PHP - Header Not Redirecting

This topic has been moved to PHP Applications.

http://www.phpfreaks.com/forums/index.php?topic=350027.0

Hey guys,

If my php looks like this: (notify if errors)

<?php

$user=$_POST['user'];
$pass=$_POST['pass'];

if(($user=="testing") && ($pass=="testing123")) echo "Access Granted";
if other echo "Access Denied!"

?>

If after the "Access Granted" It could redirect the user to another webpage, index2.html for instance.

Thanks in advance 

I do know that nothing should be printed out before a header() redirect, yet this error message:

Code: [Select]
Warning: Cannot modify header information - headers already sent by
Is pointing to a meta tag, why does a meta tag become considered as a print out?

The meta tags are as usually located in between the header tags of the whole website.

What would you rather recommend in this case to accomplish a redirecting after a successful log in?

Hello,

I'm having some problems with a redirect situation.  I start on a page called Create Assignment.  From this page I pass (using GET) the variable assignment_id to a page called Add_questions (the user can add questions to this specific assignment).  When a user wants to add a question, they hit a link which brings them to my Database Update script.  All works great so far!  After the update, however, I want to redirect them BACK to the Add_questions page while keeping the same Assignment number.  I've tried using:
header('Location: list_assignment_question.php?assignment_id'); but I get this error:

Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/algebra_book/main_scripts/db_insert_assignment_question.php:6) in /Applications/MAMP/htdocs/algebra_book/main_scripts/db_insert_assignment_question.php on line 12

Any thoughts?  I'd be more than happy to provide more code as needed.

i am trying to redirect a user to a certain page, if the credentials are not right.  if there is no session user, they are kicked out.  if it is set, but to the guest account, they go to the login page with a special error message.  here is my code for it:

Code: [Select]
if (!isset($_SESSION['user']))
{
  header('Location: portal.php?logintocontinue');
exit;
}
elseif($_SESSION['user'] == "guest") {
header('Location: portal.php?invalidLogin');
exit;
}
else {

}
after attempting to run the page, with session user = guest, i get this error message: The page isn't redirecting properly.

does it have to do with headers already being sent?

Can Someone please look at the following zip file and edit index and code-gen so when someone refer required amount of visitors, php echo will redirect them to complete.php   I have got css and js but not uploading as they are too big   Thanks (please help me)    script.zip   29.95KB   3 downloads

Is it okay to redirect a user to another page - which displays an outcome message - after a form is submitted?

Hello everyone, i have a "bug" i'd like you to see and help me solve if possible.

Let me tell you about when the redirection starts.
In my script, it checks if the two words you've entered in two boxes, if they match with the two words on the mysql database then send them to /php/userpanel.php
if they doesnt send them to /php/loginerror1.php

My problem is, that when you've been redirected to ex. /php/loginerror1.php
then when you click to a new page in the menu, it sends you to /php/loginerror1.php/index.php

/php/loginerror1.php also dont have any design, i think it doesnt load the .css properly.

Anyone had this, or anyone knows how to fix it?

Thanks Niixie

Is there anyway to do this:

my form is posting to self, then checking login creds. if they are incorrect it spits out "invaild bla bla" but if they are correct send them to a different page?

here is the short version of what I have.

if(isset($_POST['submit'])) {

//check inputs vs db

if ($check) {
header("Location: http://". $_SERVER['SERVER_NAME']."/include/process_renew.php");
} else { 
echo "<font color='red'>Username or Password did not match.</font> <br /><br />";
   }
}


}

I tested it using echo first and it worked fine then replaced the echo with header and now when I submit it just refreshes the page.

is this not possible?

Hi again,
           I have created a comment script, which is working pretty good. Now the problem I am facing is for instance this is one page www.mysite.com/blah1 and this is another www.mysite.com/blah2. They both have options to comment, now what is happening some one posts on blah2, it redirects to blah 1 and some one posts on blah 1 redirects to itself  what I want to achieve is when a person posts a comment on any given page PHP redirects the person to the page where they posted from (itself) not the other one. Thanks any help or guidance would be appreciated. I hope was clear enough!

Hi guys

Another basic question.

I have this dynamic link when I click it, it redirect to this link below,
Code: [Select]
http://samplesite.com/adventure/\'google.com\'

How do I remove the main site --> samplesite.com redirect only to google.com?

I also tried to remove the two slashes using stripslashes() but it won't.

By the way here is the stripslashes() codes,
Code: [Select]
while ($db_field = mysql_fetch_assoc($result)) {
$title = $db_field['title'];

print "Title: " . stripslashes($title) . "<br>";
print "Description: " . $db_field['description'] . "<br>";
print "Version: " . $db_field['version'] . "<br>";
print "Started: " . $db_field['started'] . "<br>";
print "Finished: " . $db_field['finished'] . "<br><br>";
}


Thanks in advanced.

For some reason the below is always redirecting to ./index.php?usercp=ideas&message=error

I'm assuming it's something to do with mysql_affected_rows.


<?php
session_start();
require_once 'db_select.php';
require_once 'func.php';
$donor_id=$_POST['donor_id'];
$donor_id=sanitize($donor_id);
$username=$_POST['username'];
$username=sanitize($username);
$name=$_POST['name'];
$name=sanitize($name);
$amount=$_POST['amount'];
$amount=sanitize($amount);
$idea_message=$_POST['idea_message'];
$idea_message=sanitize($idea_message);
$_SESSION['idea_message']=$idea_message;
$subject=$_POST['subject'];
$subject=sanitize($subject);
$_SESSION['subject']=$subject;
$confirm_agreement=$_POST['confirm_agreement'];
$confirm_agreement=sanitize($confirm_agreement);


if($subject==""){
$error0=1;
}
else{
$error0=0;
}

if($idea_message==""){
$error1=1;
}
else{
$error1=0;
}

if(($confirm_agreement!="no" && $confirm_agreement!="yes") || $confirm_agreement=="no"){
$error2=1;
}
else{
$error2=0;
}

$error="".$error0."".$error1."".$error2."";

if($error!="000"){
header("Location: ./index.php?usercp=ideas&error=".$error."");
}
else{
$sql="INSERT INTO $tbl_name5 (message_number, donor_id, username, name, amoutn, message) VALUES ('$message_number', '$donor_id', '$username', '$name', '$amount', '$message')";
mysql_query($sql);
if(mysql_affected_rows()==1){
header("Location: ./index.php?usercp=ideas&message=submitted");
unset($_SESSION['idea_message']);
unset($_SESSION['subject']);
}
else{
header("Location: ./index.php?usercp=ideas&message=error");
}
}
?>

Hi Guys,   I have a Url which allows me to send sms to a number. The url usually asks for id , number and few other things. When I paste the url in browser and press enter it opens and a sms is sent.   Now I want to code in php a way to send sms without redirecting to that page. For e.g. I ask user his mobile number and then I should be able to call/run that url and a sms should be sent to his number. If I use php header then it redirects to that page. I have tried using file_get_contents and php cURL but it has not worked so far.   Can you guys help me out ?   Thank you,   Cheers, GR

The following should be redirecting to a certain page based upon the variables given. If someone is logged into the admincp but enters the address index.php?admincp=users, all that shows up is a blank page, it should re-direct back to the admincp main page; aka index.php?admincp. Everything other than this is working... It's just not going back to the admincp when index.php?admincp=users is entered.

I am trying to integrate facebook login into my application.  If the user isn't logged in,  I want to make sure that they get sent to the index page, but this doesn't work.

Code: [Select]
<?php

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
$user = null;
    //echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
  }
} else {
header('Location: /');
}

?>

Any thoughts on how to fix?
