ecshop之实现取消收藏功能

找到根目录下面的 user.php

/* 添加收藏商品(ajax) */
elseif ($action == 'collect')
{
include_once(ROOT_PATH .'include/cls_json.php');
$json = new JSON();
$result = array('error' => 0, 'message' => '');
$goods_id = $_GET['id'];

if (!isset($_SESSION['user_id']) || $_SESSION['user_id'] == 0)
{
$result['error'] = 1;
$result['message'] = $_LANG['login_please'];
die($json->encode($result));
}
else
{
/* 检查是否已经存在于用户的收藏夹 */
$sql = "SELECT COUNT(*) FROM " .$GLOBALS['ecs']->table('collect_goods') .
" WHERE user_id='$_SESSION[user_id]' AND goods_id = '$goods_id'";
if ($GLOBALS['db']->GetOne($sql) > 0)
{
$result['error'] = 1;
$result['message'] = $GLOBALS['_LANG']['collect_existed'];
die($json->encode($result));
}
else
{
$time = gmtime();
$sql = "INSERT INTO " .$GLOBALS['ecs']->table('collect_goods'). " (user_id, goods_id, add_time)" .
"VALUES ('$_SESSION[user_id]', '$goods_id', '$time')";

if ($GLOBALS['db']->query($sql) === false)
{
$result['error'] = 1;
$result['message'] = $GLOBALS['db']->errorMsg();
die($json->encode($result));
}
else
{
$result['error'] = 0;
$result['message'] = $GLOBALS['_LANG']['collect_success'];
die($json->encode($result));
}
}
}
}
//新增取消搜藏
elseif ($action == 'uncollect')
{
include_once(ROOT_PATH .'include/cls_json.php');
$json = new JSON();
$result = array('error' => 0, 'message' => '');
$goods_id = $_GET['id'];

if (!isset($_SESSION['user_id']) || $_SESSION['user_id'] == 0)
{
$result['error'] = 1;
$result['message'] = $_LANG['login_please'];
die($json->encode($result));
}
else
{
/* 检查是否已经存在于用户的收藏夹 */
$sql = "delete  FROM " .$GLOBALS['ecs']->table('collect_goods') .
" WHERE user_id='$_SESSION[user_id]' AND goods_id = '$goods_id'";

if ($GLOBALS['db']->query($sql) === false)
{
$result['error'] = 1;
$result['message'] = $GLOBALS['db']->errorMsg();
die($json->encode($result));
}
else
{
$result['error'] = 3;
$result['message'] = '恭喜您成功取消搜藏！';
die($json->encode($result));
}

}
}

在collect函数下面添加 uncollect 即可实现 关于语言包的问题可以 $_LANG[‘login_please’]

去语言包中添加变量来替代‘恭喜您成功取消搜藏！’ 这句话。也便于以后拓展。
