->join('materias','materias.id=cursadas.subject_id')
->WHERE('cursadas.user_id=',$this->session->userdata['id'])
->get()->result_array();
return $st[0];
}

Answer 1

You have the variable $records on view but not on controller
Change
$data['record'] = $this->m_login->getDetails();
To
// add this array() just in case no results found
$data['records'] = array();
$data['records'] = $this->m_login->getDetails();
$this->load->view('usuario', $data);
Another way is on controller
$results = $this->m_login->getDetails();
$data['records'] = array();
if ($results) {
foreach ($results as $result) {
$data['records'][] = array(
'id' => $result['id'],
'User' => $result['User'],
'name' => $result['name'],
'grade' => $result['grade'],
'date' => $result['date']
);
}
}
$this->load->view('usuario',$data);
View
<?php if ($records) {?>
<?php foreach($records as $record) {?>
<tr>
<td><?php echo $record['id'];?></td>
<td><?php echo $record['User'];?></td>
<td><?php echo $record['name'];?></td>
<td><?php echo $record['grade'];?></td>
<td><?php echo $record['date'];?></td>
</tr>
<?php } ?>
<?php } else { ?>
<tr>
<td>No Results Found</td>
</tr>
<?php } ?>

Answer 2

Wrong array index in your controller.
Change this
$data['record']=$this->m_login->getDetails();
to
$data['records']=$this->m_login->getDetails();

Answer 3

result_array() return returns result with array so you need to it like this -
if (count($record) > 0 && $record != false) {
foreach($record as $rec){
echo "<tr>
<td>".$rec['id']."</td>
<td>".$rec['User']."</td>
<td>".$rec['name']."</td>
<td>".$rec['grade']."</td>
<td>".$rec['date']."</td>
</tr>";
}
}
Please check this from above code and comment if you have any problem
