What is WordPress Hook: network_allowed_themes
The network_allowed_themes hook is a WordPress filter that allows network administrators to control which themes are available for activation on a multisite network.
Understanding the Hook: network_allowed_themes
The network_allowed_themes hook is located within the WordPress multisite network administration process. It allows network administrators to define an array of themes that are allowed to be activated on the network.
Hook Parameters (if applicable): network_allowed_themes
The network_allowed_themes hook accepts an array parameter that contains the list of themes allowed for activation on the multisite network. Each theme is represented by its directory name within the wp-content/themes directory.
Hook Doesn’t Work: network_allowed_themes
If the network_allowed_themes hook doesn’t seem to be working, it could be due to incorrect usage of the hook or conflicts with other theme management plugins. It’s important to ensure that the array of allowed themes is properly formatted and that there are no conflicting filters or functions affecting the hook.
Best Practices & Usage Notes (if applicable): network_allowed_themes
When using the network_allowed_themes hook, it’s important to consider the potential impact on network security and performance. Limiting the number of allowed themes can help maintain a consistent user experience and reduce the risk of security vulnerabilities. However, it’s also important to provide enough flexibility for site administrators to choose suitable themes for their individual sites within the network.
Usage Example: network_allowed_themes
“`php
function custom_network_allowed_themes( $allowed_themes ) {
// Define an array of allowed themes
$allowed_themes = array( ‘twentytwenty’, ‘twentynineteen’, ‘my-custom-theme’ );
return $allowed_themes;
}
add_filter( ‘network_allowed_themes’, ‘custom_network_allowed_themes’ );
“`
