PHP foreach使用通过ajax请求发送的数组失败.发送给函数的正确数据 - PHP foreach using an array sent via an ajax request failing. Correct data sent to function

PHP foreach using an array sent via an ajax request failing. Correct data sent to function

在ajax请求中，我发送一个member_id数组，以便返回屏幕名称。成员id存储如下：

var member_id = [];
    Ext.each(selected_rows, function(item) {
        member_id.push(item.data.member_id);
    });

然后我将它们发送到retrieve_members函数

Ext.Ajax.request({
                    action: 'retrieve_members',
                    member_id: member_id,
                    success_fn: function(response) {
                    //do stuff
                    }
                }); //end ajaxRequest

Firebug在发送呼叫时显示此信息：

action  retrieve_members
member_id   45FA3B10-4546-B9F7-D23
member_id   9627B65B-4D82-B2E8-4CE

在retrieve_members函数中：

function retrieve_members($request) {
$member_ids = substr($request->member_id,0,-1);
    foreach($member_ids as $member_id) {
        $current_member = Member::retrieveById($request->db, $member_id);
        $member_list = $current_member->getGroupMembers();
        $members = array();
        foreach ( $member_list as $member ) {
            $member_list[] = array(
                'id' => $member->id,
                'screen_name' => $member->screen_name,
            );
        }
    }
return json_encode(array('status' => 'OK', 'member_list' => $member_list));
}

如果我删除foreach并替换以下行：

$member = Member::retrieveById($request->db, $request->$member_id);

我得到了1个成员的正确数据。我知道"substr（$request->member_id，0，-1）；"可能是错误的，但我已经多次尝试将正确的member_ids传递给foreach。我不确定我做错了什么，但就目前情况来看，member_list将始终返回null。感谢您的帮助！

更新：print_r（$request->member_id）；返回以下错误：

identifier starts immediately after numeric literal
[Break On This Error]   
(9627B65B-4D82-B2E8-4CE)

您似乎正在覆盖一些变量。也许试试：

function retrieve_members($request) {
$member_ids = substr($request->member_id,0,-1);
    foreach($member_ids as $member_id) {
        $member = Member::retrieveById($request->db, $member_id);
        $member_list = $member->getGroupMembers();
        $members = array();
        foreach ( $member_list as $tempMember ) {
            array_push($members,array(
                'id' => $tempMember->id,
                'screen_name' => $tempMember->screen_name,
            ));
        }
    }
return json_encode(array('status' => 'OK', 'member_list' => $members));
}
