Simpelt script til phpbb forum template

X Jeg skal have indsat noget kode i en phpbb forum template der skal kunne følgende:

hvis bruger tilmeldt forumet indenfor sidste x antal dage (eventuelt bare siden x dato)
så script1
ellers
script2

script1 og 2 er noget kode jeg allerede har...

Formålet med denne post er at få en "skabelon" som jeg så selv kan arbejde videre på...jeg er desværre newbe.

eksempel på template: (forestiller mig at script skal indsættes efter første table linie)

<table width="100%" cellspacing="0" cellpadding="2" border="0" align="center">
  <tr>
    <td align="left" valign="bottom"><span class="gensmall">
    <!-- BEGIN switch_user_logged_in -->
    {LAST_VISIT_DATE}<br />
    <!-- END switch_user_logged_in -->
    {CURRENT_TIME}<br /></span><span class="nav"><a href="{U_INDEX}" class="nav">{L_INDEX}</a></span></td>
    <td align="right" valign="bottom" class="gensmall">
        <!-- BEGIN switch_user_logged_in -->
        <a href="{U_SEARCH_NEW}" class="gensmall">{L_SEARCH_NEW}</a><br /><a href="{U_SEARCH_SELF}" class="gensmall">{L_SEARCH_SELF}</a><br />
        <!-- END switch_user_logged_in -->
        <a href="{U_SEARCH_UNANSWERED}" class="gensmall">{L_SEARCH_UNANSWERED}</a></td>
  </tr>
</table>

<table width="100%" cellpadding="2" cellspacing="1" border="0" class="forumline">
  <tr>
    <th colspan="2" class="thCornerL" height="25" nowrap="nowrap">&nbsp;{L_FORUM}&nbsp;</th>
    <th width="50" class="thTop" nowrap="nowrap">&nbsp;{L_TOPICS}&nbsp;</th>
    <th width="50" class="thTop" nowrap="nowrap">&nbsp;{L_POSTS}&nbsp;</th>
    <th class="thCornerR" nowrap="nowrap">&nbsp;{L_LASTPOST}&nbsp;</th>
  </tr>
  <!-- BEGIN catrow -->
  <tr>
    <td class="catLeft" colspan="2" height="28"><span class="cattitle"><a href="{catrow.U_VIEWCAT}" class="cattitle">{catrow.CAT_DESC}</a></span></td>
    <td class="rowpic" colspan="3" align="right">&nbsp;</td>
  </tr>
  <!-- BEGIN forumrow -->
  <tr>
    <td class="row1" align="center" valign="middle" height="50"><img src="{catrow.forumrow.FORUM_FOLDER_IMG}" width="46" height="25" alt="{catrow.forumrow.L_FORUM_FOLDER_ALT}" title="{catrow.forumrow.L_FORUM_FOLDER_ALT}" /></td>
    <td class="row1" width="100%" height="50"><span class="forumlink"> <a href="{catrow.forumrow.U_VIEWFORUM}" class="forumlink">{catrow.forumrow.FORUM_NAME}</a><br />
      </span> <span class="genmed">{catrow.forumrow.FORUM_DESC}<br />
      </span><span class="gensmall">{catrow.forumrow.L_MODERATOR} {catrow.forumrow.MODERATORS}</span></td>
    <td class="row2" align="center" valign="middle" height="50"><span class="gensmall">{catrow.forumrow.TOPICS}</span></td>
    <td class="row2" align="center" valign="middle" height="50"><span class="gensmall">{catrow.forumrow.POSTS}</span></td>
    <td class="row2" align="center" valign="middle" height="50" nowrap="nowrap"> <span class="gensmall">{catrow.forumrow.LAST_POST}</span></td>
  </tr>
  <!-- END forumrow -->
  <!-- END catrow -->
</table>
