I’m in the middle of making this contact form and currently I’m trying to solidify the email verification. I currently have it so when the field is blank or an invalid email it shows an error message. If the email is fine, it will send me an email and also add it to a database I’ve created. So far, so good. The only issue I have is IF this email is already added to the database, I don’t want to add it again. So I’ve done this as well, and it works, the only issue is displaying the error message. The original error messages are in an array, and this last error message has to be in lines after the array so I’m not sure how to make the error message show (line 30). You’ll see on line 29 I just added echo error, this was to verify it worked. Any help would be appreciated.
code:
[code]
<?php
// if submitted
if (isset($_POST[‘submit’])) {
// gather POST data
$email = $_POST[’email’];
// make variables are empty
$error = array();
$msg = “”;
$error_msg = “”;
// validate the email entered email address
if (strlen(trim($email)) > 0) {
if (!eregi(“^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$”, $email)){
$error[’email’] = “enter a valid email”;
}
} else {
$error[’email’] = “enter your email”;
}
// if no errors with email address
if (empty($error)) {
// Open database connection
$conn = mysql_connect(‘localhost’, ‘DBUSERNAME’, ‘DBPASSWORD’);
mysql_select_db(‘DBNAME’);
// check if email is in the database already
$check_query = mysql_query(“SELECT * FROM emails WHERE email='” . $email . “‘”);
$rows = mysql_num_rows($check_query);
if ($rows > 0)
{
// display error if email is already in the database
// echo ‘ERROR’;
$error[’email’] = “Your email has already been added, try another”;
}
else {
// insert email address into database
$query = “INSERT INTO emails (email) VALUES (‘$email’)”;
mysql_query($query);
// Close connection
mysql_close($conn);
// there were no errors, display thank you message for successfully entering a valid email
$msg = “Success!n”;
// send email, display thank you message
// build the email
$to = ‘[email protected]’;
$subject = “contact form”;
$message = “$email”;
$headers = “From: $email”;
// send the mail using PHPs mail() function
ini_set(sendmail_from,’[email protected]’); // the INI lines are to force the From Address to be used
mail($to, $subject, $message, $headers);
ini_restore(sendmail_from);
}
}
else {
// there were errors, add the error class to the email input
$error_msg = “<p>”;
foreach($error as $field => $error) {
$style[$field] = ” error”;
$error_msg .= “$error”;
}
$error_msg .= “</p>n”;
}
}
// end check for submit button

Also, I was wondering if with this, do you think I’ll need to worry about spam protection since it’s pretty fool proof? or is it not? thanks again
