Returning to update form after validation
#11

OK, I've got the model working with the perameter s you suggest but the form actions update_user() and within this function, there is no reference to the userid?
I think I'm back where I started sort of but this time I'm getting Undefined variable: user
Here's the complete code:
Controller:
Code:
<?php
class Users extends Controller {
    // Display create admin user form
    function create_admin ()
    {
        $data['title'] = 'Create admin users';
        $data['admins'] = $this->users_model->get_admin_users(); // get list of admin users
        $this->load->view('includes/header',$data);
        $this->load->view('admin/users/users_view',$data);
        $this->load->view('admin/users/create_admin_view',$data);    
        $this->load->view('includes/footer',$data);
    }
    // Add new user
    function add_user()
    {
        $this->form_validation->set_rules('username', 'Username', 'required');
        $this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]');
        $this->form_validation->set_rules('passconf', 'Retype password', 'required');
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email');
        
        if($this->form_validation->run()==FALSE)
        {
            $this->create_admin();
        }
        else
        {
        $data = array(
            'username'    =>$this->input->post('username'),
            'password'     =>$this->input->post('password'),
            'firstname' =>$this->input->post('firstname'),
            'lastname'     =>$this->input->post('lastname'),
            'email'        =>$this->input->post('email'),
            'dateadded'    =>$this->input->post('dateadded')
            );
            $this->users_model->create_user($data);
            $this->index();
        }    
    }
    // Display update user form
    function update_admin_form()
    {
        $data['title'] = 'Update admin user';
        $data['admins'] = $this->users_model->get_admin_users(); // get list of admin users
    
          if($this->uri->segment(4))
        {
            $data['user'] = $this->users_model->get_user($this->uri->segment(4));
        }
        $this->load->view('includes/header',$data);
        $this->load->view('admin/users/users_view',$data);
        $this->load->view('admin/users/update_admin_view',$data);

            return $data;

[eluser]flaky[/eluser]
change
Code:
function update_admin_form()
{
to
Code:
function update_admin_form($user_id=null)
{

then change

Code:
if($this->uri->segment(4))
{

to

Code:
if($user_id != null)
{
    $data['user'] = $this->users_model->get_user($user_id);
}


this

Code:
function update_admin_form()
    {
        $data['title'] = 'Update admin user';
        $data['admins'] = $this->users_model->get_admin_users(); // get list of admin users
    
          if($this->uri->segment(4))
        {
            $data['user'] = $this->users_model->get_user($this->uri->segment(4));
        }
        $this->load->view('includes/header',$data);
        $this->load->view('admin/users/users_view',$data);
        $this->load->view('admin/users/update_admin_view',$data);    
        $this->load->view('includes/footer',$data);
    }

change to

Code:
function update_admin_form()
    {
        $data['title'] = 'Update admin user';
        $data['admins'] = $this->users_model->get_admin_users(); // get list of admin users
    
          if($this->uri->segment(4))
        {
            $data['user'] = $this->users_model->get_user($this->uri->segment(4));
            $this->load->view('admin/users/update_admin_view',$data);
        }
        $this->load->view('includes/header',$data);
        $this->load->view('admin/users/users_view',$data);
          
        $this->load->view('includes/footer',$data);
    }

Thanks flaky,

I'm really sorry that's confused me. What do I need to change in the update_admin_form function?

Your last change here seems to overwrite the prvious one?

Thanks,
#17

[eluser]Loquela[/eluser]
Code:
&lt;?php echo form_open('admin/users/update_user/' . $user->userid);?&gt;

This actually does get rid of the errors and on submit I am returned to the form and the values from the selected row are inserted!

HOWEVER, the form does not update the record if I change the valuse in the fields and the validation doesn't work!

I THINK we're getting somewhere but not quite there yet...

Anymore thoughts flaky?

Cheers

[eluser]flaky[/eluser]
do after update_user to check if the values have been updated in the array
Code:
else
        {
            $this->users_model->update_user($data);
            print_r($data);
            $this->update_admin_form($data);
        }
#19

[eluser]flaky[/eluser]
found the little bug
in the controller you have it like this
Code:
else
        {
            $this->users_model->update_user($data);
            $this->update_admin_form($data);
        }

while in the model

Code:
function update_user($user_id)
    {
        $this->db->where('userid', $user_id );
        $this->db->update('pp_users', $data);    
        return;
    }

change them to this


in the controller
Code:
else
        {
            $this->users_model->update_user($this->uri->segment(4), $data);
            $this->update_admin_form($data);
        }


in the model
Code:
function update_user($user_id, $data)
    {
        $this->db->where('userid', $user_id );
        $this->db->update('pp_users', $data);    
        return;
    }

Thanks a lot flaky!
I'll get back to you as soon as I get a chance to look at this.
