Hi I am trying to capture which user updates a form and input that current users last name into a hidden field. on the form. I think integrating a WP function to retrieve the current user into a hook might work, but I am not experienced in this and am not sure how to proceed. I put a hook I've used before but put pre determined values in the "New Value" ideally i would put the current "user_username" for the new value but not sure how to do that.   Word Press Functions   wp_get_current_user(): WP_User     <?php
$current_user = wp_get_current_user(); /*
* @example Safe usage: $current_user = wp_get_current_user();
* if ( ! ( $current_user instanceof WP_User ) ) {
* return;
* }
*/
printf( __( 'Username: %s', 'textdomain' ), esc_html( $current_user->user_login ) ) . '<br />';
printf( __( 'User email: %s', 'textdomain' ), esc_html( $current_user->user_email ) ) . '<br />';
printf( __( 'User first name: %s', 'textdomain' ), esc_html( $current_user->user_firstname ) ) . '<br />';
printf( __( 'User last name: %s', 'textdomain' ), esc_html( $current_user->user_lastname ) ) . '<br />';
printf( __( 'User display name: %s', 'textdomain' ), esc_html( $current_user->display_name ) ) . '<br />';
printf( __( 'User ID: %s', 'textdomain' ), esc_html( $current_user->ID ) );   The Hook I was thinking about using   add_filter('frm_setup_edit_fields_vars', 'frm_set_edit_val', 20, 3);
function frm_set_edit_val( $values, $field, $entry_id ) {
if ( $field->id == 171 ) { //Replace 171 with your field ID
// If on the back-end, don't adjust field value
if ( FrmAppHelper::is_admin() ) {
return $values;
} // If on front-end set a specific field value
$values['value'] = 'new value';
}
return $values;
}
