Wordpress - Is there a hook that runs after a user logs in?
The action hook wp_login runs when the user logs in - it can run a simple function.
function do_anything() {
//do stuff
}
add_action('wp_login', 'do_anything');
documentation : https://codex.wordpress.org/Plugin_API/Action_Reference/wp_login
The real breadwinner here is wp_authenticate
which has a bit of documentation. It passes an array with the given username and password, which gives you the opportunity to pass info to the remote service, if necessary.
https://codex.wordpress.org/Plugin_API/Action_Reference/wp_authenticate
and to change the redirect URL after login, there is the filter login_redirect
: https://codex.wordpress.org/Plugin_API/Filter_Reference/login_redirect
I would caution against using wp_login
. It is deprecated and in later versions of WordPress it may not work at all. Instead try the wp_signon
function.
Edit: The wp_login
function is deprecated but the wp_login
action is still fine to use.
