register.</p>
 <table border="2">
 <tr>
<td>Username:</td><td><input type="text" name="username" size="20px"</input>
</td>
</tr>
<tr>
<td>Callname:</td><td><input type="text" name="callname" size="20px"</input>
</td>
</tr>
<tr>
<td>Password:</td><td><input type="password" name="pass" size="20px"</input>
</td>
</tr>
<tr>
<td>Re-type Password:</td><td><input type="password" name="pass2" size="20px"</input>  
</td>  </tr>
<tr>
<td>Email:</td><td><input type="text" name="email" size="20px"</input></td>
</tr>
<tr><td>Registration Key:</td><td><input type="text" name="regkey" size="20px"></input>                                                                                         

 </td>    </tr>
 </table>
 <input type="submit" name="submit" value="Submit"></input>
 </form>';

 }


 ?>

I'm very new to PHP and can't figure out why I'm getting this Error. Shouldn't the $_POST get that value from the form? Thanks for reading.

Answer 1

It means your players table does not contain an email column. You will need to add this column to your table for this script to work.

So the incorrect part in your code is

$newPlayer = @mysql_query("INSERT INTO players(username, password, registered, callname, email)
                           VALUES('$uname', '$pass', '$date', '$_POST[callname]', '$_POST[email]')") or die("Error: ".mysql_error());
