This is the kind of error that I'm facing:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: fetch_data
Filename: pages/instructors.php
Line Number: 126"
Here's my instructor.php line of codes:
<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>
my 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');
}
}
And my model:
class instructor_model extends CI_Model {
function fetch_data(){
$query = $this->db->query("SELECT * FROM instructor ORDER BY ins_id DESC");
return $query;
}
}
Change your controller code as below. It will work. Controller code
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');
}
}
Model Code:-
class instructor_model extends CI_Model {
function fetch_data(){
$query = $this->db->query("SELECT * FROM instructor ORDER BY ins_id DESC");
return $query->result();
}
}
View Code:-
<tr>
<th>ID</th>
<th>Last Name</th>
<th>First Name</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php
if($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>
