Codeigniter从数据库问题中删除

I am new to codeigniter, I have managed to get insert working into the database and I have done the code to delete from the database however when clicking on the job to delete it, it just refreshes and the job is still in the database.

My Controller

public function deleteclientform(){
    $this->load->helper('form');
    $this->load->model("clientmodel"); 
    $data['clients']=$this->clientmodel->getallclients();
    $data['title']="Delete Job";
    $this->load->view("deleteclientform",$data); 
}

public function delete(){
    $films=$this->input->post('clients');
    $this->load->model("clientmodel");
    foreach($clients as $jobno)
    {
        $this->clientmodel->deleteclient($jobno);
    }
     redirect('/nav/home', 'refresh');
}

My Model

function deleteclient($jobno)

{
$this->db->where('jobno', $jobno);
$result=$this->db->delete('client');
return $result;
}

My View

echo form_open('client/delete');

foreach($clients as $client)
{
echo "<p>";
echo form_label($client->job, 'client'.$client->jobno);
$data = array('name' => 'clients[]', 'jobno'=>'client'.$client->jobno, 'value' =>    $client->jobno);
echo form_checkbox($data);
echo "</p>";
}
echo form_submit("delete_btn","Delete these Jobs");
echo form_close();

public function delete(){
    $films=$this->input->post('clients');
    $this->load->model("clientmodel");
    foreach($films as $jobno)
              ^ this
    {
        $this->clientmodel->deleteclient($jobno);
    }
     redirect('/nav/home', 'refresh');
}

This function in your controller was wrong.

You were referring to $clients when it was $films you wanted.
