Views Archive Drill Down (Year//Month/Day) Block?

It's not exactly what you want, but I'd start looking at how the Archive module does things. Conceptually you and they are working along the same lines.

Are you looking to implement this in a page or a block? The title says block but then you refer to a page later on.

Hello,
I was looking for this solution too. It seems like a common need. So I thought I would post the somewhat hackish solution I came up with (I am still a drupal newB, so it is likely that this isn't a great approach):

1. Copy the archive view that ships with drupal, as a starting point
2. Open the block display
3. In the arguments section:

• add the arguments 1. Node: Created Year; 2. Node: Month.
• choose Summary, sorted descending
• add the style list to both
• make sure the Year argument is before the Month argument
• Delete the Node: Created Year + Month

4. give your block a machine name (e.g., news_archive)
5. Add the following to your template's template.php

function yourtheme_preprocess_block(&$vars) {

/*
* get years from [your_view] and pass as parameter to [your_archive] block
* to use later to create accordion of links
* you have to render the view in the block's preprocess to be able
* to get to the actual years, and not just have the view field metadata
*/

  if($vars['block']->delta == 'your_archive_view_display_name') {
    $viewName = 'your_archive_view';
    $display_id = 'your_archive_view_display_name';
    $view = views_get_view($viewName);
    $view->set_display($display_id);
    $view->render();

    $years = array();
    foreach ($view->result as $result) {
      $year = $result->created_year;
      if (in_array((string)$year, $years, TRUE) == FALSE) {
        array_push($years, $result->created_year);
      }
    }

  $vars['block']->archive_years = $years;

  }
}

6. Then add something along the lines of the following in tpl file for that block. I am using the JQuery UI Accordion function to create the drop-down lists of months, after someone has clicked on a year. Though another UI approach I'm sure would work just as well.

<div id="archive_accordion" class="ui-accordion">

  <?php
  //will use the same view info as in the preprocess
  $viewName = 'your_archive_view';
  $display_id = 'your_block_name';
  $years = $block->archive_years; //get the passed parameter containing the array of years

  foreach ( $years as $year) {
    print '<h3><a href="#">'. $year . '</a></h3>';
    print '<div>';
    // but this time you will embed an archive view for each year in the block. 
    //i.e., actually print out a view with each year that was in the passed array
    print views_embed_view($viewName, $display_id, $year);
    print '</div>';
  }
?>

</div>

Conceivably, you could just add the day argument, and add get the month variables in the preprocess, and repeat to be able to drill another level for the Created Day.

I followed the instructions but I'm getting this error:

Notice: Undefined variable: block in include() (line 6 of /Applications/MAMP/htdocs/mysite/sites/all/themes/mytheme/views-view--my-archive-view--block-1.tpl.php).
