    login questions

    For some reason, the page doesn't load as I wrote intentionally the wrong password (to bring up the sentence refusing to log in.) I'm going to upload this as a txt file for privacy.

    For privacy? Search engines can index text files just the same as html.

    Your problem description isn't clear. What's happening?

    Where is the form tag in your code?

    testing result

    Ok I tested by changing the method from post to get and I got a result. There are two usernames and 2 passwords which one of them is the correct answer while the other one is blank. The reason for that is that I have one login for the average user and the other one is for the administrator.

    What do you recommend in this occasion? Should I combine the login somehow or leave it as 2 logins or what?

    Again, where is the form tag in your code?


    This is not an OR operation:
    PHP Code:
    if(!$_POST['username'] | !$_POST['pass']){ 
    This is an OR operation:
    PHP Code:
    if(!$_POST['username'] || !$_POST['pass']){

    Oh the form tag... sorry I missed that part. The txt file is actually an include file. The form tag is in the index:
    PHP Code:
    <?php // action=" echo $_SERVER['PHP_SELF']; "?>
    <form name="login" method="get" onSubmit="adminLogin(); userLogin();" target="_self">
    The 2 functions are empty but I left it there for now. (At first I was thinking of using AJAX for the login but couldn't figure it out because I didn't understand how the post method would work with AJAX). I doubted that I needed an action attribute so I left it out.

    As for the | and || I know the 2nd is OR but I got this code from this tutorial:
    http://php.about.com/od/finishedphp1...gin_code_2.htm

    The code worked until now. I see the problem now. It's because I put 2 usernames:
    Code:
    <div style="float: left; width: 100%; margin: 0px 0px 0px 0px; background-color: #7C7C7C; border: 1px solid #A5A498; border-width: 1px 1px 0px 1px;">

    To make things simpler I took the tutorial:
    http://php.about.com/od/finishedphp1...gin_code_2.htm

    again.

    The same error is occurring. After the die in the login page the hello doesn't appear(when I type in the wrong username. This means whatever code is underneath it will not print):
    PHP Code:
    if ($check2 == 0) {
        
    login();
    die(
    'That user does not exist in our database. <a href=register.php>Click Here to Register</a>');
    echo 
    "hello!!!!";

    login page: index.php
    PHP Code:
    <?php
    ob_start
    ();
    include(
    "dbconnection.php");
    function 
    login(){
    ?>
    <form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
        <table border="0">
            <tr><td colspan=2><h1>Login</h1></td></tr>
            <tr><td>Username:</td><td><input type="text" name="username" maxlength="40"></td></tr>
            <tr><td>Password:</td><td><input type="password" name="pass" maxlength="50"></td></tr>
            <tr><td colspan="2" align="right"><input type="submit" name="submit" value="Login"></td></tr>
        </table>

    Ok I was wondering why if I typed in the wrong username or password the die(""); would cause the code to stop printing whatever was left.

    So instead I used print(""); and the problem is solved.

    Now I wonder if I really need two (one for the administrator and the other for the average user) to login or just one because in the string, since it's in one <form> it's showing 2 usernames and 2 passwords and it's giving an error.

    I don't know what you mean by "2 usernames and 2 passwords". A well-designed system will most likely have a single login section. Once the user is authenticated, then permission settings or access control lists handle what he/she is allowed to do.

    Ok I put a checkbox to determine whether it's a user or the admin. But I don't understand how the members page is going to pick up the checked or unchecked?

    The problem above is dealt with by adding a checkbox of whether the one who logs in is the user or administrator. But I'm still have logging problems. It keeps logging out when I click on the url and entering.

    login page: index.php

    This is an OR operation:

    if(!$_POST['username'] || !$_POST['pass']){ 
    Ok I changed them.
    login/index.php
    PHP Code:
    if(!$_POST['username'] || !$_POST['pass']) {// makes sure they filled it in 
    register.php repeated twice
    PHP Code:
    if (!$_POST['username'] || !$_POST['pass'] || !$_POST['pass2']){ 
    But it's still giving the same problem. That is on the first attempt to log in it doesn't show the $myusername next to "welcome".
    PHP Code:
    if(isset($_COOKIE['ID_my_site'])){ //if there is, it logs you in and directs you to the members page
        
    $myusername $_COOKIE['ID_my_site']; 
    But on the 2nd attempt $myusername shows.
    And the 2nd problem is when I click on the url address bar and enter it logs out.

    I used 3 php files: login.php, logout.php and index.php.

    I think the checking the $_POST[] should be in the login.php. But then I'm guessing that the index.php page needs to read cookies which the login.php has set right?
    PHP Code:
    <?php
    # index.php
    session_start();
    $logged_in = isset($_SESSION['logged_in']);
    include(
    "../dbconnection.php");
    //say goodbye to magic_quotes_gpc! no false security.

    $errors = array();

    if(
    $_SERVER['REQUEST_METHOD'] == "POST"){
        if(empty(
    $_POST['username'])){
            
    $errors[] = "username was empty";
        }
        if(empty(
    $_POST['password'])){
            
    $errors[] = "password was empty";
        }
        if(empty(
    $_POST['email'])){
            
    $errors[] = "e-mail was empty";
        }
        if(
    count($errors) == 0){
            
    //fix magic_quotes_gpc() being on
            
    if(get_magic_quotes_gpc()){
                foreach(
    $_GET as $k => $v){
                    
    $_GET[$k] = stripslashes($v);
                }
                foreach(
    $_POST as $k => $v){
                    
    $_POST[$k] = stripslashes($v);
                }
                foreach(
    $_COOKIE as $k => $v){
                    
    $_COOKIE[$k] = stripslashes($v);
                }
            }
            
    //Checks if there is a login cookie
            
    if(isset($_COOKIE['ID_my_site'])){ //if there is, it logs you in and directs you to the members page
