Update specific database record in codeigniter - php

Question

Good day, I have some trouble making an update specific record on a selected row from the database. I want to display the data after clicking on the edit icon from the selected data from the table display table.
Controller:
//Show Users/Members page
public function users_page() {
$data['users'] = $this->user->get_users();
$this->load->view('user_page' , $data);
}
Model:
// Retrieve user data from database
public function get_users() {
$this->db->select('id, email, first_name, last_name, date_registered');
$this->db->from('auth_users');
$query = $this->db->get();
$result = $query->result();
foreach ($result as $key => $value) {
// var_dump($key);
$data[$key] = array(
'id' => $value->id,
'firstname' => $value->first_name,
'lastname' => $value->last_name,
'datereg' => $value->date_registered,
'email' => $value->email
);
}
return $data;
}
View:
<table class="table table-condensed">
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
<th>Date Registered</th>
<th>Action</th>
</tr>
<?php foreach($users as $key => $value) {?>
<tr>
<td><?php echo $value['firstname']; ?></td>
<td><?php echo $value['lastname']; ?></td>
<td><?php echo $value['email']; ?></td>
<td><?php echo $value['datereg']; ?></td>
<td><i class="material-icons" title="Click to update">mode_edit</i> |
<i class="material-icons" title="Click to remove">delete</i></td>
</tr>
<?php } ?>
</thead>
<tbody>
</tbody>
</table>

Answer 1

create a new method in your controller, something like this (not exactly like this as I don't know the classes you're already using)
public function show_user($id) {
$data['users'] = $this->user->get_user($id);
$this->load->view('user_page' , $data);
}
create another method in your model, again something like this
public function get_user($id) {
$this->db->select('id, email, first_name, last_name, date_registered');
$this->db->from('auth_users');
$this->db->where('id', $id);
$query = $this->db->get();
$result = $query->result();
$var_dump($result); --or write a view an pass the result to the view
create a form taking the result from the previous (This I cannot write for you)
create an update method in your controller and model (just like you just did to query the information, but now to update the information from this record)
