Question

api图层（move_shopping_list.php）：

    if (!isset($_GET['i_sign_in_token'])){
    die(json_encode('Must pass in the i_sign_in_token into the url'));
}

if (!isset($_GET['itm_cd'])){
    die(json_encode('Must pass in itm_cd into the URL'));
}

if (!isset($_GET['list_id_old']) || !isset($_GET['list_id_new'])){
    die(json_encode('Must pass in the list_id_old or new value into the URL'));
}


$list = new ShoppingListItem($_GET['i_sign_in_token'], $_GET['itm_cd'], $_GET['list_id_old'], $_GET['list_id_new']);
$moveItems = $item->move_between_lists($token, $_GET['itm_cd'], $_GET['list_id_old'], $_GET['list_id_new']);

echo json_encode($moveItems);

这是我在ShoppingListItem类中的lists方法之间移动：

    public function move_between_lists($shopper, $new_list_id) {
    global $pd, $db;

    // todo: don't forget to update $this->ShoppingList
    $vars = array();
    $vars[] = array('i_sign_in_token', $shopper);
    $vars[] = array('itm_cd', $this->ITM_CD);
    $vars[] = array('list_id_old', $this->SHOPPING_LIST_ID);
    $vars[] = array('list_id_new', $new_list_id);

    $rows = $db->get_function_as_proc('custom.japi_shopping_list.Move_Bewteen_Lists(:i_sign_in_token, :itm_cd, :list_id_old, :list_id_new)', $vars);

    if ($rows == 'Y') {
        // Must have worked or it would have returned. 
        $this->SHOPPING_LIST_ID = $new_list_id;

        return true;
    } else { 
        return false;
    }


}

我一直收到这些错误，我不知道为什么......任何帮助都会非常感激。

如果未设置$ _GET中的数组键，则显式检查此不存在的键是否也不是空字符串。逻辑错误，您不能使用&&（和）||（或）。

在api层上返回json编码我收到以下错误
