not updating database

[Glenskie]

ok it updates the posts table , but not the notifications table , helP!

<?php include("../includes.php");
$session =$logOptions_id;
if($session)
{
$id = $_POST['id'];
if(!$id)
{
$id = $session;	
}
$post = mysql_real_escape_string($_POST['post']);
$date = mktime();





$action_type = 0;



mysql_query("INSERT INTO posts SET to_id='$id',from_id='$session',post='$post',type='$action_type',date='$date'");
$post_id = mysql_insert_id();

$query = mysql_query("SELECT id,to_id,from_id,post,type,state,date FROM posts WHERE id='$post_id' AND state='0' ORDER BY id DESC LIMIT 15");	
print posts($query, "newPost");

if($id!=$session)
{
mysql_query("INSERT INTO notifications SET user_id='$id', from_id='$session', post_id='$post_id', action_type='$action_type', date='$date'");
}

}
?>

then either $id == $session or your query is failing for some reason. If you suspect the ladder, use mysql_query to debug the query.
