Help with allowing User to change set pricing

The php web video script that I’m using works successfully where Users can edit the price of their uploaded video (the minimum price is set in the admin panel for all uploaded videos). But, I am looking for assistance with modifying so that just one user/uploader (named “Admin”) can set a price lower than the minimum. Here is the edit-video.php file code:

[code]

<?php
if (IS_LOGGED == false) {
header(“Location: ” . PT_Link(‘login’));
exit();
}
if (empty($_GET[‘id’])) {
header(“Location: ” . PT_Link(‘login’));
exit();
}
$id = PT_Secure($_GET[‘id’]);
$video = $db->where(‘id’, $id)->getOne(T_VIDEOS);
if (empty($video)) {
header(“Location: ” . PT_Link(‘login’));
exit();
}
if (!PT_IsAdmin()) {
if (empty($db->where(‘id’, $id)->where(‘user_id’, $user->id)->getValue(T_VIDEOS, ‘count(*)’))) {
header(“Location: ” . PT_Link(‘login’));
exit();
}
}
$video = PT_GetVideoByID($video, 0, 0, 0);
$pt->video = $video;
$pt->page = ‘edit-video’;
$pt->title = $lang->edit_video . ‘ | ‘ . $pt->config->title;
$pt->description = $pt->config->description;
$pt->keyword = $pt->config->keyword;

$min_price=$config[‘video_play_price’];
$temp_price = $videos[‘video_play_price’];
if ($temp_price<$min_price) { $temp_price = $min_price;}

$pt->content = PT_LoadPage(‘edit-video/content’, array(
‘ID’ => $video->id,
‘USER_DATA’ => $video->owner,
‘THUMBNAIL’ => $video->thumbnail,
‘URL’ => $video->url,
‘TITLE’ => $video->title,
‘DESC’ => br2nl($video->edit_description),
‘DESC_2’ => $video->markup_description,
‘VIEWS’ => $video->views,
‘TIME’ => $video->time_ago,
‘TAGS’ => $video->tags,
‘video_play_price_user’ => number_format( $video->video_play_price < $config[‘video_play_price’] ? $config[‘video_play_price’] : $video->video_play_price)
));

[/code]

any assistance with this modification is appreciated
