从表格中将IP地址插入表格

Question

When my PHP form is submitted I am trying to get the end users IP address and insert it into the database table with the record.

My form posts to another php page.:

<form name="contact_form" method="post" action="http://x.com/promotions/boston_mailer.php">
<table border="0"> ...etc...

I set my boston_mailer.php to grab the IP address:

$ipaddress = $_SERVER['REMOTE_ADDR'];   
$sql = "INSERT INTO 
            ucm_signup 
            ( fname, lname, email, phone, iama, buyfrom, ipaddress )
        VALUES
            ( '$_POST[fname]', '$_POST[lname]', '$_POST[mail]', '$_POST[phone]',
              '$_POST[iama]', '$_POST[buyfrom]', '$_SERVER[$ipaddress]')";

My DB table (phpMyAdmin) has a column named "ipaddress" and is set as VARCHAR with 30 size.

When I submit the form the IP address is nil. "". What am I missing? Do I need to put something in my form.php page? Thank you

Instead of $_SERVER[$ipaddress] on your query just send $ipaddress , because $_SERVER[$ipaddress] is undefined.

The right way...

$ipaddress = $_SERVER['REMOTE_ADDR'];   
$sql = "INSERT INTO 
            ucm_signup 
            ( fname, lname, email, phone, iama, buyfrom, ipaddress )
        VALUES
            ( '$_POST[fname]', '$_POST[lname]', '$_POST[mail]', '$_POST[phone]',
              '$_POST[iama]', '$_POST[buyfrom]', '$ipaddress')";
