trigger form_error without going through the form_validation->run() - El Forum - 02-09-2010
[eluser]Dennis_gull[/eluser]
Is it possible to trigger the the form_error without using $this->form_validation->run()?
For example if a user is signing in I want the regular validation to run then after the validation I want to check the database to see if the information match anyone, if it does I need to take this information and save it in the session, example:
Code:
if( $this->form_validation->run('login_user') )
{
$result = $this->db->select('id, username, language')->from('users')->where($where)->get()->row();
if(count($result) == 1)
{
// continue with login using the $result variable
}
else
{
// trigger form error
}
}For this example I can't use a custom_validation because I need the user information after the validation and I don't want to run the query twice.

I think the anwser is no. You can try to validate your query with a Callback.

Yeah but then I won't get the query result once its validated.

I had to create a solution for this so I put the following function in my MY_form_validation.php:
Code:
function set_error($field, $message, $label = '')
{
$this->_field_data[$field]['error'] = sprintf($this->CI->lang->line($message), $this->_translate_fieldname($label));
}then you use it like this:
Code:
$this->form_validation->set_error('my_form_field','my_language_field', 'lang:my_label');
