下一个和以前的图像mysql

Question

我想创建一个脚本，让您通过图像导航（下一个和上一个）。这是我到目前为止所做的，但它不起作用。

表：images

行：imageID

行：image_name =＆gt;这是建立一个查看图像的链接。

$currentid = $row['imageID'];
$query = "SELECT imageID as prev 
          FROM images WHERE imageID < '$currentid' 
          ORDER by imageID DESC LIMIT 1;";
$result = mysql_query($query) or die("Unable to read table : $query");
$list = array();
while ($image = mysql_fetch_assoc($result)) {
    $list[] = $image["imageID"];
}

$current_item = array_search($id1,$list);
$prev_link = $next_link = "";

if ($current_item > 0) {
    // do previous link with $list[$current_item - 1]
}
if ($current_item < sizeof($list)-1) {
    // do next link with $list[$current_item + 1]
}
