我有以下注册代码-
<?php
// Connects to your Database
mysql_connect("my serner", "user", "password") or die(mysql_error());
mysql_select_db("ec09580") or die(mysql_error());
//This code runs if the form has been submitted
if (isset($_POST['submit'])) {
//This makes sure they did not leave any fields blank
if(isset($_POST['firstname']) && isset($_POST['lastname']) && isset($_POST['email']) && isset($_POST['username']) && isset($_POST['pass1']) && isset($_POST['pass2']))
{
$fname = $_POST['firstname'];
$lname = $_POST['lastname'];
$email_id = $_POST['email'];
$username_r = $_POST['username'];
$password_1 = $_POST['pass'];
$password_2 = $_POST['pass2'];
// checks if the username is in use
if (!get_magic_quotes_gpc()) {
$_POST['username'] = addslashes($_POST['username']);
}
$usercheck = $_POST['username'];
$check = mysql_query("SELECT username FROM User WHERE username = '$usercheck'")
or die(mysql_error());
$check2 = mysql_num_rows($check);
//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');
}
// this makes sure both passwords entered match
if ($_POST['pass'] != $_POST['pass2']) {
die('Your passwords did not match. ');
}
// here we encrypt the password and add slashes if needed
$_POST['pass'] = md5($_POST['pass']);
if (!get_magic_quotes_gpc()) {
$_POST['pass'] = addslashes($_POST['pass']);
$_POST['username'] = addslashes($_POST['username']);
}
}
// now we insert it into the database
$insert = "INSERT INTO User set FirstName='$fname', LastName='$lname', Email='$email_id', username='$username_r', password='$password_1'";
$add_member = mysql_query($insert);
?>
<h1>Registered</h1>
<p>Thank you, you have registered - you may now login</a>.</p>
<?php
}
else
{
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<table border="0">

<input type="text" name="firstname" maxlength="60">

<?php
}
?>
对于激活,我有以下代码 -
<?php
if (isset($_GET['x'])) {
$x = (int) $_GET['x'];
} else {
$x = 0;
}
if (isset($_GET['y'])) {
$y = $_GET['y'];
} else {
$y = 0;
}
if ( ($x> 0) && (strlen($y) == 32)) {
require_once ('mysql_connect.php');
$query = "UPDATE User SET active=NULL WHERE (id=$x AND active='" . $y . "') LIMIT 1";
$result = mysql_query($query);
if (mysql_affected_rows() == 1) {
echo "<h3>Your account is now active. You may now log in.</h3>";
} else {
echo '<p><font color="red" size="+1">Your account could not be activated. Please re-check the link or contact the system administrator.</font></p>';
}
mysql_close();
} else {
echo '<b>Activation link not valid!</b>';
}
?>
我不断收到此错误--
注意:未定义变量:第 87 行 /var/www/users/ec09580/project_test/r_test.php 中的 fname 注意:未定义变量:第 87 行 /var/www/users/ec09580/project_test/r_test.php 中的 lname 注意:未定义变量:第 87 行 /var/www/users/ec09580/project_test/r_test.php 中的 email_id 注意:未定义变量:第 87 行 /var/www/users/ec09580/project_test/r_test.php 中的 username_r 注意:未定义变量:第 87 行 /var/www/users/ec09580/project_test/r_test.php 中的 password_1
我很困惑该怎么办。谁能帮帮我吗?谢谢你。
