I want to create a login member area for a website. This is the form I use to log in:
<table width="300" border="0"
align="center" cellpadding="0"
cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form name="form1" method="post" action="/mainsite/home/login/validate_login.php">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>Member Login
</strong></td>
</tr>
<tr>
<td width="78">Username</td>
<td width="6">:</td>
<td width="294"><input
name="myusername" type="text"
id="myusername"></td>
</tr>
<tr>
<td>Password</td>
<td>:</td>
<td><input name="mypassword"
type="text" id="mypassword"></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td><input type="submit" name="Submit"
value="Login"></td>
</tr>
</table>
</td>
</form>
</tr>
</table>
So I have this code for the page that the form data gets sent to
<?php
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name
$tbl_name="members"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username",
"$password")or die("cannot connect");
mysql_select_db("$db_name")or
die("cannot select DB");
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail
about MySQL injection)
$myusername =
stripslashes($myusername);
$mypassword =
stripslashes($mypassword);
$myusername =
mysql_real_escape_string($myusername);
$mypassword =
mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name
WHERE username='$myusername' and
password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and
$mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword
and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>
However, when I try to log in, it gives me this error:
Fatal error: Call to undefined function session_register() in /home/scaledtothee/public_html/mainsite/home/login on line 33
What does this mean?
