我正在尝试制作更新表单，它将检索所选特定 ID 的数据，并填写表单，以便其可用于更新。 按下按钮后，我收到错误 “ undefined variable 结果” 和 “尝试获取非对象的属性”
以下是我的代码。
主视图
<form action="<?php echo base_url();?>index.php/validation_control/addnew" method="post">
<table align="center" border=2>
<tr>
<th>id</th>
<th>Username</th>
<th>Firstname</th>
<th>Lastname</th>
<th>Image</th>
<th>Email</th>
<th>Birt Date</th>
<th>Status</th>
<th>Edit</th>
</tr>
<?php
foreach ($query as $row)
{
$style='';
if($row->status=='deactive'){$style = 'style="text-decoration: line-through"';}
?>
<tr <?php echo $style;?>>
<td><?php echo $row->id; ?></td>
<td><?php echo $row->username; ?></td>
<td><?php echo $row->fname; ?></td>
<td><?php echo $row->lname; ?></td>
<td><?php echo "<img src='../codeigniter/uploads/".$row->userfile."' width=30 height=30>";?></td>
<td><?php echo $row->email; ?></td>
<td><?php echo $row->bdate; ?></td>
<td>
<a href="<?php echo base_url('index.php/validation_control/update_status');?>/<?php echo $row->id;?>/<?php echo $row->status; ?>" ">
<?php echo $row->status;?></a>
</td>
<td><a href="<?php echo base_url('index.php/validation_control/edit');?>/<?php echo $row->id;?>">Edit</a></td>
</tr>
<?php
}
?>
<tr><td align="center" colspan="8"><input type="submit" value="Add New" /> </td></tr>
</table>
</form>

控制
function edit($member_id)
{
$member = $this->validation_model->get_member($member_id);
//$this->load->view('validation_edit', $member);
$this->load->view('validation_edit',array('result'=>$member));
}
function edit_member($member_id=NULL)
{
//$product = $this->validation_model->get_member($member_id);
// $this->data['title'] = 'Edit Member';
//validate form input
$this->form_validation->set_rules('uname', 'Username', 'required|is_unique[validation.username]');
$this->form_validation->set_rules('fname', 'Firstname', 'required|min_length[2]');
$this->form_validation->set_rules('lname', 'Lastname', 'required|min_length[2]');
$this->form_validation->set_rules('phone', 'Phonenumber', 'required|max_length[10]|is_natural|valid_base64');
$this->form_validation->set_rules('pass', 'Password', 'required');
$this->form_validation->set_rules('cnfpass', 'Password Confirmation', 'required|matches[pass]');
$this->form_validation->set_rules('status', 'Status', 'required');
$this->form_validation->set_rules('email', 'Email', 'required|valid_email');
// echo "calling"; exit;
if ($this->form_validation->run() == FALSE)
{
$this->load->view('validation_edit');
}
else
{
$image_path = $this->upload->data();
$data = array(
'username'=>$this->input->post('uname'),
'fname'=>$this->input->post('fname'),
'lname'=>$this->input->post('lname'),
'phone'=>$this->input->post('phone'),
'email'=>$this->input->post('email'),
'password'=>$this->input->post('pass'),
'bdate'=>$this->input->post('date'),
'status'=>$this->input->post('status'),
'userfile'=>$_FILES['userfile']['name']
//'userfile' => $image_path[name]
);
$this->validation_model->update_member($data);
echo $data;
}
//redirect();
// $this->load->view('validation_edit', $this->data);
}
型号
public function update_member($data)
{
$this->db->where('id', $member_id);
$this->db->update('validation', $data);
}
最佳答案
在你的 Controller 中尝试使用这个:
function edit($member_id)
{
$data['result'] = $this->validation_model->get_member($member_id);
$this->load->view('validation_edit',$data);
}
