I am using this function to get the information of User.But unfortunately i can't able to access the user meta data.Forexample first_name,last_name etc

{        
$firstname=get_user_meta($user_ID,'first_name',true);

I am receiving newly register user's id from $user_ID but cannot able to get the value in $firstname.How can i get the user meta record after registering new user? Thanks for any Help!

Answer 1

From codex results example :

Array ( [first_name] => Array ( [0] => Tom ) [last_name] => Array ( [0] => Auger) [nickname] => Array ( [0] => tomauger ) [description] => etc.... )

That means, first_name is an array and you should access first element in array first_name to get it:

function registerUserInSalesForce($user_ID)
{        
$firstname=get_user_meta($user_ID,'first_name',true);
update_option('update_meta',$firstname[0]);
}
add_action( 'user_register', 'registerUserInSalesForce');

I'm not sure if this will be able to help, as it depends on which data do you need. But firstName and lastName are definitely available.

You need to use the $userdata parameter, and for that you need to provide and add some parameters to your functions:

function registerUserInSalesForce( $user_id, $userdata )
{        
    $firstname = $userdata['first_name'];
    //$firstname = $userdata['last_name'];
    update_option('update_meta', $firstname);
}
add_action( 'user_register', 'registerUserInSalesForce', 10, 2);

This information is part of the user's information, and it's not user meta. User meta doesn't exist yet when this hook triggers.
