Thumbnail Hover - main frame ignores views tpl override

It's related, and I did some digging in views threads, but I believe the main issue is in Views Slideshow. Normally views output can be overridden by using views-view-fields--viewname.tpl.php, however, Views Slideshow Main Frame somehow ignores that default behavior, outputting the raw value of the field. The main frame output is too early in the view process and needs to be fully rendered first, so it can be themed as views, so the views can be themed.

An easy way to see this in action would be to create a normal view (not slideshow) and output the node ids as fields. Your output will be "1,2,3,etc". Now, create a views-view-fields--viewname.tpl.php with the following code:

<?php foreach ($fields as $id => $field): ?>
  <?php if (!empty($field->separator)): ?>
    <?php print $field->separator; ?>
  <?php endif; ?>

  <<?php print $field->inline_html;?> class="views-field-<?php print $field->class; ?>">
    <?php if ($field->label): ?>
      <label class="views-label-<?php print $field->class; ?>">
        <?php print $field->label; ?>:
      </label>
    <?php endif; ?>
      <?php 
      // !custom start
	    if ($field->class == 'nid') {	  
		  $field->content = 'abc';
		  drupal_set_message($field->content);		  
		}
      // custom end
	  ?>
      <<?php print $field->element_type; ?> class="field-content"><?php print $field->content; ?></<?php print $field->element_type; ?>>
  </<?php print $field->inline_html;?>>
<?php endforeach; ?>

The output of this view will be "abc,abc,abc,etc" and drupal message will also say "abc,abc,abc,etc";

However, if we change the view to be a slideshow type, and the nid field to be in the main frame, the output will be "1,2,3" while the drupal message says "abc". The normal views override is ignored.

That's my reasoning for it being a views slideshow issue rather than a views issue.

I'm not at DrupalCon, but I live in Berkeley, which is very close. If you don't have any plans tonight, there's an amazing pianist/vocalist friend of mine who will be playing at Cafe Gratitude in Berkeley 7-10pm. I'm planning on being there. I'll attach the flyer.

I'll check out the theme function and report back.

Well... I got it to work using the following:

function phptemplate_views_slideshow_thumbnailhover_no_display_section($view, $rows, $id, $options, $teaser = TRUE) {
  // Add the slideshow elements.
  $attributes['id'] = "views_slideshow_thumbnailhover_teaser_section_$id";
  $attributes['class'] = 'views_slideshow_thumbnailhover_teaser_section views_slideshow_teaser_section';
  $attributes = drupal_attributes($attributes);

  $output = "<div$attributes>";
  foreach ($view->result as $count => $node) {
    if ($view->display_handler->uses_fields()) {
      $rendered = '';
      foreach ($options['views_slideshow_thumbnailhover']['main_fields'] as $field => $use) {
        if (is_object($view->field[$field])) {
          $rendered_field = $view->field[$field]->theme($node);
		  
          // If the field is excluded then don't display it.
          // It must be rendered first though so that Custom Text can use it.
          if (!$view->field[$field]->options['exclude']) {
            if (($use !== 0) && !empty($rendered_field)) {
              $rendered .= '<div class="views-field-'. views_css_safe($view->field[$field]->field) .'">';
              if ($view->field[$field]->label()) {
                $rendered .= '<label class="view-label-'. views_css_safe($view->field[$field]->field) . '">';
                $rendered .= $view->field[$field]->label() . ':';
                $rendered .= '</label>';
              }
              $rendered .= '<div class="views-content-'. views_css_safe($view->field[$field]->field) .'">';
              // !custom $rendered .=  $rendered_field;
              if ($use == 'nid' && is_numeric($rendered_field)) {
				$rendered .= node_view(node_load($rendered_field),true);
			  } else {
				$rendered .= $rendered_field;
			  }
              // end custom
              $rendered .= '</div>';
              $rendered .= '</div>';
            }
          }
        }
      }
    }
    else {
      $rendered = node_view(node_load($node->nid), $teaser, FALSE, FALSE);
    }
    $output .= theme('views_slideshow_thumbnailhover_no_display_teaser', $rendered, $id, $count);
  }
  $output .= "</div>";
  return $output;
}

But it does seem a bit roundabout just to get the tpl-overridden teaser to display correctly.

Just to summarize what I did for reference:
* Create a view (Views Slideshow)
* Add set it to Thumbnail Hover
* Add two fields - Node:Nid and whatever other you want to use for breakouts
* Slideshow settings: set Node:Nid as the main frame and the other field as breakouts
* Override your node teaser display using node.tpl.php
* Use the above function to convert Node:Nid field into an overridden teaser display

Now the teaser shows up as it's overridden by node.tpl.php

Best,
Andrey.

It works as long as I rebuild the theme registry on every request, but as soon as that's turned off, I get nothing in the main frame.

Any ideas?

Andrey.

Nope, it doesn't get themed, that's actually the main problem. If it got themed, I wouldn't have to do any roundabout scripts.

A.

Just tried renaming to themename_ instead of phptemplate_, no luck. First refresh after rebuilding theme registry it works, but every following reload the main frame is empty.

A.

Is that very different from what I did before?

I just tried what you suggested though, and had overridden the teaser field with views-view-field--viewname--teaser.tpl.php. And it seems to have the same problem - when the registry is not rebuilt on every page, the teaser is empty.

Even if I use as simple override as "echo '123';" the main frame still comes blank.

The interesting thing is that if I put in dpm($row) into the tpl override, all the data is still there. It's only the display that's not working.

Any ideas on how to further troubleshoot this?
Andrey.

I think this may have to do with #591804: Theme registry build bug: External file with template_preprocess is not loaded if tpl.php is copied into theme.

I'll upgrade Drupal and report back.

Thanks,
Andrey.

Yep, that was it. All works now as expected after upgrading Drupal to 6.16.

I ended up using views-view-field--viewname--nid.tpl.php with the following to get the normal tpl-themed teaser:

$node = node_load($row->nid);
print node_view($node,true);
