Upload image and get URL

Gre se za Wordpress.

Do koraka, kjer uploadam sliko v media library gre ok, uporabljam to kodo:

vfunctions.php

function insertattachment($filehandler,$post_id,$setthumb='false') {

// check to make sure its a successful upload

if ($FILES[$file_handler]['error'] !== UPLOADERROK) _return_false();

requireonce(ABSPATH . "wp-admin" . '/includes/image.php');

requireonce(ABSPATH . "wp-admin" . '/includes/file.php');

require_once(ABSPATH . "wp-admin" . '/includes/media.php');

$attachid = mediahandleupload( $filehandler, $post_id );

if ($setthumb) updatepostmeta($postid,'thumbnailid',$attachid);

return $attach_id;

}

V samem fajlu, kjer je forma za upload pa tole:

if ($_FILES) {

foreach ($_FILES as $file => $array) {

    $newupload = insert_attachment($file,$pid);

}

};

Problem, ki me muči, je, da ne znam skodirati, da bi lahko dobil URL uploadane slike, ki bi ga potem v naslednji vrstici dodal kot custom field.

addpostmeta($post_information..........

(edit: tole je samo izsek tiste kode, imam vse potrebno in ostale podatke iz forme mi normalno naredi v post, samo slike ne).

Delam čisto narobe? Se da nekako dobiti url ali pa vsaj ID uploadane slike? Hvala.
