Delete row in database using CodeIgniter

Question

Why is it not deleting? When I press delete, I should get the id of the row that I will delete.

View:

<?php
foreach ($cust_data as $row) {
    echo '<tr class="even pointer">';
    echo '<td class="a-center ">';
    echo '<input type="checkbox" class="tableflat">';
    echo '</td>';
    echo'<td>' . $row->cust_id . '</td>';
    echo'<td>' . $row->firstname . '</td>';
    echo'<td>' . $row->lastname . '</td>';
    echo'<td>' . $row->email . '</td>';
    echo'<td>' . $row->contact_number . '</td>';
    echo'<td>' . $row->address . '</td>';
    echo'<td>';
    echo '<a href="' . base_url() . 'administrator/delete?id=' . $row->cust_id . '">Delete</a>';
    echo'</td>';
    echo'</tr>';
}
?>    

Model:

public function delete($id) {
    $this->db->delete('customer', array('cust_id' => $id));
}

Controller:

public function delete() {
    $this->load->model('admin_model');
    $this->admin_model->delete($this->input->get('cust_id'));
    $this->customer();
}

I have noticed that you used to post the value of id in your code:

echo '<a href="' . base_url() . 'administrator/delete?id=' . $row->cust_id . '">Delete</a>';

while on your controller you used the get() using the name of cust_id :

$this->admin_model->delete($this->input->get('cust_id'));

you cannot get any value because cust_id is not the name of the posted value. so change your cust_id to id like the example below:

public function delete() {
    $this->load->model('admin_model');
    $this->admin_model->delete($this->input->get('id'));
    $this->customer();
}
