Project Structures

This is the project structures:

We have index.php, config.php at a root of the directory. There are two folder css and js which contain main.css, main.js and our jQuery files.

index.php – going to be our main PHP file to display a login form
config.php – going to be our database configuration file where we’ll add all database details like server, database name, database username and database password.
main.css – This is going to be our stylesheet for styling the form.
main.js – This contain the script of the project.
jQuery Files – The one is the main jQuery file and the other is for validation.

Create a PHP File:

First, create an index.php in the project folder and add the following code into it:

<?php

session_name('LoginForm');
@session_start();

error_reporting(0);
include("config.php");

?>

Create Database Config File:

First create a database:

Go to PHPMYADMIN and create a new database for the project. We had name a database as laraveltuts for this project.

Create a table with Fields:

As now you had created a database now its time to create a users table. Create a new table users in laraveltuts database.

After you create table add column as shown in the image:

Add User details to table:

Now it’s time to insert users into it. We had inserted a new record to the table.

Create a config.php file in the root directory of the project and add the following code:

<?php

/* Define MySQL connection details and database table name */
$SETTINGS["mysql_user"]='root';
$SETTINGS["mysql_pass"]='';
$SETTINGS["hostname"]='localhost';
$SETTINGS["mysql_database"]='laraveltuts';
$SETTINGS["USERS"] = 'users'; // this is the default table name that we used

/* Connect to MySQL */
$mysqli = new mysqli($SETTINGS["hostname"], $SETTINGS["mysql_user"], $SETTINGS["mysql_pass"],$SETTINGS["mysql_database"]);
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

Add the MySql Username, Password, Hostname and Table name.

Create JS:

Download the jQuery and jQuery Validation and add it to js folder.

Add the following style to js/main.js file.

var jQuery_1_8_2 = $.noConflict();
(function ($, undefined) {
	$(function () {
		var form = $('#login-form');
			
		if (form.length > 0) {
			form.validate({
			});
		}
		
	});
})(jQuery_1_8_2);
