I'；我正在开发一个php购物清单函数/api

返回购物列表对象的数组，对于购物者或具有“建议”标志='Y'的列表

当我手动将令牌添加到$\u GET时，返回的是一个空白数组<代码>[{}，{}] 但如果我使用var_dump（$shopper_list），我会得到两个不同的用户列表。。它应该只有一个，因为一个登录应该等于一个令牌：

[{},{}]
array(2) {
  [0]=>
  object(UserShoppingList)#4 (14) {
    ["sign_in_token":protected]=>
    NULL
    ["Shopper":protected]=>
    NULL
    ["ID":protected]=>
    string(1) "4"
    ["SHOPPING_LIST_NAME":protected]=>
    string(18) "kj's shopping list"
    ["SUGGESTION":protected]=>
    string(1) "N"

    array(0) {
    }
    ["alias_php_to_db":"Base":private]=>
    array(0) {
    }
  }
  [1]=>
  object(UserShoppingList)#5 (14) {
    ["sign_in_token":protected]=>
    NULL
    ["Shopper":protected]=>
    NULL
    ["ID":protected]=>
    string(1) "2"
    ["SHOPPING_LIST_NAME":protected]=>
    string(20) "bonner shopping list"
    ["SUGGESTION":protected]=>
    string(1) "N"
    ["SEQUENCE":protected]=>
    NULL
    ["ShoppingListItem":protected]=>
    NULL
    ["api_url":protected]=>
    NULL
    ["table":"Base":private]=>
    string(23) "jfw_shopping_list_names"
    ["procedure":"Base":private]=>

    array(0) {
    }
    ["alias_php_to_db":"Base":private]=>
    array(0) {

  }
}

我的php页面（get_shopping_lists.php）如下所示：

/*
    This script is used to return a JSON array of ShoppingList objects.
    Those objects can be limited to either only "suggested" ShoppingList names,
    or to all of the lists for a single Shopper.  So, either the shopper_id or
    the boolean "suggested_only" should be set.
*/
if(!isset($_GET['token']) && !isset($_GET['suggested_only'])) {
    die('Must pass-in either a \'token\' or \'suggested_only\' flag');
}

if(isset($_GET['token'])) {
    $shopper = new Shopper($_GET['token'])
    or die('Could not instantiate a new Shopper from the \'token\' passed-in');

    $shopper_lists = $shopper->get_lists(true);
    echo json_encode($shopper_lists);
}

if(isset($_GET['suggested_only']) && $_GET['suggested_only'] == 'true') {

}

我希望返回一个购物列表对象数组，或者是一个购物者（在这里，您将向购物者类的“get_lists”函数传递一个令牌），或者如果您要传递另一个参数表示您只想要建议的列表，则返回具有“sugged”标志='Y'的列表。这些选项中的每一个都会对框架中的各个部分进行不同的调用

和往常一样，任何帮助或建议都将不胜感激。谢谢。

基于该购物者类，更新后的get\u list函数正在调用db方法：

$rows = $db->get_function('custom.japi_shopper_identity.get_lists_for_shopper(:i_sign_in_token)', $vars);

此方法返回一个数组，我必须假设该数组是来自oracle数据库的查询结果。将其转换为一组对象并返回到get_shopping_lists.php后，需要检查以确保该值不为false，因为这是get_lists（）方法调用中的最终else条件。如果是，则输出某种类型的错误消息（如果您的消费者期望的是JSON格式，则可能是JSON格式）

至于你想增加的新东西

• 如果没有列表，则自动创建列表，并且
• 获取建议列表

对于第一个，在获取行之后，您将检查以确保$rows不是空的，然后调用一个方法来创建列表（可能也是oracle端的某种类型的customer.japi_shopper…函数）

---

对于第二种情况，您将使用if/else（if$suggered==true，获取这些结果；否则，执行您已经在做的事情……）来分支逻辑

你能发布Shopper类的完整代码吗？一旦你用一个令牌实例化该类，就不清楚它们的列表是如何填充的。根据上面的代码，你创建一个新的Shopper对象，然后调用get_lists（），它只获取UserShoppingList中已经存在的内容。你要么需要在类构造中加载它，要么调用get_lists（）我现在发布了整个Shopper类。谢谢你的回复，但我还是有点困惑Chris。我应该在Shopper类中构建这两个函数，还是将它们添加到我的get_shopping_lists.php页面？现在我一直在收到死亡消息。。。“必须输入‘令牌’或‘仅建议’标志”给我发一封电子邮件，我们可以通过这种方式进行讨论，或者我可以跳转到IRC。电子邮件在我的个人资料中。电子邮件已发送。感谢您一直与我在一起。

$rows = $db->get_function('custom.japi_shopper_identity.get_lists_for_shopper(:i_sign_in_token)', $vars);
