The Module Manager will display the screen where you could add and edit Joomla Modules such as Menu Module, Banner Module, Login Module and Breadcrumbs etc. In Joomla, Modules are used to display content and/or media around the main content.
There are lots of module has been installed with default template in joomla software, which you could use in your default template or customize template at specified position. But in any case if you want to make your own customize module to perform any specific task then you have to perform some following steps.
1. You have to create two files: PHP file and XML file for module
2. Upload zip folder of module files
Steps 1:Creating PHP and XML file
Before creating these files you have to follow up a certain formatting.
First of all create a directory with name mod_customizelogin (here I am creating customize login form). Now, you have to create two file with mod_customizelogin.php and mod_customizelogin.xml name and put these files within mod_customizelogin directory.
Here, I am creating customize login form. To create customize login form, write down following codes.
‘mod_customizelogin.php’ Code:
<?php
global $error, $count,$myusername ;
include("mod_Config.php");
if($_SERVER["REQUEST_METHOD"] == "POST")
{
// username and password sent from Form
// Store username and password from From
$myusername= ($_POST['username']);
$mypassword=($_POST['password']);
if($myusername == null || $mypassword == null)
{
$error ="Plaese! fill all enteries";
}
else
{
// Check username and password in database table
$sql="SELECT id FROM dbmyjoomla.lolt9_users WHERE username='$myusername' and password='$mypassword'";
// Create qurey in mysql
$result=mysql_query($sql);
// fetch specified record
$row=mysql_fetch_array($result);
$active=$row['active'];
//Count number of rows in result
$count=mysql_num_rows($result);
//If result matched $myusername and $mypassword, table row must be 1 row
if($count==1)
{
session_register("myusername");
$_SESSION['login_user']=$myusername;
header("location:http://localhost/Joomla17/");
}
else
{
$error ="Your UserName or Password is invalid";
}
}
}
?>
<?php
echo '<head>';
echo '<link href="css/login.css" type="text/css" rel="stylesheet"></link>';
echo '</head>';
?>
<form action="mod_customlogin.php" method="post">
<div id="login">
<div class="lflogo"> <img src="Images/Clogo.png"></img></div>
<table id="tblLogin">
<tr>
<td>
<label>UserName :</label>
</td>
<td>
<input type="text" name="username"/>
</td>
</tr>
<tr>
<td>
<label>Password :</label>
</td>
<td>
<input type="password" name="password"/>
</td>
</tr>
<tr><td class="button">
<input id="btnTd" type="submit" value=" Login " onclick="return fvalidation()"/>
</td>
<td><input type="checkbox"></input> <label>Remember Me</label> </td>
</tr>
</table>
<div id="footer">
<table>
<tr>
<td> <a href=""> Forgot Password?</a> </td>
<td><a href="">Create An Account!</a></td>
</tr>
</table>
</div>
<div id="msgError"> <label><?php echo $error; ?></label> </div>
</div>
</form>
‘mod_Config.php’ Code:
<?php
/* localhost server information */
$mysql_hostname = "localhost"; /*localhost name */
$mysql_user = "root";
$mysql_password = "root";
$mysql_database = "dbmyjoomla"; /* Your database name */
// creating connection with database
$con = mysql_connect($mysql_hostname, $mysql_user, $mysql_password)
or die("Opps connection cannot be establish");
// select database from mysql
mysql_select_db($mysql_database, $con) or die("Opps database could not be connected");
?>
‘mod_CheckSession.php’ Code:
<?php
// include database config file
include('mod_Config.php');
//start session
session_start();
// assign login user name
$user_check=$_SESSION['login_user'];
// select username from joomla table
$ses_sql=mysql_query("select username from dbmyjoomla.lolt9_users where username='$user_check' ");
// retrieve selected row from database table
$row=mysql_fetch_array($ses_sql);
// assign login username
$login_session=$row['username'];
// check person in session
if(!isset($login_session))
{
header("Location: login.php"); // redirect into login page if session is timeout
}
?>
‘mod_logout.php’ Code:
<?php
session_start();
// if session is time out then session will be destryed and page redirect to login page
if(session_destroy())
{
header("Location: login.php"); // page redirect into login page
}
?>
‘mod_customlogin.xml’ Code:
‘mod_customlogin.xml’ uses in joomla software like an installer file for module. So you have to careful about this file at creating time.
Let’s take a look of ‘mod_customlogin.xml’ file code.
‘mod_customlogin.xml’ code:
<?xml version="1.0" ?>
<!DOCTYPE install PUBLIC "-//Joomla! 1.7//DTD module 1.0//EN" "http://dev.joomla.org/xml/1.5/module-install.dtd">
<install version="1.7" type="module">
<name>Custom Login Form</name>

Now your first step has been completed and proceeds for second step.
