PHP - Password Generation

Hello PhP Freaks forum
In the past weeks ive been trying to make a website, where you can register. Everything seems to work except my cherished Change password feature. Everytime you try to change the password, it just resets it to nothing.

Here is the code below.

<?php
         if(isset($_SESSION['username']))
         {
            $username = $_SESSION['username'];
            $lastname = $_SESSION['lastname'];
            $firstname = $_SESSION['firstname'];
            $email = $_SESSION['email'];
               
            echo "
            
               <h4>Options for:</h4> &nbsp; $username
               <br />
               <br />
               First name: &nbsp; $firstname
            
               <br />Last name: &nbsp; $lastname       
   
   <br /><br /><h3>Want to change your password:</h3><br />
   
      <form action='?do=option' method='post'>
   
      Old password <input type='password' placeholder='Has to be between 5-15 digits' name='password' size='30' value='' /><br />
                  <br />
      New Password<input type='password' placeholder='Has to be between 5-15 digits' name='newpass' size='30' value='' /><br />
                  <br />
      Confirm new password <input type='password' placeholder='Has to be between 5-15 digits' name='passconf' size='30' value='' /><br />
                  
      <center></div><input type='submit' value='Submit'/></center></form>";   
      
            
         }else{
            echo 'Please login to view your options!';
         }
      
      $password = $_REQUEST['password'];
      $pass_conf = $_REQUEST['newpass'];
      $email = $_REQUEST['passconf'];
      
      $connect = mysql_connect("Host", "User", "Password");
      if(!$connect){
      die(mysql_error());
      }
      
      //Selecting database
      $select_db = mysql_select_db("My Database", $connect);
      if(!$select_db){
      die(mysql_error());
      }
      
      //Find if entered data is correct
      
      $result = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'");
      $row = mysql_fetch_array($result);
      $id = $row['id'];

            
         mysql_query("UPDATE users SET password='$newpass' WHERE username='$user'")
      
      ?>          

And i do know that i dont have a

if(Empty($newpass)){
Die(Please fill out the new password)                                                 
}

Or any security on the others, but the problem just seems that it resets the password into nothing

Hope i can get this fixed

Best Regards

Hi guys, this is very urgent. Can anyone help me out.....

I want to generate reports using php and MySQL. I have one table which includes customer_id, full_name, name_with_initials, address, contact_number and gender fields. I want to print the details of all the records of the table. It should be good if results will come on a PDF format.

Thanks,
