3. Create registration form in HTML

                              After finished database and table creation, you need to create front end design which can be viewed by users. ie, client side script. Using below HTML code to create registration form in HTML.

<form action="#" method="post">
      <table id="tbl" align="center">
       <tr><td>Name:</td><td><input type="text" name="name" id="name"></td></tr>

    padding: 20px 10px;
    box-shadow: 1px 2px 1px #8FBF73;
    border-radius: 10px;
width:520px;
 }
 #name, #password, #mail {
    width: 250px;
    margin-bottom: 15px;

color:white;
}
#er {

$(document).ready(function() {
$('#submit').click(function() {
var name=document.getElementById('name').value;
var password=document.getElementById('password').value;
var mail=document.getElementById('mail').value;
var chk = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if(name=='')
{
 $('#er').html('Enter your name');
 return false;
}
if(password=='')
{
 $('#er').html('Enter your password');
 return false;
}
if(mail=='')
{
 $('#er').html('Enter your mail');
 return false;
}
if(!chk.test(mail))
{
 $('#er').html('Enter valid email');
 return false;
}
});

});

6. Connect Mysql database using PHP

                                     Then you need to write server side script to store values into database. First you make connection to Mysql database to store user values using PHP. Visit How to connect Mysql database using PHP. Add below PHP codes

  mysql_connect('localhost','root','') or die(mysql_error());
  mysql_select_db('new') or die(mysql_error());

7. Add PHP code for store values into database

                                     Here is the PHP code for insert user data into Mysql database. This is the code for avoid duplicate entries in table. visit How to avoid duplicate values storing in Mysql table while inserting using PHP. 

  $name=$_POST['name'];
  $password=$_POST['password'];
  $mail=$_POST['mail'];
  $q=mysql_query("select * from login where name='".$name."' or mail='".$mail."' ") or die(mysql_error());
  $n=mysql_fetch_row($q);
  if($n>0)
  {
   $er='The username name '.$name.' or mail '.$mail.' is already present in our database';
  }
  else
  {
   $insert=mysql_query("insert into login values('".$name."','".$password."','".$mail."')") or die(mysql_error());
   if($insert)
   {
    $er='Values are registered successfully';
   }
   else
   {
    $er='Values are not registered';
   }

  }

8. PHP script for register values into Mysql database

                                        Now you combine all above codes to single PHP file. Then you'll get code like below one. visit How to insert values into Mysql database using PHP.

Login validation using php and mysql

                      Everybody should see the login pages in most of websites. You should have doubt about this login form, how they validate username and password. There is nothing, just only 2 steps as follows as for login validation using php.
                      1. You enter username and password already registered which is stored in mysql database.
                      2. After you submit a button to login, it check the database values whether the username and password is correct or not using php and mysql query. The mysql query for select a values from mysql database as like this:
             
             ie, SELECT * FROM table_name WHERE name='username' and password='password' 

If it return values correctly, then you can login. Otherwise it give error message.

Simple login validation using php and mysql: 

                      Lets see how to validate the username and password using php.

                      1. First you create table using mysql query like this:

           CREATE TABLE login(name varchar(30), password varchar(30), PRIMARY KEY(name))

Now the table 'login' is created. The field 'name' is primary key. Because the username must be unique.

                      2. Then insert values into table using  mysql query like this:

           INSERT INTO login VALUES('guru','guru') 

Now the table look like this:

                       3. The php script for login validation as follows as:
login.php:

<html>
<head>
<style type="text/css">
 input{
 border:1px solid olive;
 border-radius:5px;
 }
 h1{
  color:darkgreen;
  font-size:22px;
  text-align:center;
 }
</style>
</head>
<body>
<h1>Login<h1>
<form action='#' method='post'>
<table cellspacing='5' align='center'>
<tr><td>User name:</td><td><input type='text' name='name'/></td></tr>
<tr><td>Password:</td><td><input type='password' name='pwd'/></td></tr>
<tr><td></td><td><input type='submit' name='submit' value='Submit'/></td></tr>
</table>

</form>
<?php
session_start();
if(isset($_POST['submit']))
{
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $name=$_POST['name'];
 $pwd=$_POST['pwd'];
 if($name!=''&&$pwd!='')
 {
   $query=mysql_query("select * from login where name='".$name."' and password='".$pwd."'") or die(mysql_error());
   $res=mysql_fetch_row($query);
   if($res)
   {
    $_SESSION['name']=$name;
    header('location:welcome.php');
   }
   else
   {
    echo'You entered username or password is incorrect';
   }
 }
 else
 {
  echo'Enter both username and password';
 }
}
?>
</body>
</html>

        Where,
                if(isset($_POST['submit']){}    means run after submit a results.
                if($name!=''&&$pwd!=''){}   means if either username or password is empty, it give message like as 'Enter both username and password'.
                mysql_query("select * from login where name='".$name."' and password='".$pwd."'  ")      select the values if the username and password is present.
                $res=mysql_fetch_row($query) return row as numeric array.
You don't know about mysql_fetch_row, then visit mysql-fetch-row in mysql.
               if($res){} validate the result. If it is correct, then your name is stored in session variable and also you'll navigate to 'welcome.php' page. Otherwise you'll get 'You entered username or password is incorrect' message. You want to visit Session in php.
              When you run the above file, it should be like this:

             
               The php script for welcome page:

 welcome.php:

<?php    
         session_start();
         $name=$_SESSION['name'];    
         echo'welcome :'. $name.'<br>';
         echo'<a href="signout.php">Signout</a>';
?>

      

             Now you enter username and password  'guru' and 'guru', you will navigate to 'welcome.php' page and get output like this:

                   welcome: guru
                   Signout

 If it is wrong, then you can't login.

Signout in php:              

            When you click the signout.php, it destroy the session and return back to login page. The php script for signout page:
signout.php:

<?php    
         session_start();
         session_destroy();
         header('location:login.php');
?>

                session_destroy is used to destroy the session variable in php.

                              SELECT table_name.column_name FROM table_name

Copy data from one database to another in mysql:

                       Consider following example. You've two databases named with db1 and db2. Each database have a table. Table1 is presented in db1 and Table2 is present in db2.

The Table1 in db1 is look like this:

The Table2 in db2 look like this:

Now we copy data from database db1 to db2. The mysql query is:

                     
                     INSERT INTO db2.Table2(name,image)

                              SELECT Table1.name, Table2.name FROM Table1
