What is WordPress Hook: add_link

The add_link hook in WordPress is used to add a new link to the database. It is commonly used in plugins or themes to dynamically add links to a website without the need for manual input.

Understanding the Hook: add_link

The add_link hook is located within the wp_insert_link function in WordPress. This function is responsible for inserting a new link into the database. The add_link hook allows developers to modify or add additional functionality to this process.

Hook Parameters (if applicable): add_link

The add_link hook accepts parameters such as $link_id, $linkdata, and $category. These parameters allow developers to access and modify the link data before it is inserted into the database.

Hook Doesn’t Work: add_link

If the add_link hook doesn’t work as expected, it may be due to conflicts with other plugins or themes that are also modifying the link insertion process. It is recommended to deactivate other plugins and switch to a default theme to troubleshoot the issue.

Best Practices & Usage Notes (if applicable): add_link

When using the add_link hook, it is important to consider the potential impact on performance, especially when adding additional database queries or complex logic. It is best practice to keep the modifications within the hook as minimal and efficient as possible.

Usage Example: add_link

“`php
function custom_add_link_function( $link_id, $linkdata, $category ) {
// Add custom logic or modifications to the link data here
}
add_action( ‘add_link’, ‘custom_add_link_function’, 10, 3 );
“`
