I am trying to get the user ID during registration and automatically add that ID to my custom table. I am using the WP-Members plugin for registration.

Is it possible to get user ID on the fly while registering and add that ID to another custom table with WP-Members plugin.

Or I could use a custom registration page if required; but I need some guidance how to get user ID on the fly during registration.

Anyone please help me...


Please take a look at user_register hook

This is fired when a new user is registered and conveniently passes you the user ID of the new user.

function function_name( $user_id )
    /* do what you want to do with ID here */
add_action( 'user_register', 'function_name');
  • Thanks a lot for quick response. Actually I have never done this before so little confuse and need great help from you experts. So in between this I can use $wpdb inser command for inserting user ID to custom table? and how can I know that I should use $user_id and $user_name etc? sorry for dumb question – pixelngrain Aug 30 '12 at 11:11
  • codex.wordpress.org/Function_Reference/get_userdata will get you all the user details from the ID – Brady Aug 30 '12 at 11:20
  • My table name is wp_customs and column is customs_id and I tired below code but didn't insert user id when they registers. function get_customs_id($user_id){ global $wpdb; $wpdb->insert( 'wp_customs', array( 'customs_id' => 'value1' ), array( '%d' ) ); } add_filter('user_register', 'get_customs_id'); – pixelngrain Aug 30 '12 at 11:27
  • Where did you put this code? – Brady Aug 30 '12 at 11:30
  • In theme function.php ..I want to get user id and need to inset into that table when user get register – pixelngrain Aug 30 '12 at 12:23

@Brady's answer is correct because WP-Members does use WP's function for inserting a new user, so that action does get called. And if you want flexibility and you are only using the new user's ID for all of it, that's a good approach.

But a secondary approach would be to use WP-Members' wpmem_post_register_data action. That action passes all of the user's registration data an array keyed by the field meta keys and it includes ID.

add_action( 'wpmem_post_register_data', 'my_reg_hook' );
function my_reg_hook( $fields ) {
     * ID is available as $fields['ID']
     * Other fields are $fields['the_fields_meta_key']
     * do your stuff here

The documentation for the action has a list of fields that will be included in the array in addition to any custom fields that are in there by meta key:
