How to make admin page with database

#0: Strategy Used behind the Login System:

Here we shall use 5 files for making the whole system.

• config.php: The main file for holding the information related to the admin MySQL table. We shall discuss in brief how to create the table. For information do check the MySQL posts.
• admin.php: For administrative functions. It will redirect to login.php if not authorized already;
• login.php: A webpage for displaying form of login. It will submit the form to check_login.phpwhere it will be processed further;
• check_login.php: A PHP script to check the login details from the MySQL Table. If successfully matched, then it will register the Session, else will redirect back to the login.php file with error message;
• logout.php: It will delete the session, and will redirect back to login.php file with success message;

#1: Setting up the MySQL Table:

We shall use a MySQL table like this for storing administrator information:

id	user_name	user_pass
1	admin	admin
2	swashata	swashata

Basically we shall encrypt the password inside the table. Just for the demonstration I have showed the passwords above…

Now create a Database and inside it create a table login_admin with the following MySQL query command:

?

1 2 3 4 5 6 7

CREATE TABLE login_admin ( id INT NOT NULL AUTO_INCREMENT, user_name VARCHAR(100), user_pass VARCHAR(200), PRIMARY KEY (id) )

Now insert the two user information inside the table with the following command:

INSERT INTO login_admin (user_name, user_pass)

VALUES

(

‘swashata’, SHA(‘swashata’)

)

INSERT INTO login_admin (user_name, user_pass)

VALUES

(

‘admin’, SHA(‘admin’)

)




Now your MySQL table is ready for use!




#2: Setting up the config.php file:

As mentioned before, it just contains all the necessary MySQL Database connection information. Here is the code for this file:




<?php

/**********************************************************************

 *Contains all the basic Configuration

 *dbHost = Host of your MySQL DataBase Server... Usually it is localhost

 *dbUser = Username of your DataBase

 *dbPass = Password of your DataBase

 *dbName = Name of your DataBase

 **********************************************************************/

$dbHost = 'localhost';

$dbUser = 'Data Base User Name';

$dbPass = 'Data Base Password';

$dbName = 'Data Base Name';

$dbC = mysqli_connect($dbHost, $dbUser, $dbPass, $dbName)

        or die('Error Connecting to MySQL DataBase');

?>

Just save this file with the above codes.
