PHP - Header Question
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! Similar Tutorialsthis question seems so stupid, but i really want to know the best way to write this code. let say i have this code: if(empty($num)) { header("Location:index.php"); } is it okay if i write it down like this? if(empty($num)) { header("Location:index.php"); } i mean there is a whitespace behind header() thanks in advance 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'); So say i have this: Code: [Select] <link rel="stylesheet" media="all" type="text/css" href="_css/styles.css" /> now the file that is linking to that is 3 directories deep, besides using a rel or absolute link, could i define the path by using something like this Code: [Select] <link rel="stylesheet" href="<?php require($_SERVER['DOCUMENT_ROOT'] . "/_css/portfolio-styles.css"); ?>" type="text/css" /> but this is actually opening the CSS in the header thanks for any explanation on how to do this Hi: Does this header redirection: Code: [Select] header("Location: http://www.WebSite.com/Page.php"); Happen on the server, and then get sent to the browser, or is it something that happens on the users computer? 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! This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=350027.0 Hello everyone, I'm just starting out with PHP as I need to create an online bookstore for a school project. I'm working by a magazine which should teach you exactly how to do this using PHP, but I've had a bunch of problems with the code they use and I don't really know what's going on. Anyway, this looks really simple and basically what it does is allows you to post a comment on a book, then returns you to the book's page. Problem is, I'm getting the Header may not contain more than a single header, new line detected. error and I can't figure out why. I've tried researching into the matter but all the cases I found had to do with returning to an url, which is not my case. Anyway, here's the snippet of code: The form: Code: [Select] <div style="width:400px; border:1px solid #ffffff; background-color:#F9F1E7; padding:5px"> <b>Adauga opinia ta:</b> <hr size="1"> <form action="adauga_comentariu.php" method="POST"> Nume: <input type="text" name="nume_utilizator"><br><br> Email: <input type="text" name="adresa_email"><br><br> Comentariu: <br> <textarea name="comentariu" cols="45"></textarea><br><br> <input type="hidden" name="id_carte" value="<?=id_carte?>"> <center><input type="submit" value="Adauga"</center> </form> </div> The script adaugare_comentariu.php: Code: [Select] <?php ob_start(); include("conectare.php"); $numeFaraTags=strip_tags($_POST['nume_utilizator']); $emailFaraTags=strip_tags($_POST['adresa_email']); $comentariuFaraTags=strip_tags($_POST['comentariu']); $sql="insert into comentarii (id_carte, nume_utilizator, adresa_email, comentariu) values(".$_POST['id_carte'].", '".$numeFaraTags."','".$emailFaraTags."','".$comentariuFaraTags."')"; mysql_query($sql); $inapoi="carte.php?id_carte=".$_POST['id_carte']; header("location:urldecode($inapoi)"); ob_end_flush(); ?> conectare.php connects to the mysql database. $inapoi is the variable which returns the user to carte.php (the book he posted a comment on), where id_carte is the book's unique id. I'm getting Header may not contain more than a single header, new line detected on line ten, which is the header line. Can anyone help me? I've been stumped on this for a few days now and I've just let it pass and started working on other bits, but it's bugging me too much and I'd like to fix it. when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement. Here is code I was experimenting with: <html> <body> <form action="" name="test" method='POST'> <input type="radio" id="sex" value=1 checked><label>Male</label> <input type="radio" id="sex" value=2><label>Femaleale</label> <?php $result = "value"; if ($result == 2) echo "<input type='int' id='gradYear' size='3' required>"; else echo "Not a female!" ?> <input type="submit" value="GO"> </form> </body> </html> The code passes debug, however, Not a Female is displayed. My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped. Thanks for the assis in advance. How do I get this to put in the pilotID? Code: [Select] header("Location: logbook.php?id=" . $pilotid); Thanks! Hi everyone, I have a login area, and i also have set up for me is a view page... the view page is each user's sort of profile, it gets id and displays relevant content. i was wondering if i could get the id or post rather through a re-direct on log in? for example user logs in with username and password, user is re-directed to the view page like this: header( "refresh:5;url=view00=id.php " ); echo '<h1>You will be re-directed in 5 seconds...</h1>'; user is taken to view page where they can edit bit on it. So far though i'm getting page not found error? first of all is this possible? if not whats the correct way/better way? Thanks Can some one help please i always get this wrong dont now why keep saying header already been sent any help please and how to fix it Code: [Select] <?php session_start(); $conn = mysql_connect(""); $db = mysql_select_db("", $conn); if(isset($_POST['submit'])){ $user = mysql_escape_string($_POST['user']); $pass = mysql_escape_string($_POST['pass']); } if(empty($user) && empty($pass)){ exit; }else{ } ?> <?php $sql = mysql_query("SELECT * FROM useradmin WHERE dbusername= '".$user."' AND dbuserpass= '".$pass."'")or die(mysql_error()); $row = mysql_fetch_assoc($sql); $count = count($sql); $u = $row['dbusername']; $p = $row['dbuserpass']; if($u == $user && $p == $pass){ $_SESSION['access'] = "$u"; header("location: index.php"); }else { echo "Sorry there as been a problem!"; exit; } ?> Hi is there a way that i can set header not go anywhere like the problem with this is that it still goes to the second header is there a way i can set if none do nothing exit? and else do the second header?? Code: [Select] <?php if ($_POST['agents']=="none") { header("location:#"); exit; // header("Location: {$_SERVER['PHP_SELF']}"); } else { header("location:http://www.xxxxxx.co.uk/tv/".$_POST['agents']."/index.php"); } ?> Hi there, I have a form which displays a "successful" message if the form is completed correctly. However, I want the form to go to another url if it is successful. I have tried this, but I get the "headers already sent..." message // Add New Subscriber Success Message $successMsg = header('Location: http://www.example.com/'); is there another way to forward onto another page? Thanks Hey guys, I have a problem, i'm using ob_start to send multiples headers and it works but the problem is that my metada is not being sent, when i remove the ob_start it gets sent. Is there a way i can allow more info to be sent with ob_start? or should i use other methods to redirect to pages? i dont want to use javascript or meta http because they are not very reliable is there any other way? Thanks for help. Does starting a Session send data to the Header? Debbie Can someone assist with this, the form works, but the end user cannot simply click on reply, they have to copy/paste. I think it is just a header issue, but i'm not sure and the person who wrote this script is no longer availalble...any help would be much appreciated! Code: [Select] <?php if ($_POST['post'] != '') { $to = 'fetch@domain.com'; $subject = 'Appointment Request'; $message = "A user on the website has submitted an appointment request. Find their details below.\n\n"; $reqd = array('name', 'email', 'phone', 'phonetype1', 'petname'); $disregard = array('post', 'Appointment_Mail_'); $breaks = array('break', 'break2', 'break3'); foreach($_POST as $key=>$value) { if (in_array($key, $reqd) && $value == '') { $error .= '- Fill out '.$key.'<br />'; } elseif (!in_array($key, $disregard)) { if (in_array($key, $breaks)) { $message .= "\n"; } else { $message .= ucwords($key).": ".stripslashes($_POST[$key])."\n"; } } } if ($error == '') { mail('fetch@domain.com', $subject, $message, 'From: domain.com <noreply@domain.com>'); header('Location: http://www.domain.com/thanks.html'); die(); } else { $error = 'Please correct the following errors:<br />'.$error; } } ?> If I do something like header(Location: www.url.com). Is there a way that url.com would be able to get the IP from the server that did the redirect? It looks like $_SERVER["REMOTE_ADDR"] returns the clients IP address which isnt what I need. Thanks Hi, i would like to encode a url example. $error="You must be signed in"; $enc=urlencode("http://localhost/finxed/asku/asked.php?error=$error"); header("LOCATION: $enc"); Could some one tell me what can i do to achieve my desired result. I want the header to take to the LOCATION, which is $enc but i wanted it to be encoded when displayed in the url field. The current code is not working. Hello, I have read the READ BEFORE POSTING about the headers, and that doesn't seem to answer my problem. I have 2 if statements in included files that have header statements with location. I don't understand why I am still getting the header error (Warning: Cannot modify header information) if I have my headers in if statements. Take a look home.php <?php require("header.php"); require("isadmin.php"); ?> header.php <?php session_start(); require_once("includes/dbconn.php"); if($_SESSION['username']) { echo "Welcome ". $_SESSION['username']; }else{ header("Location: login.php"); } $session = $_SESSION['username']; $logout = "<a href='safelogout.php'>Log Out</a>"; echo $logout; ?> <title>Website</title> isadmin.php <?php mysql_select_db('center'); $session = $_SESSION['username']; $sql = "select * from users where username='$session'"; $result = mysql_query($sql); $row = mysql_fetch_array($result); $perm = $row['permission']; if($perm == 2) { header("Location: admin/home.php"); } ?> I have the following 1. php page that stores sessions. press submit and... 2. ...goes to perl/cgi page to interface with an api only available in perl, then auto redirects via HTTP headers to... 3. ... a php page where depending on the result a field is added to database then emailed, etc... then... 4.... redirects to main page so really all the user sees is page 1 -> hits submit -> ends up on page 4 via redirects Is there a problem with using redirects? Could the user intervene and prevent these redirects? Thanks |
