Help with mysql form

ReeceSayer · May 9, 2009

Im creating a login/register form in php for my uni work but i can't seem to get my registration to write to my table.

Below is the form code:

<?php 
require_once "header.php"; 
?>
<html>
	<form action="authenticate.php" method="POST">
		<label>First Name: </label><br>
		<input type="text" name="FirstName" id="FirstName"><br>
		<label>Second Name: </label><br />
		<input type="text" name="SecondName" id="SecondName"><br>
		<label>House Number: </label><br>
		<input type="number" name="HouseNumber" id="HouseNumber"><br>
		<label>Address: </label><br>
		<input type="text" name="Address" id="Address"><br>
		<label>Address Line 2: </label><br>
		<input type="text" name="AddressLine2" id="AddressLine2"><br>
		<label>Town: </label><br />
		<input type="text" name="Town" id="Town"><br>
		<label>City: </label><br>
		<input type="text" name="City" id="City"><br>
		<label>Post Code: </label><br />
		<input type="text" name="PostCode" id="PostCode"><br>
		<label>Username: </label><br>
		<input type="text" name="username" id="username"><br>
		<label>Password: </label><br />
		<input type="password" name="password" id="password"><br>
        <label>Confirm: </label><br>
        <input type="password" name="password2" id="password2"><br>
        <label>Email address:</label><br>
        <input type="text" name="email" id="email"><br>
		<input type="submit" name="submit" id="submit" value="Submit"> <a href="login.php"> Login </a>
	</form>
</html>
<?php 
require_once "footer.php"; 
?>

and this is the php:

<?php 
require_once "header.php"; 
// Include the database connection file.
include("connection.php");
// Check if a person has clicked on submit.
if(isset($_POST['submit'])) { 

if(empty($_POST['username']) || empty($_POST['password']) || empty($_POST['password2']) || empty($_POST['email'])) {
	echo "You have to fill in everything in the form."; // Display the error message.
	header("Location: register.php"); // Redirect to the form.
	exit; // Stop the code to prevent the code running after redirecting.
} 

// Create variables from each $_POST.
$username = $_POST['username'];
$password = $_POST['password'];
$password2 = $_POST['password2'];
$email = $_POST['email'];
$FirstName = $_POST['FirstName'];
$SecondName = $_POST['SecondName'];
$HouseNumber = $_POST['HouseNumber'];
$Address = $_POST['Address'];
$AddressLine2 = $_POST['AddressLine2'];
$Town = $_POST['Town'];
$City = $_POST['City'];
$PostCode = $_POST['PostCode'];

// Now, compare passwords and check if they're the same.

if($password != $password2) {
	// If the passwords are NOT the same. Again display an error message and redirect.
	echo "Sorry, wrong password.";
	header("Location: register.php");
	exit;
}
// Secure the password using an md5 hash.
$password = md5($password);

// Create a variable containing the SQL query.
$query = "INSERT INTO `users` (username, password, email) VALUES ('$username', '$password', '$email')";
$query2 = "INSERT INTO `customerinfo` (FirstName, SecondName, HouseNumber, Address, AddressLine2, Town, City, PostCode) VALUES ('$FirstName', '$SecondName', '$HouseNumber', '$Address', '$AddressLine2', '$Town', '$City', '$PostCode')";
// Perform the SQL query on the database.
$result = mysql_query($query);
$result2 = mysql_query($query2);
// If the query failed, display an error.
if(!$result && !$result2) { 
	echo "Registration failed because of " . mysql_error() . "<br>"; // The dot seperates PHP code and plain text.
	echo "<a href=\"register.php\"> Try Again By Returning To The Registration Screen</a>";
} else {
	// Display a success message!
	echo "Welcome " . $username . " You are now registered";
	echo "<a href=\"login.php\"> Continue To Login!</a>";
}
}
require_once "footer.php"; 
?>
      </div>
      <!-- Footer Section -->
       <div id="footer">
         <p>Created by <a href="metitsolutions.html">Met It Solutions</a></p>
      </div>

   </div> 
   <!-- end container -->
</body>
</html>

I didn't write this code but i have tried to edit it to suit my needs... Thanks

Which table doesn't it INSERT to? There are two, 'users' and 'customerinfo'.

Also, change this line to:

   if(!$result || !$result2) {

|| - meaning OR, will check if either query failed, rather than both. Reason being is that your if wouldn't execute if 1 of the queries was successful and one failed.

Also, what exactly happens? You should try to echo things out to see where your script actually goes.

its the customerinfo table that it doesn't insert to, the insert into users works perfectly.

Ive just changed the && to an || and i get no difference, maybe that part of the script doesn't work?

When I click submit on the form i get the message "Welcome RSayer You Are Now Registered" plus the next echo just like it should... so i guess the session is still remembering me.

The table 'customerinfo' contains the following:

userID : INT(11) : Auto-Increment

FirstName : VARCHAR(255)

SecondName : VARCHAR(255)

HouseNumber : INT(2)

Address : VARCHAR(255)

AddressLine2 : VARCHAR(255)

Town : VARCHAR(255)

City : VARCHAR(255)

PostCode : VARCHAR(255)

Not sure wether that will help.

I think this is ok but not 100% as its the first time I've used either php or mysql

Thanks again

Echo $query2 right underneath the string, to see what is actually being passed.

Also change this line to:

   $result2 = mysql_query($query2) or die(mysql_error());

This will tell you if the query is failing.

ReeceSayer · May 9, 2009

i added the line:

$result2 = mysql_query($query2) or die(mysql_error());

i also wrote in the echo... not sure if this is right or where you suggested:

	echo "Welcome " . $username . " You are now registered";
	echo "<a href=\"login.php\"> Continue To Login!</a>";
	echo $query2;

The outcome is still the same... i get a success message but no actual result in my database.

Thanks for the quick replies btw... its like 3.30am over here lol

echo $query2;

What does that print out?

ReeceSayer · May 9, 2009

Nothing... theres only the same success message... does that mean that the query failed?

I just tried to test it by typing the following into the mysql run bar for the database:

INSERT INTO `customerinfo` (FirstName, SecondName, HouseNumber, Address, AddressLine2, Town, City, PostCode) VALUES ('Reece', 'Sayer', '18', 'Rushymoor', 'Askern', 'Doncaster', 'Yorkshire', 'DN60NG');

This worked out fine...

1. Does this echo do much?

   if(empty($_POST['username']) || empty($_POST['password']) || empty($_POST['password2']) || empty($_POST['email'])) {
      echo "You have to fill in everything in the form."; // Display the error message.
      header("Location: register.php"); // Redirect to the form.
      exit; // Stop the code to prevent the code running after redirecting.
   }

It seems to me that if you have the header there, the user will barely see the echo. Same with all the other echo followed by a redirect header. I could be wrong. :-\

2. Maybe an entry is messing up the quotes. Can you use mysql_real_escape_string on each $_POST data? It also prevents SQL injection. It goes like -

$username = mysql_real_escape_string($_POST['username']);

Thanks For Your Help Everyone!! I've managed to sort it out... it was a case of me being an idiot and keeping to many backups and things open in notepad++ i had 2 files called authenticate.php in seperate locations but it was the wrong one running in my apache server... so i just dragged and dropped the other 1 to replace the old one and it worked fine... sorry to have wasted your time & thanks again!!
