HTTP Authentication

yogadt

Hi,

I am new to php.

I want to get the username and password using
headers and get connected to mysql database using
mysql_connect function. If the connection fails, once again the header has to get the username and password. But I get the following error , when I tried to call the user defined function which has header function

Warning: Cannot add header information - headers already sent by (output started at
header.inc.php:217) in header.inc.php on line 201

Please help me to resolve this problem or point where I can get more info about this.

Thanks in advance.

What this script is telling you is that it has sent some type of HTML or some other type of header to your browser and you cant send it again. Get rid of any tags or anything like that. Only use the php script then if it fails or goes through start your output to browser or redirect. There is actually a warning about this in the php manual:

http://www.php.net/manual/en/function.header.php

Hope that helps.

<?
if($error==true) {
header("location:/sub1/sub2/subn..");
exit;
}else {
process...
}
?>

start your php server-side at the top before any html tags..

Good Luck!

Hi,

if ($connect)
{
$dbh=mysql_connect($host,$user,$password) ;
if (!dbh)
{
// unset the user &password and $PHP_AUTH_USER & PHP_AUTH_PASSWORD
// Call the function which will send headers

}
}
?>

This is what I have done. I got the username and password using header function and tried to connect to the mysql. If the username and password is invalid then I have to get the values again. But it doesn't works.

Please help.

Thanks in advance,

Hmm... $connect is undefined unless you're
leaving out some crucial part of the code.
And you're probably missing a $ in the next if.

Using the 'basic' authentication scheme isn't
something I'd recommend, but if you want an
example of how to do it in PHP you could e.g.
take a look at the phpMyAdmin source.
