I am using VBO to perform bulk operations on my view. I have 2 core VBO actions and 2 custom actions.

  • Publish comment
  • Unpublish comment
  • Publish resource
  • Unpublish resource

When the Apply action button is clicked with none of the grid row is selected, I get this error message.

Select one or more comments to perform the update on.

I would like to rewrite this error message as An attachment has to be selected to perform this action.

How can I achieve this? I am aware of hook_views_bulk_operations_finish(), but it doesn't overwrite a specific action.

You could try the following:

  1. Define your own ViewsField plugin that extends the CommentBulkForm (that is where that message comes from)
<?php

namespace Drupal\your_module\Plugin\views\field;

use Drupal\views\Plugin\views\field\BulkForm;

/**
 * Defines a custom comment operations bulk form element.
 *
 * @ViewsField("custom_comment_bulk_form")
 */
class CustomCommentBulkForm extends CommentBulkForm {

  /**
   * {@inheritdoc}
   */
  protected function emptySelectedMessage() {
    return $this->t('An attachment has to be selected to perform  this action.');
  }

}

  1. Expose your plugin to views:
function your_module_views_data() {

  $data['comment']['custom_comment_bulk_form'] = [
    'title' => t('Custom comment operations bulk form'),
    'help' => t('Add a form element that lets you run operations on multiple comments, with custom messages.'),
    'field' => [
      'id' => 'custom_comment_bulk_form',
    ],
  ];

  return $data;
}
  1. Finally, overwrite (or override) your (views.view.) Comments configuration so that your existing 'Comment: Comment operations bulk form' field is forced to use your ViewsField plugin. One way to overwrite would be via drush:
drush cset views.view.comment \
  display.default.display_options.fields.comment_bulk_form.field \
  custom_comment_bulk_form

That would eventually allow you to set your own custom message:

Good luck!

  • Got a question. I have created the ViewsField plugin inside my module at this path - mymodule\src]plugin\views\field\custom_comment_bulk_form.php. But this path is nowhere referenced, neither in hook_views_data() nor in the config file. So how will my custom plugin file be read?

  • also I get to see "Error: Class 'Drupal\views\Plugin\views\field\BulkForm\CommentBulkForm' not found in include()" error from the plugin. :(
