$remote_addr not working :(

[fathermarcuss]

Hi! I'm new to php and I have this problem that's been bugging me the whole day.

I learned today that for some reason I cannot get the IP address of the visitors of my site because the $remote_addr function is not working. Is it possible that somebody hacked into my server and somehow disable the function for me?

I hope you guys can help me. I'm more of a designer than a programmer and this is giving me a headache. :(

maybe if you call the variable as $_SERVER['REMOTE_ADDR'] works

[fathermarcuss]

Thanks for the reply, Ponsho. I've tried that already. Actually, I already have the script working for 2 weeks which is why I find it suspicious that it just stopped working all of a sudden. I was thinking maybe somebody hacked and changed may PHP configurations somewhere so it stops from being able to get the remote IP of the visitors.  ???

it has to be $_SERVER['REMOTE_ADDR']; because it is a predefined variable. Are you sure it isnt working with that?

[fathermarcuss]

Thanks, [b]projectfear[/b]. Yes I'm sure it's not working. If you click on the link I gave above you will notice the the very same code I used is working on a different server. The script is working fine for two weeks that's why it beats that it stopped all of sudden and I didn't even changed anything on the script. Actually, any php scripts uploaded on that server can't get the remote IP of the visitors at all.  :'(

That's weird, check whats into $_SERVER array and post it here.

[code]
print_r($_SERVER);
[/code]

[fathermarcuss]

looks like it's working with that one, huh?

bummer! I really feel lost and stupid now  :D

[ponsho]

So its working now?

[wildteen88]

My Ip address shows over at freehostia but it doesnt on the other site.

Also no one can hack into your site and disable the REMOTE_ADDR variable. The server variables are defined via Apache or what ever webserver your webhosts uses.

Also REMOTE_ADDR is set to 203.87.177.110 for cjnavato.com. Does cjnavato.com have regsiter_globals enabled? You can chekc this by ruining the phpinfo function:
[code=php:0]<?php
phpinfo();
?>[/code]

[fathermarcuss]

the code you gave displayed my IP Adress but the actual script still can't get it.

Here the actual code i'm I have. It logs on the IP addresses of the visitors. It counts the number of times a particular IP visits and it adds a new one if it's a new IP address. The problem is, it now logs on a blank IP for ALL the visitors and counts all of them as one since the they're all "blank" IPs now. Does that make sense?

I really appreciate the help, guys. I'm a php virgin and my nose is bleeding now.  ;D



if (!session_is_registered("counted")){
$visitor_ipaddress = $_SERVER['REMOTE_ADDR'];
$visit_query = "SELECT * FROM visitors WHERE ip_address = '$REMOTE_ADDR'";
$result_query = mysql_query($visit_query);
if (!$rows=mysql_fetch_array($result_query))
{
$query = "INSERT INTO visitors (ip_address, visit_date, visit_time) " .
            "VALUES ('$visitor_ipaddress', current_date, current_time)";
mysql_query($query);
}
else
{
$new_visits = $visits + 1;
mysql_query("UPDATE visitors
SET
visit_date = current_date,
visit_time = current_time,
visits = (visits + 1)
WHERE
ip_address = '$REMOTE_ADDR'");
}
session_register("counted");
}

[ponsho]

Try replacing $REMOTE_ADDR with $visitor_ipaddress

[fathermarcuss]

thanks for clearing that up, [b]wildteen88[/b]. I'm really getting paranoid now coz it just stopped working all of a sudden.

here's what I got so i guess this the reason why it stopped? do you have any idea why it was turned off all of a sudden?
[b]register_globals Off Off[/b]

[b]ponsho,[/b] i'll try your suggestion. thanks a lot.

[wildteen88]

Most probably your host turned it off or they recently upgrade PHP. It i a good that regsiter globals is turned off. As it can cause security exploits in your code.

However ponsho's suggestion should work.

Always work with the superglobal arrays ( _GET, _POST, _SERVER, _COOKIE etc) regardles of the setting of register_globals if the host uses a PHP version greater than PHP4.2!

[ToonMariner]

no thats OK

ponsho has it...

In your script you declare $visitor_ipaddress = $_SERVER['REMOTE_ADDR']; but after that you refer to $REMOTE_ADDR which you have not defined previously - hence it will be empty

[fathermarcuss]

yes. it did work. thanks a lot guys.

thanks [b]ponsho[/b], [b]ProjectFear[/b] and to you [b]wildteen88[/b]. 

you guys will be rewarded in heaven ;D  ;D  ;D

Thanks to you too, ToonMariner.
