这是我面临的错误:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: fetch_data
Filename: pages/instructors.php
Line Number: 126"
这是我的 coach.php 代码行:
<tr>
<th>ID</th>
<th>Last Name</th>
<th>First Name</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php
if($fetch_data) {
foreach ($fetch_data->result() as $row) {
?>
<tr>
<td><?php echo $row->ins_id; ?></td>
<td><?php echo $row->lastname; ?></td>
<td><?php echo $row->firstname; ?></td>
<td><a class="btn btn-info" href="<?php echo base_url('Edit_faculty'); ?>">Edit</a></td>
</tr>
<?php
}
}
else
{
?>
<tr>
<td colspan="3">No data found</td>
</tr>
<?php
}
?>
</tbody>
</table>
我的 Controller :
class Add_instructor extends CI_Controller{
public function instructor(){
$this->load->model('instructor_model');
$data["fetch_data"] = $this->instructor_model->fetch_data();
$this->load->vars($data);
$this->load->view('templates/header');
$this->load->view('pages/add_instructor', $data);
$this->load->view('templates/footer');
}
}
还有我的模型:
class instructor_model extends CI_Model {
function fetch_data(){
$query = $this->db->query("SELECT * FROM instructor ORDER BY ins_id DESC");
return $query;
}
}
最佳答案
如下更改您的 Controller 代码。它会起作用的。 Controller 代码
class Add_instructor extends CI_Controller{
public function instructor(){
$this->load->model('instructor_model');
$data["fetch_data"] = $this->instructor_model->fetch_data();
$this->load->view('templates/header');
$this->load->view('pages/instructor', $data);
$this->load->view('templates/footer');
}
}
型号代码:-
class instructor_model extends CI_Model {
function fetch_data(){
$query = $this->db->query("SELECT * FROM instructor ORDER BY ins_id DESC");
return $query->result();
}
}
查看代码:-
<tr>
<th>ID</th>
<th>Last Name</th>
<th>First Name</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php
if($fetch_data) {
foreach($fetch_data as $row) {
?>
<tr>
<td><?php echo $row->ins_id; ?></td>
<td><?php echo $row->lastname; ?></td>
<td><?php echo $row->firstname; ?></td>
<td><a class="btn btn-info" href="<?php echo base_url('Edit_faculty'); ?>">Edit</a></td>
</tr>
<?php
}
}
else
{
?>
<tr>
<td colspan="3">No data found</td>
</tr>
<?php
}
?>
</tbody>
