What is WordPress Hook: found_networks_query
The found_networks_query hook is a specific hook in WordPress that allows developers to modify the SQL query used to retrieve the list of networks in a multisite installation.
Understanding the Hook: found_networks_query
The found_networks_query hook is located within the WP_Network_Query class, which is responsible for querying and retrieving network data from the database. This hook is triggered just before the SQL query is executed, allowing developers to modify the query parameters or add additional conditions.
Hook Parameters (if applicable): found_networks_query
The found_networks_query hook accepts a single parameter, $query, which is an instance of the WP_Query object representing the network query. Developers can modify this object to change the query parameters, such as adding custom meta queries or modifying the orderby and order parameters.
Hook Doesn’t Work: found_networks_query
If the found_networks_query hook doesn’t seem to be working as expected, it could be due to incorrect usage or conflicts with other plugins or themes. Developers should ensure that they are using the hook within the appropriate context and that their modifications to the query are valid SQL syntax.
Best Practices & Usage Notes (if applicable): found_networks_query
When using the found_networks_query hook, developers should be mindful of the potential impact on performance, as modifying complex SQL queries can have unintended consequences. It’s also important to document any modifications made to the query for future reference and to avoid conflicts with other code.
found_networks_query Usage Example: found_networks_query
“`php
function custom_network_query( $query ) {
$query->set( ‘meta_key’, ‘custom_field’ );
$query->set( ‘meta_value’, ‘desired_value’ );
}
add_action( ‘found_networks_query’, ‘custom_network_query’ );
“`
In this example, the found_networks_query hook is used to add a custom meta query to the network query, filtering the results based on a specific meta key and value.
