zencart会员登陆保存登陆状态

     zencart会员登陆保存登陆状态，这个功能是非常重要的，也是必要的。我们在zencart会员登陆前台的时候，当我们勾选了记得我。那么我们就可以直接在关闭浏览器的情况下。直接实现zencart自动登陆状态。为了实现这个功能，我们必须对zencart进行二次开发。

   1:首先在zen cart模板增加以下代码。includes/templates/template_default/templates/tpl_login_default.php

    <label class="inputLabel" for="login-password">记得我</label>
<?php echo zen_draw_checkbox_field('remember', '1', false, 'id="remember"');?>

   2:其次在includes/application_top.php里面增加以下代码。

    if(!$_SESSION['customer_id']){
 
 
  if(isset($_COOKIE['zc']['email']) && isset($_COOKIE['zc']['pwd'])){
  
  // Check if email exists
  $check_customer_query = "SELECT customers_id, customers_firstname, customers_lastname, customers_password,
          customers_email_address, customers_default_address_id,
          customers_authorization, customers_referral
          FROM " . TABLE_CUSTOMERS . "
          WHERE customers_email_address = :emailAddress";

  $check_customer_query  =$db->bindVars($check_customer_query, ':emailAddress', $_COOKIE['zc']['email'], 'string');
  $check_customer = $db->Execute($check_customer_query);

  if (!$check_customer->RecordCount()) {
   
  } elseif ($check_customer->fields['customers_authorization'] == '4') {
  
  } else {
    // Check that password is good
    if (!zen_validate_password($_COOKIE['zc']['pwd'], $check_customer->fields['customers_password'])) {
    
    } else {
   if (SESSION_RECREATE == 'True') {
     zen_session_recreate();
   }

   $check_country_query = "SELECT entry_country_id, entry_zone_id
          FROM " . TABLE_ADDRESS_BOOK . "
          WHERE customers_id = :customersID
          AND address_book_id = :addressBookID";

   $check_country_query = $db->bindVars($check_country_query, ':customersID', $check_customer->fields['customers_id'], 'integer');
   $check_country_query = $db->bindVars($check_country_query, ':addressBookID', $check_customer->fields['customers_default_address_id'], 'integer');
   $check_country = $db->Execute($check_country_query);

   $_SESSION['customer_id'] = $check_customer->fields['customers_id'];
   $_SESSION['customer_default_address_id'] = $check_customer->fields['customers_default_address_id'];
   $_SESSION['customers_authorization'] = $check_customer->fields['customers_authorization'];
   $_SESSION['customer_first_name'] = $check_customer->fields['customers_firstname'];
   $_SESSION['customer_last_name'] = $check_customer->fields['customers_lastname'];
   $_SESSION['customer_country_id'] = $check_country->fields['entry_country_id'];
   $_SESSION['customer_zone_id'] = $check_country->fields['entry_zone_id'];

   $sql = "UPDATE " . TABLE_CUSTOMERS_INFO . "
      SET customers_info_date_of_last_logon = now(),
       customers_info_number_of_logons = customers_info_number_of_logons+1
      WHERE customers_info_id = :customersID";

   $sql = $db->bindVars($sql, ':customersID',  $_SESSION['customer_id'], 'integer');
   $db->Execute($sql);
   $zco_notifier->notify('NOTIFY_LOGIN_SUCCESS');

   // bof: contents merge notice
   // save current cart contents count if required
   if (SHOW_SHOPPING_CART_COMBINED > 0) {
     $zc_check_basket_before = $_SESSION['cart']->count_contents();
   }

   // bof: not require part of contents merge notice
   // restore cart contents
   $_SESSION['cart']->restore_contents();
   // eof: not require part of contents merge notice

   // check current cart contents count if required
   if (SHOW_SHOPPING_CART_COMBINED > 0 && $zc_check_basket_before > 0) {
     $zc_check_basket_after = $_SESSION['cart']->count_contents();
     if (($zc_check_basket_before != $zc_check_basket_after) && $_SESSION['cart']->count_contents() > 0 && SHOW_SHOPPING_CART_COMBINED > 0) {
    if (SHOW_SHOPPING_CART_COMBINED == 2) {
      // warning only do not send to cart
      $messageStack->add_session('header', WARNING_SHOPPING_CART_COMBINED, 'caution');
    }
    if (SHOW_SHOPPING_CART_COMBINED == 1) {
      // show warning and send to shopping cart for review
      $messageStack->add_session('shopping_cart', WARNING_SHOPPING_CART_COMBINED, 'caution');
    
    }
     }
   }
   // eof: contents merge notice

   if (sizeof($_SESSION['navigation']->snapshot) > 0) {
     //    $back = sizeof($_SESSION['navigation']->path)-2;
     //if (isset($_SESSION['navigation']->path[$back]['page'])) {
     //    if (sizeof($_SESSION['navigation']->path)-2 > 0) {
     $origin_href = zen_href_link($_SESSION['navigation']->snapshot['page'], zen_array_to_string($_SESSION['navigation']->snapshot['get'], array(zen_session_name())), $_SESSION['navigation']->snapshot['mode']);
     //            $origin_href = zen_back_link_only(true);
     $_SESSION['navigation']->clear_snapshot();
    
   } else {
    
   }
    }
  }

 }

}

    通过这次的zencart二次开发，我们实现了zencart会员登陆保存登陆状态。
