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

Submitted by Benjamin Melançon on March 12, 2008 - 3:10pm

Searched words:

theme div class field-item avoid skip solution views do not group multiple values

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.

themed link view, ugh ugh ugh ugh it's wrapping the plain text link in divs-- OH THE IDIOCY

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
content_views_field_handler_group
content_views_field_handler_group
views_handler_field_nodelink
content_views_field_handler_group

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.
