Implementation of hook_taxonomy. Capture term updates - including submission of the term edit form

File

contributed/taxonomy_image_attach/taxonomy_image_attach.module, line 139

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_taxonomy($op, $type, $form_values = NULL) {
  $directory = file_create_path(variable_get('taxonomy_image_path', 'category_pictures'));
  file_check_directory($directory, FILE_CREATE_DIRECTORY);

  // We're only interested in term changes.
  if ($type != 'term') {
    return;
  }

  switch ($op) {
    case 'insert':
    case 'update':
      if (file_check_upload('path')) {

        // An upload will have just happened. Not our problem, don't even try to interfere.
        break;
      }
      if ($form_values['current_image_delete'] == 1) {

        // Then don't immediately re-attach it!
        break;
      }
      $is_current_image = db_result(db_query('SELECT COUNT(tid) FROM {term_image} WHERE tid=%d', $tid));
      if ($iid = $form_values['iid']) {
        $oldpath = db_result(db_query('SELECT path FROM {term_image} WHERE tid=%d', $tid));
        if ($is_current_image) {

          // Delete old image before saving the new one,
          // Image files outside of the dedicated directory should be safe
          taxonomy_image_delete($tid);
        }
        $image_node = node_load($iid);

        // choose size
