PHP - 我在codeigniter中遇到数组到字符串转换错误

标签： php arrays string codeigniter

我试图在我的系统中有一个编辑/更新模块。但是，似乎我无法弄清楚为什么我得到数组到字符串转换错误。以下是模型，视图，控制器代码。

模型中的线错误

function updatebyid($userid, $data)
{
    $this->db->where('id', $userid); **i get the error in this line in my model**

控制器中的线路错误

$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
    if ($this->model_user->updatebyid($userid, $data)) **AND IN THIS LINE TOO IN MY CONTROLLER**

我的模特

function get_user_by_id($id)
{
    $this->db->where('id', $id);
    $query = $this->db->get('users');
    return $query->result();
}
function updatebyid($userid, $data)
{
    $this->db->where('id', $userid);
    $query = $this->db->update('users', $data);
    return $query->result();
    //return $query->row()->query;
}

我的观点

</div>
    <div class="row well" style="color: black; margin-top: 15px;">
        <h2>Edit Profile</h2>
            <?php $attributes = array("name" => "registerform");
        echo form_open("account/edituserinfo/", $attributes);?>

        <div class="form-group">

            <div class="col-sm-4">
            <label for="fname">First Name</label>
            <input class="form-control" name="fname" required type="text" value="<?php echo $fname; ?>" />
            <span class="text-danger"><?php echo form_error('fname'); ?></span>
            </div>

            <div class="col-sm-4">
            <label for="mname">Middle Name</label>
            <input class="form-control" name="mname" required placeholder="Middle Name" type="text" value="<?php echo $mname; ?>" />
            <span class="text-danger"><?php echo form_error('mname'); ?></span>
            </div>

            <div class="col-sm-4">
            <label for="lname">Last Name</label>
            <input class="form-control" name="lname" required placeholder="Last Name" type="text" value="<?php echo $lname; ?>" />
            <span class="text-danger"><?php echo form_error('lname'); ?></span>
            </div>
        </div>
<div class="input-group" style="padding-top: 15px; margin-left: 15px">
            <button name="submit" type="submit" class="btn btn-success">Update</button>
            <!--input class="form-control" name="id" placeholder="id" type="hidden" value="<?php echo $id; ?>" /-->
        </div>

        <?php echo form_close(); ?>
        <?php echo $this->session->flashdata('msg'); ?>
    </div>
    </div>

我的控制器

function index()
{
    $this->load->view('include/headnav');
    $details = $this->model_user->get_user_by_id($this->session->userdata('id'));
    $data['name'] = $details[0]->fname . " " . $details[0]->lname;
    $data['level'] = $this->session->userdata('level');
    $data['fname'] = $details[0]->fname;
    $data['mname'] = $details[0]->mname;
    $data['lname'] = $details[0]->lname;
    $data['gender'] = $details[0]->gender;
    $data['email'] = $details[0]->email;
    $data['mobileNum'] = $details[0]->mobileNum;

    //$data['institutionNum'] = $details[0]->institutionNum;
    $this->load->view('view_account', $data);
    $this->load->view('include/footernav');
}
function edituserinfo()
{
    $this->load->view('include/headnav');

    $data = array(
            'lname' => $this->input->post('lname'),
            'fname' => $this->input->post('fname'),
            'mname' => $this->input->post('mname'),
            'gender' => $this->input->post('gender'),
            'homeaddress' => $this->input->post('homeaddress'),
            'mobileNum' => $this->input->post('mobileNum'),
            //'password' => $this->input->post('password'),

            //'position' => $this->input->post('position'),
        );

    $userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
    if ($this->model_user->updatebyid($userid, $data))
        {

            $this->session->set_flashdata('msg','<div class="alert alert-success text-center">Profile edited.</div>');
            redirect('account/edituserinfo');
        }
        else
        {
            // error
            $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Error. Check credentials.</div>');
            redirect('account/edituserinfo');
        }
}

    function updateuinfoview()
{
    $this->load->view('include/headnav');
    $details = $this->model_user->get_user_by_id($this->session->userdata('id'));
    //$data['fname'] = $details[0]->fname . " " . $details[0]->lname;
    $data['fname'] = $details[0]->fname;
    $data['lname'] = $details[0]->lname;
    $data['mname'] = $details[0]->mname;
    $data['gender'] = $details[0]->gender;
    $data['email'] = $details[0]->email;
    $data['mobileNum'] = $details[0]->mobileNum;
    $data['landlineNum'] = $details[0]->landlineNum;
    $data['homeaddress'] = $details[0]->homeaddress;

    //$data['institutionNum'] = $details[0]->institutionNum;
    $this->load->view('view_editprofile', $data);
    $this->load->view('include/footernav');
}

3 个答案:

答案 0 :(得分：1)

您正在获得数组到字符串转换错误，因为您的模型：

$this->model_user->get_user_by_id($this->session->userdata('id'))

返回一个对象数组。要解决您的问题，您可以循环结果     或者如果您只需要结果的第一行，您可以这样做：

$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
if ($this->model_user->updatebyid($userid[0]->id, $data))

或者您可以像这样修改模型：

function get_user_by_id($id)
{
    $this->db->where('id', $id);
    $query = $this->db->get('users');
    return $query->row(); // use row if you only want the first row of the result of your query
}

<强>控制器：

$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
if ($this->model_user->updatebyid($userid->id, $data))

*************** ****************************************
或者更全面的模型，这样您就不需要更换控制器了：

function get_user_by_id($id)
{
    $this->db->where('id', $id);
    $query = $this->db->get('users');
    $result = $query->row();
    return ($result) ? $result->id : false; 
}

答案 1 :(得分：0)

您正在更新

中传递用户详细信息数组而不是用户ID

更改此行

$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));

到

$userid = $this->session->userdata('id');

在控制器的function edituserinfo()中

答案 2 :(得分：0)

$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));

在上面一行中，您将查询将返回数组的数据库。

而是将用户ID设置为

$userid = $this->session->userdata('id');
