<?php
//We check if the form has been sent
if(isset($_POST['username'], $_POST['password'], $_POST['passverif'], $_POST['email'], $_POST['avatar']) and $_POST['username']!='')

//We remove slashes depending on the configuration
if(get_magic_quotes_gpc())
{
$_POST['username'] = stripslashes($_POST['username']);
$_POST['password'] = stripslashes($_POST['password']);
$_POST['passverif'] = stripslashes($_POST['passverif']);
$_POST['email'] = stripslashes($_POST['email']);
$_POST['avatar'] = stripslashes($_POST['avatar']);
$_POST['mobile'] = stripslashes($_POST['mobile']);
}
//We check if the two passwords are identical
if($_POST['password']==$_POST['passverif'])

Answer 1

on successful form submission you need to write code for your mail functionality
<?php
if(isset($_POST['submit'])){
$to = $_POST['email'];
$subject = $_POST['name'];
$message = $_POST['message'];
$from = "test#testcom";
$headers = "From:" . $from;
if(mail($to,$subject,$message,$headers))
{
echo "Mail Sent.";
}
else
{
echo "Something went wrong";
}
}
?>

Answer 5

Thank you all for your help.
I have successfully added a simple mail function with the help you all have contributed, here is what i did:
I added
mail($email,'Subject','Message_body');
after
if(mysql_query('insert into users(id, username, password, email, avatar, signup_date) values ('.$id.', "'.$username.'", "'.$password.'", "'.$email.'", "'.$avatar.'", "'.time().'")'))
{
//We dont display the form
$form = false;
just like this:
mail("$email",'Welcome To Naijabloom','Dear user, <br /> Welcome to Naijabloom.com, you will start receiving mails from us to keep you updated. Remember to be active in our forums and invite your friends here. Thanks. <br /> Naijanloom Team.', 'info#naijabloom.com');
and it worked for me, thanks
