    setting cookies?

    Hello...

    I am trying to make my script identify if the user is logged in or not, and if they arent then it will restrict calling the pages directly from the browser... I am pretty much basing my scripts on THIS THREAD...


    login.php
    PHP Code:

    <?PHP
    if (isset($_POST["login"])) {

        
    $frmuser $_POST["user"];
        
    $frmpass $_POST["pass"];
        
    //DB Variables
        
    $user "***"#username
        
    $pass "***"#password
        
    $dbname "***"#database name
        
    $tablename "***"#table name    

        
    $dbh mysql_connect ("localhost""$user""$pass") or die ('I cannot connect to the database because: ' mysql_error());
        
    mysql_select_db ("$dbname"); 

        
    $query "SELECT * FROM $tablename WHERE user='$frmuser'"
        
        if (
    mysql_db_query ($dbname$query$dbh)) {
            
    $result mysql_query($query);
            
    $num_rows mysql_num_rows($result);
            
            if (
    $num_rows != 0) { #if a username was found        
                
    while($row mysql_fetch_array($result)) {
                    if (
    $row["pass"] == $frmpass) { #if password matches the one in the DB
                        
    include 'index_logged.php';
                                            
    setcookie ("verified"true);
        
    header("Location:http://www.jdm71488.com/???????");
                                        }
                    else { 
    #if it did not match
                        
    echo "Password Incorrect"
                    }
                }
            }
            else { 
    #if a username was not found
                
    echo "Username Incorrect";
            }
        }
        
    mysql_close ($dbh); 
    }
    ?>
    I added <? include_once("protect.php"); ?> to all of my protected pages, and changed .html to .php on them all...

    When I log in with login.php it gives me access denied when I enter the right information. I enter the wrong username, or password it works fine, and it will display wrong username, or wrong password... But when I log in with my user and pass, it gives me the access denied page. Which is on the protect.php page found in the link... Pyro may know what I am talking about...

    My questions are... Is my login.php script right? I dont think it is where I added the set cookie part. Also where to I put the header for that cookie? Is it to my home page or where?

    Let's try it like this:

    PHP Code:
    if ($row["pass"] == $frmpass) { #if password matches the one in the DB
        
    setcookie ("verified"true);
        
    header("Location:[url]http://www.jdm71488.com/loggedinpage.php[/url]");

    Not sure what the file you included ( index_logged.php )was doing, so try it without.

    That is so cool... Now for a logout script... Do I have to unset the cookie? I know it automatically resets once the browser is closed if you are logged in or not. Should I leave it like this, or is there a way to unset or unverify it?

    I don't have time to look at all the thred but if your using sessions use this:
    PHP Code:
    <?PHP

    session_start
    ();
    session_destroy();

    header ("Location:index.php");

    ?>
    Then just have a button or link called "Logout" that links to this file! Hope that helps.

    Yes, what you do is just set the cookie to expire sometime in the past:

    PHP Code:
    setcookie ("verified"""time() - 3600); #expire 1 hr. ago
