Hey thanks for the reply. I'm having some troubles with my email validator however. When I hit submit, I keep getting the error "Enter a Valid Email", even if the email address is valid. There is something wrong with my structure but I can't figure it out. Here is the code I'm working with. The area that is having trouble is:
PHP Code:
//////////// Email Validation ////////////
function validEmail($email)
{
$isValid = true;
$atIndex = strrpos($email, "@");
if (is_bool($atIndex) && !$atIndex)
{
$isValid = false;
}
else
{
$domain = substr($email, $atIndex+1);
$local = substr($email, 0, $atIndex);
$localLen = strlen($local);
$domainLen = strlen($domain);
if ($localLen < 1 || $localLen > 64)
{
// local part length exceeded
$isValid = false;
}
else if ($domainLen < 1 || $domainLen > 255)
{
// domain part length exceeded
$isValid = false;
}
else if ($local[0] == '.' || $local[$localLen-1] == '.')
{
// local part starts or ends with '.'
$isValid = false;
}
else if (preg_match('/\\.\\./', $local))
{
// local part has two consecutive dots
$isValid = false;
}
else if (!preg_match('/^[A-Za-z0-9\\-\\.]+$/', $domain))
{
// character not valid in domain part
$isValid = false;
}
else if (preg_match('/\\.\\./', $domain))
{
// domain part has two consecutive dots
$isValid = false;
}
else if
(!preg_match('/^(\\\\.|[A-Za-z0-9!#%&`_=\\/$\'*+?^{}|~.-])+$/',
str_replace("\\\\","",$local)))
{
// character not valid in local part unless
// local part is quoted
if (!preg_match('/^"(\\\\"|[^"])+"$/',
str_replace("\\\\","",$local)))
{
$isValid = false;
}
}
if ($isValid && !(checkdnsrr($domain,"MX") || checkdnsrr($domain,"A")))
{
// domain not found in DNS
$isValid = false;
}
}
return $isValid;
}
if (validEmail($email)==false){
$proerror = "Enter a Valid Email";
}
else{
//////////// End Email Validation /////////
$update = "UPDATE `users` SET `fname`='$fnamenew', `lname`='$lnamenew', `email`='$emailnew' WHERE `username`='$username'";
mysql_query($update);
$success = "Success!";
}
And here is my entire code:
PHP Code:
<?php
session_start();
if (isset($_SESSION['username'])){
include('inc/connect.php');
$username = isset($_SESSION['username']) ? $_SESSION['username'] : '';
$edit = (isset($_POST['edit']));
$passchange = (isset($_POST['passchange']));
if (!empty($username))
{
//if user is logged in
$sql = mysql_query("SELECT * FROM `users` WHERE `username`='$username'");
$row = mysql_fetch_assoc($sql);
$dbfname = $row['fname'];
$dblname = $row['lname'];
$dbemail = $row['email'];
$dbpassword = $row['password'];
$passcapture = $_POST['password'];
$password = md5($passcapture);
$error = "";
$proerror = "";
if ($edit)
{
$fnamenew = mysql_real_escape_string(strtolower(strip_tags($_POST['fname'])));
$lnamenew = mysql_real_escape_string(strtolower(strip_tags($_POST['lname'])));
$emailnew = mysql_real_escape_string(strip_tags($_POST['email']));
//////////// Email Validation ////////////
