BuddyPress.org

Hello,

I use Buddypress for my college. Every semester the members (students) were automatically joined to the groups (courses) that they took using Groups-O-Matic Plugin. It is running as expected for now.
What I want is, when the semester will be over, I want to remove all member from the groups (also the group admin) and reset their certain page of profile field that contains the list of group names (myurl…./profile/edit/group/3).
So the members are forced to complete their profile field again and automatically joined the relevant groups as they complete their profile field for their next semester.

I think that it is related to functions.php and header.php.

Buddypress 1.8.1, WordPress 3.7.1

This is what I have written in functions.php:

/** Reset MatKul */
if ( current_user_can( ‘administrator’ ) )
{ add_action(‘admin_bar_menu’, ‘admin_bar_reset_matkul’, 100); }

function admin_bar_reset_matkul($admin_bar){
$admin_bar->add_menu( array(
‘id’ => ‘reset-matkul’,
‘title’ => ‘Reset MatKul’,
‘href’ => ‘?reset_matkul=true’,
‘meta’ => array(
‘title’ => __(‘Reset Mata Kuliah’),
//’onclick’ => ”,
),
));

}

function reset_matkul() {
if (current_user_can(‘administrator’))
{
reset_matkul_111(); reset_matkul_222();
}
else
{ echo “<script>alert(‘Access Deny’);</script>”; }
}
function reset_matkul_111() {
global $wpdb;
$wpdb->query(” DELETE FROM wp_bp_xprofile_data WHERE field_id = ‘3’ and user_id <> ‘1’ “);
echo “<script>alert(‘Reset Mata Kuliah Selesai’);</script>”;
}
function reset_matkul_222() {
global $wpdb;
$wpdb->query(” DELETE FROM wp_bp_groups_members WHERE user_id <> ‘1’ “);
echo “<script>alert(‘Reset Group Selesai’);</script>”;
}

** I also make a button on my backend admin bar on header.php for this function.

Could you guys please help?

Big thanks!
