What is WordPress Hook: contextual_help

The contextual_help hook in WordPress is used to add contextual help tabs to the admin screens. These tabs provide users with additional information and guidance related to the specific page they are viewing within the WordPress dashboard.

Understanding the Hook: contextual_help

The contextual_help hook is located within the WordPress admin screens and is typically used in combination with the add_help_tab() function to add contextual help tabs to specific admin pages. This allows developers to provide users with relevant information and instructions directly within the WordPress dashboard.

Hook Parameters (if applicable): contextual_help

The contextual_help hook accepts parameters that include the unique identifier for the help tab, the title of the tab, the content to be displayed within the tab, and the screen or page where the tab should be added. These parameters allow developers to customize the contextual help tabs to provide specific information for different admin pages.

Hook Doesn’t Work: contextual_help

If the contextual_help hook is not working as expected, it may be due to incorrect usage of the add_help_tab() function or conflicts with other plugins or themes that modify the admin screens. To troubleshoot this issue, developers should review their code for any errors and deactivate other plugins or switch to a default theme to identify any conflicts.

Best Practices & Usage Notes (if applicable): contextual_help

When using the contextual_help hook, it is important to provide clear and concise information within the help tabs to assist users in understanding the functionality of the admin pages. Developers should also consider the placement and relevance of the contextual help tabs to ensure they provide valuable guidance without overwhelming users with excessive information.

Usage Example: contextual_help

“`php
function custom_admin_help_tab() {
$screen = get_current_screen();
if ( $screen->id === ‘edit-post’ ) {
$screen->add_help_tab( array(

‘title’ => ‘Custom Help’,
‘content’ => ‘
