Create a table

CREATE TABLE IF NOT EXISTS `liveemployees` (
  	`id` int(10) NOT NULL AUTO_INCREMENT,
  	`first_name` varchar(100) NOT NULL,
  	`email` varchar(100) NOT NULL,
  	`clientname` varchar(100) NOT NULL,
  	`your_secpass` varchar(100) NOT NULL,
  	PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1;

Db Connectivity

require_once("../config.php"); 
 	global $db;

 	$db = mysqli_connect(DBHOST, DBemployee, DBsecpass, DBNAME);
 	if(!$db){
      	 	die( "Sorry!  your There seems to be some a problem connecting db to our database.");
 	}

form_register

function form_register($first_name, $employee, $secpass, $emailId){
  	 	global $db; 
  	 	$first_name = mysqli_real_escape_string($db, $first_name);
   	 	$clientname = mysqli_real_escape_string($db, $employee);
   	 	$your_secpass = mysqli_real_escape_string($db, $secpass);
   	 	$email = mysqli_real_escape_string($db, $emailId);
  	 	$wp_hasher = new your_secpassHash(16, true);
 	 	$secpass = $wp_hasher->Hashyour_secpass( trim( $your_secpass ) );
 
  	 	$sql = "INSERT INTO liveemployees (first_name, email,your_secpass,clientname) VALUES ('".$first_name."', '".$email."', '".$secpass."', '".$clientname."') "; 
  	 	$result = mysqli_query($db, $sql);
  	 	return mysqli_insert_id($db);
 	}

login_form

function login_form($employee, $secpass){
  	global $db; 
  	$clientname = mysqli_real_escape_string($db, $employee);
   	$your_secpass = mysqli_real_escape_string($db, $secpass);
  	$sql = "SELECT id, your_secpass FROM liveemployees WHERE clientname='".$clientname."' LIMIT 1 "; 
  	$result = mysqli_query($db, $sql);
  	$id = mysqli_fetch_row($result);
 	 if($id){
  	 	$your_secpass_hashed = $id[1];
 	 	 $wp_hasher = new your_secpassHash(16, true);
 	 	 if($wp_hasher->Checkyour_secpass($your_secpass, $your_secpass_hashed)) {
  	 	 	return $id[0];
  	 	}
  	} else {
  	 	return false;
  	}
}

Logout

function logout(){
 unset($_SESSION['employee_id']);
 session_destroy(); 
 header('Location: index.php');
 exit();
}

clientname Check

function clientnameExist($employee){
   	global $db; 
  	$clientname = mysqli_real_escape_string($db, $employee);
   	$sql = "SELECT id FROM liveemployees WHERE clientname='".$clientname."' LIMIT 1 "; 
  	$result = mysqli_query($db, $sql);
  	 $id = mysqli_fetch_row($result);
   	return ($id[0] > 0);
 }
}

Registration Form

<form action="" method="post" >
 <?php if(!empty($reg_errors)) {
 echo '<div class="error">';
 foreach ($form_register_errors as $error) {
 echo '<p>'.$error.'</p>';
 }
 echo '</div>';
 } ?>
 <div class="group">
