Behavior of wp-config.php Constants for Updates

What is the effect of adding define('WP_AUTO_UPDATE_CORE', false); in the wp-config.php file?

A Disables all automatic WordPress core updates, including minor and major releases.

B Enables automatic updates only for major WordPress core releases.

C Enables automatic updates for plugins but disables core updates.

Correct Syntax to Enable Automatic Plugin Updates

Which code snippet correctly enables automatic updates for all plugins in WordPress?

Wordpress

<?php
// Choose the correct snippet to enable automatic plugin updates

A add_filter('auto_update_plugins', '__return_true');

B add_action('auto_update_plugin', '__return_true');

C add_filter('auto_update_plugin', '__return_true');

D add_action('auto_update_plugins', '__return_true');

💡 Hint

Filters modify values; actions run code without changing values.

The auto_update_plugin filter controls automatic updates for individual plugins. Returning true enables updates.

Debugging Automatic Theme Update Failure

A site owner added add_filter('auto_update_theme', '__return_true'); to enable automatic theme updates, but themes are not updating automatically. What is the most likely cause?

A The function '__return_true' is undefined and causes an error.

B The filter name should be 'auto_update_themes' (plural), not 'auto_update_theme'.

C Automatic theme updates are disabled in wp-config.php by default and cannot be enabled by filters.

D The filter must be added inside a function hooked to 'init' action to work.

💡 Hint

Check the exact filter name spelling and plurality.

The correct filter to enable automatic theme updates is auto_update_themes (plural). Using the singular form does nothing.

Result of Combined Update Filters

Given the following code in a WordPress plugin, what will be the output of var_dump(wp_get_update_data()); regarding plugin updates?

A The plugin updates will be enabled because 'auto_update_plugins' returns true.

B A fatal error occurs because both filters conflict.

C The output will show no plugin updates available regardless of filters.

D The plugin updates will be disabled because 'auto_update_plugin' returns false.

💡 Hint

Consider which filter controls individual plugin update behavior.

The auto_update_plugin filter controls automatic updates for each plugin individually. Returning false disables updates even if auto_update_plugins returns true.
