Check if a form field has an error - El Forum - 03-25-2011

Is there a to check if a form field has an error? I don't care what the error is I just need to know if there is any error for the field.
I extended the form helper with this function but I'm not sure if there are cases where it will fail.
Code:
function field_has_error($field)
{
if (FALSE === ($OBJ =& _get_validation_object()))
{
return TRUE;
}
if ( ! isset($OBJ->_field_data[$field]['error']) OR $OBJ->_field_data[$field]['error'] == '')
{
return FALSE;
}
else
{
return TRUE;
}

Hey,
I simply do: <?php if (form_error('contact_email')) echo ' error'; ?>
If I want to add error class for example

You can set rules for each field, then test to make sure all fields passed validation.
