如何在另一页获取信息后插入数据库

Question

i try to get information in another page which works fine, the only facing problem is that i can't insert in database the information i get, for example:

This is the link i use which works fine.

index.php

<a href="http://example.com/q.php?url= '. $row['url'] .'&title='. $row['title'] .'" target="_blank">Edit</a>

q.php

    $ip_address = $_SERVER['REMOTE_ADDR']; // This is working fine.
    $title = $_GET['title']; 

mysql_query("insert into test_insert (title,ip) values('$title','$ip_address')")
            or die(mysql_error());

$title = $_GET['title']; // Not working
// If i delete this row above and replace with below it works.
$title = 'test';         // This is working and puts (test) in row title

I can't understand why i can show the information in q.php with:

<?php echo $_GET['title']; ?>

And can't insert it in database, what is wrong with this ?

Any help is welcome.

Thanks in advance.
