How To Make an Auto-Generated Storage Code After User Registration

  • Function to generate 5-digit storage code
    Copy and paste this code:

    
function jdl_generate_storage_code(){

  global $wpdb;

  $prefix = apply_filters( 'wpcsc_storage_code_prefix', 'BOX' );

  $randomize  = rand(11111,99999);

  $storage_code = $prefix.$randomize;

  $sql        = "SELECT COUNT(*) FROM $wpdb->usermeta WHERE `meta_key` LIKE '_jdl_storage_code' AND `meta_value` LIKE %s";

  $is_exist   = $wpdb->get_var( $wpdb->prepare( $sql, $storage_code ) );

  if( !$is_exist ){

    return $storage_code;

  }

  return jdl_generate_storage_code();

}
  • Generate and save storage code when a user registers:
    Copy and paste this code:

    
function jdl_generate_save_storage_code( $user_id, $user_data ){

  $unique_code = jdl_generate_storage_code();

  update_user_meta( $user_id, 'consolidation_code', $unique_code );

add_action( 'wpcfe_after_user_registration_success', 'jdl_generate_save_storage_code', 10, 2 );
  • Generate and save storage code for existing users on update:
    Copy and paste this code:

    function jdl_generate_save_storage_code_for_existing_users( $user_data ){

  $_user_id = (int)$user_data->ID;

  if( !get_user_meta( $_user_id, 'consolidation_code', true ) ){

    update_user_meta( $_user_id, 'consolidation_code', jdl_generate_storage_code() );

  }

}

add_action( 'wpcumanage_after_save_user', 'jdl_generate_save_storage_code_for_existing_users', 10, 1 );
  • Show storage code on user’s list: ( requires WPCargo User Management Addon )
    Copy and paste this code:

    

function wpcumanage_user_table_header_storage_code(){

  echo "".__('Storage Code', 'wpcargo-customizer')."";

}

add_action( 'wpcumanage_user_table_header', 'wpcumanage_user_table_header_storage_code' );

function wpcumanage_user_table_data_storage_code( $user ){

  echo ''.get_user_meta( (int)$user->ID, 'consolidation_code', true ).'';

}

add_action( 'wpcumanage_user_table_data', 'wpcumanage_user_table_data_storage_code' );
