[SOLVED] please help me with the error message for my registration form

[littlepeg]

Hi, everybody. I am a new learner for php & MySQL. I try to develop a registration form, but it could not work.  ???The error message is as follows:

    "Cannot modify header information - headers already sent by (output started at  C:\wamp\www\snyp\snypdb.php:20) in C:\wamp\www\snyp\bookdsfds.php on line 66"

  Could you please help me to sort out this problem. Any help would be grately and appreciated.

 

  The code as follows:

 

<?php # Script 8.7 - bookdsfds.php

// Send NOTHING to the Web browser prior to the header() line!

 

// Check if the form has been submitted.

if (isset($_POST['submitted'])) {

 

require_once ('snypdb.php'); // Connect to the db.

 

$errors = array(); // Initialize error array.

 

// Check for a first name.

if (empty($_POST['first_name'])) {

$errors[] = 'You forgot to enter your first name.';

} else {

$fn =$_POST['first_name'];

}

 

// Check for a last name.

if (empty($_POST['last_name'])) {

$errors[] = 'You forgot to enter your last name.';

} else {

$ln = $_POST['last_name'];

}

 

// Check for an email address.

if (empty($_POST['email'])) {

$errors[] = 'You forgot to enter your email address.';

} else {

$e = $_POST['email'];

}

 

// Check for a password and match against the confirmed password.

if (!empty($_POST['password1'])) {

if ($_POST['password1'] != $_POST['password2']) {

$errors[] = 'Your password did not match the confirmed password.';

} else {

$p = $_POST['password1'];

}

} else {

$errors[] = 'You forgot to enter your password.';

}

 

if (empty($errors)) { // If everything's OK.

 

// Register the user in the database.

 

// Check for previous registration.

$query = "SELECT user_id FROM users WHERE email='$e'";

$result = mysql_query($query);

if (mysql_num_rows($result) == 0) {

 

// Make the query.

$query = "INSERT INTO users (first_name, last_name, email, password, registration_date) VALUES ('$fn', '$ln', '$e', SHA('$p'), NOW() )";

$result = @mysql_query ($query); // Run the query.

if ($result) { // If it ran OK.

 

$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);

 

// Check for a trailing slash.

if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) {

$url = substr ($url, 0, -1); // Chop off the slash.

}

 

// Add the page.

$url .= '/funder.php';

header("Location: $url");

exit();

 

} else { // If it did not run OK.

$errors[] = 'You could not be registered due to a system error. We apologize for any inconvenience.'; // Public message.

$errors[] = mysql_error() . '<br /><br />Query: ' . $query; // Debugging message.

}

 

} else { // Email address is already taken.

$errors[] = 'The email address has already been registered.';

}

 

} // End of if (empty($errors)) IF.

 

mysql_close(); // Close the database connection.

 

} else { // Form has not been submitted.

 

$errors = NULL;

 

} // End of the main Submit conditional.

 

if (!empty($errors)) { // Print any error messages.

echo '<h1 id="mainhead">Error!</h1>

<p class="error">The following error(s) occurred:<br />';

foreach ($errors as $msg) { // Print each error.

echo " - $msg<br />\n";

}

echo '</p><p>Please try again.</p>';

}

// Create the form.

?>

<h2>Register</h2>

<form action="bookdsfds.php" method="post">

<p>First Name: <input type="text" name="first_name" size="15" maxlength="15" value="<?php if (isset($_POST['first_name'])) echo $_POST['first_name']; ?>" /></p>

<p>Last Name: <input type="text" name="last_name" size="15" maxlength="30" value="<?php if (isset($_POST['last_name'])) echo $_POST['last_name']; ?>" /></p>

<p>Email Address: <input type="text" name="email" size="20" maxlength="40" value="<?php if (isset($_POST['email'])) echo $_POST['email']; ?>"  /> </p>

<p>Password: <input type="password" name="password1" size="10" maxlength="20" /></p>

<p>Confirm Password: <input type="password" name="password2" size="10" maxlength="20" /></p>

<p><input type="submit" name="submit" value="Register" /></p>

<input type="hidden" name="submitted" value="TRUE" />

</form>

 

this is the php file the error message mentioned:

// codes for snypdb.php

 

<?php

 

$strLocation="Home";

//$strLocation="University";

 

if($strLocation=="Home"){

  $dbLocalhost=mysql_connect("localhost","root","")

or die("could not connect:" .mysql_error());

}

 

else{

  $dbLocalhost=mysql_connect("osiris.sunderland.ac.uk","bc2tzh","bc2tzh")

  or die("could not connect:" .mysql_error());

}

 

mysql_select_db("snyp", $dbLocalhost)

or die("could not find detabase:" .mysql_error());

?>
