Validation function in helper |
[eluser]Unknown[/eluser]
Hi there, I'm actually doing a form library so i can easily build some forms in CI. I'm having different type of fields (ie: date, select, checkbox etc.) and i want to automatically do some validation using the CI library on these types of field. For example if i have a date field i want to automatically validate the field to check if it's a true date. As i'm doing that in a library i thought it would be nice to have these validation functions (is_true_date($date) or whatever) in a validation helper. What do you think of that idea ? Anyway i was trying to do that but couldn't find a way to make it work. I've been using the validation form from the documentation and just moved the username_check($str) function in a helper. I also removed the "callback_" part in the validation string as it's gonna be used as a standard function (such as is_numeric). I had to change a little bit the username_check($str) function in the helper (to get the instance into the function). Here is how it looks like now : Code: function username_check($str) The problem i'm having now is that if it try to validate the form and an error occurs the username field is filled up with what's returned by username_check($str) (1 or 0) instead of its original value. Do you have any idea why ? Shouldn't it work as if i was using is_numeric or any other function ? Thanks for your time. |
