1. error log (130% the weight of the access_log)
PHP Notice: Undefined index: HTTP_REFERER in /home/virtual/site3/fst/
var/www/html/cpm_cost.php on line 8
[client 83.155.157.238]
As said earlier, the referrer can be empty, which causes this message.
Before you want to use it (if you want to use it at all, because it's
completely unreliable), check with isset() or empty() if it exists:
if (isset($_SERVER['HTTP_REFERER'])) {
...
}
>PHP Notice: Undefined index: cpm9 in /home/virtual/site3/fst/var/www/
html/cpm_cost.php on line 45
[client 83.155.157.238]
Same thing with the cookie value. Obviously it's not set. isset() or
empty() should be used more often.
>PHP Notice: Undefined variable: redirect in /home/virtual/site3/fst/
var/www/html/cpm_cost.php on line 106
This code:
>line 106 :
$redirect .='Location:'.$uploadpath;
tries to append a value to $redirect, which is equivalent to
$redirect = $redirect.'Location:'.$uploadpath;
If $redirect doesn't exist yet, you'll get the notice. You could simply
remove the dot to make this an assignment rather than an appending:
$redirect = 'Location:'.$uploadpath;
or
$redirect = "Location: $uploadpath";
Also note that $uploadpath _must_ contain an absolute URL, including the
scheme (http:) and host name. This is required by the HTTP spec.
><?
This should be <?php, since short open tags are unreliable and can be
disabled on the server.
>error_reporting(0);
include_once("...");
header("P3P: policyref=\"http://www.gle-mosco.com/adveruser/p3p.xml
\",CP=\"NON DSP COR CURa PSA PSD OUR BUS NAV STA\"");
$http_ref= $_SERVER['HTTP_REFERER'];
$affsite=$_REQUEST['affsite'];
$banner=$_REQUEST['banner'];
$_REQUEST is usually bad as well, since you don't know where the data is
actually coming from. If you expect a URL parameter, use $_GET.
I didn't go through the rest of the code.
