CREATE TABLE tbl_auth_user (
user_id VARCHAR(10) NOT NULL,
user_password CHAR(32) NOT NULL,

PRIMARY KEY (user_id)
);

INSERT INTO tbl_auth_user (user_id, user_password) VALUES ('theadmin', PASSWORD('chumbawamba'));
INSERT INTO tbl_auth_user (user_id, user_password) VALUES ('webmaster', PASSWORD('webmistress'));


//Now that that is created I looked at the PHP code and this is what I have questions on.

<?php
// we must never forget to start the session
session_start();

$errorMessage = '';
if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) {
   include 'library/config.php';
   include 'library/opendb.php';

   $userId = $_POST['txtUserId'];
   $password = $_POST['txtPassword'];

   // check if the user id and password combination exist in database
   $sql = "SELECT user_id
           FROM tbl_auth_user
           WHERE user_id = '$userId'
                 AND user_password = PASSWORD('$password')";

   $result = mysql_query($sql)
             or die('Query failed. ' . mysql_error());

   if (mysql_num_rows($result) == 1) {
      // the user id and password match,
      // set the session
      $_SESSION['db_is_logged_in'] = true;

      // after login we move to the main page
      header('Location: main.php');
      exit;
   } else {
      $errorMessage = 'Sorry, wrong user id / password';
   }

   include 'library/closedb.php';
}
?>

The part that confuses me is the library directory.  Do I actually have to create a library directory and the files called closedb.php and opendb.php or is this some apache built in server feature.  If i do need to create the directory... are these files already created?  The reason I ask is because in the tutorial he gave no source to these files, so I am wondering if they are a standard web script that can be obtained someplace.

Thank you for any input you may have in advance,

$username = $_POST['username'];
$email = $_POST['email'];
$password = md5($_POST['password']);
$password2 = md5($_POST['password2']);
$location = $_POST['location'];
$genre = $_POST['genre'];
$date =

what should I write to insert date and time in the database and what type should I specify on the database side?

thanks a lot

Jim,Smith,1234 Main Street,Anytown,NY,12345,206,123-3456

I need to read the file andd then output the data (name and phone number) in a two columm table like this:

Smith, Jim        (206) 123-3456

The data also needs to be sorted by last name.

I assume I will be using an array, but I'm not sure how to do it.

If you can help me, email me at grz@wi-net.com.

Thanks,

i dont like the fact that the field is no longer seen as empty if it consists even of one space

how to make that the field is empty although it would contain even 100 spaces?

thanks

NEW EDIT TO THIS TOPIC:

what usually results in these errors is poor script design.  when one processes a form, they should do it BEFORE OUTPUTTING ANYTHING TO THE BROWSER.  there is NO reason that the process cannot be operated in the header of the document, before any HTML is output.

let's take a common example.  the programmer wants a login form which checks the username and password against the database.  if they don't match, then don't set a cookie remembering them and tell them it failed.  if they do match, set the cookie and send them to a member page.  many will do:

[HTML starting the page and layout]
[PHP processing the form]
[form code]

because they can simply echo any errors straight from PHP right above that form.  they can also send a success message, set the cookie, and header() them off on their merry way without seeing the form again.  it's a logical place to put this code.  think again.  you'll (perhaps not so) obviously get header errors when you go to use setcookie() and header().  if the login fails, it's dandy, but if you have a successful login the user gets nowhere.

answer:  put the processing in the header, and store the results in variables.  perhaps a $result variable that is 1 if successful, 0 if failed.  then $output that contains either a success message or customized error messages.  the new code would look like:

[PHP processing the form (if it was sent) and storing the results]
[HTML starting the page and layout]
[PHP echoing the results]
[form code if failed - exit(); if successful]

this will solve your header errors and will make for much more maintainable and readable code.  if you want to redirect them elegantly (with a success message), use a <meta> refresh redirect.  header() should only be used in instances where instant redirection is desired.

how would i make an if statement so if first variable is the same as second variable it displays the word "same" and if they are different it displays the word "different"

thanks
