Gravity Forms Submit data to external database - wordpress

Question

I am having trouble with a form I created with gravityforms. This form's purpose is to grab the form's input, encrypt the password and write that data directly to a database. I have verified the database's username, password and IP.
The problem is that the form does submit, I can see the entry, but no data is written to the database. it just stucks with a loading circle next to the submit button.
Here is the code I use inside my functions.php file:
add_action("gform_after_submission_1", "create_account", 10, 2);
function create_account($entry, $form) {
define('mySQL_hostname', '<ip>'); //database IP
define('mySQL_database', '<database name>'); //database name
define('mySQL_username', '<user>'); //database user
define('mySQL_password', '<pass>'); //database password
$db_link = mysql_pconnect( mySQL_hostname, mySQL_username, mySQL_password )
or die( 'Error connecting to mysql<br><br>'.mysql_error() );
function l2j_encrypt($password) {
return base64_encode(pack("H*", sha1(utf8_encode($password))));
}
$str = l2j_encrypt($entry["2"]);
$user = $entry["1"];
$currdate = date('Y-m-d H:i:s');
$email = $entry["3"];
$db_select = mysql_select_db( mySQL_database, $db_link )
or die( 'Error connecting to Database<br><br>'.mysql_error() );
if ($user == '') { print'Incorrect UserID'; mysql_close(); }
else {
$db_add = mysql_query( "INSERT INTO `accounts` VALUES ('$user', '$str', '0', '0', '', '1', '$email', '$currate')" )
or die( 'Error: '.mysql_error() );
}
mysql_close();
}
Also, what's the deal with the 10,2 parameters? I couldn't find anything that explains those...
Note that the above code, when in a separate php file, combined with an html form, work just fine....
Any help?
P.S: Can anyone help me build a function that submit this data to an external php file? In case I cannot make this work....

After playing around with gravity for a bit, i managed to find a workaround.
add_action("gform_after_submission_6", "set_page_log", 10, 2);
function set_page_log($entry, $form){
function post_to_url($url, $data) {
$fields = '';
foreach($data as $key => $value) {
$fields .= $key . '=' . $value . '&';
}
rtrim($fields, '&');
$post = curl_init();
curl_setopt($post, CURLOPT_URL, $url);
curl_setopt($post, CURLOPT_POST, count($data));
curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
curl_setopt($post, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($post);
curl_close($post);
}
if($form["id"] == 6){//checking if the correct form is being used or not (optional)
$data = array(
"item1" => $entry["2"],
"item2" => $entry["5"],
"item3" => $entry["4"]
);
post_to_url("http://www.example.com/post_data.php", $data);
//you can make changes to the data passed by gravity at the above url
}
}
I have tested the above code with Gravity 1.6 and WP 3.5.1.
