Question

我想将数据发送到我的数据库（group_id，user_id和group_name），但只有前两个进入数据库。当我var_dump $groupinvitation->Invitation_group_name = mysql_real_escape_string($groupname);时，它给了我正确的group_name。我究竟做错了什么？

当我用随机词替换'" . $db->conn->real_escape_string($this->Invitation_group_name) . "'时，它运作良好..

PHP

$groupinvitation = new GroupInvitation();

if (isset($_POST["Accept"])) {
    try {
        $group_id = mysql_real_escape_string($_POST["group_id"]);
        $groupinfo = $group->GetGroupInfoByGroupId($group_id);
        $groupname = $groupinfo['group_name'];

        $requestnumber = mysql_real_escape_string($_POST['acceptID']);
        $groupinvitation->AddAsGroupMember($number, $group_id);
        $groupinvitation-> AcceptGroupRequest($requestnumber);
        $groupinvitation->Invitation_group_name = mysql_real_escape_string($groupname);

        $feedback = "Awesome, You just added a friend!";


    } catch(Exception $e) {
        $feedback = $e -> getMessage();

    }
}

声明：

class GroupInvitation
    {

    private $m_sGroup_invitation_group_name;


        public function __set($p_sProperty, $p_vValue)
        {
            switch($p_sProperty)
            {

                case "Invitation_group_name":
                $this->m_sGroup_invitation_group_name = $p_vValue;
                break;

            }
        }

        public function __get($p_sProperty)
        {
            switch($p_sProperty)
            {

                case "Invitation_group_name":
                return $this->m_sGroup_invitation_group_name ;
                break;

            }
        }

功能：

public function AddAsGroupMember($number, $group_id)
        {
                $db = new Db();
                $insert = "INSERT INTO tblgroup_member(


                                group_id,
                                user_id,
                                group_name

                          ) VALUES (

                                '" . $db->conn->real_escape_string($group_id) . "',
                                '" . $db->conn->real_escape_string($number) . "',
                                '" . $db->conn->real_escape_string($this->Invitation_group_name) . "'   



                          )";

                $db->conn->query($insert);


        }

尝试更改

$groupinvitation->AddAsGroupMember($number, $group_id);
$groupinvitation-> AcceptGroupRequest($requestnumber);
$groupinvitation->Invitation_group_name = mysql_real_escape_string($groupname);

到

$groupinvitation->Invitation_group_name = mysql_real_escape_string($groupname);
$groupinvitation->AddAsGroupMember($number, $group_id);
$groupinvitation-> AcceptGroupRequest($requestnumber);

您可以在插入后设置属性。

（不是全部）数据无法到达数据库
