FAQ

Where are the options for this plugin?

This plugin does not have a settings page. Simply put, I don’t like bloating my plugins with a bunch of options.

Instead, I try to develop functionality using the 80/20 principle so that for 80% of use cases you all you need to do is activate the plugin and it “just works”.

For the other 20% of you who want things to behave differently there are hooks available in the plugin so you can customize default behaviors.

Can I still allow concurrent logins for certain users?

Yes, simply add this code to your theme’s functions.php file or as an MU plugin:

function my_pcl_whitelist_user_ids( $prevent, $user_id ) {

    $whitelist = array( 1, 2, 3 ); // Provide an array of whitelisted user IDs

    return in_array( $user_id, $whitelist ) ? false : $prevent;

}
add_filter( 'pcl_prevent_concurrent_logins', 'my_pcl_whitelist_user_ids', 10, 2 );

Or this code to bypass users with certain roles:

function my_pcl_whitelist_roles( $prevent, $user_id ) {

    $whitelist = array( 'administrator', 'editor' ); // Provide an array of whitelisted user roles

    $user = get_user_by( 'id', absint( $user_id ) );

    $roles = ! empty( $user->roles ) ? $user->roles : array();

    return array_intersect( $roles, $whitelist ) ? false : $prevent;

}
add_filter( 'pcl_prevent_concurrent_logins', 'my_pcl_whitelist_roles', 10, 2 );

THIS PLUGIN IS SIMPLE AND PERFECT THAT THE AUTHOR HAS NOT NEED TO UPDATE ANYTHING SINCE LAST 4 YEARS. I had to create an account just to give this plugin a 5-star rating and let people know that it works perfectly. I was looking for something to prevent users from concurently login and found this plugin. However, the age of this plugin and the number of active installation (1000+ at this time) made me skip it. The information that this plugin was updated 4 years ago further drove me away. I decided to install another plugin, which made me crazy because it kept log me out every couple minutes. Then I removed the mentioned plugin and gave this plugin a try, and it works as much as I expect.

GREAT!
