Custom Code in PHPtemplate

The following functions were added to PHPtemplate in the lasqueti theme to obtain the required functionality. Some of these should probably be made into a custom module.

Custom Node (page) titles using images

see: HowTo: Replace node title with a related image | drupal.org

<code>

// This function is used to substitue the node title with an image of the same name.
// Really good candidate to turn into a small module.
function _phptemplate_variables($hook, $vars = array()) {
switch ($hook) {
    case 'page':
    // substitute node title with an image, if a suitable replacement can be found.
    // save original title text for use in head and breadcrumb.
    $vars['breadcrumb_title'] = $vars['title'];
    $vars['head_title'] = $vars['title'];
    // Substitute title only for nodes...
    if (arg(0) == 'node' && is_numeric(arg(1))) {
      $node = node_load(arg(1)); // (expensive, unless arg(1) is already loaded, which is should be at this point.)
      // ... of one of the listed types - add node types to process to the array.
      if (in_array($node->type, array('page', 'page_layout_b'))) {
        // convert title to suitable filename and derive both file system path and URL.
        $titleFile = clean_title($vars['title']) . '.gif';
        $titleImage = base_path() . "files/images/titles/" . $titleFile;
        $titleURL = "http://" . $_SERVER['SERVER_NAME'] . $titleImage;
        $titlePath = $_SERVER['DOCUMENT_ROOT'] . $titleImage;
        // $vars['title'] = $titleURL;   // DEBUG - see what's being produced

        // Determine if a suitable replacement image for title can be found, and make substitution.
        if ( file_exists($titlePath) ) {
          $newTitle = '<img alt=\'' . $vars['title'] .'\' src=\'' . $titleURL .'\' />';
          $vars['title'] = $newTitle;
        }
      }
    }
    break;
}

return $vars;
}

// Prepare some general title text for use as a file name.
// Remove special HTML characters, trim whitespace, convert to lower-case
// repace spaces with underscores.
function clean_title($string)
{
    $cleanString = htmlspecialchars_decode( strtolower(trim($string)), ENT_QUOTES );
    $cleanString = str_replace(array("& ", "'"), '', $cleanString);
    // $string = strtolower(preg_replace("/[^a-zA-Z0-9 ]/", "", $string)); // slower, but more general purpose.
    return str_replace(' ', '_', $cleanString );;

Custom Theming for Summary Views

Theme the node add / edit forms for custom CCK types

This simply addes a collapsible fieldset for the CCK fields in the "Market Page" type, and hides the Categories fieldset from non-admins, to try to improve useability. See http://drupal.org/node/101092#comment-748013 for details.

function phptemplate_page_layout_b_node_form($form) {
// Collapse the taxonomoy fieldset by default (as this rarely changes).
$form['taxonomy']['#collapsed'] = true;

// enforce crude access rights on the taxonomy terms.
global $user;
if (!($user->uid==1 || in_array('contributor',$user->roles)) ) {
    unset($form['taxonomy']);
}
// These are the fields that should be in the fieldset
$fields = array('field_teaser_image', 'field_bio_image', 'field_bio');

// Add fieldsets to the page_layout_b input form & render it.
    _add_fieldset($form, 'Images', $fields);
    return drupal_render($form);
}

/**
* Add the given fields to a new fieldset on the form.
* @form - the form to add the fieldset to
* @name - a string name of the fieldset
* @fieldsInSet - field ids (names) for the fields in
* the form that should go into the fieldset.
*/

Custom theme the book navigation links.

When a node's page is viewed in a tab, we don't want to show any book navigation.

function phptemplate_book_navigation($node) {
if ($node->inTab)
return NULL;
else
return theme_book_navigation($node);
}

Custom display of Views exposed filter

Exposed filters allow the user to have control over what nodes are viewed by selecting from a widget. The default layout is to have the widget displayed above the view, in the page - yuck - very ugly and poor usability. This "snippet" hides the default exposed filter for a view with the name "test" - it can be copied for any View where you want to do this. Then a custom block is created to display the exposed filter widget off to the side, or "rolled-up"! Much nicer.
See http://www.angrydonuts.com/displaying_views_exposed_filters

function phptemplate_views_display_filters_test() {
// Do absolutely nothing.
}
