I have a form which requires an alpha_numeric input. I set the validations and etc., and it flashes an error every time I test it out with an alpha_numeric input. The same problem occurs when I use alpha, numeric, etc. "Required" works fine.
A similar problem occurs when I used a callback function for a time input field (If you know a better way to integrate a timepicker, since grocerycrud only has the datepicker, please tell me.). In the callback function, it checks if the hours/minutes is numeric, so I used the is_numeric PHP function. However, the error message I set keeps flashing despite a correct input.
Thanks in advance for any helpful answers!
