attach_session_information filter
Can be used to attach further information to a session.
To use the attach_session_information filter, first, you have to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin.
We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.
In the below live examples, we have defined a function modify_attach_session_information_defaults which takes 2 parameters and we registered it using add_filter. The first parameter attach_session_information is the name of the hook, the second parameter modify_attach_session_information_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.
Sometimes, you have to remove a registered hook so you can use remove_filter to remove the attach_session_information filter.
Parameters
Live Example
apply_filters('attach_session_information', array $session, int $user_id)Below are examples of how you can use this hook.
Example 1: Modifying Session Information
In this example, we modify the session information based on custom requirements.
function weplugins_modify_attach_session_information_defaults($session, $user_id) {
// Update the $session variable according to your website requirements and return this variable.
$session['custom_data'] = 'Custom Value';
return $session;
}
// add the filter
add_filter("attach_session_information", "weplugins_modify_attach_session_information_defaults", 10, 2);
Example 2: Adding User Meta to Session
This example demonstrates how to add user meta information to the session data.
function weplugins_add_user_meta_to_session($session, $user_id) {
$user_meta = get_user_meta($user_id, 'custom_meta_key', true);
$session['user_meta'] = $user_meta;
return $session;
}
// add the filter
add_filter("attach_session_information", "weplugins_add_user_meta_to_session", 10, 2);
Example 3: Removing a Hook Callback
To remove a previously added hook callback, use the example below.
remove_filter("attach_session_information", "weplugins_modify_attach_session_information_defaults", 10, 2);
Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
