Bug in validation library

[eluser]onejaguar[/eluser]
"prep_for_form" is indeed redundant; it will automatically be run on all fields if a validation error occurs and will not be run in there are no errors, even if explicitly told to run in the rules.

The "form_prep" helper function will do what you want; running in all cases. e.g.:

Code:

$this->load->helper('form');
$rules['data'] = 'trim|xss_clean|form_prep|max_length[255]|required';

Rather than changing functionality, the user manual should be updated to remove “prep_for_form” as an option in the validation rules and it should state that if there are errors, special characters are converted so that HTML data can be shown in a form field without breaking it.
