PHP - I Have A Header Error Question (and, Yes, I Did Read The Sticky At The Top)
I have a web site with a user login requirement that has worked splendidly for months. I also have a development version of my site on my laptop, localhost. At the moment, I have identical code on both the development and production sites. I'm getting some header error in production, but not on development.
Is it guaranteed that my page is generating some white space, or is it possible that there may be another issue at hand (I'm fairly non-technical, so I'm grasping here - my web host upgraded to a different PHP version that is creating whitespace in production while development on my laptop is a different version of php, my web host has done something else that is causing this, fill in the blank with your own conspiracy theory)? Any reading material out there (besides the php.net manual) that explores what may be going on? Thanks in advance - this community has been wonderfully helpful for me over the last year! Similar Tutorialshi there, seems like I'm getting a fairly common beginners php error but as I'm using a number of differant files and as I'm not entirley clear on a couple of things I thought I'd tap into the immense php talent on this site here's the error - Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\Epointment\index.php:4) in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\Epointment\ot\views\header.php on line 38 I have an index page that allows a user to log on, the processing go's away and checks the usual stuff then reloads the login page with the user detail or just reloads the login page with the user/password fields blank. This seemed to be working ok until I put my files onto another web server that had output_buffering turned off. here's part of the login page Code: [Select] <html> <head><title></title></head> <body> <?php ini_set("display_errors", "1"); error_reporting(-1); $dir = dirname(__FILE__); require_once "$dir/ot/ot.php"; ot::include_view('header', array('account' => null)) ?> // various stuff <p>Please login below</p> <?php ot::include_view('login_form')?> the ot.php file doesn't have any echo's or print_r's etc if that helps?? here's the header.php file.. <?php Code: [Select] if (ot::get('do_logout', 0) == 1) { ot::destroy_session(); header("Location: http://{$_SERVER['SERVER_NAME']}{$_SERVER['PHP_SELF']}"); exit; } elseif (self::post('do_reset_password')) { ot::do_reset_password($err); echo "$err"; } $adb = ot::db('account'); $account = null; $error = ""; $id = ot::account_id(); if ($id) { $account = ot::account_from('id', $id); $res = ot::do_change_password($account, $err); if ($res) { echo "<p>Password Changed Successfully</p>"; $account = $res; } else if ($err) { echo "<p>Error: $err</p>"; } $res = ot::do_change_email($account, $err); if ($res) { echo "<p>Email Changed Successfully</p>"; $account = $res; } else if ($err) { echo "<p>Error: $res</p>"; } } else { $account = ot::do_login(); if ($account) { header("Location: http://{$_SERVER['SERVER_NAME']}{$_SERVER['PHP_SELF']}"); exit; } } ?> here's the ot::do_login function Code: [Select] public static function do_login(&$err="") { $adb = ot::db('account'); $e = self::post('email'); $p = self::post('pwd', '', false); if (self::post('do_login') && $e && $p) { $ao = self::account_from('email', $e); if ($ao) { if (self::validate_login($e, $p, $ao)) { //echo "\n"."hit2"; $_SESSION['id'] = $ao->id; return $ao; } } $err = "Invalid email or password"; return false; } } and here's the login_form.php, which is called from ot::do_login from header.php ... Code: [Select] <form action='<?php echo $_SERVER['REQUEST_URI']?>' method='post' > <p>Email:<br/><input type='text' name='email' /></p> <p>Password:<br/><input type='password' name='pwd' /></p> <p><input type='submit' name='do_login' value='Login' /> <input type='submit' name='do_reset_password' value='Reset Password' /></p> </form> Any pointers or useful things I've not posted? is this bit of code from above ok? as in I'm doing some php stuff before the header() function gets used? Code: [Select] <html> <head><title></title></head> <body> <?php ini_set("display_errors", "1"); error_reporting(-1); $dir = dirname(__FILE__); require_once "$dir/ot/ot.php"; ot::include_view('header', array('account' => null)) Ok here is what I am a little confused about, dealing with md5 for example - the md5 of anything generates a 32 character hash - I have a login form that supplies a user and pass to check in the database - user password stored as hash in database, so that protects visual of seeing the database, if it was somehow possible - now on submission I process that form Code: [Select] <?php // some random salt $salt="2bhga6YHJuhyhshabshbnla;"; // user password 10 digits $pass="bLac123Kow" // hash the password $hash=md5($salt.$pass); // query db to compare user and hash $sql=mysql_query("SELECT * FROM users WHERE user='$user' AND pass='$hash'"); // process result if match login else use ip logging and ban after 5 attempts for 15mins redirect with error Ok my point of confusion is even with the hashing, the task for the hacker is only trying to find a matching or similar original password that generates the same 32 character md5 hash is it not? As every attempt made would use the same process script in my login already applying the salt for them for the comparison in a brute force attack. Lets assume the attacker has already guessed a user name and uses that for all the attempts. I am also aware that I have used a 10 character password which increases the brute force attack time. So no matter how I process the password with hashing, I have to do the same process in my login form processing to compare it to the stored hash or they wont match? Is that how it works or have I got that wrong? I am just looking for the best way to setup a login system, as I have used the above method for quite some time and not really sure if it is effective, and want to understand it better, am I using the md5 setup the best or right way? i've seen this error pop up time and time again, and the answer is ALWAYS the same. please look here before you post it. the problem is you are outputting to the browser (whitespace included) before sending a header. this is unallowed. remove output prior to the header, or use OUTPUT BUFFERING. 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. Hey, I'm trying to open a .php file and read a comment block that is in the beginning of the file. I'm having some trouble in that nothing is being echoed out. Here is the reading file: <?php $fb = fopen("tepl.php", "r"); $data = fread($fb, 8192); fclose($fb); var_dump($data); ?> here is the file (tepl.php) being read: <?php /* Name: Test Plugin 1 URI: http://www.theorangeday.com/plugintest/ Description: This is just a test plugin because I need to test how this thing is going to work overall.

Does anyone knows the mistake i keep doing? This topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=319414.0 I currently have a login script in place on my site and to get to certain pages you have to be logged in to get to. So when a user tries to go to one of those pages and is not logged in it sends them to the login page (which is great) But on the login page once they login it uses " header('Location: index.php') " to automatically send them to the index page logged in. How can i dynamically see what page they are coming from that way when they login I can send them back to where they where trying to get to to begin with. (like if they click on "Profile" and they are not logged in it sends them to "login" then they login and it currently sends them to "index" I want it to dynamically know to send them back to "profile" instead) If this doesn't make sense and i will try and explain it better But if you understand and know how to do this please help Thanks ahead of time!

I'm a little bit new to php and it seems I am getting a small issue that I am not able to resolve...

I placed that code for the search bar above the html tags but i keep getting the error here is my coding Code: [Select] <?php mysql_connect("localhost", "user", "pass") or die(mysql_error()); if (isset($_POST['submit'])) { $search = mysql_real_escape_string($_POST['search']); $type = mysql_real_escape_string($_POST['type']); if ($type == true) { header("Location:http://www.link.com/searchresults.php?subdirectory=$search&type=$type"); } } ?> The org variable holds the value of the folder name. The problem is that the header is sending out ".$org." and not the actual value of $org. Example output url: http://127.0.0.1/application/".$org."/display/trackingboard.php I want this url if the value is test: http://127.0.0.1/application/test/display/trackingboard.php Thanks! Code: [Select] $org = "test"; header('Location: ../application/".$org."/display/trackingboard.php'); I hate header errors...
