Question:
How can I make it display the users notes (from their note pad) in the index page? (I mean each member would be able to see his/her own note on the first page)
Answer:
<?php
global $SESS;
$member_id = $SESS->userdata['member_id'];
?>
{exp:query sql="SELECT notepad FROM exp_members WHERE member_id='<?php echo $member_id; ?>'"}
{notepad}
{/exp:query}
You need to allow php in the template and set it to input.
