PHP header Function - Not Quite Working.

[mjjk91]

G'Day Everyone,

In the following code, i the user fills in their login information from the login.php script, then the page is redirected to the login_form.html script running login.php. It then goes into the "validate" case. Now, in this case, i wish to redirect the user to the page "loggedin.php", to show their login information, and to update my links bar. I have used the "header" function in the line-

header("Location: /loggedin.php");

, but for some reason, it will not re-direct me to this page. I know the rest of my script works, because when i type in the link loggedin.php into my browser, it comes up with all the information i need. So, any ideas why this header function is not working?

Here is my scripts

Cheers

login.php

<?php
include $_SERVER['DOCUMENT_ROOT'].

case "validate":
myheader("Validate!");
$validate = @mysql_query("SELECT * FROM members
WHERE username='{$_POST['username']}'
AND password = md5('{$_POST['password']}')
AND verified='1'");

if(mysql_num_rows($validate) == 1){
while($row = mysql_fetch_assoc($validate)){
$_SESSION['login'] = true;
$_SESSION['userid'] = $row['id'];
$_SESSION['first_name'] = $row['first_name'];
$_SESSION['last_name'] = $row['last_name'];
$_SESSION['email_address'] = $row['email_address'];

if($row['admin_access'] == 1){
$_SESSION['admin_access'] = true;
}

$login_time = mysql_query("UPDATE members
SET last_login=now()
WHERE id='{$row['id']}'");
}
header("Location: /loggedin.php");
} else {
myheader("Login Failed");

mjjk91,

Before this header() statement, there is a call to myheader("Validate!");. If this function outputs something, any later header() statement won't be effective (and PHP will show a warning.) You must execute header() before any other output (no embedded HTML, no echo statements...)

aprelium,

Thanks for your advice. I took out the myheader("Validate"); function, and its still not working. It still wont re-direct to the loggedin.php page, and its not coming up with any content, that is, no error messages, and no webpage content. So, any ideas on how i can rectify this?

Cheers

I'm very new to PHP but isn't the header function supose to be passed single quotes? header('Location: loggedin.php');

G'Day All,

Im still trying to work this problem out. I did some reading, and as people have told me, the header() function cannot be used after an output function, such as echo or print. Referring to the above code in the login.php file, if i was to put the line header("location: /loggedin.php"); right at the start of the file, directly under <?php, the page successfully redirects to the loggedin.php file, but none of the variables are passed from the login.php file. If i was to put the header() line after the include $_SERVER....... line, i get the same blank screen, and no re-direct. So, what does this mean?

Cheers everyone.
