Using "return <<<EOF" inside "if...else"

[mrbaseball34]

I'm trying to modify my Invision Board to have alternating row colors.

I have this code:

function RenderRow($Data) {
global $ibforums;
return <<<EOF
    <!-- Begin Topic Entry {$Data['tid']} -->
    <tr>
      <td align='center' class='forum2'>{$Data['folder_img']}</td>
      <td align='center' class='forum1'>{$Data['topic_icon']}</td>
      <td class='forum2'>
        <table width='100%' border='0' cellspacing='0' cellpadding='0'>
	  <tr>
            <td valign='middle'>{$Data['go_new_post']}</td>
            <td width='100%'><span class='desc'><LONG SPAN SNIPPED>
</span></td>
          </tr>
        </table>
        <span class='desc'>{$Data['description']}</span>
      </td>
      <td align='center' class='forum2'>{$Data['starter']}</td>
      <td align='center' class='forum1'>{$Data['posts']}</td>
      <td align='center' class='forum2'>{$Data['views']}</td>
      <td class='forum1'><span class='desc'><LONG SPAN SNIPPED></span>
</td>

</tr>
<!-- End Topic Entry {$Data['tid']} -->
EOF;
}

and need to alternate between td.forum1 and td.forum2.

I've tried this and it doesn't work:

function RenderRow($Data, $counter) {
  global $ibforums;
  if ($counter%2 == 0) {
    return <<<EOF
    <!-- Begin Topic Entry {$Data['tid']} -->
    <tr>
      <td align='center' class='forum2'>{$Data['folder_img']}</td>
      <td align='center' class='forum2'>{$Data['topic_icon']}</td>
      <td class='forum2'>
        <table width='100%' border='0' cellspacing='0' cellpadding='0'>
	  <tr>
            <td valign='middle'>{$Data['go_new_post']}</td>
            <td width='100%'><span class='desc'><LONG SPAN SNIPPED>
</span></td>
          </tr>
        </table>
        <span class='desc'>{$Data['description']}</span>
      </td>
      <td align='center' class='forum2'>{$Data['starter']}</td>
      <td align='center' class='forum2'>{$Data['posts']}</td>
      <td align='center' class='forum2'>{$Data['views']}</td>
      <td class='forum2'><span class='desc'><LONG SPAN SNIPPED></span>
</td>
    </tr>
    <!-- End Topic Entry {$Data['tid']} -->
    EOF;
  } else {
    return <<<EOF
    <!-- Begin Topic Entry {$Data['tid']} -->
    <tr>
      <td align='center' class='forum1'>{$Data['folder_img']}</td>
      <td align='center' class='forum1'>{$Data['topic_icon']}</td>
      <td class='forum1'>
        <table width='100%' border='0' cellspacing='0' cellpadding='0'>
	  <tr>
            <td valign='middle'>{$Data['go_new_post']}</td>
            <td width='100%'><span class='desc'><LONG SPAN SNIPPED>
</span></td>
          </tr>
        </table>
        <span class='desc'>{$Data['description']}</span>
      </td>
      <td align='center' class='forum1'>{$Data['starter']}</td>
      <td align='center' class='forum1'>{$Data['posts']}</td>
      <td align='center' class='forum1'>{$Data['views']}</td>
      <td class='forum1'><span class='desc'><LONG SPAN SNIPPED></span>
</td>
    </tr>
    <!-- End Topic Entry {$Data['tid']} -->
    EOF;
  }
}

How can I do that with the <<<EOF and passing a variable $counter in
the function call?

Read the warning note in the documentation of the heredoc operator:

Thanks, I didn't know what that was called (heredoc) to look for it.

I think I have it now, however...
