Question

我正在试图找出为什么当它到达我的控制器中的getLast5Messages函数时它会返回以下内容，但在javascript中的响应中它会放置页面的html。我不明白。

[{"id":"1","subject":"Testing","firstName":"Kevin","lastName":"Smith","dateSent":"March 30th, 2012","messageRead":"0"}]

JS：

function getMessages()
{
$('.mail').empty();
$.get('dashboard/getLast5Messages', function(data)
{
   if(data.length > 0)
    {
        $.each(data, function(x)
        {
            if (data[x]['messageRead'] == 0) 
            {
                $('.mail').append('<li><a href="pmsystem/viewmessage/'+data[x]['id']+'"><strong>Received: '+data[x]['dateSent']+'</strong><small>'+data[x]['subject']+'</small><small>From: '+data[x]['firstName']+' '+data[x]['lastName']+'</small></a></li>'); 
            }
            else
            {
                $('.mail').append('<li class="read"><a href="pmsystem/viewmessage/'+data[x]['id']+'"><strong>Received: '+data[x]['dateSent']+'</strong><small>'+data[x]['subject']+'</small><small>From: '+data[x]['firstName']+' '+data[x]['lastName']+'</small></a></li>');     
            }
        });
    }
    else
    {
        $('.mail').append('<li>No Messages</li>');
    }
}, 'json');
}

PHP：

public function getLast5Messages()
{
    echo $this->pmmodel->getLast5Messages($this->session->userdata('userID'));
}

/**
 * Retrieve last 5 messages in inbox
 *
 * @param   integer
 * @return  object
 */
function getLast5Messages($userID)
{
    // Check args
    if (!is_numeric($userID))
    {
        throw new Exception('Non-numeric $userID provided to getLast5Messages()');
    }

    $this->db->select('pm.id');
    $this->db->select('pm.subject');
    $this->db->select('users.firstName');
    $this->db->select('users.lastName');
    $this->db->select("DATE_FORMAT(pm.dateSent, '%M %D, %Y') AS dateSent", false);
    $this->db->select('pmr.messageRead');
    $this->db->from('usersPersonalMessages AS pm');
    $this->db->join('users', 'users.userID = pm.senderID');
    $this->db->join('usersPersonalMessagesRecipients AS pmr',
        'pm.id = pmr.usersPersonalMessagesID');
    $this->db->where('pmr.userID', $userID);
    $this->db->order_by('pm.dateSent', 'desc');
    $this->db->limit(5);
    $query = $this->db->get();
    if ($query->num_rows() > 0) 
    {
        return $query->result();
    }
    return array();
}

我仍然无法解决这个问题？有谁知道造成这种情况的原因是什么？

是

public function getLast5Messages()
{
    echo json_encode($this->pmmodel->getLast5Messages($this->session->userdata('userID')));
}

没有显示数据数组
