SQL Syntax Error - Php regiform

foreverandeveralone · March 24, 2012

Hi there!

Thanks for your time, and thank you for taking a look at my post, I really hope you can help me out

I just started on php, and I'm currently trying to develop a login/registration system. The login part works fine, but I'm getting this mysql error when i execute my registration code:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''users' ('username', 'password', 'email', 'name') VALUES ('test','098f' at line 1

I have been trying to troubleshoot this for hours now, and decided to turn to professionals :shrug:

Below is my code and explanations for the registration.

(register.php) The visual part. There shouldn't be any bugs here.

<?php session_start();?>

<html>
<head>
<title>SHAT Registration</title>
<link rel="stylesheet" type"text/css" href="style.css">
</head>

<body>
<div class="loginform">
<center>
<img src="logo.png">
<h3> -the only place thats cool enough</h3>
<br>
</center>

<?php
if (!isset($_SESSION['uid'])) {
echo "<p>Please Register or <a href='index.php'>Log in</a></p>";
} else {
header( 'Location: shat.php' ) ;
}

?>

<table border="0" cellspacing="3" cellpadding="3">
<form method="post" action="registration.php">
<tr><td>Username</td><td><input type="text" name="username"></td></tr>
<tr><td>Password</td><td><input type="password" name="password"></td></tr>
<tr><td>Confirm</td><td><input type="password" name="passconf"></td></tr>
<tr><td>E-mail</td><td><input type="text" name="email"></td></tr>
<tr><td>Name</td><td><input type="text" name="name"></td></tr>
<tr><td colspan="2" align="center"><input type="submit" name="submit" value="Register!"></td></tr>
</form></table>

</div>
</body>
</html>

(functions.php) The security and connection code.

<?php

function protect ($string) {
$string = mysql_real_escape_string($string);
$string = strip_tags ($string);
$string = addslashes($string);

return $string;

}

function connect () {
$con = mysql_connect("localhost", "root", "lol123") or die (mysql_error());
$db = mysql_select_db("login", $con);
}

?>

(registration.php) The main part, errorcheck insert etc.

<?php
include_once "functions.php";

connect();

$username = protect ($_POST['username']);
$password = protect ($_POST['password']);
$confirm = protect ($_POST['passconf']);
$email = protect ($_POST['email']);
$name = protect ($_POST['name']);

$errors = array();


	if (!$username) {
		$errors[] = "Username is not defined!?";
		}

		if (!$password) {
		$errors[] = "Password is not defined!?";
		}

		if ($password) {
			if (!$confirm) {
			$errors[] = "Confirmation password is not defined!?";
			}
		}

		if (!$email) {
			$errors[] = "E-mail is not defined!?";
			}

		if (!$name) {
			$errors[] = "Name is not defined!?";
			}

			if($username) {
				if(!ctype_alnum ($username)) {
					$errors[] = "Username can only contain numbers and letters!";
					}
				$range = range(1,32);
				if(!in_array(strlen($username),$range)){
				$errors[] = "Username too long!";
            }
        }

		if($email){
			$checkemail = "/^[a-z0-9]+([_\\.-][a-z0-9]+)*@([a-z0-9]+([\.-][a-z0-9]+)*)+\\.[a-z]{2,}$/i";
				if(!preg_match($checkemail, $email)){
				$errors[] = "E-mail is not valid, must be [email protected]!";
				}
			}

		if($name){
            $range2 = range(3,64);
            if(!in_array(strlen($name),$range2)){
                $errors[] = "Your name might be to short... or too long! How long is your name really niggurh?!";
            }
        }

	if ($username) {
		$sql = "SELECT * FROM users WHERE username ='($username)'";
		$res = mysql_query($sql) or die (mysql_error());

			if(mysql_num_rows($res) > 0) {
				$errors[] = "The username is already taken!";
				}
	}
	if($email){
		$sql2 = "SELECT * FROM users WHERE email='($email)'";
		$res2 = mysql_query ($sql2) or die (mysql_error());
			if(mysql_num_rows($res2) > 0) {
			$errors[] = "E-mail is already registered!";
		}
	}

	if (count($errors) > 0){
		foreach($errors AS $error){
			echo $error . "<br>\n";
		}
		}else {
			$sql4 = "INSERT INTO 'users'
			('username', 'password', 'email', 'name')
			VALUES ('".$username."','".md5($password)."','".$email."','".$name."')";

			$res4 = mysql_query ($sql4) or die (mysql_error());
			echo "<b>".$username."</b>, you have successfully registered! Welcome to SHAT! Please <a href='index.php'>log in</a>";

			}

?>

Mysql info

Database: Login
Table: users
Columns: id, username, password, email, name

Now this genius can tell that my problem is related to my, mysql. I just don't know how to fix it, I feel like Ive tried everything.

If anyone could help me with this, or give some advice, or maybe just link to a related post, I would appreciated it very much!

the problem is here you have 'users' when it should just be users

$sql4 = "INSERT INTO 'users'
			('username', 'password', 'email', 'name')
			VALUES ('".$username."','".md5($password)."','".$email."','".$name."')";

And when you post sql queries be sure to remove database usernames and passwords from the code you put up

Thank you for the reply ! although it gave me a new error

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''username', 'password', 'email', 'name') VALUES ('test','098f6bcd4621d373ca' at line 2

But now i know what section my problem is in.

I still can't seem to figure out how to fix it... maybe I should get of the computer for a couple of hours and return...

try replacing that line with this

$passInsert = md5($password);
$sql4 = "INSERT INTO users (username, password, email, name) VALUES ('$username','$passInsert','$email','$name')";

I like your usage of different font sizes, colors and images to convey your issue/emotions to us.

Just kidding.

I know it may seem immature. But it breaks the everyday formal-straightforward-black&white-way-of-communication. Which tends to be the norm of many boards like this. I mean it's good and all, and very professional, but it gets really boring and "dry" in many cases
