related flexinodes by taxonomy term and with selected fields

Hi !

I need some help of a PHP coder to write a code that will display in a block the related flexinodes to the current one by taxonomy term and with the ability to choose which fields of the custom content type are displayed

On the website I've created, I've made a flexinode for discs chronicles whith many fields such as "name of the artist", "cover of the disc" etc. Each music style has its own subterm after the main term "discs"

So, when the current node belongs to the subterm "jazz" for e.g. I'd like to display in a block all the covers of the discs that belongs to this category with link to the full node.

I've found a code to display the "related nodes by term" which may be modified and I have a code to "display the last (x) flexinodes with custom layout".

The first one is...

<?php
if (arg(0) == 'node' && is_numeric(arg(1)) && is_null(arg(2))) {
  $nid = (int)arg(1);
  $terms = taxonomy_node_get_terms($nid);
  $output = "<ul>";
  foreach($terms as $term){
    $sql = "SELECT n.title, n.nid FROM {node} n INNER JOIN {term_node} tn ON n.nid = tn.nid WHERE tn.tid = $term->tid AND n.nid != $nid LIMIT 5";   
    $result = db_query(db_rewrite_sql($sql));
    if (db_num_rows($result)) {
      $output .="<li>$term->name</li><ul>";
      while ($anode = db_fetch_object($result)) {
        $output .= "<li>".l($anode->title, "node/$anode->nid")."</li>";
      }   
      $output.="</ul>";
    }
  }
  $output .= "</ul>";
  return $output;
}
?>

The second one is...

<?php
$flexi_id = "flexinode-1";
$list_no =8;
$sql = "SELECT node.type, node.nid FROM node WHERE node.type = '$flexi_id' ORDER BY created DESC LIMIT $list_no";
$result = db_query($sql);
while ($node = db_fetch_object($result)) {
  $nid = $node->nid;
//    print node_view(node_load(array('nid' => $node->nid)), 1);
  $data = node_load($nid);
?>

<a href="node/<?php print $data->nid ?>"><img src="<?php print file_create_url($data->flexinode_6->thumbpath) ?>" title="<?php print $data->flexinode_1 ?> :: <?php print $data->flexinode_3 ?>" /></a>
<?php
}
?>

I think a mix of them can be done to display in a block the related flexinodes to the current one by taxonomy term and with the ability to choose which fields of the custom content type are displayed but I need the help of a php "guru" to do it because I don't know PHP...

I hope you can help me ! :D

Thank you ;)
