strange variables

[Sebastian]

ok.. im working on a hack but have 1 problem..

i want to get the username of the parent post the child belong to.. so i did this:

in showthread on $getpostids query while loop i did:

PHP Code:

$parentpost["$post[postid]"] = $post['postusername']; 

then on $post while loop:

PHP Code:

$post['parentuname'] = $parentpost["$post[parentid]"]; 

so i use $post[parentuname] on postbit works just fine.. BUT it only appears for admins.. wtf??

can anyone find how is this possible when i am not even using a condition for admin?
