BuddyPress.org

Hi I need yout help. I want to add a custom submit form in Buddypress. This form will insert input into database.
I have this form in my sidebar
`

`
And this php script inside the sidebar.php
`include_once(‘../../../../../wp-config.php’);
include_once(‘../../../../../wp-load.php’);
include_once(‘../../../../../wp-includes/wp-db.php’);
global $wpdb, $bp;
if($_POST[new_filter]””){
//

---

Store in DB

---

$sql_query =$wpdb->get_results( $wpdb->prepare(“INSERT INTO ai_bp_activity (type) VALUES (‘”.$_POST[new_filter].”‘)”));
}`
But its not working.
