Help getting registration script working. No errors, no update to my db


Recommended Posts

Hi all,


I am working on a site that requires registration, and login to access certain content. I am having trouble debugging the code as no errors pop up when i hit register, and nothing happens on the backend. The php code that I have so far is here:


include ('dbc.php'); 

if ($_POST['submit'] == 'register')
   if (strlen($_POST['email']) < 5)
    die ("Incorrect email. Please enter valid email address..");
   if (strcmp($_POST['pword1'],$_POST['pword2']) || empty($_POST['pword1']) )
//die ("Password does not match");
die("ERROR: Password does not match or is empty..");

if (strcmp(md5($_POST['user_code']),$_SESSION['ckey']))
		 die("Invalid code entered. Please enter the correct code as shown in the Image");
$rs_duplicates = mysql_query("select userId from CUser where email='$_POST[email]'");
$duplicates = mysql_num_rows($rs_duplicates);

if ($duplicates > 0)
//die ("ERROR: User account already exists.");
header("Location: register.php?msg=ERROR: User account already exists..");

$username = $_Post['userId'];
$md5pass = md5($_POST['pass2']);
$fname = $_Post['fname'];
$lname = $_Post['lname'];
$email= $_Post['email'];
$activcode = rand(1000,9999);
$joined = now();
$activated = 1;
$school = $_Post['CSU'];
$as = $_Post['areaofstudy'];
$emph = $_Post['emph'];
$server = $_SERVER['HTTP_HOST'];
$host = ereg_replace('www.','',$server);
$command = "INSERT INTO CUser".
			"(userId, pword2, fname, lname, email,activation_code,".
			"joined, user_activated, schoolId, asCode, emphcode)".
			"('$username', '$md5pass', '$fname', '$lname', '$email', '$activcode', ".
			"'$joined', '$activated', '$school', 'as', 'emph')";
mysql_query($command) or die(mysql_error());

$message = 
"Thank you for registering an account with $server. Here are the login details...\n\n
User Email: $_POST[email] \n
Password: $_POST[pass2] \n
Activation Code: $activ_code \n
*** ACTIVATION LINK ***** \n
Activation Link: http://$server/activate.php?usr=$_POST[email]&code=$activ_code \n\n
Thank you. This is an automated response. PLEASE DO NOT REPLY.

mail($_POST['email'] , "Login Activation", $message,
    "From: \"Auto-Response\" <notifications@$host>\r\n" .
     "X-Mailer: PHP/" . phpversion());
echo("Registration Successful! An activation code has been sent to your email address with an activation link...");

the registration button is the only live link and takes you to the register.php which is the code posted above. If anybody can help out I would greatly appreciate it! Thanks in advance for your time

It is on register.php along with the code I previously posted. It comes after the php code. Is that normal practice? Thanks again for your time

Ok, so I have made some progress and was hoping someone could help out with my new issues. I changed the setup a bit, instead of the form action calling register.php it calls $_SERVER

[php_SELF]. This works, the system sends an email when registering, but I get a mysql error "Duplicate entry '0' for key 1" on the next page. The entries are not being added to db, yet it also says successfully registered, and I get an email with the correct activation link etc. I decided to echo $command like suggested before and this is what it output:
INSERT INTO CUser(userId, pword2, fname, lname, email,activation_code,joined, user_activated, schoolId, asCode, emphcode)VALUES('', 'd41d8cd98f00b204e9800998ecf8427e', '', '', '', '1713', now(), '1', '', 'as', 'emph')


It doesnt seem as if the query is correct. If anyone could help out I would greatly appreciate it!

Ok, I removed userId and made it auto increment. I am still getting syntax error though. This is what the user table looks like:

| Field           | Type        | Null | Key | Default | Extra          |
| userId          | int(11)     |      | PRI | NULL    | auto_increment |
| username        | varchar(20) | YES  | MUL | NULL    |                |
| pword1          | varchar(32) | YES  |     | NULL    |                |
| pword2          | varchar(32) | YES  |     | NULL    |                |
| fname           | varchar(20) | YES  |     | NULL    |                |
| lname           | varchar(20) | YES  |     | NULL    |                |
| email           | varchar(20) | YES  |     | NULL    |                |
| activation_code | varchar(50) | YES  |     | NULL    |                |
| joined          | date        | YES  |     | NULL    |                |
| user_activated  | int(1)      | YES  |     | NULL    |                |
| schoolid        | int(11)     | YES  |     | NULL    |                |
| ascode          | int(11)     | YES  |     | NULL    |                |
| emphcode        | int(11)     | YES  |     | NULL    |                |
| notifId         | int(11)     | YES  |     | NULL    |                |
| externCode      | int(1)      | YES  |     | NULL    |                |
15 rows in set (0.00 sec)


Here is the error I am getting now:


You have an error in your SQL syntax near ' d41d8cd98f00b204e9800998ecf8427e, , , , 6374, now(), 1, , , )' at line 1



This is what is output by echoing $command:


INSERT INTO CUser(username, pword2, fname, lname, email, activation_code,joined, user_activated, schoolId, asCode, emphcode)VALUES(, d41d8cd98f00b204e9800998ecf8427e, , , , 6374, now(), 1, , , )




I am wondering why the values being inserted are blank, let me know if you can think of what I am doing wrong. I appreciate it! Thanks
