  1. Thanks for the reply but there is another problem.

     

     

    Tried it already

    Show an error.

     

     

    Parse error: parse error, unexpected $end in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\user_conn.php on line 61

     

    The line is 61 is the </html> tag.

     

    here's the code.

     

    <html xmlns="http://www.w3.org/1999/xhtml">

    <head>

    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

    <title>Log In</title>

    <link href="user_main.css" rel="stylesheet" type="text/css" />

    <?php

    $username = $_POST['username'];

    $password = $_POST['password'];

    $password = trim($password);

     

    if (!$username && !$password){

     

      echo 'Enter you username followed by your password';

      exit;

    }

     

    $mysqli = new mysqli("localhost", "user", "dbpassword", "db");

     

    /* check connection */

    if (mysqli_connect_errno()) {

      printf("Connect failed: %s\n", mysqli_connect_error());

      exit();

    }

     

    $query = "SELECT username, password FROM users ORDER by username = '$username'

            and password = '$password' ";

     

    $result = mysqli_query($mysqli, $query);

    if (!$result)

    {

      echo 'Cannot connect sorry';

      exit;

    }

    else

    {

     

      if(mysqli_num_rows($result) == 0){

      echo "Username or password is incorrect";

      die();

      }else {

    /* fetch associative array */

      while ($row = mysqli_fetch_row($result))

     

        {

          printf ( $row[0], $row[1]);

     

      }

     

      /* free result set */

      mysqli_free_result($result);

      printf ("connection success");

    }

     

    $mysqli->close();

    ?>

    </head>

  2. Hi guys..

     

    I have a little problem on my codes.

     

    I've tested the connection of MySql and PHP that's fine.

     

    Now my problem is the authentication of it.

     

    When ever I've entered a not valid username and password it will connect to my other page.

     

    Did I miss something?

     

    What's seem the problem here?

    Here's the code:

     

    <?php

     

     

    $username = $_POST['username'];

    $password = $_POST['password'];

    $password = trim($password);

     

    if (!$username && !$password){

     

      echo 'Enter you username followed by your password';

      exit;

    }

     

    $mysqli = new mysqli("localhost", "my_user", "mypassword", "my_db");

     

    /* check connection */

    if (mysqli_connect_errno()) {

      printf("Connect failed: %s\n", mysqli_connect_error());

      exit();

    }

     

     

    $query = "SELECT username, password FROM users ORDER by username = '$username'

            and password = '$password' ";

     

    $result = mysqli_query($mysqli, $query);

    if (!$result)

    {

     

      echo 'Cannot connect sorry';

      exit;

    }

    else

    {

     

      /* fetch associative array */

      while ($row = mysqli_fetch_row($result))

     

        {

          printf ( $row[0], $row[1]);

     

      }

     

      /* free result set */

      mysqli_free_result($result);

      printf ("connection success");

    }

     

    $mysqli->close();

    ?>

     

    Help!!

     

    Thanks guys.

  3. Hi guys.

    In computer science we are using discrete math right?

    I want know what is the role of discrete math in computing.

    I mean in our everyday lives, I'd like to see the importance of it.

    I want to see the theories in discrete math is used in the field programming / software developing, games, web developing, business, or operating system stuff like that.

    Cos I don't see it. Especially if you are living where outsourcing is in rapid growth.

    I've asked my professor on this one he will just answer "is included to my course a pre-requisite of automata" or "in some technology today"

    I don't want a general answer, I want a specific answer on this.


    Thanks guys.
