PHP - Redirect Script Does Not Redirect Properly
I'm trying to put together a script that redirects visitors based on their IP, user agent and/or referral url. Basically I want the script to scan these three factors from the visitor, if any of them turn out to match my redirect-requirement it redirects the user. I know the code is horribly coded, I'm incredibly new to the php-scene and consider myself a complete noob. As you can see I want redirected visitors to go to google.com and un-redirected to msn.com(examples). Really thankful for all the help I can get! Right now nothing works, any suggestions?
<?php function redirect($page) { Header( "HTTP/1.1 301 Moved Permanently" ); header('Location: ' . $page); exit; } $referrals=array('pitchingit.org','referral2'); $badAgents = array("useragent1", "useragent2"); $deny = array("78.105.191..*","100.101.103..*"); if (in_array($_SERVER['HTTP_REFERER'], $referrals, FALSE)) { header("Location: http://www.google.com"); } else { header("Location: http://www.msn.com"); } if(in_array($_SERVER['HTTP_USER_AGENT'],$badAgents)) { redirect("http://www.google.com/"); exit(); } $add=$_SERVER['REMOTE_ADDR']; foreach ($deny as $ip) { if (preg_match("^.$add.*^",$ip)) { redirect("http://www.google.com"); } } redirect("http://www.msn.com"); ?> Similar Tutorials<?php require_once('upper.php'); $error_msg=''; if(!isset($_COOKIE['LoginIdCookie'])){ if(isset($_POST['submit'])) { require_once('database.php'); $LoginId=mysqli_real_escape_string($dbc,trim($_POST['LoginId'])); $Password=mysqli_real_escape_string($dbc,trim($_POST['Password'])); if((!empty($LoginId)) && (!empty($Password))){ $query="SELECT * FROM registration WHERE LoginId='$LoginId' AND Password=SHA('$Password') AND Flag='A'"; $result=mysqli_query($dbc,$query) or die('Not Connected'); if(mysqli_num_rows($result)==1) { $row=mysqli_fetch_array($result); setcookie('LoginIdCookie',$row['LoginId']); //$home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) .

I think cookie is not created as well.......... I can't understand where is problem???????/ please help me.................... Hi there,
I have a client who has a form on a php page that posts data to a script. That script process the post data and generates a pdf which comes back and is automatically downloaded in the user's browser. They would like to redirect the user to a separate page after this process is complete. I have tried redirecting by adding :
header( 'Location: http://www.yoursite.com/new_page.html' ) ;
Hey freaks! I have run into a bit of a snag and need a little guidance from the wise ones. I have a login script that users are redirected to if they land on restricted pages of my site. Initially, I used javascript (go back (-1) to get the user back to the page they were previously on after logging in - which worked fine...but only if they got their login credentials right the first time (which will probably never happen that often). The login form processes itself, so if they get it wrong, it comes back to login.php. I noticed that when I test logging in and purposely enter the wrong information, when I do enter the right info the login page comes back up because it was the previous url. I am not a big fan of JS and I am still fairly new to PHP, so I am not sure how to do this. I tried setting a session for the previous url using http referer (if the url did not equal login.php), but it did not like that at all! Undefined index, headers already sent, you name it...I got the error... I can post my code if need be, but it is just a basic login script (with a lot of Dreamweaver mumbo jumbo) that checks the username and pass in mysql. Any suggestions? Should I use a session for this? Or is it probably one of those switch statements that I am not remotely close in knowledge to writing myself...lol. Or even scarier...a custom function? Any help would be appreciated. Thanks! I am trying to find a way to check if a user has already entered their email address in my MySQL database.
If they have an entry then it jumps to another script that avoids the questionnaire, but if they have no entry, then they do the questionnaire.
I have tried using
header('Location: /questionnaire.html');
but I get this error warning:
Warning: Cannot modify header information - headers already sent by (output started at /homepages/43/d344817611/htdocs/Test/questionnaire_connect.php:14) in /homepages/43/d344817611/htdocs/Test/eCheck.php on line 16
The script I am using:
<?php
include('questionnaire_connect.php');
doDB12();
if ($_POST["email"] == "") {
header("Location: emailChecker.html");
exit;
} else {
//check that email is in list
emailChecker($_POST["email"]);
//get number of results and do action
if (mysqli_num_rows($check_res) < 1) {
//free result
mysqli_free_result($check_res);
header('Location: /questionnaire.html');
}else {
header('Location: /Alt_inputform.html');
}
}
//close connection to MySQL
mysqli_close($mysqli);
?>
The emailChecker is a function in the DB connect script:
function emailChecker($email) {
global $mysqli, $check_res;
//check that email is not already in list
$check_sql = "SELECT id FROM questionnaire WHERE email = '".$email."'";
$check_res = mysqli_query($mysqli, $check_sql) or die(mysqli_error($mysqli));
}
Is there another way I can redirect the program flow other than using Header?
Ok, I have a download script. The script is called like: http://www.site.net/index.php?action=downloadfile&filename=file001.zip&directory=directory12& The download file code is below. My site hosts quite a few files that get linked on other websites. Problem is, when that link is clicked, obviously it just starts the file download, as if it were a direct link to the file. What I need to do, is still have it download the file when the link is clicked, but I would also like it to redirect the browser to my homepage as well. I tried placing this after the download headers but it didn't work. header("Location: http://www.site.net"); Can anyone give me an idea how I can get the code to do that? Keep in mind that I'm not fluent in PHP. case 'downloadfile'; $filename = getGetVar('filename'); $directory = getGetDir('directory'); $current_dir = $uploads_folder_name; if ($directory != '') { $current_dir.="/$directory"; } $filename = basename($filename); if (!$grants[$user_status][DOWNLOAD]) { place_header($mess[111]); show_Contents(); break; } if (!file_exists("$current_dir/$filename")) { place_header($mess[125]); show_Contents(); break; } if (!is_path_safe($directory, $filename)) { place_header($mess[111]); show_Contents(); break; } list($upl_user, $upl_ip, $filestatus, $contents) = get_file_description("$current_dir/$filename", $comment_max_caracters); if ($validation_enabled && $filestatus == UNVALIDATED && !$grants[$user_status][VALIDATE]) { place_header($mess[111]); show_Contents(); break; } $size = filesize("$current_dir/$filename"); $daily_size = get_daydownload(); if (($max_daily_download_mb > 0) && (($size + $daily_size) > ($max_daily_download_mb * 1024 * 1024))) { place_header($mess[212]); show_Contents(); break; } $monthly_size = get_monthdownload(); if (($max_monthly_download_mb > 0) && (($size+$monthly_size) > ($max_monthly_download_mb * 1024 * 1024))) { place_header($mess[213]); show_Contents(); break; } increasefiledownloadcount("$current_dir/$filename"); increasebytecountdl("$destination/$userfile_name"); if (($user_status != ANONYMOUS) && ($logged_user_name != '')) // Update user statistics { list($files_uploaded, $files_downloaded, $files_emailed) = load_userstat($logged_user_name); $files_downloaded++; save_userstat($logged_user_name, $files_uploaded, $files_downloaded, $files_emailed, time()); } header("Content-Type: application/force-download; name=\"$filename\""); header("Content-Transfer-Encoding: binary"); header("Content-Length: $size"); header("Content-Disposition: attachment; filename=\"$filename\""); header("Expires: 0"); header("Cache-Control: no-cache, must-revalidate"); header("Pragma: no-cache"); // Decrypt file if encryption enabled if ($encrypt_filecontent) { decrypt_file("$current_dir/$filename", true); } else { readfile_chunked("$current_dir/$filename"); } exit; break; How can one re-direct a visitor, without using a header re-direct? I'd like a page to show up, then after about 5 seconds I need the visitor sent to another page. How can I do this? Hi,
Can someone tell me what this redirect will do?
RewriteCond %{HTTP_HOST} ^(www\.)?website\.com/microsite$
Thanks!
I have made a website (https://sokk.ga/), and I want to log the users public ip whenever he/she clicks one of the links, and then redirect him/her to the correct url. It's supposed to be a little php "script" between the main page and clicked link. The problem i face is that it shows the php code as plain text in the browser (chrome), no redirect or log. Here's my attempt:
<php? date_default_timezone_set("Norway/Oslo"); $ipFile = fopen("../logg/ip.txt"); $ipText = time("Y.m.d" + "-" + "H:i:s") + "-" + $_SERVER['REMOTE_ADDR'] + "\n"; fwrite("$ipText", $ipFile); fclose("../logg/ip.txt"); exit; header("https://sokk.ga/skole/"); ?> Hi guys, this is my first post here.

I will be in touch with you very soon. <?php } ?> As I said the code works fine just if I include the redirect, the form will not send me an e-mail as required. Could you help me out please? Thanks in advance, Jonathon Hi all, I have a page url that looks like this: jobs.php?view=view&id=5 Their is a login on this page, the form ends with this command: header("Location: ".$session->referrer); The fuction for this is: <?php function startSession(){ global $database; //The database connection session_start(); //Tell PHP to start the session /* Determine if user is logged in */ $this->logged_in = $this->checkLogin(); /** * Set guest value to users not logged in, and update * active guests table accordingly. */ if(!$this->logged_in){ $this->username = $_SESSION['username'] = GUEST_NAME; $this->userlevel = GUEST_LEVEL; $database->addActiveGuest($_SERVER['REMOTE_ADDR'], $this->time); } /* Update users last active timestamp */ else{ $database->addActiveUser($this->username, $this->time); } /* Remove inactive visitors from database */ $database->removeInactiveUsers(); $database->removeInactiveGuests(); /* Set referrer page */ if(isset($_SESSION['url'])){ $this->referrer = $_SESSION['url']; }else{ $this->referrer = "/"; } /* Set current url */ $this->url = $_SESSION['url'] = $_SERVER['PHP_SELF']; } ?> Basically $this->url = $_SESSION['url'] = $_SERVER['PHP_SELF']; seems to cut my url to: jobs.php instead of: jobs.php?view=view&id=5 Can anyone here tell me how to fix this? Thanks Guys I having trouble with my re-direct code on my php registration form. The form does submit data to the database but I'm getting the following error.

Your help will be greatly appreciated, thanks! if you go to this page here http://www.nikita-andrews.com/ingrid/?page_id=34 you see it is a three column grid layout if you click on image and go to single post you will see above the post it will either say HOME/PORTFOLIO/CURRENT PAGE or HOME/(CATEGORY)/CURRENT PAGE if you click on Portfolio or Category (whichever category it may be) it takes you back to a vertical list of all the post in the category like such http://www.nikita-andrews.com/ingrid/?cat=5 ... is there a way to redirect that link to go back to the 3 grid layout portfolio or portfolio category page? Using wordpress ... not sure where the php would be located. Im guessing in single.php but not sure where the code for that function is located in there Ok I know I can redirect using: header( 'Location: URL' ) ; Now, is there a way to delay this after a short while of displaying or would I have to use Javascript? Hi, I'm trying to figure out if I can get a redirect page to work, without needing to use the header("Location: page.php"); command. I know with asp, there is a response.redirect for redirecting pages, but, with the header, I can only use this, if there is no output before calling the command. Is there any method that can be used where I can process some code, if output is required, and depending on processing on the page, redirect it to another page, using a command similar to response.redirect? I have seen the http_redirect, but I can only see this working with clearing buffers etc. I have also a redirect_to("page.php"); command, but I cannot get this to work. I am using php 5. Any help would be appreciated. Thanks. <?php $get = fetch("SELECT number FROM dom") if "$get = 1" echo "<meta http-equiv='refresh' content='0;url=http://toxicpets.co.uk/down_for_maitenence.php'>"; elseif "$get = 0" echo "<meta http-equiv='refresh' content='0;url=http://toxicpets.co.uk/index.php'>"; ?> is this code right???
Ok, so let's say my website is bob.com - fine. Well, I want to have sam.com also, but can't afford to pay for Deluxe hosting. So I get the domain, but I forward sam's DNS servers to point at Bob, with masking on.
function get_redirect_target($url)
{
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$headers = curl_exec($ch);
curl_close($ch);
// Check if there's a Location: header (redirect)
if (preg_match('/^Location: (.+)$/im', $headers, $matches))
return trim($matches[1]);
// If not, there was no redirect so return the original URL
// (Alternatively change this to return false)
return $url;
}
$path = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo get_redirect_target($path);
The main problem here is that it's VERY slow. I'm also often getting a 500 error. Anyone have any ideas? Hello, Basicly, I want to make a php index, but make a certain redirect from it, for example, make: http://mysite.com/index.php?goto=forums Go to forums of my link choice, is their a simple code I can use?
