前ノード/全ノードのサムネイルをフルノードで表示

Question

これを理解して動作させようとしてきましたが、私はプログラマーではないので、コーディングに関する知識が限られているデザイナーだけですこの壁の壁。

私は自分のフォトギャラリーを作っています。リンクされたサムネイルとして2つ前または次の画像を表示したいと思います。私は、このスクリプトが動作し、テキストのリンクを表示するが、私のニーズにそれを適応させる方法を知らない。

template.php

<?php 
function dad_prev_next($current_node = NULL, $op = 'p') { 
    if ($op == 'p') { 
     $sql_op = '<'; 
     $order = 'DESC'; 
    } elseif ($op == 'n') { 
     $sql_op = '>'; 
     $order = 'ASC'; 
    } else { 
     return NULL; 
    } 

    $output = NULL; 

    $sql = "SELECT n.nid, n.title 
      FROM {node} n 
      WHERE n.nid $sql_op :nid 
      AND type IN ('photos') 
      AND status = 1 
      ORDER BY nid $order 
      LIMIT 1"; 
    $result = db_query($sql, array(':nid' => $current_node -> nid)); 
    foreach ($result as $data) { 
    } 
    if (isset($data)) {    


     if ($op == 'n')    
      return l("Next", "node/$data->nid", array('html' => TRUE)); 
     else if ($op == 'p') 
      return l("Previous", "node/$data->nid", array('html' => TRUE)); 
    } 
} 
?> 

<?php print dad_prev_next($node,'p') . "/" . dad_prev_next($node,'n'); ?>
