I am getting the error like this:

Fatal error: Using $this when not in object context in /home/supeco/public_html/user.php on line 71

In user.php file's line#71, I see $this is used like this:
$hash = md5($this->secret.$HTTP_POST_VARS['username'])

It worked before my isp upgrade to php 5.

How should I change above $this usage so it will compatible with new php5??

Thanks.

Can you provide more code?

From the looks of it I think you are making a call to $this outside of the scope of an object.

Btw is this for a facebook app? Just wondering because the code looks familiar.

This is a part of php portal script from old days.

I did visit this thread (URL: http://www.webmaster-talk.com/php-fo...ot-object.html) too but still no idea how to fix mine

Here are a few lines.

$page_code = "user";
$page_name = LANG_USERDETAILS;
// Header file
include_once("$lib/themelib.php");
// Did the user filled the registration form?
if ((!$HTTP_POST_VARS['username']) || (!$HTTP_POST_VARS['password'])) {
// If not, go to registration form
header("Location: $root_url/register.php");
exit;
}
echo siteTheme ("header");
// If YES, start registration actions
// Hash code for confirmation mail
$hash = md5($this->secret.$HTTP_POST_VARS['username']);
// Connect database
dbconnect();
// Register user
$fullname = htmlspecialchars($FirstName)." ".htmlspecialchars($surname);
$sql = "INSERT INTO $t_users
(gender, name, surname, fullname, birthdate, country, address, state, city, zip, tel, job, email, list, hide_info, username,
password, hash, date, theme)
VALUES
('$gender', '".htmlspecialchars($FirstName)."', '".htmlspecialchars($surname)."', '$fullname', '$birthdate', '".htmlspecialchars($country)."', '".htmlspecialchars($address)."','".htmlspecialcha rs($state)."','".htmlspecialchars($city)."','".htm lspecialchars($zip)."','".htmlspecialchars($tel)." ', '".htmlspecialchars($job)."', '".htmlspecialchars($email)."', '$list','$hide_info',
'" . $HTTP_POST_VARS['username'] . "', '" . md5($HTTP_POST_VARS['password'])."', '$hash', now(), '$def_theme') ";
$result = @mysql_query($sql) or die ("Can not register user");

Thank you.

I can't tell from the code if you are using $this within an object. If you are not then $this doesn't have any meaning. The object model has been overhauled since PHP4 but generally most code is backwards compatible.

Again. Like the error says, make sure that you are not using $this outside of an object. If you give me more code I can help you out. Good luck

Per this forum rule, I can only send pm after the total 5 posts. I don't want to paste entire page here in the forum. I really like to know how to alter the $this usage like some people explain in this topic (URL: http://www.webmaster-talk.com/php-fo...ot-object.html). I really don't know about programming. I only see the $this once in the script like I posted above. Only that line uses it.

Thank you.

Can you send me message so I may be can reply it back to you with the script. This is very inconvenient. I can't still send message to anyone. I don't know if I need to do the pay membership. No way to contact the webmaster too. Can someone read my message above and help me, please?

I've just sent the pm. Thanks.

NOTE:
$HTTP_POST_VARS is old use $_POST instead.

Also try concatanating the two vars '$md5 = $this->secret.$_POST['username']'
$hash = md5($md5)

I modified the script as you advised but still giving me the same errors.

Does $this->secret hold any info. Try echo it out and see. Try same with $HTTP_POST_VARS['username'];

Also try adding error_reporting (E^ALL); at the top of your script.

Ibbo

Thank you for your help.

I followed your advice, I echo out $this->secret and just used $HTTP_POST_VARS['username'];

The script is now almost working for registration but when user log back in to the site, the new error is displayed as:

Warning: Cannot modify header information - headers already sent by (output started at /home/supeco/public_html/library/themelib.php:565) in /home/supeco/public_html/user.php on line 13

Is it http issue? Can you help me fix it, please?

Thank you.

Make sure you're not generating any output before you use the header function. If you echo or print anything you won't be able to forward to a new location. Most likely you've just left your echo $this->secret in your code, if you remove it that should fix your problem.

Maybe you out from an Object. $this refer to an object. If you out of an object or you dont sure, make:
print_r($this);
And watch what is $this
