Create a simple user profile system

By Sidharth Patnaik -
This post guides you to create you own simple user profile system. Using this system, your users can register and sign in. The complete system is based of PHP and MYSQL. This system contains mainly 3 files, firstly the config.php, secondly the index.php and lastly the profile.php.  After uploading the files to your web server, first edit the details of the config.php file, namely the database user,name and password. The run in on the web browser, just like http://www.xyz.com/config.php/ now you are just good to go. Your users can access the system by just going to your url. i.e. http://www.xyz.com/.

 Demo

The Homepage of the System, showing both sign in and sign up buttons.


The Profile Page of the System, Showing the username and the last login details.



PHPMyAdmin panel showing the data entered in the database.

Lets Create the config.php file.

<?php
$dbhost = 'localhost';// Database Host.
$dbuser = 'sid';// Database User.
$dbpass = 'sp123';// User's Password.
$dbname = 'sample'; // Database Name
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(!$conn)
{
	die('Could not connect: ' . mysql_error());
}
$sql='CREATE TABLE USER ('.
	 'username VARCHAR(20)  NOT NULL,'.
	 'password VARCHAR(20)  NOT NULL,'.
	 'primary key(username))';
mysql_select_db($dbname);
$retval=mysql_query($sql,$conn);
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
  die('Could not create table: ' . mysql_error());
}
echo "Table student created successfully<br>";
?>

Lets Create the index.php file.
<?php
$dbhost = 'localhost';// Database Host.
$dbuser = 'sid';// Database User.
$dbpass = 'sp123';// User's Password.
$dbname = 'sample';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
	die('Could not connect: ' . mysql_error());
}
if(isset($_POST['in']))
{
	$sql = 'SELECT username, password from USER where username=\''.$_POST['name'].'\'';
	mysql_select_db($dbname);
	$retval = mysql_query( $sql, $conn );
	if(! $retval )
	{
		echo 'Invalid Username Entered, Please Check Again';
	}
	$row = mysql_fetch_row($retval);
	//echo $row[0].' '.$row[1];
	if($_POST['pass']==$row[1])
	{
		echo 'Logging you please wait !';
		session_start();
		$_SESSION['user'] = $_POST['name'];
		$_SESSION['time'] = time();
		?>
		<meta http-equiv="refresh" content="3;URL=profile.php" />
		<?php
	}
	else
	{
		echo 'Invalid Username Entered, Please Check Again';
	}
}
else if (isset($_POST['up']))
{
	$sql = "INSERT INTO user ".
       "VALUES('".$_POST['name']."','".$_POST['pass']."')";
	mysql_select_db($dbname);
	$retval = mysql_query( $sql, $conn );
	if(! $retval )
	{
		die('Could not get data: ' . mysql_error());
	}
	echo 'Logging you please wait !';
		session_start();
		$_SESSION['user'] = $_POST['name'];
		$_SESSION['time'] = time();
		?>
		<meta http-equiv="refresh" content="3;URL=profile.php" />
		<?php
}
?>

Non Restoring Division Algorithm Implementation in C

By Sidharth Patnaik -

This  is a Dynamic program for the implementation of the NON RESTORING Division Algorithm in C Language. Non Restoring Division uses Left Shift Operations, Twos' Compliment and Binary Addition. Screenshots[Demo] The Code #include<stdio.h> #include<malloc.h> int *a,*q,*m,*mc,*c,n,d; int powr(int x,int y) { int s=1,i; for(i=0;i<y;i++) s=s*x; return s; } void print(int arr[],int n) { int i; for(i=0;i<n;i++) printf("%d ",arr[i]); } void bin(int n, int arr[]){ int r, i = 0; do{ r = n % 2; n /= 2; arr[i] = r; i++; }while(n > 0); } void set(int array[], int x){ int i,tmp[20]={0}; for(i = x -1; i >=0; i--) tmp[x-1-i]=array[i]; for(i=0;i<x;i++) array[i]=tmp[i]; } int len(int x) { int i=0; while(powr(2,i)<=x) i++; return ++i; } void addBinary(int a1[], int a2[]) { int bi[2]={0},ca[20]={0}; int t=len(n),tmp=0; int *su=(int*)malloc(sizeof(int)*len(n)); while(t...

This is an implementation of the Bit Stuffing popularly used in data communication, also known as one of the concepts of Framing data bits. To know more please  click here. Sample Output: This is a sample output with data binary data entered as 11001111110. Program Code: import java.util.*; public class BitStuffing { public static void main(String[] args) { System.out.print("Enter the Binary message: "); Scanner sn=new Scanner(System.in); String data = sn.nextLine(); String res = new String(); String out=new String(); int counter = 0; for(int i=0;i<data.length();i++) { if (data.charAt(i)!='1' && data.charAt(i)!='0') { System.out.println("Enter only Binary values!!!"); return; } ...

Hackerrank Modified Kaprekar Numbers Solution

By Sidharth Patnaik -
Image
This is the solution to the Modified Kaprekar Numbers found in the implementation section of the algorithm domain in Hackerrank. A modified Kaprekar number is a positive whole number n with d digits, such that when we split its square into two pieces - a right hand piece r with d digits and a left hand piece l that contains the remaining d or d−1 digits, the sum of the pieces is equal to the original number (i.e. l + r = n) . Screenshot The Code def sendKap(x,s): y=x*x y=str(y) s1=y[:len(y)/2:] s2=y[len(y)/2::] s3=int(s1)+int(s2) if(s3==x): s.append(str(x)) st=input() en=input() s=[] for i in range(st,en+1): if(i>9): sendKap(i,s) elif(i==1): s.append(str(i)) elif(i==9): s.append(str(i)) if(len(s)==0): print 'INVALID RANGE' else: print ' '.join(s) Got any problems feel free to comment them here !
