Actions in Views Bulk Operations

Views Bulk Operations come handy when doing bulk operations over a selected list. This is great because it combines the power of views to filter the selection and specific actions to do on each selected entity. For Ex: Updating some field in the record, deleting selected entity and so on.

Views also provide an easier way to define your own set of custom functions to perform on each selected row of entities.

First, we need to define an action :

Search for drupal_set_time_limit in Drupal directory and modify the line as below. Ensure that it is restored later once the required operation is over:

<?php
drupal_set_time_limit
(240);
?>

and set to 1800.

Creating exportable field definitions in Drupal 7

There are times when we would want to create similar data structures across multiple drupal sites for common functionalities. Although this can be done using features but when the effort involves one time exercise and involves just few fields to be exported, using custom code for creating export definitions for importing in the other site can be a simpler alternative.

If you want export a field definition, you can use the handy field_info_field and field_info_instance functions. Taking our example above, here's how you would call these two functions:
