Edit form echoes previously saved data correctly but does not update the form fields

问题

Echoing previously saved data (excluding those from dropdown values) already works fine for me. I could see correct data saved for a particular record, however, after editing the form, I don't see anything successful after it. The data which were supposedly edited remain the same. Everything I typed to actually edit the echoed values went nowhere.

I currently have this in my controller:

    public function edit_job() 
{
    $this->validateRole('client');
    $this->load->model('job_model');

    $id = $this->uri->segment(3,0);

    $data['my_preference'] = $this->array_to_select( $this->job_model->get_all_categories(), 'id','name');
    $data['job'] = $this->job_model->get_job($id);
    $this->load->view('client/edit_job', $data);
}   

public function edit_job_submit() 
{
    $this->validateRole('client');
    $this->load->model('job_model');

    if ( '0' != $_POST['id'] ) 
    {
        $this->job_model->edit_job($_POST);
    } else {
        $this->job_model->add_job($_POST);
    }
    redirect('client/manage_jobs?message=Job updated.');
}

While I have this in my model:

public function edit_job($obj)
{
    $data = array
    (
        'title' => $post_obj['title'],
        'description' => $post_obj['description'],
        'start_date' => date("Y-m-d", strtotime($post_obj['start_date'])),
        'category_id' => $post_obj['category_id']
    );
    $this->db->where('id', $id);
    $this->db->update('job', $data);    
}

回答1:

i think your problem is with this : redirect('client/manage_jobs?message=Job updated.'); instead use something like $this->load->view('success');

create a view called success and write a message saying success. put it after the update/insert function

Hope this helps

I had to add $id = $obj['id']; to update particular entry attempted to be edited
