Indsætter ikke i DB

Problem 2 med dette script, når jeg trykker på Tilføj Link, sker der ikke andet end at siden vises i et nyt vindue, selve siden med formularen skifter ikke, og der gemmes intet i databasen..

Index.php med formular

<?php
  include($DOCUMENT_ROOT.'/php/start.php');
  require($_SERVER["DOCUMENT_ROOT"].'/php/links_boot.php');
  include($_SERVER["DOCUMENT_ROOT"].'/php/links_functions.php');

// linkstrenge til de tre funktioner.
$linkshowtop = "<a href=\"$thisfile\">Top links</a> &nbsp; ";
$linkshowall = "<a href=\"$thisfile?show=all\">Vis alle</a> &nbsp; ";
$linkadd = "<a href=\"$thisfile?addurl=yes\">Tilføj URL</a>";

if (strtolower($show) == "all") {
  $where = "";
} else {
  $where = " having point >= 0";
}

$count = query("select sum(hits) as cnt from links");
$hitcount = $count[0]->cnt;

$result = query("select id,title,date,rating,hits,url,(hits*rating-(to_days(curdate())-to_days(date))) as point ".
                "from links$where order by title desc, point DESC");

page_start("");

if (!isset($addurl)) {

Addlink.php

<?php

Links_boot.php

<?php

og sidst, links_functions.php

<?php

          "<img src=\"/rate/cleardot.gif\" alt=\"----------------------\" width=1 height=1></td></tr></table>\n";

  return $temp;
}

function page_start() {

  echo "<center><p><b>$title</b></p>\n";
}

function page_end() {
  echo "</center>\n";
}
?>

Koderne er meget gamle, dvs. de fungerede en gang, kan de mon være 'for' gamle?

Kan de opdateres så de fungerer bedre?
