PHP Cookies

[Drezard]

Hello, Here is my code for my class.php file. This file contains all of my functions to be used inside my PHP applications.

I want to set a cookie there with the $user and $pass function where the comment is:

[QUOTE]
// set cookie here
[/QUOTE]

Here my code:

[CODE]
<?php
/*
* Mysql.php
*
* This class is meant to do most of the interaction with the MySQL database.
*
* Last updated: December 16, 2006.
*/

/*
* This class contains these functions:
*
* connect()
*
*/

include ('constants.php');


/*
* MySQLDB contains most of the functions to interact with the MySQL database.
*/

class MySQLDB {

var $connection; // Contains all the connection to MySQL information

function connect() { // Connects to the MySQL database

$this->connection = mysql_connect(DB_SERVER, DB_USER, DB_PASS) or die(mysql_error());
mysql_select_db(DB_NAME, $this->connection) or die(mysql_error());

}

/*
* This function is used to check the username and password from a form against the one in the database.
*
* This function is used at login.
*
*/

function check_username($user, $pass) {

$query = "SELECT * FROM user_ids WHERE user='$user' AND pass='$pass'";

$result = mysql_query($query) or die ("Error in query: $query. ".mysql_error());

$count = mysql_num_rows($result);

if ($count == 1) {

return 0;

// set cookie here

}

if ($count == 0) {

return 1;

}

}

/*
* This function is used to check the username and password from a cookie or session against the one in the database.
*
* This function is used on every page to see if a user is logged in.
*/

function check_userid($userid, $pass) {



$query = "SELECT * FROM user_ids WHERE userid='$userid' AND pass='$pass'";

$result = mysql_query($query) or die ("Error in query: $query. ".mysql_error());

$count = mysql_num_rows($result);

if ($count == 1) {

return 0;

}

if ($count == 0) {

return 1;

}

}

/*
* This function contains the form to get the user to login.
*
* This function is used when you want to login
*/

function user_form() {

if (!isset($_SESSION['userinfo'])) {

echo "Please login:<br><br>";

echo "<form action='' method='post'>
    Username: <input type='text' name='user'><br>
    Password: <input type='password' name='pass'><br>
    <input type='submit' name='submit'>
    </form>";

$user = $_POST['user'];
$pass = $_POST['pass'];

$this->check_username($user, $pass);

}

if (isset($_SESSION['userinfo'])) {

echo "You are already logged in";

}

}

}

?>
[/CODE]

How do I set a cookie there?

From the PHP manual...

[code]<?php
$value = 'something from somewhere';

setcookie("TestCookie", $value);
setcookie("TestCookie", $value, time()+3600);  /* expire in 1 hour */
setcookie("TestCookie", $value, time()+3600, "/~rasmus/", ".example.com", 1);
?> [/code]

Yea, then it gives me the an error. Headers already sent.

- Cheers, daniel
