Hi

I have tried to test validation with rule to see if record are in the database before create a new record. This works as expected.

But I can't update a row when the rule are enabled in the code. Any idea why it stop with the loading message (see picture)
[sharedmedia=core:attachments:320]


Here are my code:

public function employees()
{
$crud = new grocery_CRUD();

$crud->set_subject('Employee');
$crud->set_table('employees');
$crud->set_theme('datatables');
//$crud->unset_delete();
//$crud->unset_columns('file_url');
//$crud->set_language('danish');
//$crud->set_lang_string('form_save','Save customer into the database');
$crud->set_rules('email', 'Email','trim|required|xss_clean|callback_email_check');
//$crud->add_action('More', '', 'demo/action_more','ui-icon-plus');
$output = $crud->render();

$this->_example_output($output);
}

public function email_check($str)
{
$id = $this->uri->segment(4);
if(!empty($id) && is_numeric($id))
{
$email_old = $this->db->where("id",$id)->get('employees')->row()->email;
$this->db->where("email !=",$username_old);
}

$num_row = $this->db->where('email',$str)->get('employees')->num_rows();
if ($num_row >= 1)
{
$this->form_validation->set_message('email_check', 'The email already exists');
return FALSE;
}
else
{
return TRUE;
}
}


function _example_output($output = null)

{
$this->load->view('our_template.php',$output);
}


Best Regards

Try it:


public function email_check($str)
{
$id = $this->uri->segment(4);
if(!empty($id) && is_numeric($id))
{
$email_old = $this->db->where("id", $id)->get('employees')->row()->email;
if($str==$email_old)
{
return true;
}
else
{
$query = $this->db->get_where(employees, array('email' => $str));
if($query->$query->num_rows() > 0)
{
$this->form_validation->set_message('email_check', 'The email already exists');
return false;
}
else
{
return true;
}
}
}
else
{
$query = $this->db->get_where("employees", array('email' => $str));
if($query->$query->num_rows() > 0)
{
$this->form_validation->set_message('email_check', 'The email already exists');
return false;
}
else
{
return true;
}
}
}

Hi

Stil the same with the "Loading, updating changes.." and nothing happens.

With your sugestion it is not possible to save a new record it then stop at save with the message "Loading, saving data.."

Can you show an error (of log or firebug)?
Or show the table structure

You have an error:


$this->db->where("id", $id)

You haven't field "id"!
you have a field "employeeNumber" as primary key

You can change the $config['log_threshold'] (application/config/config.php) and CI will write messages to log files.
