Why not work sending message in DD with JomSocial

YESSS!! I Fix this. That works:

// core pms notifications
if($profileman =='js')
{
$db = JFactory::getDBO();
$q ="INSERT INTO #__community_msg (`from`,`deleted`,`from_name`,`posted_on`,`subject`,`body`)
VALUES
('0', '0' , 'System' , '".date('Y-m-d H:i:s')."' ,'".$db->escape($subject)."' , '". '{"content":"' . str_replace('"', '\"', $db->escape($body))."\"}' ) ";
$db->setQuery($q);
$db->execute();
$msg_id = $db->insertid();
$q ="UPDATE #__community_msg SET `parent`=".$msg_id." WHERE `id` = ".$msg_id;
$db->setQuery($q);
$db->execute();
$ids = array( $my->id , $partner->id );
for($i=0;$i<count($ids);$i++)
{
$q = "INSERT INTO #__community_msg_recepient
(`msg_id` , `msg_parent` , `msg_from` , `to` , `bcc` , `is_read` , `deleted`)
VALUES
('".$msg_id."' , '".$msg_id."' , '0' , '".$ids[$i]."', '0' , '0' , '0' )";
$db->setQuery($q);
$db->execute();
}
}
elseif($profileman =='es')
{
//to do
}

Well done
1. couldn't the str_replace function be replcad by 'addslashes' function?
2. Are the profile links rendered correctly ?

1. I not a guru of PHP..
2. Opsss... yes, link is broken ((
