function weight_form_alter in Weight 6

Same name and namespace in other branches

1. 5 weight.module \weight_form_alter()
2. 7 weight.module \weight_form_alter()

Implementation of hook_form_alter().

This is where we tweak the admin/content/node to include our weight selector; hide the 'sticky' filter (it won't work when using weight module), and add some help text to the form.

File

./weight.module, line 165

This module uses the sticky column of the node table to add weighting to nodes.

Code

function weight_form_alter(&$form, $form_state, $form_id) {
  $weight_node_types = variable_get('weight_node_types', array_flip(node_get_types('names')));

  // Node edit page weight selector.
  if (isset($form['type']) && $form['type']['#value'] . '_node_form' == $form_id) {
    $node = $form['#node'];
    if (user_access('assign node weight') || user_access('administer nodes')) {
      if (in_array($node->type, $weight_node_types)) {
        $range = variable_get('weight_range', 20);
        $position = variable_get('weight_position', 0);
        $default = variable_get('weight_default', 0);
        $where = 'weight_form';
        if ($position == 10 && user_access('administer nodes')) {

          // We will add it to the Workflow fieldset.
          $where = 'options';
          $form['options']['#collapsed'] = isset($node->node_weight) ? $node->node_weight == 0 : FALSE;
        }
        else {

          // Add the node weight selector fieldset.
          $form['weight_form'] = array(
            '#type' => 'fieldset',
