Massive Actions

Massive action controls


Add to itemtypes search lists:

  • a checkbox before each item,
  • a checkbox to select all items checkboxes,
  • an Actions button to apply modifications to each selected items.

Update item’s fields

The first option of the Actions button is Update. It permits to modify the fields content of the selected items.

The list of fields displayed in the sub list depends on the Search options of the current itemtype. By default, all Search options are automatically displayed in this list. To forbid this display for one field, you must define the key massiveaction to false in the Search options declaration, example:


$tab[] = [
   'id'            => '1',
   'table'         => self::getTable(),
   'field'         => 'name',
   'name'          => __('Name'),
   'datatype'      => 'itemlink',
   'massiveaction' => false // <- NO MASSIVE ACTION

Specific massive actions

After the Update entry, we can declare additional specific massive actions for our current itemtype.

First, we need declare in our class a getSpecificMassiveActions method containing our massive action definitions:



function getSpecificMassiveActions($checkitem=NULL) {
   $actions = parent::getSpecificMassiveActions($checkitem);

   // add a single massive action
   $class        = __CLASS__;
   $action_key   = "myaction_key";
   $action_label = "My new massive action";
   $actions[$class.MassiveAction::CLASS_ACTION_SEPARATOR.$action_key] = $action_label;

   return $actions;

A single declaration is defined by these parts:

  • a classname
  • a separator: always MassiveAction::CLASS_ACTION_SEPARATOR
  • a key
  • and a label

We can have multiple actions for the same class, and we may target different class from our current object.

Next, to display the form of our definitions, we need to declare a showMassiveActionsSubForm method:



static function showMassiveActionsSubForm(MassiveAction $ma) {
   switch ($ma->getAction()) {
      case 'myaction_key':
         echo __("fill the input");
         echo Html::input('myinput');
         echo Html::submit(__('Do it'), array('name' => 'massiveaction'))."</span>";


   return parent::showMassiveActionsSubForm($ma);

Finally, to process our definition, we need a processMassiveActionsForOneItemtype method:



static function processMassiveActionsForOneItemtype(MassiveAction $ma, CommonDBTM $item,
                                                    array $ids) {
   switch ($ma->getAction()) {
      case 'myaction_key':
         $input = $ma->getInput();

         foreach ($ids as $id) {

            if ($item->getFromDB($id)
                && $item->doIt($input)) {
               $ma->itemDone($item->getType(), $id, MassiveAction::ACTION_OK);
            } else {
               $ma->itemDone($item->getType(), $id, MassiveAction::ACTION_KO);
               $ma->addMessage(__("Something went wrong"));

   parent::processMassiveActionsForOneItemtype($ma, $item, $ids);

Besides an instance of MassiveAction class $ma, we have also an instance of the current itemtype $item and the list of selected id ``$ids.

In this method, we could use some optional utility functions from the MassiveAction $ma object supplied in parameter :

  • itemDone, indicates the result of the current $id, see constants of MassiveAction class. If we miss this call, the current $id will still be considered as OK.
  • addMessage, a string to send to the user for explaining the result when processing the current $id
