无法显示有关用户的详细信息（codeigniter）

Question

我的代码无法显示有关我选择的一个用户的详细信息，它总是显示有关桌子上最后一个用户的详细信息，无论我点击谁。 我认为我的问题是我的代码无法意识到我点击了谁，所以它只选择了最后一个用户。你能看看并帮我解决我的问题。 这是我的观点（我在引导模式上使用模式来显示结果）

<div class="modal fade" id="userDetail" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="exampleModalLabel"><span class = "glyphicon glyphicon-pencil"></span> Edit</h4>
    </div>
    <div class="modal-body">
      <div class="form-group">
        <?php echo form_open('admin/update_event'); ?>

        <select class = "form-control">
            <option selected disabled><?php if($r->level==1){
                    echo 'Admin';
                }else{
                    echo 'Member';
                } ?></option>
            <option value="1" <?php echo ($r->level == 1)?:""; ?>>Administrator</option>
            <option value="0" <?php echo ($r->level == 2)?:""; ?>>Member</option>

                    echo 'Deactive';
                }else{
                    echo 'Active';
                } ?></option>
            <option value="1" <?php echo ($r->sta == 1)?:""; ?>>Deactive</option>
            <option value="0" <?php echo ($r->level == 0)?:""; ?>>Active</option>
        </select></p>

    </div>
</div>
<div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    <input type = "submit" value = "Update" class = "btn btn-primary">
    <?php echo form_close();?>
</div>

这是我的代码：

   <?php 
$count = 1;

foreach ($ro as $r) 
{
    ?>
    <tr>
        <td scope="row"><?php echo $count++?></td>

        <td>
            <a href="#"  data-toggle="modal" data-target="#userDetail">
                <?php echo $r->username; ?>
            </a>
        </td>
        <td><?php echo $r->email; ?></td>
        <td><?php echo $r->firstname; ?></td>
        <td><?php echo $r->lastname; ?></td>
        <td><?php $r->level; 
            if($r->level==1){
                echo '<strong><p style="color:#0047b3;">Admin</p></strong>';
            }else{
             echo '<strong><p style="color:#993300;">Member</p></strong>';
         }
         ?></td>
     </tr>
     <?php
 }
 ?>

这是我的控制器

function admins_area(){
    $data['main_content'] = 'backend/home/admins_area';
    $this->load->model('membership_model');
    $data['rows']= $this->membership_model->getUserData();
    $data['ro']= $this->membership_model->getAllUserData();
    $this->load->view('includes/admin/template', $data);
}

这是我的模型

function getUserData(){
    $this->db->where('username', $this->session->userdata('username'));
    $query = $this->db->get('user');
    if($query->num_rows()>0){
        foreach ($query->result() as $row){
            $data[]=$row;
        }
        return $data;
    }
}
function getAllUserData(){
    $query = $this->db->get('user');
    if($query->num_rows()>0){
        foreach ($query->result() as $row) {
            $data[]=$row;
        }
        return $data;
    }
}

嘿，在您的控制器中创建一个名为 Modal.php 的文件并将此代码粘贴到其中

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Modal extends CI_Controller {


    function __construct()
    {
        parent::__construct();
        $this->load->database();        
        $this->load->helper(array('form', 'url'));
        /*cache control*/
        $this->output->set_header('Last-Modified: ' . gmdate("D, d M Y H:i:s") . ' GMT');
        $this->output->set_header('Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0');
        $this->output->set_header('Pragma: no-cache');
        $this->output->set_header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); 
    }

    /***default functin, redirects to login page if no admin logged in yet***/
    public function index()
    {

    }


    /*
    *   $page_name      =   The name of page
    */
    function popup($page_name = '' , $param2 = '' , $param3 = '')
    {
        //$account_type             =   $this->session->userdata('login_type');
        $page_data['param2']        =   $param2;
        $page_data['param3']        =   $param3;
        $this->load->view( $page_name.'.php' ,$page_data);
    }
}

和 这是查看所有用户

<?php 
$count = 1;

foreach ($ro as $r) 
{
    ?>
    <tr>
        <td scope="row"><?php echo $count++?></td>

        <td>
                <?php echo $r->username; ?>
        </td>
<td>
<button onclick="showAjaxModal('<?php echo site_url(); ?>/modal/popup/details/<?php echo $r->username; ?>')">Details</button>
</td>
</tr><?php } ?>

还有一些html

 <div class="modal fade" id="modal_ajax" data-backdrop="static" data-keyboard="false">
        <div class="modal-dialog" >
            <div class="modal-content">

                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                    <h4 class="modal-title">User Details</h4>
                </div>

                <div class="modal-body">



                </div>

                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>

还有一些javascript

<script>
function showAjaxModal(url)
    {
        // SHOW AJAX RESPONSE ON REQUEST SUCCESS
        jQuery.ajax({
            url: url,
            success: function(response)
            {
                jQuery('#modal_ajax .modal-body').html(response);                         
                jQuery('#modal_ajax').modal('show', {
                  backdrop: 'static',
                  keyboard: false
                });

            }
        });
    }
</script>

最后在你的 application/views 文件夹中创建一个名为 details.php 的文件并写入

<?php
$this->db->where('username', $param2);
    $query = $this->db->get('user');

$details = $query->row();

print_r($details);
?>
