What is WordPress Hook: pre_get_networks
The pre_get_networks hook in WordPress is used to modify the network query before it is executed. This allows developers to customize the network query parameters and results.
Understanding the Hook: pre_get_networks
The pre_get_networks hook is located within the WordPress query process, specifically before the network query is executed. It provides a way for developers to alter the parameters of the network query and customize the results based on specific criteria.

The pre_get_networks hook accepts parameters such as the network query object, which can be used to modify the query parameters and customize the results. Developers can also use conditional statements within the hook to further refine the network query based on specific conditions.
Hook Doesn’t Work: pre_get_networks
If the pre_get_networks hook doesn’t work as expected, it may be due to incorrect implementation or conflicts with other hooks or functions. It is important to ensure that the hook is added at the appropriate stage of the WordPress query process and that any modifications to the network query are properly applied.
Best Practices & Usage Notes (if applicable): pre_get_networks
When using the pre_get_networks hook, it is important to consider the potential impact on performance, as modifying the network query can affect the overall execution time. It is recommended to use the hook sparingly and to thoroughly test any modifications to ensure they produce the desired results without negatively impacting the site’s performance.
Usage Example: pre_get_networks
“`php
function custom_network_query( $query ) {
if ( $query->is_main_query() && $query->is_network() ) {
$query->set( ‘orderby’, ‘name’ );
$query->set( ‘order’, ‘ASC’ );
}
}
add_action( ‘pre_get_networks’, ‘custom_network_query’ );

In this example, the pre_get_networks hook is used to modify the network query parameters to order the results by name in ascending order. This demonstrates a basic use case of the pre_get_networks hook within WordPress functions.
