Another registration problem...how do I check if an email is valid or not? I'm using the email helper but I can't seem to integrate it into the function properly...
Code:
function email_check($str) {
//This field is required and cannot be blank.
if ($str == '') {
$this->form_validation->set_message('email_check', 'The Email Field is Required');
return FALSE;
}
//Is the email valid?
$this->load->helper('email');
elseif (!valid_email($str)) {
$this->form_validation->set_message('email_check', 'Please Enter a Valid Email Address');
return FALSE;
}
//Does the email already exist in the database? That's a no no.
$query = $this->db->get('players');
foreach ($query->result() as $row):
$email_exist = $row->email_address;
endforeach;
elseif ($str == $email_exist)
{
$this->form_validation->set_message('email_check', 'That Email Already Exists');
return FALSE;
}
else
{
return TRUE;
}
}
Instead of checking to see if it's valid, I want to check and see if it's invalid. Is there a way to do that?
