Can this code be chopped up to fit my needs?

[Modernvox]

Hi Guyz (& Girlz)

 

I have this email verification code I would like to use. I am wondering if it can be edited in such a way:

 

I want the user to be able to post an ad on my site quickly without having to sign up. At the same token I want to make them activate the posting by clicking on a link by email.

 

I only want to check the md5 hash, not there user name and all that.

 

I also want to ban Gmail users(I understand some honest folks use this service, but i would rather not deal with all the spam from other countries.

 

Any help much appreciated as always.

 

<?
include('config.php');

// Passkey that got from link
$passkey=$_GET['passkey'];

$tbl_name1="temp_members_db";

// Retrieve data from table where row that match this passkey
$sql1="SELECT * FROM $tbl_name1 WHERE confirm_code ='$passkey'";
$result1=mysql_query($sql1);

// If successfully queried
if($result1){

// Count how many row has this passkey
$count=mysql_num_rows($result1);

// if found this passkey in our database, retrieve data from table "temp_members_db"
if($count==1){

$rows=mysql_fetch_array($result1);
$name=$rows['name'];
$email=$rows['email'];
$password=$rows['password'];
$country=$rows['country'];

$tbl_name2="registered_members";

// Insert data that retrieves from "temp_members_db" into table "registered_members"
$sql2="INSERT INTO $tbl_name2(name, email, password, country)VALUES('$name', '$email', '$password', '$country')";
$result2=mysql_query($sql2);
}

// if not found passkey, display message "Wrong Confirmation code"
else {
echo "Wrong Confirmation code";
}

// if successfully moved data from table"temp_members_db" to table "registered_members" displays message "Your account has been activated" and don't forget to delete confirmation code from table "temp_members_db"
if($result2){

echo "Your account has been activated";

// Delete information of this user from table "temp_members_db" that has this passkey
$sql3="DELETE FROM $tbl_name1 WHERE confirm_code = '$passkey'";
$result3=mysql_query($sql3);

}

}
?>

config.php - config your database

<?

$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name=""; // Database name


//Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect to server");
mysql_select_db("$db_name")or die("cannot select DB");

?>
