Views in Drupal provides several hooks that allow you to customize and extend the behavior and output of views. These hooks can be used to modify the query, add custom fields, filters, and more. Some of the important hooks related to Views in Drupal include:
hook_views_api(): This hook is used to declare the version of the Views module you are implementing. It is typically used in custom modules that provide additional functionality to Views.
hook_views_data(): This hook allows you to define the data your module will make available to Views. It's especially useful when creating custom tables and data sources for Views.
hook_views_query_alter($view, $query): This hook allows you to alter the View's database query. You can modify or extend the query conditions, joins, and more.
hook_views_pre_execute($view): Use this hook to perform actions just before the View is executed, but after the query has been built. You can manipulate the result set or make other changes.
hook_views_post_execute($view): This hook lets you process the View's result set after the query is executed but before rendering the output. You can alter, sort, or process the results.
hook_views_pre_render($view): This hook allows you to perform actions before the View's output is rendered. It's useful for altering the output array or making last-minute adjustments.
hook_views_post_render($view, $output): Use this hook to process the rendered output of the View. You can make additional modifications to the HTML markup before it's sent to the browser.
hook_views_handlers(): This hook lets you define custom handlers for fields, filters, and sort criteria in Views. You can create custom field handlers, for example, to display data in a specific way.
hook_views_plugins(): This hook is used to declare custom plugins for Views. It's particularly handy if you're creating your own field, filter, or sort handler plugin.
hook_views_query_substitutions(): You can use this hook to define SQL query substitutions that can be applied to the Views query, for instance, to replace placeholders with dynamic values.
- hook_views_data_alter(&$data): This hook allows you to alter the data definitions provided by other modules for use in Views. You can add, modify, or remove fields and tables from the Views data.
These hooks offer a great deal of flexibility and customization when working with Views in Drupal. Depending on your project's requirements, you can implement one or more of these hooks to tailor your Views to your specific needs.
