Add an image selector to the taxonomy_image fieldset alongside the upload field.

File

contributed/taxonomy_image_attach/taxonomy_image_attach.module, line 73

Add functionality to terms similar to the image_attach.module. Allow a term editor to choose from EXISTING images rather than upload new ones all the time. Currently this uses image.module handling of image nodes to index available images.

Code

function taxonomy_image_attach_form_alter($form_id, &$form) {
  switch ($form_id) {
    case 'taxonomy_form_term':
      $current_image = taxonomy_image_get_object($form['tid']['#value']);
      $current_filepath = $current_image->path;

      // Reverse-lookup to figure what this attached image is, if any.
      $file = db_fetch_object(db_query("SELECT * FROM {files} WHERE filepath = '%s'", $current_filepath));

      // If none, no problem.
      $all_images = taxonomy_image_attach_get_image_nodes();
      $form['taxonomy_image']['image_attach']['iid'] = array(

      $size_options = array();
      foreach ($sizes as $size => $size_def) {
        $size_options[$size] = $size;
