Awesome 1st step to email validation.

Test for Manuel Lemos's PHP E-mail validation class

<?php
require("email_validation.php");

$validator=new email_validation_class;

/*
* If you are running under Windows or any other platform that does not
* have enabled the MX resolution function GetMXRR() , you need to
* include code that emulates that function so the class knows which
* SMTP server it should connect to verify if the specified address is
* valid.

* If possible specify in this array the address of at least on local
* DNS that may be queried from your network.

/* how many seconds to wait before each attempt to connect to the
destination e-mail server */

/* how many seconds to wait for data exchanged with the server.
set to a non zero value if the data timeout will be different
than the connection timeout. */
$validator->data_timeout=0;

/* user part of the e-mail address of the sending user
([email protected] in this example) */

destination mail server */

displayed properly in a HTML page. */
$validator->html_debug=1;

/* When it is not possible to resolve the e-mail address of
destination server (MX record) eventually because the domain is
invalid, this class tries to resolve the domain address (A
record). If it fails, usually the resolver library assumes that
could be because the specified domain is just the subdomain
part. So, it appends the local default domain and tries to
resolve the resulting domain. It may happen that the local DNS
has an * for the A record, so any sub-domain is resolved to some
local IP address. This prevents the class from figuring if the
specified e-mail address domain is valid. To avoid this problem,
just specify in this variable the local address that the
resolver library would return with gethostbyname() function for
invalid global domains that would be confused with valid local
domains. Here it can be either the domain name or its IP address. */

Re: Awesome 1st step to email validation.

Of course - I must be fair and say that I did not write this... I just thought it was worth sharing.

Re: Awesome 1st step to email validation.

you should write were they should but put into and what files!

Re: Awesome 1st step to email validation.

That's interesting... I don't have DNS.php either.

Sorry - I felt the file descriptions at the top were sufficient for what to do...

First File: email_validation.php - This is the actual class that checks the email address - put this in your class folder.

Second File: getmxrr.php - you probably won't need this one, I didn't. I is a replacement function if your PHP was compiled w/o getmxrr. If you need it, I'd suggest putting in your class folder as well.

Third File: Test file - you can name it whatever you want.

Also - as far as simple... I made a staff_email.php file that allows staff to see (obviously, re-used my IP Banning code... LOL)

<?
session_start();
include "sglobals.php";

if($ir[user_level] != 2){
echo "You are not an administrator and should not be trying to access this file.

Logged.";
stafflog_add("<font color=\"red\">Attempted to access email ban (not admin)</font>");
$h->endpage();
exit;
}

if(!isset($_POST[submit])){
banform();
$h->endpage();
exit;
}
else
{
ban_ip();
$h->endpage();
exit;

}

function ban_ip(){
global $db, $ir, $h;

$reason = mysql_real_escape_string($_POST[ban_reason]);
$address = mysql_real_escape_string($_POST[address]);

$db->query("INSERT INTO blacklist_domains (bl_text, bl_reason, bl_date, bl_userid) VALUES ('$address', '$reason', unix_timestamp(), $ir[userid])");

echo "You have banned the domain:  $address for $reason.

This has been logged.";

stafflog_add("Banned domain: $address");
echo "<hr>";

banform();
$h->endpage();
exit;

}


function banform(){
global $db, $ir, $h;

$ipq = "SELECT * FROM blacklist_domains WHERE bl_text = '$_GET[address]'";
$ips = $db->query($ipq);

if($db->num_rows($ips) > 0){
	echo "<font color=\"red\">This email is already banned\"</font>
";

}

require("class/email_validation.php");

$validator=new email_validation_class;

if(!function_exists("GetMXRR"))
{
	$_NAMESERVERS=array();
	include("getmxrr.php");

		echo "<font color=\"yellow\">It was not possible to determine if [b]$email[/b] is a valid address.</font>\n";
	else

	echo "<H2>Access this page using a URL like: $site?email=<A HREF=\"[email protected]\"><TT>[email protected]</TT></A></H2>\n";
}




list($username, $domain)=split('@',$_GET[address]); 

echo '

Re: Awesome 1st step to email validation.

its a nice modification some people may think it it really good but i think it isn't because 100 game users about 70 will have msn and the others that dont they will not be able to join which isnm't really fair and some dont like joining games that have email validation. :|

Re: Awesome 1st step to email validation.

Surely an easier and much quicker way to do this is to send an email to the user with a link/code?
