    Hi!

    I´m using WP as a CMS for an event and i´m now trying to make a list of all users in which i add a button at the end of each row, where i can reset (and re-send) the user-password. If i can´t get around this, i would have to reset every user with entering his/here e-mail adress into the lostpassword-form on wp-login.php.

    I looked through the function in wp-login.php but i can´t get around this. Could someone push me a little further and explain me how i would trigger those functions? Here goes the code from wp-login.php incl. line-nr.

    216  /**
     217   * Handles resetting the user's password.
     218   *
     219   * @uses $wpdb WordPress Database object
     220   *
     221   * @param string $key Hash to validate sending user's password
     222   * @return bool|WP_Error
     223   */
     224  function reset_password($key, $login) {
     225      global $wpdb;
     226
     227      $key = preg_replace('/[^a-z0-9]/i', '', $key);
     228
     229      if ( empty( $key ) || !is_string( $key ) )
     230          return new WP_Error('invalid_key', __('Invalid key'));
     231
     232      if ( empty($login) || !is_string($login) )
     233          return new WP_Error('invalid_key', __('Invalid key'));
     234
     235      $user = $wpdb->get_row($wpdb->prepare("SELECT * FROM $wpdb->users WHERE user_activation_key = %s AND user_login = %s", $key, $login));
     236      if ( empty( $user ) )
     237          return new WP_Error('invalid_key', __('Invalid key'));
     238
     239      // Generate something random for a password...
     240      $new_pass = wp_generate_password();
     241
     242      do_action('password_reset', $user, $new_pass);
     243
     244      wp_set_password($new_pass, $user->ID);
     245      update_user_option($user->ID, 'default_password_nag', true, true); //Set up the Password change nag.
     246      $message  = sprintf(__('Username: %s'), $user->user_login) . "\r\n";
     247      $message .= sprintf(__('Password: %s'), $new_pass) . "\r\n";
     248      $message .= site_url('wp-login.php', 'login') . "\r\n";
     249
     250      if ( is_multisite() )
     251          $blogname = $GLOBALS['current_site']->site_name;
     252      else
     253          // The blogname option is escaped with esc_html on the way into the database in sanitize_option
     254          // we want to reverse this for the plain text arena of emails.
     255          $blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);
     256
     257      $title = sprintf( __('[%s] Your new password'), $blogname );
     258
     259      $title = apply_filters('password_reset_title', $title);
     260      $message = apply_filters('password_reset_message', $message, $new_pass);
     261
     262      if ( $message && !wp_mail($user->user_email, $title, $message) )
     263            wp_die( __('The e-mail could not be sent.') . "<br />\n" . __('Possible reason: your host may have disabled the mail() function...') );
     264
     265      wp_password_change_notification($user);
     266
     267      return true;
     268  }

    Thanks A LOT!
