 A silly trip through the innards of views theming: output plain link with no HTML

A silly trip through the innards of views theming: output plain link with no HTML

Spoiler: if you want a plain value of a field to be output plain without surrounding <div class="field-item"> tags, make sure to select "Do not group multiple values".

Now for the masochists, let's follow how I found this out the really, really, really hard way!

Amazing what's available to a simple view in Drupal 5.

A views-list-agaric_view_name.tpl.php with the following sole contents:

<?php
print '<pre>';
print_r(get_defined_vars());
print '</pre>';
?>

Outputs the below. Remember that what you print is already all wrapped in <li> tags.

The easy access to available fields is at the bottom.

    An issue filed:

    http://drupal.org/node/233304

    Related, might as well patch all at once:

    http://drupal.org/node/141571
    http://drupal.org/node/209685

    It's not Link's fault:

    quicksketch - March 12, 2008 - 12:38

    CCK is the one adding that wrapped DIV around the result. I think it's put in there when the default code output by views theming wizard calls views_theme_field('views_handle_field', $field['queryname'], $fields, $field, $node, $view);. Prior to that the field is properly just the URL. I don't think there's anything at the link.module level that can be done.

    <?php
      if ($formatter == 'plain') {
    drupal_set_message($item['url']);
    drupal_set_message('<pre>'.print_r($item,TRUE).'</pre>');
        return check_plain($item['url']);
      }
    ?>

    Pure and innocent:

                   <div class="messages status">
    <ul>

      <li>http://www.plwc.org/PLWC/Library/Podcasts/2007_Breast_Cancer_Symposium.mp3</li>
      <li><pre>Array
    (
        [url] => http://www.plwc.org/PLWC/Library/Podcasts/2007_Breast_Cancer_Symposium.mp3
        [title] =>
        [attributes] => N;
    )

    My apologies to Link, this makes it easy to fix on theme layer...

    some drupal_set_message output to see what's happening:

    <?php
    function views_theme_field() {
      $args = func_get_args();
      $function = array_shift($args);
      $field_name = array_shift($args);
      $view = array_pop($args);
    drupal_set_message('function: '. $function);
    drupal_set_message('<br />field name: '. $field_name);
    drupal_set_message('<pre>'.print_r($view,TRUE).'</pre>');

      if (!($func = theme_get_function($function . '_' . $view->name . '_' . $field_name))) {
        if (!($func = theme_get_function($function . '_' . $field_name))) {
          $func = theme_get_function($function);
        }
      }

      if ($func) {
        return call_user_func_array($func, $args);
      }
    }
    ?>

    So way up there you can see it provided two functions to try in the views handler-- the first was very general (views_handle_field) and the second very specific (node_data_field_resource_link_field_resource_link_url)

    Following the general first:

    function theme_views_handle_field($fields, $field, $data) {

    }

    <?php
    /**
     * Themeable function to handle displaying a specific field.
     */
    function theme_views_handle_field($fields, $field, $data) {
      $info = $fields[$field['fullname']];
    drupal_set_message($field['handler']);
    ?>

    ...

    Output for a bunch of views:

    views_handler_field_nodelink

    views_handler_field_nodelink

    Culprit:

    <?php
    function theme_content_view_multiple_field($items, $field, $data) {
      foreach ($items as $item) {
        $output .= '<div class="field-item">'. $item .'</div>';
      }
      return $output;
    }
    ?>

    And, behold, simply selecting "Do not group multiple values" for that field display in the edit view form solved all problems in the world.

    Note:

    <?php
    function phptemplate_node_data_field_resource_link_field_resource_link_url($fields, $field, $data) {
      return check_plain($data->$field['queryname']);
      drupal_set_message('<pre>'.print_r($data,TRUE).'</pre>');
    }
    ?>

    Did not get called, and I expected that it would. So I learned very little in this particular trip through the views theming rabbit hole.
