form_error()

form_error([$field = ''[, $prefix = ''[, $suffix = '']]])

Returns a validation error message from the Form Validation Library, associated with the specified field name. You can optionally specify opening and closing tag(s) to put around the error message.

Example:

// Assuming that the 'username' field value was incorrect:
echo form_error('myfield', '<div class="error">', '</div>');

// Would produce: <div class="error">Error message associated with the "username" field.</div>
