Please just take this example as there might be a simple answer Im not aware of.
function extra_fields($form,$data)
{ $this->load->library('validation');
$sql = "SELECT * FROM prefix_extra_fields WHERE form = '".$form."'";
$query = $this->db->query($sql, array());
$build =""; //gives build an initial value of blank
foreach ($query->result() as $row)
{ // text input
if($row->type=="text"){
$name=$row->name;
$error_validation = $name."_error";
$build.='<tr>
<td class="form_label">'.$name.':</td>
<td class="form_input">'.$this->validation->$error_validation.'<input type="text" name="'.$name.'" value="'.$this->validation->$name.'" size="50" /></td>
</tr>';
}// end text input
RETURN $build;
}
What this example does is gets any extra fields for this particular form as $form lets say ‘user_register’.
I have a validation system running and working but the error message will not parse to the view.
In the above code example ‘$this->validation->$name’ is being parsed to the view, no problem, but $this->validation->$error_validation will not parse.
Lets say $error_validation = ‘username_error’, this simply does not parse the expected error to my view. However if I placed the code $this->validation->username_error directly into my view page, any error can be seen, so Im certain the validation system I have is working 100%.
If anyone who is clever knows why a validation_error cant be parsed from a function then please let me know. This is almost complete now and I am willing to share the system… if I can get it to work properly.
