Adding IP to a PHP Form

[Website]

How can i add the visitors ip to this php email form?

<?php

$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));

session_start();
if( ($_SESSION['security_code']==$_POST['security_code']) && (!empty($_POST['security_code'])) ) { 
mail("admin@site.com","Title of the Form","Form content:

Name and last name: " . $_POST['field_1'] . " 
Country: " . $_POST['field_2'] . " 
 


");

include("confirm.html");
}
else {
echo "Invalid Captcha String.";
}

?>

I know add can just add this

$ip=@$REMOTE_ADDR;
echo "<b>IP Address= $ip</b>";

But where am i gonna add it to and how can i make the form email it with the other content?
This is the processor.php of the email form which is embedded in an html page.

Here is the code

PHP Code:

$ip = $_SERVER['REMOTE_ADDR'];

//Then add that to the mail() 

mail("admin@site.com","Title of the Form","Form content:
Name and last name: " . $_POST['field_1'] . " 
Country: " . $_POST['field_2'] . 
" IP : $ip" //<-----
);

Nice. Thank you.
Do you think we can also add like browser, useragent, computername, location etc. info too?
I mean like all the info we can get from the submitter.

[Website]

As the previous example...
I put this code
$browser = $_SERVER['HTTP_USER_AGENT'];
right under the ip get code.
and this code
"User Agent: $browser" in the mail code. Right next to ip.

But now it doesnt even send any email. And doesnt give any error either.

Well i dont mean to flood but i cant delete my old message. So i have to write another one.
------------------------
I think i found a very nice code for this problem. It gives you full featured computer info of a submitter.

Can anybody tell me how can i add this to my php email processer form?
Example can be seen at
http://techpatterns.com/downloads/ph..._detection.php

[scrapemaster]

Why are you making your life complicated? Just use PHP in order to get users info in the form.

PHP Code:

<?php
$to      = 'nobody@example.com';
$subject = 'the subject';

$ip = $_SERVER['REMOTE_ADDR'];
$browser = $_SERVER['HTTP_USER_AGENT'];

// here add the info you need from customer as a different variables $ip, $browser and so on and take the info from the form

$message="User ip: ".$ip." User browser ".$browser;

$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
?>

You da man. Thank you.

[Website]

Well now what do you put between the values when you want to add more info in message code?

$message="User ip: ".$ip." User browser ".$browser;

say i want to add these inquiries also...
$HTTP_COOKIE_VARS["users_resolution"]
$_SERVER['HTTP_REFERER']
$_ENV[COMPUTERNAME]

$HTTP_COOKIE_VARS["users_resolution"]
$_SERVER['HTTP_REFERER']
$_ENV[COMPUTERNAME]

first get the values in new variables

$resolution=$HTTP_COOKIE_VARS["users_resolution"];
$pcname=$_ENV[COMPUTERNAME];
$serv=$_SERVER['HTTP_REFERER'] ;

and the have to include it in the mail

$message="User ip: ".$ip." User browser ".$browser." Resolution ".$resolution." Computer name ".$pcname." Server ".$serv;

[Website]

Perfect. What informations i can get from them? Because i couldnt get the resolution. This is a form which is embedded in an html page.

[JohnnyS]

Please note that $_SERVER['HTTP_USER_AGENT'] sometimes does not work because some browsers does not send it's info. You may encounter a PHP notice from it..

[Website]

Then what is the best code to get the user agent?

[JohnnyS]

JavaScript would do, you can put it inside a hidden field before submitting your form.

<input type="hidden" name="user_agent" id="ua" />

<script type="text/javascript">
document.getElementByid('ua').value = navigator.userAgent;
</script>

[Website]

I cant use java... it has to be php.

[AdrianC]

Its javascript, not java and you use it to transfer data to php...

[Website]

So what is my php code and how can i put it in there?

[AdrianC]

You're going to want to use something like this:

<form action="myPhpFile.php" method="post">
<input type="hidden" name="user_agent" id="ua" />
</form>

Then you grab the data in php using

$_POST['user_agent']

[Website]

This is getting too complicated. I dont even know where to put these codes in my email form.

Its ok. Thx anyways.
