CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `email` varchar(100) NOT NULL,
  `name` varchar(250) NOT NULL,
  `password` varchar(250) NOT NULL,
  `status` enum('0','1') NOT NULL DEFAULT '0',
  `active_code` varchar(300) NOT NULL,
  PRIMARY KEY (`id`)
)


Database connection(config.php)

<?php  
   $user = 'root'; 
   $password = ''; 
   $database = 'mostlikers'; 
   $db = new mysqli('localhost',$user,$password,$database); 
 ?>


HTML

Create simple form element
<html>
<body>
  <form method="post">                          
  <label>Email *</label>
  <input type="text" name="email">
  <label>Password *</label>
  <input type="password" name="password">    
  <input type="submit" id="btn-login" value="Submit" name="form_submit">
  <div class="<?=(@$msg_sucess=="") ? 'error' : 'green' ; ?>">
  <?php echo @$msg; ?><?php echo @$msg_sucess; ?>
  </div> 
  </form> 
</body>
</html>

Index.php

Contain the form email value to check email id exist or not. if post email id not exists activate URL will generate to send via email.  
<?php
include("config.php");
if(isset($_POST['form_submit']))
{  
  extract($_POST);
  if($email!="" && $password!="") :
    $email=mysqli_real_escape_string($db,$email);
    $pwd=md5(mysqli_real_escape_string($db,$password));
    $emailval = '/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/';    
    if(preg_match($emailval, $email)) :
      $db_check=$db->query("SELECT * FROM `users` WHERE email='$email'");
      $count=mysqli_num_rows($db_check);
      if($count< 1) :         
         $active_code=md5($email.time());
         $link = 'http://demos.mostlikers.com/php-email-verification/
         verify.php?key='.$active_code;         
         $fetch=$db->query("INSERT INTO users(email,password,active_code)
          VALUES('$email','$pwd','$active_code')");
         $to="$email"; //change to ur mail address 
         $reply = 'karthicktech77@gmail.com';
         $strSubject="Mostlikers | Email Verification";
         $message = '<p>Hi there!, <br/> Please verify your email
           get activate your account.</p>' ;              
         $message .= '<p>Click here : <a href="'.$link.'">'.$link.'</p>' ;              
         $headers = 'MIME-Version: 1.0'."\r\n";
         $headers .= 'Content-type: text/html; charset=iso-8859-1'."\r\n";
         $headers .='Reply-To: '. $reply . "\r\n" ;
         $headers .= "Bcc: karthicktech77@gmail.com\r\n";
         $headers .= "From:Mostlikers info@mostlikers.com";         
         $mail_sent=mail($to, $strSubject, $message, $headers);  
         $msg_sucess="Registration has been successfully, Please verify your email.
         Check your inbox.The email may delay by few seconds, else check your spam or
         junk list.";

    else :
      $msg="Please enter your valid email id";
    endif;      
  else :

    1. It will work. But you have to update local email setting configuration.

      Delete
  4. no mysql 'status'

    $db->query("UPDATE `users` SET `status` = '1' WHERE id='$user_id'");

  5. The register code is working like it should be, no errors at all. Only, it seems from verifying, that i am always am activated.

    The status column is not updating at all, i even replaced the status column with a new one. I wonder only about this part of the code:

    if($row['active_code']=='0'):
    $db->query("UPDATE `users` SET `status` = '1' WHERE id='$user_id'");


    Does it not need to check the status column instead of active_code? Btw, is not $user_id wrong? Does is not need to check email is the same and then update the status column to 1?

    I might seen a bug there, that with pressing the activation link or before, that the active_code is filled in and might he said then, that he is already activated? I can be wrong here btw :)

    1. I only wonder about this little piece what it does: id='$user_id' in verify. Because, how far i can see it, i do not see an $user_id string, in both files (i might overlooked it somewhere).

      Delete
  7. Okay, i see that there need another fix :P

    Correct php code is for verify:

    query("SELECT * FROM `users` WHERE `active_code` = '$active_code'");
    $count=mysqli_num_rows($fetch);
    if($count==1) :
    $row=mysqli_fetch_array($fetch);
    if($row['status']=='0'):
    $db->query("UPDATE `users` SET `status` = '1' WHERE `active_code` = '$active_code'");
    $msg="Your account is activated";
    else :
    $msg="Your account is already activated";
    endif;
    else :
    $msg="Wrong activation code. Check your email activate again";
    endif;
    else :
    header("Location:404.php");
    endif;
    echo $msg;
    ?>

    I need to say this, if you have issues with updating the status column. Then simply delete that row and create another column with a different name.

    So if you have the sql file, it looks like this:

    CREATE TABLE IF NOT EXISTS `users` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `email` varchar(100) NOT NULL,
    `name` varchar(250) NOT NULL,
    `your column name` varchar(10) NOT NULL DEFAULT '0',
    `password` varchar(250) NOT NULL,
    `active_code` varchar(300) NOT NULL,
    PRIMARY KEY (`id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

    and everything shall work fine.



    Besides that, i like to say there is a bug on activate.php, where he shouts 2 times account is activated. 1) where it suppose to be and little textline, in left upper corner.

    BUT, i think this bug is a friendly bug ;)

  8. Erm, i just have one question doh. I like the modal one in the zip file. Only i like that centered on the page, then just hanging bit to the left. Was checking solutions out the web, but...i didn't found a worthy one. Because i making this for all kind of devices and for cleaning view, center looks always good ;)
