PHP - A Header Refreshing Problem

A Header Refreshing Problem	View Content

Hello!
My server hosting company has updated PHP from 4 to 5 version, and now the header function doesn't work very well anymore.
It does load the new page everytime, like it should, but the data is not always refreshed. Not until I click "reload current page" from the browser. I'm using Firefox 3.6.3.

Here's the code which worked just fine few days ago:
Code: [Select]
$url="thepage.php";
header("Location: ".$url);
die();

I tried something like this, but that doesn't work either:
Code: [Select]
$url="thepage.php";
header("Refresh: 0; url=".$url);
die();

This is really nasty problem...
How can I fix it?

I've got this sign in code:

Code: [Select]

[php]
<?php
include("conf.inc.php"); // Includes the db and form info.
if ($_SESSION['logged'] == 1) { // User is already logged in.
    $_SESSION['email'] = $email;
header("Location: main.php"); // Goes to main page.
exit(); // Stops the rest of the script.
} else {
if (!isset($_POST['submit'])) { // If the form HAS NOT been submitted.
echo "<td width=\"320\" height=\"50\" align=\"left\" valign=\"middle\"> </td>";
       echo "<td width=\"360\" height=\"50\" align=\"left\" valign=\"middle\">";
echo "<form name=\"form\" action=\"index.php\" method=\"POST\" style=\"margin-bottom:0;\">";
echo "<a href=\"signup.php\" class=\"bluelink\">Sign Me Up!</a>                  ";
echo "<a href=\"pwordhelp.php\" class=\"bluelink\" onMouseOver=\"window.name = 'main'\" onClick=\"return popup(this, 'notes')\">Forgot Password</a><br>";

echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">";
echo "</form>";
} else {    // If the form HAS been submitted
$email = form($_POST['email']);
$pword = md5($_POST['pword']); // Encrypts the password.

$q = mysql_query("SELECT * FROM `signin` WHERE email = '$email' AND pword = '$pword'") or die (mysql_error()); // mySQL query
$r = mysql_num_rows($q); // Checks to see if anything is in the db.

if (!$r) { // There is nothing in the db. The username/password do not match up.

echo "<td width=\"108\" height=\"50\" align=\"left\" valign=\"middle\"> </td>";
       echo "<td width=\"572\" height=\"50\" align=\"left\" valign=\"middle\">";
echo "<form name=\"form\" action=\"index.php\" method=\"POST\" style=\"margin-bottom:0;\">";
echo "                                                     <a href=\"signup.php\" class=\"bluelink\">Sign Me Up!</a>                 ";

echo "<font color=\"#FF0000\"><strong>Incorrect Email or Password.</strong></font>   ";
echo "<input type=\"text\" name=\"email\" size=\"17\" value=\"Email...\" style=\"color: #999999\" onfocus=\"if (this.value == 'Email...') {this.value=''; this.style.color='#000000'}\">    ";
echo "<input type=\"password\" name=\"pword\" size=\"17\" value=\"Password...\" style=\"color: #999999\" onfocus=\"if (this.value == 'Password...') {this.value=''; this.style.color='#000000';}\"> ";
echo "<input type=\"submit\" name=\"submit\" value=\"Submit\">";
echo "</form>";

} else {      // If the username/password is invalid

$_SESSION['logged'] = 1; // Sets the session.
$_SESSION['email'] = $email;
header("Location: main.php"); //   THIS IS LINE 111
exit(); // Stops the rest of the script.

}
}
}
?>
[/php]

And when I sign in with my user name and password, I get this warning message:

Warning: Cannot modify header information - headers already sent by (output started at /home/content/29/6879529/html/calhoun/index.php:9) in /home/content/29/6879529/html/calhoun/head1.inc.php on line 111

Can anyone help me out and tell me what I need to do to correct this? Thanks in advance for your help!

Header Problem

Hi guys,

I've got a header problem. I've read the header sticky post but i'm still not getting anywhere.

I am currently working on a registration form which loops though checking the data entered meets certain criteria by calling various functions (min length, max length, preg match, etc...), if anything returns 'false' then the form is reproduced with the error message of why it failed and what needs to be changed. If everything returned is 'true' then all day matches what is expected and the code then runs an 'insert' command. If the insert is successful then the code should forward the user to a new page displaying 'registration complete'.

However, the way I have written my code I am finding it near impossible to get the forward to be before anything is output to the browser therefore causing the header error. I have tried moving things around but i'm having no luck.

The error I am getting is:

Warning: Cannot modify header information - headers already sent by (output started at /websites/blahblahblah/register.php:6) in /websites/blahblahblah/register.php on line 77

The code there is relevant though as it is the code that make the connection to my DB.

Code: [Select]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<?php
// *** Connection - START ***
// connect to database
$connect = @mysql_connect("test", "test", "test") or die(mysql_error());

if (!$connect)
{
do_error("Could not connect to the server");
}

@mysql_select_db("test_db",$connect)or do_error("Could not connect to the database");
// *** Connection - END ***

// This file includes all of the check functions for the code to run through
include("check.php");

if ( $_SERVER['REQUEST_METHOD'] == 'POST' )
{
$data= new check($_POST);

$data->name('forename');
$data->name('surname');

if ( $data->pass == true )
{
// Now we have the required data in the correct format do the code required to complete registration

$forename=$data->input['forename'];
$surname=$data->input['surname'];

$query="INSERT INTO users ( forename, surname ) VALUES ('$forename' , '$surname' )";

if (mysql_query($query,$connect))
{
//echo "success";

// once data is inserted, go to complete page
header ("location: complete.php");
exit;
}
else
{
echo "Error: Please try again.";
}
}
}
else
{
$data= new check();
}
?>

What am I actually doing wrong and how can i possibly get the insert script higher up the code??

Thanks

the page below worked until i added the php include part to the top of the page and now i get the header error message for some of my web pages but i have fixed them all but this one.

How do i fix this because i can't move them to the top of the page just under the php include like i needed to do with the other pages because if i move them up it will put the forms at the top aswell.

<?php include("protect page file location"); ?>

Variable In Header Problem, Need Help!

What im trying to do is have the webpage forward the user to another page after they fill out something for a certain element in the database.

But the once I put the variable into a header for forwarding, the variable is thought to be a string instead of outputting its value it holds.

Heres my code....

$variable = "nextPage";

header('Location:webpage.php?id=$variable');

But whats its doing is sending the user to the url "webpage.php?id=$variable" instead of "webpage.php?id=nextPage"

What can I do to get the header to read the variable value and not the variable name?

All help is greatly appreciated!!!

Trying to create a simple login page (and my code is embarassingly disgraceful at this point).

In simple terms, I have start_session on three pages.

The first page asks for name, the second for password, the third welcomes user.

The second page contains

$name=$POST['name'];
$_SESSION['name']= $name;

When I access the page 2, the name is echoed with a greeting and request for password.

But after a password submission (whether correct or incorrect) the $name disappears.

I am at a loss for why it is not being refreshed or maintained in the session.

Any ideas for me?

Hi,

In the following code I'm using a combo box to select a relay and activate it. The code works but if I refresh the page, the last selected relay is activated again.

How can I reset the page to default to value '0' which has no relay control?

Refreshing Pages Without Visible Signs?

Similar Tutorials

View Content

Hi all.
I've seen on facebook and on some other sites where content refreshes without complete page reloads.
for example, right after posting a comment to a database, without any discernible page change, the comment appears somewhere on the page.
Is it using php vars and some auto refresh function, (how does it, without reloading appear then?)
I know that I am not very clear, but I need to know how to achieve this.

If you like to help me, please look at the attachments. They depict the process which I dearly want to know of.

Thank you for reading, and thanks in advance for trying to help.

Thauwa.

Sorry if this is in the incorrect section, but I suspect php activity here.
