User registration and login using stored procedure in PHP

by Anuj Kumar

Hello, friends in this tutorial we will learn user registration and login using PHP stored procedure.
File structure for this tutorial

config.php
index.php
check_availability.php
login.php
welcome.php
logout.php

Structure of SQL table tblregistration

CREATE TABLE `tblregistration` (
  `id` int(11) NOT NULL,
  `FullName` varchar(200) NOT NULL,
  `EmailId` varchar(200) NOT NULL,
  `Password` varchar(255) NOT NULL,
  `RegDate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

CREATE TABLE `tblregistration` (

`id` int(11) NOT NULL,

`FullName` varchar(200) NOT NULL,

`EmailId` varchar(200) NOT NULL,

`Password` varchar(255) NOT NULL,

`RegDate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP

) ENGINE=InnoDB DEFAULT CHARSET=latin1;

config.php

Create DB configuration file using MySQLi extension. Provide credential as per your configuration

<?php
$con = mysqli_connect("localhost","root","","storeprocedure");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>

<?php

$con = mysqli_connect("localhost","root","","storeprocedure");

// Check connection

if (mysqli_connect_errno())

{

echo "Failed to connect to MySQL: " . mysqli_connect_error();

}

index.php

Create an HTML form for user registration.

<form class="form-horizontal"  method="post">
  <fieldset>
    <div id="legend">
      <legend align="center" style="font-size: 35px;">Register</legend>
    </div>
    <div class="control-group">
      <!-- Fullname -->
      <label class="control-label"  for="fname">Full Name</label>
      <div class="controls">
        <input type="text" id="name" name="fname" placeholder="" class="input-xlarge" required>
      </div>
    </div>
    <div class="control-group">
      <!-- E-mail -->
      <label class="control-label" for="email">E-mail</label>
      <div class="controls">
        <input type="email" id="email" name="email" placeholder="" class="input-xlarge" onBlur="checkAvailability()"  required>
 <span id="user-availability-status" style="font-size:12px;"></span>
      </div>
    </div>
    <div class="control-group">
      <!-- Password-->
      <label class="control-label" for="password">Password</label>
      <div class="controls">
        <input type="password" id="password" name="password" placeholder="" class="input-xlarge" required>
      </div>
    </div>
<div class="control-group">
      <!-- Button -->
      <div class="controls">
        <input  class="btn btn-success" id="submit" type="submit" value='register' name="register">
      </div>
    </div>
 <div class="control-group">
      <div class="controls">
   <p class="message">Already registered. <a href="login.php">login here</a></p>
      </div>
    </div>
  </fieldset>
</form>

<legend align="center" style="font-size: 35px;">Register</legend>

</div>

</div>

</div>

<label class="control-label" for="password">Password</label>

</div>

</div>

<p class="message">Already registered. <a href="login.php">login here</a></p>

</div>

</fieldset>

</form>

Jquery / Ajax for user email availability

<script>
function checkAvailability() {
$("#loaderIcon").show();
jQuery.ajax({
url: "check_availability.php",
data:'emailid='+$("#email").val(),
type: "POST",
success:function(data){
$("#user-availability-status").html(data);
$("#loaderIcon").hide();
},
error:function (){}
});
}
</script>

function checkAvailability() {

$("#loaderIcon").show();

jQuery.ajax({

url: "check_availability.php",

data:'emailid='+$("#email").val(),

type: "POST",

success:function(data){

$("#user-availability-status").html(data);

$("#loaderIcon").hide();

error:function (){}

});

}

</script>

check_availability.php

In this page, we will check the user email availability. Create a store procedure with name check availability
Stored procedure code :

DELIMITER $
CREATE DEFINER=`root`@`localhost` PROCEDURE `checkavailbilty`(IN `email` VARCHAR(255))
    NO SQL
SELECT EmailId FROM tblregistration  WHERE EmailId=email$
DELIMITER ;

DELIMITER $

CREATE DEFINER=`root`@`localhost` PROCEDURE `checkavailbilty`(IN `email` VARCHAR(255))

NO SQL

SELECT EmailId FROM tblregistration WHERE EmailId=email$

DELIMITER ;

PHP Code for check_availability.php

<?php 
require_once("config.php");
if(!empty($_POST["emailid"])) {
$email= $_POST["emailid"]; 
$result =mysqli_query($con,"call checkavailbilty('$email')");
$count=mysqli_num_rows($result);
if($count>0)
{
echo "<span style='color:red'> Email already exists .</span>";
echo "<script>$('#submit').prop('disabled',true);</script>";
} else{ 
echo "<span style='color:green'> Email available for Registration .</span>";
echo "<script>$('#submit').prop('disabled',false);</script>";
}
}
?>

<?php

require_once("config.php");

if(!empty($_POST["emailid"])) {

$email= $_POST["emailid"];

$result =mysqli_query($con,"call checkavailbilty('$email')");

$count=mysqli_num_rows($result);

if($count>0)

{

echo "<span style='color:red'> Email already exists .</span>";

echo "<script>$('#submit').prop('disabled',true);</script>";

} else{

echo "<span style='color:green'> Email available for Registration .</span>";

echo "<script>$('#submit').prop('disabled',false);</script>";

}

Now create a store procedure for user registration.
Store procedure for user registration

DELIMITER $
CREATE DEFINER=`root`@`localhost` PROCEDURE `registration`(IN `fname` VARCHAR(200), IN `emailid` VARCHAR(200), IN `password` VARCHAR(255))
    NO SQL
insert into tblregistration(FullName,EmailId,Password) VALUES(fname,emailid,password)$
DELIMITER ;

DELIMITER $

CREATE DEFINER=`root`@`localhost` PROCEDURE `registration`(IN `fname` VARCHAR(200), IN `emailid` VARCHAR(200), IN `password` VARCHAR(255))

NO SQL

insert into tblregistration(FullName,EmailId,Password) VALUES(fname,emailid,password)$

DELIMITER ;

After creation of store procedure execute the store procedure.

<?php
include('config.php');
if(isset($_POST['register']))
{
 $fname=$_POST['fname'];
 $email=$_POST['email'];
 $password=md5($_POST['password']);
 // Excute the procedure
$query=mysqli_query($con,"call registration('$fname','$email','$password')");
if($query)
{
echo "<script>alert('Registration Successfull');</script>";
}
else
{
echo "<script>alert('Something went wrong. Please try again.');</script>";
}
}
?>

<?php

include('config.php');

if(isset($_POST['register']))

{

$fname=$_POST['fname'];

$email=$_POST['email'];

$password=md5($_POST['password']);

// Excute the procedure

$query=mysqli_query($con,"call registration('$fname','$email','$password')");

if($query)

{

echo "<script>alert('Registration Successfull');</script>";

}

else

{

echo "<script>alert('Something went wrong. Please try again.');</script>";

}

Here is the full code that we have written for registration (index.php):

<?php
include('config.php');
if(isset($_POST['register']))
{
 $fname=$_POST['fname'];
 $email=$_POST['email'];
 $password=md5($_POST['password']);
$query=mysqli_query($con,"call registration('$fname','$email','$password')");
if($query)
{
echo "<script>alert('Registration Successfull');</script>";
}
else
{
echo "<script>alert('Something went wrong. Please try again.');</script>";
}
}
?>

function checkAvailability() {

login .php

Create a login form user login.

 <div class="login-page">
  <div class="form">
    <form class="login-form" method="post">
      <input type="text" placeholder="Email id" name="useremail" required />

  </div>
</div>

<button type="submit" name="login">login</button>

<p class="message">Not registered? <a href="index.php">Create an account</a></p>

</form>

</div>

Now create a store procedure for login with name login.
Login store procedure :

 DELIMITER $
CREATE DEFINER=`root`@`localhost` PROCEDURE `login`(IN `useremail` VARCHAR(255), IN `password` VARCHAR(255))
    NO SQL
SELECT EmailId,Password from  tblregistration where EmailId=useremail and Password=password$
DELIMITER ;

DELIMITER $

CREATE DEFINER=`root`@`localhost` PROCEDURE `login`(IN `useremail` VARCHAR(255), IN `password` VARCHAR(255))

NO SQL

SELECT EmailId,Password from tblregistration where EmailId=useremail and Password=password$

DELIMITER ;

Now execute the login store procedure

<?php
session_start();
include('config.php');
if(isset($_POST['login']))
{
  $email=$_POST['useremail'];
  $password=md5($_POST['password']);
  $query=mysqli_query($con,"call login('$email','$password')");
$num=mysqli_fetch_array($query);
if($num>0)
{
$_SESSION['login']=$_POST['useremail'];
header("location:welcome.php");
}
else
{
$_SESSION['login']=$_POST['useremail'];
echo "<script>alert('Invalid  login details');</script>";
$extra="login.php";
}
}
?>

<?php

session_start();

include('config.php');

if(isset($_POST['login']))

{

$email=$_POST['useremail'];

$password=md5($_POST['password']);

$query=mysqli_query($con,"call login('$email','$password')");

$num=mysqli_fetch_array($query);

if($num>0)

{

$_SESSION['login']=$_POST['useremail'];

header("location:welcome.php");

}

else

{

$_SESSION['login']=$_POST['useremail'];

echo "<script>alert('Invalid login details');</script>";

$extra="login.php";

}

Here is the full code that we have written for login(login.php):
