PHP - Php Session Not Echoing
I have a login form at
http://cloydprojects.com you can login with username: test password test If you login the script works correctly, but if you type in the wrong info my session is not showing here is that I have. my login script Code: [Select] <?php session_start(); ?> <link href="signUp.css" rel="stylesheet" type="text/css" /> <?php include("db.php"); include("classes/class.account.php"); $Acc = new account; $u = $Acc->clean($_REQUEST['usernameLogin']); $password = $Acc->clean($_REQUEST['passwordLogin']); $p = md5($password); $get = mysql_query("SELECT * FROM users WHERE username = '".$u."' and password = '".$p."'"); $find = mysql_num_rows($get); if ($find == 1) { $info = mysql_fetch_assoc($get); $_SESSION['LoggedIn'] = $info['uID'].'.'.$info['username'].'.'.$info['email']; } else { $_SESSION['LoggedFailed'] = '<div id="ErrorBox">Incorrect username/password!</div>'; } //there is more just not showing it here is my index script where the error should be showing! Code: [Select] <div class="stylized"> <?php if(isset($_SESSION['LoggedIn'])) { echo '<h1> Welcome! </h1>'; echo '<a href="logout.php">logout!</a>'; } else { echo $_SESSION['LoggedFailed']; session_destroy(); ?> <form id="instantform" name="form" action="loginUser.php" method="post"> <h1>Login</h1> <label>Username <span class="small">The username you created!</span></label> <input type="text" name="usernameLogin" id="usernameLogin" /> <label>Password <span class="small">Case sensitive!</span></label> <input type="password" name="passwordLogin" id="passwordLogin" /> <button type="submit">Login</button></div> <div class="spacer"></div> </form> <?php } ?> </div> Similar TutorialsI am having trouble resolving an error. Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/s519970/public_html/header.php:27) in /home/s519970/public_html/admin/login.php on line 2 What I can gather is I can't use "header (Location: 'admin.php')" after i've used session_start(). I have tried to replace the header (Location: 'admin.php') with this: echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php. Code: [Select] <?php session_start(); if(isset($_SESSION['user'])) echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; ?> <div id="loginform"> <form action="dologin.php" method="post"> <table> <tr> <td><span>Username:</span></td> <td><input type="text" name="username" /></td> </tr> <tr> <td><span>Password:</span></td> <td><input type="password" name="password" /></td> </tr> <tr> <td colspan="2" align="right"><input type="submit" name="login" value="Login" /></td> </tr> </table> </form> </div> I have tried using require_once('yourpage.php'); before my <head></head> tags in the header document where I've specified the html information but this doesn't seem to work. I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this. Any advice is greatly appreciated! in this page http://maximaart.com/newscp/ i have this problem Code: [Select] Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/maximasy/public_html/newscp/index.php:1) in /home/maximasy/public_html/newscp/index.php on line 2 my source code is <?php session_start(); include_once("config.php"); include_once("functions.php"); $errorMessage = ''; if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) { if ($_POST['txtUserId'] === "$user" && $_POST['txtPassword'] === "$pass") { // the user id and password match, $_SESSION['basic_is_logged_in'] = true; require("main.php"); exit;?> I am trying to create an index page which contains registration and login field the problem that i get is on successful login a warning is displayed session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp\htdocs\Eventz.com\index.php:116) in C:\xampp\htdocs\Eventz.com\index.php on line 235 This is the login part of my index.php this tag is inside an html table below the login form I also have a registration form and its php code above the login form Code: [Select] <?php if (isset($_REQUEST['pass'])) { $id=$_POST['id']; $pass=$_POST['pass']; $conn =mysql_connect("localhost","root",""); if (!$conn) { die('Could not connect: ' . mysql_error()); } /* checking connection....success! */ $e=mysql_select_db('test', $conn); if(!$e) { die(''.mysql_error()); } else { echo 'database selected successfully'; } if (isset($_REQUEST['id']) || (isset($_REQUEST['pass']))) { if($_REQUEST['id'] == "" || $_REQUEST['pass']=="") { echo "login fields cannot be empty"; } else { $sql=mysql_query("Select email,password from login where email='$id' AND password='$pass'"); $count=mysql_num_rows($sql); if($count==1) /* $count checks if username and password are in same row */ { session_start(); $_SESSION['id']=$id; echo "</br>Login Successful</br>"; } else { echo "</br>invalid</br>"; echo "please try to login again</br>"; } } } } ?> Any help or suggestion would be appreciated hi everyone. i'm wondering what the best way is to create a session variable and pass it to an iframe. i need to do something along these lines, but it doesn't seem to pass the ID. Any hints on how i should accomplish this? Code: [Select] session_start(); $_SESSION['ID']=$_GET['ID']; // id from previous page $ID=session_id(); <iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe> I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content. To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in? My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive. Hello guys, I want to get the values of 3rd level of my referral but it did not echo any value but if i put the ref id directly on the code, it will echo the values. why is it so? or am i doing it the wrong way? in my database i have a table test_referral id acct_name ref_id refer_id 1 john J1234 0 2 bull B3456 J1234 3 doe D5567 J1234 4 frank F7788 J1234 5 jimmy J9990 J1234 6 tommy T6784 F7788 7 tom T9988 F7788 8 girly G8866 D5567 9 fred F0099 J9990 10 ronaldo R7722 B3456 thanks

Thanks for any help given This code is suppose to echo out ALL the custom pages that are in the database, but it's only show ONE.

Ive checked all the if statements ive changed the order around. still nothing. all of them work other than file format not supported. I can get this one to work...but at the cost of no file selected not working...help! Hi, I have this variable that checks which page we're on: Code: [Select] <?php $checkit = $_SERVER['PHP_SELF']; ?> and I need to echo some text depending which page we're on. I am using this code to do so: Code: [Select] <?php if ($checkit=="index.php") { echo "this is the home page"; } if ($checkit=="index2.php") { echo "this is the other page"; }?>...but nothing is printed. what am i doing wrong? Thanks Hey i'm just woundering how i would echo numbers from a database like 1000000 lets say 1 million how would i go about on echoing it like this 1,000,000 ZhsHero Hi, I'm trying to echo some error message like this: Code: [Select] <?php echo (isset($_GET['failed']))?'.CNT_TXT_MYERRORMESSAGE.''; ?> i know it must be a syntax error....but I'm a newb.... Thanks I want to echo the contents of column 4 for my username only, and it doesn't show anything. I can do if ($memberQuery->fetchColumn(4) < 2)() though. Code: [Select] $host = 'localhost'; $database = ''; $db_username = ''; $db_password = ''; if (($db = new PDO("mysql:host=$host;dbname=$database", $db_username, $db_password)) == NULL) { echo $db->getMessage(); } $memberQuery = $db->prepare("SELECT * FROM members WHERE username=:username"); $memberQuery->execute(array(':username' => $_SESSION['username'])); $result = $memberQuery->fetchColumn(4); echo "$result"; i am having issues checking which value is checked in a form. here is my code for it: Code: [Select] <input type="radio" name="accountActivation" id="no" value="no" checked=" <? if (isset($register_errors)) { if (($_POST['accountActivation']) == "no") { echo "checked"; } } ?> " /> when i first open the page, no is checked. why is this, when there should be no errors, and the radio should not even be checked in the first place? |
